PROTECTION — Once the units are properly positioned on
the jobsite, they must be covered with either a shipping carton,
vinyl film, or an equivalent protective covering. Open ends of
pipes stored on the jobsite must be capped. This precaution is
especially important in areas where painting, plastering, or
spraying of fireproof material, etc. is not yet complete. Foreign
material that is allowed to accumulate within the units can pre-
vent proper start-up and necessitate costly clean-up operations.
• ALLOW enough space for service personnel to perform
maintenance.
• Provisions must be made for return air to freely enter the
space if unit needs to be installed in a confined area such
as a closet.
Step 4 — Mount the Unit — Vertical units are avail-
able in rear or front return air configurations.
DISCHARGE CONFIGURATION CONVERSION — To
change the discharge configuration of the unit from top dis-
charge to straight (right or left) discharge, follow the procedure
below. To change the discharge configuration of the unit from
straight (right or left) discharge to top discharge, reverse the
procedure below.
Before installing any of the system components, be sure to
examine each pipe, fitting, and valve, and remove any dirt or
foreign material found in or on these components.
CAUTION
1. Remove the 3 panels as shown in Fig. 4.
DO NOT store or install units in corrosive environments or
in locations subject to temperature or humidity extremes
(e.g., attics, garages, rooftops, etc.). Corrosive conditions
and high temperature or humidity can significantly reduce
performance, reliability, and service life. Always move
units in an upright position. Tilting units on their sides may
cause equipment damage.

INSPECT UNIT — To prepare the unit for installation, com-
plete the procedures listed below:
C-BOX/
MOTOR ACCESS
PANEL
1. Compare the electrical data on the unit nameplate with
ordering and shipping information to verify that the
correct unit has been shipped.
2. Do not remove the packaging until the unit is ready for
installation.

3. Verify that the unit’s refrigerant tubing is free of kinks or
dents, and that it does not touch other unit components.
a50-8466
4. Inspect all electrical connections. Be sure connections are
clean and tight at their terminations.
Fig. 4 — Remove Panels
5. Loosen compressor bolts until the compressor rides freely
on springs. Remove shipping restraints.
6. Remove the four 1/4 in. (6 mm) shipping bolts from com-
pressor support plate (two bolts on each side) to maxi-
mize vibration and sound alternation.
2. Remove blockoff air handler. Loosen belt and remove.
See. Fig. 5.
a50-8467
BLOCKOFF
AIR HANDLER
CAUTION
Failure to remove shipping brackets from spring-mounted
compressors will cause excessive noise and could cause
component failure due to added vibration.
7. Remove any blower support cardboard from inlet of the
blower.
8. Locate and verify any accessory kit located in compressor
and/or blower section.
Fig. 5 — Remove Blockoff Air Handler and Belt
9. Remove any access panel screws that may be difficult to
remove once unit is installed.
3. Remove 4 bolts from blower panel. Remove 4 bolts (2
bolts on each side) from blower sides. See Fig. 6.
Step 3 — Locate Unit — The following guidelines
should be considered when choosing a location for a WSHP:
• Units are for indoor use only.
STEP 3
• Locate in areas where ambient temperatures are between
4.4 C and 37.8 C and relative humidity is no greater than
75%.
a50-8468
• Provide sufficient space for water, electrical and duct
connections.
NOTE: Water inlets/outlets and high/low voltage electrical
access are available on either side of the unit. Electrical ac-
cess is also available on the unit front. See Fig. 2 and 3.
STEP 3
• Locate unit in an area that allows for easy access and
removal of filter and access panels.

Step 5 — Check Duct System — The duct system
should be sized to handle the design airflow quietly.
NOTE: Depending on the unit, the fan wheel may have a ship-
ping support installed at the factory. This must be removed
before operating unit.
STEP 6
SOUND ATTENUATION — To eliminate the transfer of
vibration to the duct system, a flexible connector is recom-
mended for both discharge and return air duct connections on
metal duct systems. The supply and return plenums should in-
clude internal duct liner of fiberglass or be made of duct board
construction to maximize sound attenuation of the blower.
Installing the WSHP unit to uninsulated ductwork in an uncon-
ditioned space is not recommended since it will sweat and
adversely affect the unit’s performance.
To reduce air noise, at least one 90-degree elbow could be
included in the supply and return air ducts, provided system
performance is not adversely impacted. The blower speed can
be also changed in the field to reduce air noise or excessive air-
flow, provided system performance is not adversely impacted.
Fig. 21 — Move Bolt-Belt Adjustment Assembly
7. Put belt back on and tighten. Put control box cover and
motor cover on return side. See Fig. 22.
EXISTING DUCT SYSTEM — If the unit is connected to
existing ductwork, consider the following:
a50-8484
• Verify that the existing ducts have the proper capacity to
handle the unit airflow. If the ductwork is too small,
larger ductwork should be installed.
• Check existing ductwork for leaks and repair as
necessary.
NOTE: Local codes may require ventilation air to enter the
space for proper indoor air quality. Hard-duct ventilation may
be required for the ventilating air supply. If hard ducted venti-
lation is not required, be sure that a proper air path is provided
for ventilation air to unit to meet ventilation requirement of the
space.

