Checklist

WARNING

Fiberglass Wool!

Product contains fiberglass wool. Disturbing the insulation in this

product during installation, maintenance or repair will expose you to

airborne particles of glass wool fibers and ceramic fibers known to the

state of California to cause cancer through inhalation. Glass wool fibers

may also cause respiratory, skin or eye irritation.

Jobsite Inspection

Always perform the following checks before accepting a unit:

1. Verify that the nameplate data matches the data on the sales order and bill of

lading (including electrical data).

2. Verify that the power supply complies with the unit nameplate specifica-

tions.

3. Visually inspect the exterior of the unit, for signs of shipping damage. Do not

sign the bill of lading accepting the unit(s) until inspection has been com-

pleted. Check for damage promptly after the unit(s) are unloaded. Once the

bill of lading is signed at the jobsite, the unit(s) are now the property of the

SOLD TO party and future freight claims MAY NOT be accepted by the

freight company.

4. Verify that the refrigerant charge has been retained during shipment by use

of gauges. Schrader taps are located internal to the cabinet.

5. After assuring that charge has been retained, reinstall the schrader caps to

assure that refrigerant leakage does not occur.

WARNING

Microbial Growth!

Wet interior unit insulation can become an amplification site for

microbial growth (mold), which may cause odors and serious health

related indoor air quality problems. If there is evidence of microbial

growth (mold) on the interior insulation, remove or replace the

insulation prior to operating the system. Failure to remove microbial

growth could result in serious health problems.

Jobsite Storage

This unit is intended for indoor use only. To protect the unit from damage due to

the elements, and to prevent possible IAQ contaminant sources from growing,

the unit should be stored indoors. If indoor storage is not possible, the following

provisions for outdoor storage must be met:

1. Place the unit(s) on a dry surface or raise above the ground to assure ade-

quate air circulation beneath the unit.

2. Cover the unit(s) with a water proof tarp to protect them from the elements.

3. Make provisions for continuous venting of the covered units to prevent

moisture from standing on the unit(s) surfaces. Wet interior unit insulation

can become an amplification site for microbial growth (mold) which has

been determined to be a cause of odors and serious health related indoor air

quality problems.

4. Store units in the normal UP orientation to maintain oil in the compressor.

5. Horizontal units may be stacked no more than three units high. Do not stack

the vertical unit configurations.

the space temperature, but to also re-

duce the relative humidity of the

space. When operating in the reheat

mode (meaning the sensible tempera-

ture has been met in the space), the

humidistat signals the reheat relay coil

to energize, allowing the high pres-

sure refrigerant gas to flow from the

compressor through the reheat valve,

into the reversing valve, or reheat coil

for dehumidification.

If the 1/2 through 5 ton GEH and GEV

unit incorporates the factory mounted

option, the unit will ship from the fac-

tory with an internally mounted

nichrome open wire heating element,

designed to start-up electric heat as

boilerless controller returns the unit to

normal compressor heating operation,

and locks out the electric heater.

If the unit contains a cooling only heat

pump design, the electric heat contac-

tor is wired directly to the thermostat

for primary heating, and the compres-

sor contactor for cooling.

Notes:

•

A high static blower motor is re-

quired to support the hot gas re-

heat option for the 1/2 through 5

ton equipment.

For units comprised of the field in-

stalled duct heater option, the unit will

ship from the factory with controls

available to interface with the field

provided electric heat selection.

•

Units containing the hot gas reheat

option should not be used as a

make-up air unit.

Note: For geothermal applications, the

boilerless controller has an adjustable

setting of 25, 35, 45, 55 and 60 de-

grees.

Water regulating valves should not

be used with the hot gas reheat op-

tion. Trane places a thermal expan-

sion valve on all WSHPs as well as

GSHPs to regulate refrigerant flow

vs. water flow to the unit.

(option) Supplemental or

Boilerless Electric Heat

The 6 through 25 ton models which

contain boilerless control electric heat

or supplemental electric heat will con-

tain the controls interface ONLY for

field provided electric heat selection.

