Pre-installation

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 specifications.

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 external to the cabinet on the 2-ton

through 6-ton equipment.

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

assure that refrigerant leakage does not occur.

CAUTION

Microbial Growth!

Wet interior unit insulation can become an amplification site for

microbial growth (mold), which may cause odors and damage to the

equipment and building materials. If there is evidence of microbial

growth (mold) on the interior insulation, the insulation should be

removed and replaced prior to operating the system.

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 refrigeration units (chassis) units in the normal UP orientation to main-

tain oil in the compressor. Cabinet configurations may be stored as crated.

5. Do not stack units.

around the compressor enclosure to

achieve greater acoustical reductions.

Water-to-Refrigerant Coils

Schrader Connections

The co-axial water-to-refrigerant heat

exchanger for the 3/4-ton through 3-

ton equipment is constructed of cop-

per or cupro-nickel (option) for the wa-

ter section and stainless steel for the

refrigeration section.

Controls

Connections for the low and high side

of the refrigeration system are located

conveniently on the chassis’ top be-

neath a sheet metal plate.

The control system offered to control

the unit is a Basic 24 volt control for

the 3/4-ton through 2-ton retrofit

(WPRD) equipment. A 50 VA trans-

former is factory supplied on this unit

configuration. See wiring diagram on

chassis access panel for field wiring

connection to the 24 volt mechanical

thermostat.

The heat exchanger is leak tested to

assure there is no cross leakage be-

tween the water and refrigerant gas.

Supply Air Ductwork

1 A 2" (50.8 mm) duct flange (field

provided) may be required to help

eliminate supply air from recirculat-

ing back into the return air, air-to-re-

frigerant coil prior to discharging

into the space.

2 Equipment containing a top dis-

charge, ducted design: install field

ductwork to the unit providing a wa-

ter tight flexible connector at the

unit. This helps prevent operating

sounds from transmitting through

the ductwork. Elbows with turning

vanes or splitters are recommended

to minimize air noise due to turbu-

lence and to help reduce static pres-

sure.

IMPORTANT

5 With the air vented and the water

circulating, the entire system

should be checked for leaks with re-

pairs made as required.

6 Operate the supplementary heat

system making checks per manu-

facturer’s instructions. During this

operation, visual checks should be

made for leaks that may have oc-

curred due to increased heat. Re-

pair as required.

WARNING

Ensure the gasket material creates a

positive seal around the entire coil to

avoid coil bypass.

Live Electrical

Components!

During installation, testing, ser-

vicing and troubleshooting of this

product, it may be necessary to

work with live electrical compo-

nents. Have a qualified licensed

electrician or other individual

who has been properly trained in

handling live electrical compo-

nents perform these tasks. Failure

to follow all electrical safety pre-

cautions when exposed to live

electrical components could re-

sult in death or serious injury.

If a field supplied door is used, ensure

the front cover is attached to the build-

ing structure and not the unit cabinet.

Supply Grille installation

See Table 2 for supply air dimensions.

Install the supply grille(s) into the

cabinet discharge opening. Insure

there are no air gaps between the

cabinet supply air and the grille.

This helps prevent recirculation of

supply air into the return air open-

ing behind the drywall.

7 Open the system at the lowest point

for the initial blow down (making

sure the make up water is equal to

the water being dumped). Continue

blow down until the water leaving

the drain runs clear, but not less

than 2 hours.

7 Flush system. See Cleaning and

Flushing the Water Loop for flushing

instructions.

8 Open the unit water valves and

check piping for leaks.

Secure grille(s) into the drywall via

two screws.

8 Shut down pumps and supplemen-

tary heat system. Reconnect the

hoses placing the water-to-refriger-

ant heat exchanger in the water cir-

culating system.

Cleaning and Flushing

the Water Loop

After the piping system is complete,

the flexible hose connectors should be

doubled back to complete the water

circuit external to the unit (avoiding

trash settle-out in the condenser). An

extra pipe may be necessary to con-

nect the hose kits. See Page 15 for an-

tifreeze/water mixture by volume.

Table 3: Antifreeze requirements based on volume

Using Antifreeze

In areas of the country where entering

water temperatures drop below 45°F

or where piping is being run through

areas subject to freezing, the loop

must be freeze protected by using an

approved antifreeze solution to pre-

vent the earth loop water from freez-

ing inside the heat exchanger.