Step 6 — Install Condensate Drain — The con-
densate drain can be connected to either side of the unit. The
50VQP units come with a flex hose and 1 in. (25 m) FPT con-
densate connection tied inside. To install the condensate drain
(see Fig. 24.):
Fig. 22 — Replace Belt and Motor and

• If condensate pump is present on unit, be sure drain con-
nections have a check valve to prevent back flow of con-
densate into other units.
a50-8486
Step 7 — Pipe Connections — Depending on the
application, there are 3 types of WSHP piping systems to choose
from: water loop, ground-water and ground loop. Refer to the
Carrier System Design Manual for additional information.
All WSHP units utilize low temperature soldered female
pipe thread fittings for water connections to prevent annealing
and out-of-round leak problems which are typically associated
with high temperature brazed connections. Refer to Table 1 for
connection sizes. When making piping connections, consider
the following:
• A backup wrench must be used when making screw con-
nections to unit to prevent internal damage to piping.
• Insulation may be required on piping to avoid condensa-
tion in the case where fluid in loop piping operates at
temperatures below dew point of adjacent air.
• Piping systems that contain steel pipes or fittings may
be subject to galvanic corrosion. Dielectric fittings may
be used to isolate the steel parts of the system to avoid
galvanic corrosion.
Fig. 24 — Install Condensate Drain
Each unit must be installed with its own individual trap,
vent and means to flush or blow out the condensate drain line.
Do not install units with a common trap or vent. See Fig. 25.
WATER LOOP APPLICATIONS — Water loop applications
usually include a number of units plumbed to a common pip-
ing system. Maintenance to any of these units can introduce air
into the piping system. Therefore, air elimination equipment
comprises a major portion of the mechanical room plumbing.
Vent
The flow rate is usually set between 2.41 and 3.23 L/m per
kW of cooling capacity. For proper maintenance and servicing,
pressure-temperature (P/T) ports are necessary for temperature
and flow verification.
In addition to complying with any applicable codes, consid-
er the following for system piping:
*3/4" IPT
Trap Depth
1.5" [38mm]
Min 1.5"
[38mm]
3/4" PVC or
Copper by others
1/4" per foot
(21mm per m)
drain slope
NOTE: Trap should be deep enough to offset maximum unit static
difference.
• Piping systems utilizing water temperatures below
10.0 C require 13 mm closed cell insulation on all piping
surfaces to eliminate condensation.
Fig. 25 — Trap Condensate Drain
• All plastic to metal threaded fittings should be avoided
due to the potential to leak. Use a flange fitted substitute.
• Teflon tape thread sealant is recommended to minimize
internal fouling of the heat exchanger.
• Use backup wrench. Do not overtighten connections.
• Route piping to avoid service access areas to unit.
• The piping system should be flushed prior to operation to
remove dirt and foreign materials from the system.
Consider the following:
• Units are typically installed directly above each other on
successive floors with condensate drains located near the
units.
• Connect the unit condensate drain connection to the
building condensate drain with a 1-in. (25 mm) drain
line.
• The horizontal run of a condensate hose is usually too
short to cause drainage problems, however the horizontal
run pitch of the condensate line should be at least 1 cm
for every 50 cm of run in the direction of flow. Avoid low
points and unpitched piping since dirt collects in low or
level areas and may cause stoppage and overflow.
• Install a condensate trap at each unit with the top of
the trap positioned below the unit condensate drain
connection.
• Design the length of the trap (water-seal) based upon the
amount of positive or negative pressure on the drain pan.
As a rule, 25 mm of trap is required for each 10 Pa of
negative pressure on the unit.
GROUND-LOOP APPLICATIONS — Temperatures be-
tween –3.9 and 43.3 C and a cooling capacity of 2.41 to
3.23 L/s per kW are recommended. In addition to comply-
ing with any applicable codes, consider the following for
system piping:
• Piping materials should be limited to only polyethylene
fusion in the buried sections of the loop.
• Galvanized or steel fittings should not be used at any
time due to corrosion.
• All plastic to metal threaded fittings should be avoided
due to the potential to leak. Use a flange fitted substitute.
• Do not overtighten connections.
• Route piping to avoid service access areas to unit.
• Pressure-temperature (P/T) plugs should be used to mea-
sure flow of pressure drop.
VENTING — A vent should be installed in the condensate
line of any application which may allow dirt or air to collect in
the line. Consider the following:
GROUND-WATER APPLICATIONS — Typical ground-
water piping is shown in Fig. 26. In addition to complying
with any applicable codes, consider the following for sys-
tem piping:
• Install shut-off valves for servicing.
• Install pressure-temperature plugs to measure flow and
temperature.
• Always install a vent where an application requires a
long horizontal run.
• Always install a vent where large units are working
against higher external static pressure and to allow
proper drainage for multiple units connected to the same
condensate main.
• Be sure to support the line where anticipated sagging
from the condensate or when “double trapping” may
occur.
10
Download from Www.Somanuals.com. All Manuals Search And Download.
• Boiler drains and other valves should be connected using
a “T” connector to allow acid flushing for the heat
exchanger.
POWER CONNECTION — Line voltage connection is
made by connecting the incoming line voltage wires to the
L side of the CC terminal. See Tables 3 and 4 for correct
wire and maximum overcurrent protection sizing.
• Do not overtighten connections.
• Route piping to avoid service access areas to unit.
• Use PVC SCH80 or copper piping material.
NOTE: PVC SCH40 should not be used due to system high
pressure and temperature extremes.
Water Supply and Quantity — Check water supply. Water
supply should be plentiful and of good quality. See Table 2 for
water quality guidelines.
SUPPLY VOLTAGE — Operating voltage to unit must be
within voltage range indicated on unit nameplate.
On 3-phase units, voltages under load between phases must
be balanced within 2%. Use the following formula to deter-
mine the percentage voltage imbalance:
% Voltage Imbalance
max voltage deviation from average voltage
= 100 x
IMPORTANT: Failure to comply with the above required
water quality and quantity limitations and the closed-
system application design requirements may cause damage
to the tube-in-tube heat exchanger that is not the responsi-
bility of the manufacturer.
average voltage
Example: Supply voltage is 420-3-50.
AB = 425 volts
BC = 422 volts
AC = 417 volts
In all applications, the quality of the water circulated
through the heat exchanger must fall within the ranges listed in
the Water Quality Guidelines table. Consult a local water treat-
ment firm, independent testing facility, or local water authority
for specific recommendations to maintain water quality within
the published limits.