The heater for this model shall be ex-

ternal to the equipment by the contrac-

tor for ease of installation. All power

connections for the electric heater will

be completely separate from the unit

for field supplied electric heat.

Note: When the unit has boilerless

control, the electric heat is not used as

supplemental electric heat, but as a

primary heat.

GEH Clearance Dimensions

Access to the unit for service pur-

poses should be provided at instal-

lation. All 1/2 through 5 ton

configurations require an 18" (457

mm) surround clearance from oth-

er mechanical and electrical equip-

ment (where shown) to enable

panel removal from the unit for

service/maintenance ability. Some

local codes require a greater ser-

vice clearance than listed below.

Check all code requirements prior

to unit installations.

Equipment containing a same-side

supply/return combination re-

quires a 3" (229 mm) limitation on

one side. Access to the TXV may

not be possible with this 3" (229

mm) clearance. This configuration

is typically applied in a corridor in-

stallation, where space limitations

force the left or right side of the

unit against a wall.

Supply-Air Ductwork

Install the 1" (25.4 mm) supply-air duct

flange to the vertical and horizontal

equipment with the (8) 5/16" (7.94 mm)

factory supplied Torx head screws.

The duct collar assembly for each unit

is located:

•

Model GEH 1/2 to 5 ton = in a box

on the side of the unit

• Model GEV 1/2 to 10ton = inside of

the refrigeration section of the unit

ry ship with a duct collar installed

for units containing a top supply-

air location. For units with a back

or front supply-air location, the

duct collar assembly must be or-

dered separately from the factory,

or be field provided.

Figure 4: Flexible supply-air connector (field provided)

When attaching the field ductwork to

the unit, provide a watertight flexible

connector at the unit to prevent oper-

ating sounds from transmitting

through the ductwork. See Figure 4.

Elbows with turning vanes or splitters

are recommended to minimize air

noise due to turbulence and to reduce

static pressure.

Installation

Dual Filtration (GEH 1/2 to 5 ton)

The horizontal, GEH model, allows the

installer flexibility in design applica-

tions such as a dual filtration option.

With the dual filtration design, the unit

will contain a lower static which trans-

lates into a decrease in filter mainte-

nance. For installation of a dual

filtration accessory for the GEH mod-

el, verify that an extra set of return-air

filter racks and filter have been or-

dered from the factory. This accessory

will be shipped separate from the unit,

and should be located in a separate

box than the unit.

(1) Remove the return-air side panel

from the GEH unit. This panel is held

in place by six Torx head screws.

Note:

The dual-filtration design is

typically used in a free-return

application.

(2) Install the top/bottom filter rack at

the new opening. The 1"/2" (25.4/50.8

mm) adjustable filter rack is held in

place with four Torx head screws that

once held the panel.

(3) Install the 1"/2" (25.4/50.8 mm)

filter.

Return-Air Duct Panel

The return-air arrangement may be

easily converted from a free return-air

system, to a ducted return-air system

with the addition of a return-air side

panel on the GEH unit. By replacing

the filter racks with the return-air pan-

el, a complete seal from the ductwork

to the unit is possible. The 1 1/2" (38

mm) duct flange facilitates ease of

field hook-up to the mechanical

system.

(1) Install the return-air duct panel to

the return-air opening with the six

Torx head screws provided for the fil-

ter rack assembly.

Note:

Installation

Sound Attenuation Pad

For sound sensitive installations, a vi-

bration pad (field provided) should be

placed beneath the horizontal or verti-

cal equipment. For the horizontal unit,

the pad should be approximately

twice the size of the unit foot print. For

the vertical unit, the pad should be 1/2"

(12.7 mm) thick, and equal to the over-

all unit foot print.

WARNING

Improper Unit Lift!

Test lift unit approximately 24

inches to verify proper center of

gravity lift point. To avoid drop-

ping of unit, reposition lifting

point if unit is not level. Failure to

properly lift unit could result in

death or serious injury or

possible equipment or prop-

erty-only damage.