Methanol and glycols are the most

commonly used antifreeze solutions.

Consult your geothermal unit supplier

for locally approved solutions in your

area.

Propylene Glycol

Propylene glycol is not recommended

in installations where the water tem-

perature are expected to fall below

30°F. At extreme temperatures, the vis-

cosity increases to the point where

normal loop circulating pumps may

not maintain proper flow.

If propylene glycol is the only locally

approved solution for anti-freeze,

good engineering practices should be

used to achieve the desired flow.

Calculate the approximate volume of

water in the system by using the re-

quirements detailed in Table 8, Water

Volume. Add three gallons to this total

to allow for the water contained in the

hose kit and geothermal unit.

WARNING

Live Electrical Components!

During installation, testing, servicing and troubleshooting of this product, it may be necessary to work with

live electrical components. Have a qualified licensed electrician or other individual who has been properly

trained in handling live electrical components perform these tasks. Failure to follow all electrical safety pre-

cautions when exposed to live electrical components could result in death or serious injury.

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 temperature control setting until the compressor, reversing valve, solenoid valve, and loop

pump are energized. Adjust water flow utilizing pressure/temperature plugs and comparing to tables con-

tained in specification sheet data. Water leaving the heat exchanger should be warmer than the entering

water temperature (approximately 9°F-12°F); 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 OP1. (Page 21).

Turn the thermostat 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°F-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 OP1. (Page 21)

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

12. Instruct the owner on system operation.

Flow Checks

For the operating temperature drop (heating) and rise (cooling), refer to Table OP1 and OP2 for the proper water tempera-

ture change. Depending on the unit size, entering water temperature and water flow rate, the cooling temperature rise is

from 8°F-16°F. Based on the same criteria for heating, the temperature drop is from 2°F-13°F.

Pressure

Using the P/T ports and one 0-60 psi pressure gauge with the P/T port adapter, measure the pressure difference between

the water-in and water-out connections. Compare the pressure differential to Table 6 to determine flow.

Troubleshooting

General Operation

WARNING

The standard model is designed for in-

door installation. When the unit is in-

stalled in an unconditioned space, the

unit may not start in cool weather (ap-

proximately 45°F). It may then be nec-

essary to start the unit in the cooling

mode for three to five minutes. The

unit may then be shut-off (there will be

a two minute time-out of the unit), and

restarted in the heating mode. The

freeze protection thermostat should

also be checked as it may be adversely

affected by ambient temperature.

Like any other type of mechanical

equipment, the unit performs best

when it is well maintained.

Hazardous Service

Procedures!

The maintenance and trouble

shooting procedures recommend-

ed in this section of the manual

could result in exposure to electri-

cal, mechanical or other potential

safety hazards. Always refer to

the safety warnings provided

throughout this manual concern-

ing these procedures. When possi-

ble, disconnect all electrical

power including remote discon-

nects before servicing. Follow

proper lockout/tagout procedures

to ensure the power can not be in-

advertently energized. When nec-

essary to work with live electrical

components, have a qualified li-

censed electrician or other indi-

vidual who has been trained in

handling live electrical compo-

nents per these tasks. Failure to

follow all of the recommended

safety warnings provided, could

result in death or serious injury.

Operation with a Conventional

Thermostat

The unit is equipped with safety con-

trols, including high pressure control,

low pressure control and a freeze pro-

tection thermostat, set to shut off the

compressor under abnormal tempera-

ture or pressure conditions. If the safe-

ties shut off the compressor, a lockout

relay prevents short cycling from the

abnormal condition. When conditions

are corrected, the lockout control can

be reset by setting the thermostat sys-

tem switch to OFF wait a few minutes

for the system pressure to equalize,

and then return to HEAT or COOL. If

the condition continues, an authorized

service person should check out the

unit.

Preliminary Trouble Inspection

If operational difficulties are encoun-

tered, be sure to perform the prelimi-

nary checks before referring to the

troubleshooting chart on page 28.

• Verify that the unit is receiving elec-

tric supply power.

• Ensure that the fuses in the fused

disconnect are intact.

After completing the preliminary

checks, inspect the unit for other obvi-

ous problems such as leaking connec-

tion, broken or disconnected wires,

etc. If everything appears to be in or-

der, but the unit still fails to operate

properly, refer to the troubleshooting

chart on page 28.