Determine maximum deviation from average voltage:
(AB) 425 – 421 = 4 v
(BC) 422 – 421 = 1 v
(AC) 421 – 418 = 3 v
To avoid possible injury or death due to electrical shock,
open the power supply disconnect switch and secure it in
an open position during installation.
Maximum deviation is 4 v.
Determine percent voltage imbalance.

types of conductors.
= 0.95%
This amount of phase imbalance is satisfactory as it is
below the maximum allowable 2%.
Operation on improper line voltage or excessive phase
imbalance constitutes abuse and may cause damage to electri-
cal components.
All field-installed wiring, including the electrical ground,
MUST comply with the National Electrical Code (NEC) as
well as applicable local codes. In addition, all field wiring must
conform to the Class II temperature limitations described in the
NEC.
Refer to unit wiring diagrams Fig. 27-30 for a schematic of
the field connections which must be made by the installing (or
electrical) contractor. See Tables 3 and 4 for fuses sizes.
Consult the unit wiring diagram located on the inside of the
compressor access panel to ensure proper electrical hookup.
The installing (or electrical) contractor must make the field
connections when using field-supplied disconnect.
NOTE: If more than 2% voltage imbalance is present, contact
local electric utility.
420-VOLT OPERATION — All 380/420 volt units are factory
wired for 380 volts. The transformers may be switched to
420-volt operation (as illustrated on the wiring diagram) by
disconnecting the VIO lead at L1 and attaching the BRN lead
to L1. Close open end of VIO lead.
Operating voltage must be the same voltage and phase as
shown in electrical data shown in Tables 3 and 4.
Make all final electrical connections with a length of flexi-
ble conduit to minimize vibration and sound transmission to
the building.

HWG — Hot Water Generator
HX — Heat Exchanger
Sulfides in the water quickly oxidize when exposed to air, requiring that no agi-
tation occur as the sample is taken. Unless tested immediately at the site, the
sample will require stabilization with a few drops of one Molar zinc acetate
solution, allowing accurate sulfide determination up to 24 hours after sam-
pling. A low pH and high alkalinity cause system problems, even when both
values are within ranges shown. The term pH refers to the acidity, basicity, or
neutrality of the water supply. Below 7.0, the water is considered to be acidic.
Above 7.0, water is considered to be basic. Neutral water contains a pH of 7.0.

WATER SOLENOID VALVES — An external solenoid
valve(s) should be used on ground water installations to shut
off flow to the unit when the compressor is not operating. A
slow closing valve may be required to help reduce water
hammer. Figure 33 shows typical wiring for a 24-vac external
solenoid valve. Figures 34 and 35 illustrate typical slow closing
water control valve wiring for Taco 500 Series and Taco ESP
Series valves. Slow closing valves take approximately 60 sec.
to open (very little water will flow before 45 sec.). Once fully
open, an end switch allows the compressor to be energized (on-
ly on valves with end switches). Only relay or triac based elec-
tronic thermostats should be used with slow closing valves.
When wired as shown, the slow closing valve will operate
properly with the following notations:

THERMOSTAT CONNECTION
NOTE: Low voltage connector may be removed for
easy installation.
IMPORTANT: Connecting a water solenoid valve can
overheat the anticipators of electromechanical thermo-
stats. Only use relay based electronic thermostats.

WATER FREEZE PROTECTION — The Aquazone control
allows the field selection of source fluid freeze protection
points through jumpers. The factory setting of jumper JW3
(FP1) is set for water at –1.1 C. In earth loop applications,
jumper JW3 should be clipped to change the setting to –12.2 C
when using antifreeze in colder earth loop applications. See
Fig. 32.