Hanging the Horizontal Unit

To hang the horizontal configuration:

(1) Install the hanging isolators (locat-

ed in the return-air section of the unit)

into the four hanging brackets.

(2) Secure the equipment to a joist,

concrete, etc. with the use of 3/8"

(9.7 mm) field provided (all-thread)

rod. Each corner should contain field

provided nuts and washers to com-

plete the hanging installation.

(3) Unit slope or pitch should conform

to national and local codes. This is the

responsibility of the contractor.

Condensate Drain Connection

Install proper trapping to the equip-

ment. The unit drain connection is 3/4"

(19 mm) for all GEH and GEV models.

When designing the condensate trap

for the water-source system, it’s im-

portant to consider the unit’s draw-

thru design requiring negative pres-

sure trapping.

In a properly trapped system,

when condensate forms during

normal operation, the water level

in the trap rises until there is a

constant flow. It is imperative to

maintain water in the trap and

not allow the trap to dry out dur-

ing heating season. Keeping

trap primed at all times will

enable the water to flow

properly. See Figure 6 for

appropriate dimensions

required in a negative pressure

system.

Types of Hose Connections

Whether installing the units in a central

pump (main/auxiliary pump for the en-

tire zone) design, or as a distributed

pump (1-pump per unit) design, a shut-

off device and flexible hose is recom-

mended to transition from the hard pip-

ing of the closed or open loop water

system to the unit. There are multiple

hose combinations which may be used

to fit the design or specification criteria

for the installation.

Option 1: Flexible hoses

(1) A steel braided hose without a shut-

off device is the least expensive means

of connecting the heat pump to the sup-

ply/return water loop.

(2) With the addition of a shut-off device

on the supply and return of the system,

the unit may be isolated during service

or maintenance situation. This system

may be installed as a wide open (full wa-

ter flow to the equipment) design, or

manually balanced by utilizing the pres-

sure/temperature ports on the top of the

ball valve/shut-off device.

Option 2: Flexible hoses with ball valves

Installation

Types of Hose Connections

(3) A circuit setter provides a means of

manually balancing the water flow to

the heat pump. This manual in-line

balancing method is accurate up to

20%. In order to determine flow rate,

the user must record both handle posi-

tion, and differential pressure drop.

Then, the user must consult a chart

containing both pieces of information

and make the necessary adjustments

to the circuit setter.

(4) For self balancing flow control, a

Hays Measurflo® balancing hose kit

provides a constant flow rate over the

pressure differential range of 2 to 80

psid. As system pressures change

(through the addition of heat pumps,

for example) each individual flow con-

trol valve will automatically adjust to

the new system conditions.

Option 3: Flexible hoses with ball valves and circuit setter

Additional accessories, such as a

strainer are recommended for use to

eliminate contaminants from entering

the co-axial water-to-refrigerant heat

exchanger.

Option 4: Flexible hoses with automatic balancing flow control

be checked for leaks with repairs made

as required.

(6) Shut down pumps and supplemen-

tary heat system. Reconnect the hoses

placing the water-to-refrigerant heat

exchanger in the water circulating sys-

tem.

(1)Water circulation system should be

filled with clean water using the water

make up connections. Note: Air vents

should be open during filling.

(4) Operate the supplementary heat

system (boiler) making checks per

manufacturer’s instructions. During

this operation, visual checks should be

made for leaks that may have occurred

due to increased heat. Repair as re-

quired.

(2) With the air vents closed, start the

circulating pump and then crack the air

vents to bleed off the trapped air, as-

suring circulation through all compo-

nents of the system.

Note: Vents should be open when the

pumps and supplementary heat sys-

tem are shut down.

Installation

Connecting a

Water Regulating Valve

The water regulating valve assembly

is shipped as a separate item. Connec-

tions from the valve assembly to the

unit must be made by the installing

contractor.

Note:

Water regulating valves are most com-

monly applied with vapor-cycle refrigera-

tion systems that use capillary tube

metering devices to maintain suitable

head or suction pressure levels for proper

compressor loading. They are seldom ap-

plied when thermal expansion valves

(TXV’s) are used.

