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 1 1/2-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.

WARNING

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 units in the normal UP orientation to maintain oil in

the compressor.

5. Model WPHF units should not be stacked more than three high. Do not stack

WPVJ units.

servicing could result in death or

serious injury.

Main Electrical

Verify the power supply complies

with the unit nameplate specifica-

tions.

Note: The vertical units have been

tied to the skid by (8) shipping

brackets with (16) 5/16" screws.

Remove the (8) screws attached on

the unit side, and (2) screws at-

tached at the L bracket side. The

unit may now be slid off of the

skid. Re-attach (8) of the screws

into the unit base pan.

Inspect all control panel compo-

nents; tighten any loose connec-

tions.

Connect properly sized and pro-

tected power supply wiring to a

field-supplied/installeddisconnect

switch and to the unit contactor

(1K1) in the unit’s cabinet control

box for equipment.

Verify the correct model, options

and voltage from the unit name-

plate.

Install proper grounding wires to

an earth ground.

Verify the installation location of

the unit will provide the required

clearance for proper operation.

Note: All field-installed wiring must

comply with NEC and applicable local

codes.

Remove refrigeration access panel

and inspect the unit. Be certain the

refrigerant tubing has clearance

from adjacent parts.

Low Voltage Wiring (AC & DC)

Requirements

Connect properly sized control wir-

ing to the proper termination

points between the thermostat/

sensor and the terminal board in

the unit’s control box.

Water Connection

Note: If the unit is connected to ex-

isting ductwork, an initial check of

the mechanical system should be

made to insure the duct has the ca-

pacity to handle the air required for

the unit application. If ducting is too

small, as in the replacement of heat-

ing only systems, larger ductwork

should be installed. All existing

ductwork should be checked for

leaks, and repairs should be made.

For vibration isolation, it is recom-

mended that flexible steel braided

hoses be installed instead of hard pip-

ing between the supply/return risers

and the equipment.

Additional accessories, such as a

strainer are recommended for use to

eliminate contaminants from entering

the co-axial water-to-refrigerant heat

exchangers.

minimum of 1" duct insulation.

Note: Installing the unit to an unin-

sulated ductwork in an uncondi-

tioned space may adversely affect

the unit’s performance, as well as in-

crease noise emissions into the

space.

3 Install proper condensate trapping

to the equipment. The unit drain

connection is 3/4" (19mm). When de-

signing the condensate trap, it is im-

portant to consider the unit’s draw-

thru design requiring negative pres-

sure trapping.

In a properly trapping system, when

condensate forms during normal

operation, the water level in the trap

rises until there is a constant flow

(Figure 3). It is imperative to main-

tain water in the trap and not allow

the trap to dry out during heating

season. Keeping the trap primed at

all times will enable the water to

flow properly.

Condensate piping must be installed

to allow the cleanable condensate

Connecting a Distributed Pump

Kit to a Closed Loop System

All piping external to the unit is the re-

sponsibility of the installer. The water

pipe installation must be done in ac-

cordance with local codes. If no local

code applies, national codes should be

followed. It is the contractor’s respon-

sibility to know and adhere to all appli-

cable codes.

5 With the air vented and the water

circulating, the entire system should

be checked for leaks with repairs made

as required.

6 Check and adjust the water/air level

in the expansion tank.

7 Operate the boiler (if used) by rais-

ing the loop temperature to approxi-

mately 85°F. Make 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-

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-

10 Refill the system and bleed off any

air. Add antifreeze to the system in cli-

mates where ambient temperature

falls below freezing, using the propor-

tion of antifreeze shown in Table 2.

After the piping system is complete,

cleaning and flushing the water loop

should be done to avoid trash settle-

out in the condenser (Figure 6). An ex-

tra pipe may be necessary to connect

the hose kits.

Electrical power to the unit should

be disconnected.

2 Double back the supply hose and

connect directly to the return riser

valve.

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 cannot

maintain proper flow.

3 Fill the water system with clean wa-

ter using the water make up connec-

tions. Note: Air vents should be

opened during filling.

4 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: Make up

water must be available to the system

to replace the volume formerly occu-

pied by the air that is bled off.

Calculate the approximate volume of

water in the system by using the re-

quirements detailed in Table 2. Add

three gallons to this total to allow for

the water contained in the hose kit and

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

Sequence

of Operation

Initial Unit Start-up

Start-up for 24V (basic) controls is included below:

Note: Start-up for the Tracer

ZN510 controller may be found in WSHP-IOP-2.

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 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 contained in

specification sheet data. Water leaving the heat exchanger should be warmer than the entering water temper-

ature (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.

4.Check the cooling refrigerant pressures against values in Table OP1. (Page 27).

5.Turn the thermostat 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°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 27)

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

12.Instruct the owner on system operation.

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.

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.

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.

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

Like any other type of mechanical

equipment, the unit performs best

when it is well maintained.

Operation with a Conventional

Thermostat

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.

The unit is equipped with safety con-

trols, including high pressure control

and low pressure control to shut off

the compressor under abnormal pres-

sure conditions. If the safeties shut off

the compressor, a lockout relay pre-

vents short cycling from the abnormal

condition. When conditions are cor-

rected, the lockout control can be reset

by setting the thermostat system

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 34.

• 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 34.