PRE-START-UP
ACCESSORY CONNECTIONS — Terminal labeled A on
the control is provided to control accessory devices such as
water valves, electronic air cleaners, humidifiers, etc. This
signal operates with the compressor terminal. See Fig. 33.
Refer to the specific unit wiring schematic for details.
System Checkout — When the installation is complete,
follow the system checkout procedure outlined below before
starting up the system. Be sure:
1. Voltage is within the utilization range specifications of the
unit compressor and fan motor and voltage is balanced
for 3-phase units.
TERMINAL STRIP P2
2. Fuses, breakers and wire are correct size.
3. Low voltage wiring is complete.
4. Piping and system flushing is complete.
5. Air is purged from closed loop system.
6. System is balanced as required. Monitor if necessary.
7. Isolation valves are open.

cause premature belt failure and or intermittent airflow. An
overly tight belt can cause premature motor or blower bear-
ing failure. To adjust the belt tension, follow the procedure
outlined below:
1. Remove belt from motor sheave.
2. Lift motor assembly.
3. Loosen the 5/16-in. hex nuts on the grommet motor adjust-
ment bolts (2 per bolt). To increase the belt tension loosen
the top hex nut. To decrease the belt tension loosen the
bottom hex nut.
17. Control field-selected settings are correct.
4. Turn the bolts by hand to the desired position then tighten
AIR COIL — To obtain maximum performance, the air coil
should be cleaned before starting the unit. A 10% solution of
dishwasher detergent and water is recommended for both sides
of the coil. Rinse thoroughly with water.
the 5/16-in. hex nuts (2 per bolt).
5. Lower the motor assembly.
6. Install the belt.
7. The belt tension can be adjusted by using one of the fol-
lowing methods:
Airflow and External Static Pressure — The
50VQP units are available with standard, low, and high-static
factory-installed options. These options will substitute a differ-
ent blower drive sheave for each static range. In addition, cer-
tain static ranges may require the optional large fan motor.
SHEAVE ADJUSTMENT — The 50VQP units are supplied
with a variable sheave drive on the fan motor to adjust for dif-
fering airflows at various ESP (external static pressure) condi-
tions. See Tables 5-12 for unit airflows. When fully closed, the
sheave will produce the highest static capability (higher rpm).
To adjust sheave position, follow the procedure outlined below:
1. Loosen belt tension and remove belt.
2. Loosen set screw on fan motor.
3. Open sheave to desired position.
4. Retighten set screw and replace belt.
NOTE: Set belt tension as outlined below.
a. Tighten until belt deflects approximately 13 mm
with very firm finger pressure.
b. Grasp belt midway between two pulleys and twist
for a 90-degreerotation.
NOTE: Adjusting less than 90degreeswill over-
tighten the belt and adjusting more than 90degrees
will loosen belt.
c. Set proper belt tension to 32 to 36 kg.
NOTE: The motor position should not need adjustment. Motor
sheave position is at mid position of each sheave. For example,
the motor sheave is 2.5 turns open on a 5-turn sheave. The belt
tension adjustment can also be accomplished by turning the
5/16-in. hex nuts to the desired position.
NOTE: Available airflows for all units are shown in
Tables 5-12.
BELT TENSION ADJUSTMENT — An overly loose belt
will, upon starting motor, produce a slippage “squeal” and

control has 2 DIP switch blocks. Each DIP switch block has
8 switches and is labeled either S1 or S2 on the circuit board.
See Fig. 28.
DIP SWITCH BLOCK 1 (S1) — This set of switches offers
the following options for Deluxe D control configuration:
Performance Monitor (PM) — Set switch 1 to enable or dis-
able performance monitor. To enable the PM, set the switch to
ON. To disable the PM, set the switch to OFF.
Compressor Relay Staging Operation — Switch 2 will enable
or disable compressor relay staging operation. The compressor
relay can be set to turn on with stage 1 or stage 2 call from the
thermostat. This setting is used with dual stage units (units with
2 compressors and 2 Deluxe D controls) or in master/slave ap-
plications. In master/slave applications, each compressor and
fan will stage according to its switch 2 setting. If switch is set to
stage 2, the compressor will have a 3-second delay before ener-
gizing during stage 2 demand.
Jumpers and DIP (dual in-line package) switches on the
control board are used to customize unit operation and can be
configured in the field.
IMPORTANT: Jumpers and DIP switches should only be
clipped when power to control board has been turned off.