IMPORTANT: These valves are not

positive shut-off devices. Use a slow-

closing solenoid valve in the heat

pump’s leaving water line to assure

positive shut-off in variable-pump-

ing applications.

Installation for

Single Compressor Units

(1) Connect the MPT connection on

the valve assembly to the unit water

out FPT connection. Note: A field sup-

plied union or elbow may be required

to connect the water regulating valve

assembly to the unit. All field supplied

fittings should be brass or copper.

(2) Connect the valve depressor with a

1/4" (6.35 mm) flare nut to the 1/4"

(6.35 mm) schrader tap on the unit.

Note: The pressure-sensing lines from

both regulators have been "tee’d" to-

gether.

(3) Adjust the regulator head pressure

to meet specified conditions. See

Table 4.

Table 4: Typical water regulating valve

operating pressures

Note: If the unit has not been ordered

with a water regulating tap, and the

tap is field installed, it is important the

tap be made on the copper tube be-

tween the reversing valve and the wa-

ter-to-refrigerant heat exchanger. This

is the only part of the heat pump re-

frigerant circuit that serves as both a

discharge line during the cooling cy-

cle, and a suction line during the heat-

ing cycle. To avoid shavings, particles

and dirt from entering the system, it is

recommended that the 1/4" (6.35 mm)

hole be burned in the copper vs.

drilled in the copper.

Installation

Waterside Economizer

Start-up Sequence

Set the thermostat to the highest position.

Set the thermostat system switch to COOL with the fan control to AUTO. The compressor should NOT run.

Reduce the thermostat setting until the compressor, reversing valve, solenoid valve, and loop pump are energized.

Adjust water flow utilizing pressure/temperature plugs and comparing to tables contained in specification sheet data.

Water leaving the heat exchanger should be warmer than the entering water temperature (approximately 9-12ºF);

blower operation should be smooth; compressor and blower amps should be within data plate ratings; the suction

line should be cool with no frost observed in the refrigerant circuit.

Check the cooling refrigerant pressures against values in Table 7 on page 75. NOTE: If cooling mode is activated, and

the entering water temperature of the heat pump falls below 55ºF, the 2-position, water side economizing valve will

become energized (open) and compressor operation will halt allowing for free cooling in the space.

Turn the thermostat system switch to the OFF position. Unit should stop running and the reversing valve should de-

energize.

Leave unit off for approximately FIVE minutes to allow for pressure equalization.

Turn the thermostat to the lowest setting.

Set the thermostat system switch to the HEAT position.

Adjust the temperature setting upward until the unit is energized. Warm air should blow from the register. A water

temperature decrease of approximately 5-9 F leaving the heat exchanger should be noted. The blower and compressor

operation should be smooth with no frost observed in the refrigeration circuit.

10 Check the heating refrigerant pressures against values in Table 7 on page 75. NOTE: For units with boilerless electric

heat option...In heating mode, if the entering water temperature of the heat pump falls below 45ºF, the electric heater

will be energized, and compressor operation will halt. Once the entering water temperature rises above 50ºF, the boil-

erless controls returns the unit to normal operation.

11 Set the thermostat to maintain the desired space temperature.

12 Instruct the owner on system operation.

Pre-Start

Checklist

Pre-Start-up Checklist

Before energizing the unit, the following system devices must be checked:

____ Is the high voltage power supply correct and in accordance with the nameplate ratings?

____ Is phasing of the unit correct per compressor rotation (scroll compressor only)?

____ Is the field wiring and circuit protection the correct size?

____ Is the low voltage control circuit wiring correct per the unit wiring diagram?

____ Is the piping system clean/complete and correct?(A recommendation of all system flushing of debris from the water-

to-refrigerant heat exchanger, along with air purging from the water-to-refrigerant heat exchanger be done in accor-

dance with the Closed-Loop/Ground Source Heat Pump Systems Installation Guide).