Fig. 27)
WATER COIL FREEZE PROTECTION (FP1) LIMIT
SETTING — Select jumper 3, (JW3-FP1 Low Temp) to
choose FP1 limit of –12.2 C or –1.1 C. To select –1.1 C as the
limit, DO NOT clip the jumper. To select –12.2 C as the limit,
clip the jumper.
AIR COIL FREEZE PROTECTION (FP2) LIMIT SET-
TING — Select jumper 2 (JW2-FP2 Low Temp) to choose
FP2 limit of –12.2 C or –1.1 C. To select –1.1 C as the limit,
DO NOT clip the jumper. To select –12.2 C as the limit, clip
the jumper.
NOTE: If DIP switch is set for stage 2, the alarm relay will not
cycle during Test mode.
Heating/Cooling Thermostat Type — Switch 3 provides selec-
tion of thermostat type. Heat pump or heat/cool thermostats
can be selected. Select OFF for heat/cool thermostats. When in
heat/cool mode, Y1 is used for cooling stage 1, Y2 is used for
cooling stage 2, W1 is used for heating stage 1 and O/W2 is
used for heating stage 2. Select ON for heat pump applications.
In heat pump mode, Y1 used is for compressor stage 1, Y2 is
used for compressor stage 2, W1 is used for heating stage 3 or
emergency heat, and O/W2 is used for RV (heating or cooling)
depending upon switch 4 setting.
O/B Thermostat Type — Switch 4 provides selection for heat
pump O/B thermostats. O is cooling output. B is heating out-
put. Select ON for heat pumps with O output. Select OFF for
heat pumps with B output.
ALARM RELAY SETTING — Select jumper 1 (JW1-AL2
Dry) for connecting alarm relay terminal (AL2) to 24 vac (R) or
to remain as a dry contact (no connection). To connect AL2 to
R, do not clip the jumper. To set as dry contact, clip the jumper.
Complete C Control DIP Switches — The Com-
plete C control has 1 DIP switch block with five switches. See
Fig. 27.
PERFORMANCE MONITOR (PM) — DIP switch 1 will
enable or disable this feature. To enable the PM, set the switch
to ON. To disable the PM, set the switch to OFF.
STAGE 2 — DIP switch 2 will enable or disable compressor
delay. Set DIP switch to OFF for stage 2 in which the compres-
sor will have a 3-second delay before energizing.
NOTE: The alarm relay will not cycle during Test mode if
switch is set to OFF, stage 2.
Dehumidification Fan Mode — Switch 5 provides selection
of normal or dehumidification fan mode. Select OFF for dehu-
midification mode. The fan speed relay will remain OFF dur-
ing cooling stage 2. Select ON for normal mode. The fan speed
relay will turn on during cooling stage 2 in normal mode.
DIP SWITCH 3 — not used.
DIP SWITCH 4 — not used.
Switch 6 — Not used.
DIP SWITCH 5 — DIP switch 5 is used to initiate 1 or 3 tries
for the FP1 fault. If water freeze protection for the water coil
then DIP switch 5 can be set to lock out on the FP1 fault after
one try.
Boilerless Operation — Switch 7 provides selection of boil-
erless operation and works in conjunction with switch 8. In
boilerless operation mode, only the compressor is used for
heating when FP1 is above the boilerless changeover tempera-
ture set by switch 8 below. Select ON for normal operation or
select OFF for boilerless operation.
Deluxe D Control Jumper Settings (See
Fig. 28)
WATER COIL FREEZE PROTECTION (FP1) LIMIT
SETTING — Select jumper 3, (JW3-FP1 Low Temp) to
choose FP1 limit of –12.2 C or –1.1 C. To select –1.1 C as the
limit, DO NOT clip the jumper. To select –12.2 C as the limit,
clip the jumper.
AIR COIL FREEZE PROTECTION (FP2) LIMIT SET-
TING — Select jumper 2 (JW2-FP2 Low Temp) to choose
FP2 limit of –12.2 C or –1.1 C. To select –1.1 C as the limit,
DO NOT clip the jumper. To select –12.2 C as the limit, clip
the jumper.
ALARM RELAY SETTING — Select jumper 4 (JW4-AL2
Dry) for connecting alarm relay terminal (AL2) to 24 vac (R) or
to remain as a dry contact (no connection). To connect AL2 to
R, do not clip the jumper. To set as dry contact, clip the jumper.
LOW PRESSURE SETTING — The Deluxe D Control can
be configured for Low Pressure Setting (LP). Select jumper 1
(JW1-LP Norm Open) for choosing between low pressure in-
put normally opened or closed. To configure for normally
closed operation, do not clip the jumper. To configure for nor-
mally open operation, clip the jumper.
Boilerless Changeover Temperature — Switch 8 on S1 pro-
vides selection of boilerless changeover temperature set point.
Select OFF for set point of 10.0 C or select ON for set point
of 4.4 C.
If switch 8 is set for 10.0 C, then the compressor will be
used for heating as long as the FP1 is above 10.0 C. The com-
pressor will not be used for heating when the FP1 is below
10.0 C and the compressor will operate in emergency heat
mode, staging on EH1 and EH2 to provide heat. If a thermal
switch is being used instead of the FP1 thermistor, only the
compressor will be used for heating mode when the FP1 termi-
nals are closed. If the FP1 terminals are open, the compressor is
not used and the control goes into emergency heat mode.
DIP SWITCH BLOCK 2 (S2) — This set of DIP switches is
used to configure accessory relay options. See Fig. 28.
Switches 1 to 3 — These DIP switches provide selection of
Accessory 1 relay options. See Table 13 for DIP switch
combinations.

Start Up System
1. Restore power to system.
2. Turn thermostat fan position to ON. Blower should start.
3. Balance airflow at registers.
4. Adjust all valves to the full open position and turn on the
line power to all heat pump units.
5. Operate unit in the cooling cycle. Room temperature
should be approximately 10 to 38 C dry bulb. Loop water
temperature entering the heat pumps should be between
10 and 49 F.
NOTE: Three factors determine the operating limits of a
unit: (1) entering-air temperature, (2) water temperature and
(3) ambient temperature. Whenever any of these factors are
at a minimum or maximum level, the other two factors must
be at a normal level to ensure proper unit operation. See
Table 15.
Deluxe D Control Accessory Relay Configura-
tions — The following accessory relay settings are applica-
ble for both Deluxe D controls only:
CYCLE WITH FAN — In this configuration, the relay will be
ON any time the Fan Enable relay is on.
CYCLE WITH COMPRESSOR — In this configuration, the
relay will be ON any time the Compressor relay is on.
DIGITAL NIGHT SET BACK (NSB) — In this configura-
tion, the relay will be ON if the NSB input is connected to
ground C.
NOTE: If there are no relays configured for digital NSB, then
the NSB and override (OVR) inputs are automatically config-
ured for mechanical operation.
MECHANICAL NIGHT SET BACK — When NSB input is
connected to ground C, all thermostat inputs are ignored. A
thermostat set back heating call will then be connected to the
OVR input. If OVR input becomes active, then the Deluxe D
control will enter Night Low Limit (NLL) staged heating
mode. The NLL staged heating mode will then provide heating
during the NSB period.
WATER VALVE (SLOW OPENING) — If relay is config-
ured for Water Valve (slow opening), the relay will start 60 sec-
onds prior to starting compressor relay.
OUTSIDE AIR DAMPER (OAD) — If relay is configured
for OAD, the relay will normally be ON any time the Fan
Enable relay is energized. The relay will not start for 30 min-
utes following a return to normal mode from NSB, when NSB
is no longer connected to ground C. After 30 minutes, the relay
will start if the Fan Enable is set to ON.
Scroll Compressor Rotation — It is important to be
certain compressor is rotating in the proper direction. To
determine whether or not compressor is rotating in the proper
direction:
1. Connect service gages to suction and discharge pressure
fittings.
2. Energize the compressor.
3. The suction pressure should drop and the discharge
pressure should rise, as is normal on any start-up.

erant pressures.
5. Once the unit has begun to run, check for warm air deliv-
ery at the unit grille.
6. Check air temperature rise across the coil when compres-
sor is operating. Air temperature rise should be between
11° C and 17° C after 15 minutes at load.

7. Check for vibration, noise and water leaks.
Flow Regulation — Flow regulation can be accom-
plished by two methods. Most water control valves have a flow
adjustment built into the valve. By measuring the pressure drop
through the unit heat exchanger, the flow rate can be deter-
mined using Table 17. Adjust the water control valve until the
flow of 0.09 to 0.13 L/s is achieved. Since the pressure con-
stantly varies, two pressure gages may be needed in some
applications.
An alternative method is to install a flow control device.
These devices are typically an orifice of plastic material de-
signed to allow a specified flow rate that are mounted on the
outlet of the water control valve. Occasionally these valves
produce a velocity noise that can be reduced by applying
some back pressure. To accomplish this, slightly close the
leaving isolation valve of the well water setup.
If the suction pressure does not drop and the discharge
pressure does not rise to normal levels:
1. Turn off power to the unit. Install disconnect tag.
2. Reverse any two of the unit power leads.
3. Reapply power to the unit and verify pressures are correct.
The suction and discharge pressure levels should now move
to their normal start-up levels.
When the compressor is rotating in the wrong direction, the
unit makes an elevated level of noise and does not provide
cooling.
After a few minutes of reverse operation, the scroll com-
pressor internal overload protection will open, thus activating
the unit lockout. This requires a manual reset. To reset, turn the
thermostat on and then off.
WARNING
NOTE: There is a 5-minute time delay before the compressor
will start.
To avoid possible injury or death due to electrical shock,
open the power supply disconnect switch and secure it in
an open position before flushing system.
Unit Start-Up Cooling Mode
1. Adjust the unit thermostat to the warmest position.
Slowly reduce the thermostat position until the compres-
sor activates.
2. Check for cool air delivery at unit grille a few minutes
after the unit has begun to operate.
3. Verify that the compressor is on and that the water flow
rate is correct by measuring pressure drop through the
heat exchanger using P/T plugs. See Table 16. Check the
elevation and cleanliness of the condensate lines; any
dripping could be a sign of a blocked line. Be sure the
condensate trap includes a water seal.
4. Check the temperature of both supply and discharge wa-
ter. If temperature is within acceptable range, proceed. If
temperature is outside the range, check the cooling refrig-
erant pressures.
Flushing — Once the piping is complete, final purging
and loop charging is needed. A flush cart pump of at least
1.5 hp is needed to achieve adequate flow velocity in the
loop to purge air and dirt particles from the loop. Flush the
loop in both directions with a high volume of water at a high
velocity. Follow the steps below to properly flush the loop:
1. Verify power is off.
2. Fill loop with water from hose through flush cart be-
fore using flush cart pump to ensure an even fill. Do
not allow the water level in the flush cart tank to drop
below the pump inlet line to prevent air from filling
the line.
3. Maintain a fluid level in the tank above the return tee
to avoid air entering back into the fluid.
4. Shutting off the return valve that connects into the
flush cart reservoir will allow 345 kPa surges to help
purge air pockets. This maintains the pump at 345 kPa.
5. Check air temperature drop across the coil when com-
pressor is operating. Air temperature drop should be
between 8 and 14 C.
5. To purge, keep the pump at 345 kPa until maximum
pumping pressure is reached.
Table 16 — Water Temperature Change
Through Heat Exchanger
6. Open the return valve to send a pressure surge through
the loop to purge any air pockets in the piping system.
7. A noticeable drop in fluid level will be seen in the
flush cart tank. This is the only indication of air in the
loop.