____ Is vibration isolation provided? (i.e. unit isolation pad, hosekits)

____ Is unit serviceable? (See clearance specifications on pages 8 and 9).

____ Are the low/high-side pressure temperature caps secure and in place?

____ Are all the unit access panels secure and in place?

____ Is the thermostat in the OFF position?

____ Is the water flow established and circulating through all the units?

____ Is the duct work correctly sized, run, taped, insulated and weather proofed with proper unit arrangement?

____ Is the condensate line properly sized, run, trapped, pitched and primed?

____ Is the zone sensor correctly wired and in a good location?

____ Does the indoor blower turn freely without rubbing?

____ Has all work been done in accordance with applicable local and national codes?

____ Has heat transfer fluid been added in the proper mix to prevent freezing in closed system application?

Sequence

of Operation

Initial Unit Start-up

Note: Start-up for the Terminal Unit Controller (TUC) may be found in WSHP-IOP-1. Start-up for the Tracer ZN510 controller may

be found in WSHP-IOP-2. Start-up for the Tracer ZN524 controller may be found in WSHP-PRB002-EN.

Start-up with the conventional thermostat is included below:

1.Set the thermostat to the highest position.

2.Set the thermostat system switch to COOL with the fan control to AUTO. The compressor should NOT run.

3.Reduce the thermostat setting until the compressor, reversing valve, solenoid valve, and loop pump are energized.

Adjust water flow utilizing pressure/temperature plugs and comparing to tables contained in specification sheet data.

Water leaving the heat exchanger should be warmer than the entering water temperature (approximately 9-12ºF);

blower operation should be smooth; compressor and blower amps should be within data plate ratings; the suction

line should be cool with no frost observed in the refrigerant circuit.

4.Check the cooling refrigerant pressures against values in Table 7. (Page 75).

5.Turn the thermostat system switch to the OFF position. Unit should stop running and the reversing valve should de-

energize.

6.Leave unit off for approximately FIVE minutes to allow for pressure equalization.

7.Turn the thermostat to the lowest setting.

8.Set the thermostat system switch to the HEAT position.

9.Adjust the temperature setting upward until the unit is energized. Warm air should blow from the register. A water

temperature decrease of approximately 5-9ºF leaving the heat exchanger should be noted. The blower and

compressor operation should be smooth with no frost observed in the refrigeration circuit.

10.Check the heating refrigerant pressures against values in Table 7. (Page 75)

11.Set the thermostat to maintain the desired space temperature.

12.Instruct the owner on system operation.

Operation Pressures

Operating Pressures

GENERAL: There are many variables (airflow, air temperatures) in an air conditioning system that will affect operating refrigerant pressures and

temperatures. The charts below shows approximate conditions and is based on air flow at the rated SCFM, entering air at 80.6 °F(DB), 66.2 °F(WB)

in cooling, 68 °F(DB) in heating. (+)Heating data with 35 °F EWT is based on the use of an anti-freeze solution having a freezing point 20 °F lower

than the minimum expected entering temperature.

Maintenance on the unit is simplified

with the following preventive sugges-

tions:

Calcium and magnesium

Less than 350 ppm

(total hardness)

Filter maintenance must be performed

to assure proper operation of the

equipment. Filters should be inspect-

ed at least every three months, and re-

placed when it is evident they are

dirty. Filter sizing includes:

Check the contactors and relays within

the control panel at least once a year.

It is good practice to check the tight-

ness of the various wiring connections

within the control panel.

Corrosion

Hydrogen Sulfide

Sulfates

Less than 1 ppm

For units on well water, it is important

to check the cleanliness of the water-

to-refrigerant heat exchanger. Should

it become contaminated with dirt and

scaling as a result of bad water, the

heat exchanger will have to be back

flushed and cleaned with a chemical

that will remove the scale. This service

should be performed by an experi-

enced service person.

Condensate Trap

For units incorporating a negative trap

design, ensure that the condensate

system is primed with water at all

times. Allowing a negative, pressure

condensate system to run dry could

cause a break in the condensate seal

allowing the fan to draw water from

the condensate line to spray moisture

into the mechanical system. By