FREEZE PROTECTION SELECTION — The –1.1 C FP1
factory setting (water) should be used to avoid freeze damage
to the unit.
Once antifreeze is selected, the JW3 jumper (FP1) should
be clipped on the control to select the low temperature
(antifreeze –12.2 C) set point to avoid nuisance faults.

NOTE: If air is purged from the system while using a
250 mm PVC flush tank, only a 25 to 50 mm level drop will
be noticed since liquids are incompressible. If the level
drops more than this, flushing should continue since air is
still being compressed in the loop. If level is less than 25 to
50 mm, reverse the flow.

Loop static pressure will fluctuate with the seasons. Pres-
sures will be higher in the winter months than during the
warmer months. This fluctuation is normal and should be
considered when charging the system initially. Run the unit
in either heating or cooling for several minutes to condition
the loop to a homogenous temperature.
When complete, perform a final flush and pressurize the
loop to a static pressure of 275 to 350 kPa for winter months
or 100 to 140 kPa for summer months.
After pressurization, be sure to remove the plug from the
end of the loop pump motor(s) to allow trapped air to be
discharged and to ensure the motor housing has been flood-
ed. Be sure the loop flow center provides adequate flow
through the unit by checking pressure drop across the heat
exchanger.
Cooling Tower/Boiler Systems — These systems
typically use a common loop maintained at 15.6 C to 32.2 C.
The use of a closed circuit evaporative cooling tower with a
secondary heat exchanger between the tower and the water
loop is recommended. If an open type cooling tower is
used continuously, chemical treatment and filtering will be
necessary.
Ground Coupled, Closed Loop and Plateframe
Heat Exchanger Well Systems — These systems
allow water temperatures from –1.1 to 43.3 C. The external
loop field is divided up into 51 mm polyethylene supply and
return lines. Each line has valves connected in such a way
that upon system start-up, each line can be isolated for flush-
ing using only the system pumps. Air separation should be
located in the piping system prior to the fluid re-entering the
loop field.
Antifreeze — In areas where entering loop temperatures
drop below 4.4 C or where piping will be routed through ar-
eas subject to freezing, antifreeze is needed.
OPERATION
Alcohols and glycols are commonly used as antifreeze
agents. Freeze protection should be maintained to 8.3° C below
the lowest expected entering loop temperature. For example, if
the lowest expected entering loop temperature is –1.1 C, the
leaving loop temperature would be –5.6 to –3.9 C. Therefore,
the freeze protection should be at –9.4 C (–1.1 C – 8.3 C =
–9.4 C) Calculate the total volume of fluid in the piping sys-
tem. See Table 18. Use the percentage by volume in
Power Up Mode — The unit will not operate until all
the inputs, terminals and safety controls are checked for
normal operation.
NOTE: The compressor will have a 5-minute anti-short
cycle upon power up.

STANDBY — Y and W terminals are not active in Standby
mode, however the O and G terminals may be active, de-
pending on the application. The compressor will be off.
COOLING — Y and O terminals are active in Cooling
mode. After power up, the first call to the compressor will
initiate a 5 to 80 second random start delay and a 5-minute
anti-short cycle protection time delay. After both delays are
complete, the compressor is energized.
NOTE: On all subsequent compressor calls the random start
delay is omitted.
HEATING STAGE 1 — Terminal Y is active in heating
stage 1. After power up, the first call to the compressor will
initiate a 5 to 80 second random start delay and a 5-minute
anti-short cycle protection time delay. After both delays are
complete, the compressor is energized.
NOTE: On all subsequent compressor calls the random start
delay is omitted.
HEATING STAGE 2 — To enter Stage 2 mode, terminal W
is active (Y is already active). Also, the G terminal must be
active or the W terminal is disregarded. The compressor re-
lay will remain on and EH1 is immediately turned on. EH2
will turn on after 10 minutes of continual stage 2 demand.
NOTE: EH2 will not turn on (or if on, will turn off) if FP1

COOLING STAGE 1 — In Cooling Stage 1 mode, the Fan
Enable, compressor and RV relays are turned on immediate-
ly. If configured as stage 2 (DIP switch set to OFF) then the
compressor and fan will not turn on until there is a stage 2
demand. The Fan Enable and compressor relays are turned
off immediately when the Cooling Stage 1 demand is re-
moved. The control reverts to Standby mode. The RV relay
remains on until there is a heating demand. If there is a mas-
ter/slave or dual compressor application, all compressor re-
lays and related functions will track with their associated
DIP switch 2 on S1.
COOLING STAGE 2 — In Cooling Stage 2 mode, the Fan
Enable, compressor and RV relays remain on. The Fan
Speed relay is turned on immediately and turned off once
the Cooling Stage 2 demand is removed. The control reverts

Retry Mode — In Retry mode, the status LED will start to
flash slowly to signal that the control is trying to recover from
an input fault. The control will stage off the outputs and try to
again satisfy the thermostat used to terminal Y. Once the ther-
mostat input calls are satisfied, the control will continue normal
operation.
NOTE: If 3 consecutive faults occur without satisfying the
thermostat input call to terminal Y, the control will go into
lockout mode. The last fault causing the lockout is stored in
memory and can be viewed by entering Test mode.
IMPORTANT: To avoid fouled machinery and extensive
unit clean-up, DO NOT operate units without filters in
place. DO NOT use equipment as a temporary heat source
during construction.
Condensate Drain Pans — Check condensate drain
pans for algae growth twice a year. If algae growth is apparent,
consult a water treatment specialist for proper chemical treat-
ment. The application of an algaecide every three months will
typically eliminate algae problems in most locations.
Aquazone™ Deluxe D Control LED Indica-
Refrigerant System — Verify air and water flow rates
are at proper levels before servicing. To maintain sealed circuit-
ry integrity, do not install service gages unless unit operation
appears abnormal.
tors — There are 3 LED indicators on the Deluxe D control:
STATUS LED — Status LED indicates the current status or
mode of the Deluxe D control. The Status LED light is green.
TEST LED — Test LED will be activated any time the De-
luxe D control is in Test mode. The Test LED light is yellow.
FAULT LED — Fault LED light is red. The fault LED will
always flash a code representing the last fault in memory. If
there is no fault in memory, the fault LED will flash code 1 and
appear as 1 fast flash alternating with a 10-second pause. See
Table 22.
Condensate Drain Cleaning — Clean the drain line
and unit drain pan at the start of each cooling season. Check
flow by pouring water into drain. Be sure trap is filled to main-
tain an air seal.
Air Coil Cleaning — Remove dirt and debris from evap-
orator coil as required by condition of the coil. Clean coil with
a stiff brush, vacuum cleaner, or compressed air. Use a fin
comb of the correct tooth spacing when straightening mashed
or bent coil fins.
SERVICE
Perform the procedures outlined below periodically, as
indicated.
Condenser Cleaning — Water-cooled condensers may
require cleaning of scale (water deposits) due to improperly
maintained closed-loop water systems. Sludge build-up may
need to be cleaned in an open water tower system due to
induced contaminants.
Local water conditions may cause excessive fouling or
pitting of tubes. Condenser tubes should therefore be cleaned at
least once a year, or more often if the water is contaminated.
Proper water treatment can minimize tube fouling and
pitting. If such conditions are anticipated, water treatment
analysis is recommended. Refer to the Carrier System Design
Manual, Part 5, for general water conditioning information.
IMPORTANT: When a compressor is removed from this
unit, system refrigerant circuit oil will remain in the com-
pressor. To avoid leakage of compressor oil, the refrigerant
lines of the compressor must be sealed after it is removed.
IMPORTANT: All refrigerant discharged from this unit
must be recovered without exception. Technicians must fol-
low industry accepted guidelines and all local, state and fed-
eral statutes for the recovery and disposal of refrigerants.
IMPORTANT: To avoid the release of refrigerant into the
atmosphere, the refrigerant circuit of this unit must only be
serviced by technicians which meet local, state and federal
proficiency requirements.
CAUTION
Follow all safety codes. Wear safety glasses and rubber
gloves when using inhibited hydrochloric acid solution.
Observe and follow acid manufacturer’s instructions. Fail-
ure to follow these safety precautions could result in per-
sonal injury or equipment or property damage.
IMPORTANT: To prevent injury or death due to electrical
shock or contact with moving parts, open unit disconnect
switch before servicing unit.
Clean condensers with an inhibited hydrochloric acid solu-
tion. The acid can stain hands and clothing, damage concrete,
and, without inhibitor, damage steel. Cover surroundings to
guard against splashing. Vapors from vent pipe are not harmful,
but take care to prevent liquid from being carried over by the
gases.
Filters — Filters must be clean for maximum performance.
Inspect filters every month under normal operating conditions.
replace when necessary.
IMPORTANT: Units should never be operated with-
out a filter.
Warm solution acts faster, but cold solution is just as effec-
tive if applied for a longer period.
GRAVITY FLOW METHOD — Do not add solution faster
than vent can exhaust the generated gases.
When condenser is full, allow solution to remain overnight,
then drain condenser and flush with clean water. Follow acid
manufacturer’s instructions. See Fig. 36.
FORCED CIRCULATION METHOD — Fully open vent
pipe when filling condenser. The vent may be closed when
condenser is full and pump is operating. See Fig. 37.
Regulate flow to condenser with a supply line valve. If
pump is a nonoverloading type, the valve may be fully closed
while pump is running.
Water Coil — Keep all air out of the water coil. Check
open loop systems to be sure the well head is not allowing air
to infiltrate the water line. Always keep lines airtight.
Inspect heat exchangers regularly, and clean more frequent-
ly if the unit is located in a “dirty” environment. The heat
exchanger should be kept full of water at all times. Open loop
systems should have an inverted P trap placed in the discharge
line to keep water in the heat exchanger during off cycles.
Closed loop systems must have a minimum of 100 kPa during
the summer and 275 kPa during the winter.
Check P trap frequently for proper operation.
For average scale deposit, allow solution to remain in con-
denser overnight. For heavy scale deposit, allow 24 hours.

for R-410A, find equivalent saturated condensing
temperature.
5. Read liquid line temperature on thermometer; then
subtract from saturated condensing temperature. The dif-
ference equals subcooling temperature.
Control Sensors — The control system employs 2 nom-
inal 10,000 ohm thermistors (FP1 and FP2) that are used for
freeze protection. Be sure FP1 is located in the discharge fluid
and FP2 is located in the air discharge. See Fig. 39.
