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:

Verify that the nameplate data

matches the data on the sales order

and bill of lading (including electrical

data).

Verify that the power supply

complies with the unit nameplate

specifications.

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 completed. 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.

Verify that the refrigerant charge has

been retained during shipment by

use of gauges. Schrader taps are

located internal to the cabinet.

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:

Place the unit(s) on a dry surface or

raise above the ground to assure

adequate air circulation beneath the

unit.

Cover the unit(s) with a water proof

tarp to protect them from the

elements.

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.

Store units in the normal UP

orientation to maintain oil in the

compressor.

Horizontal units may be stacked no

more than three units high. Do not

stack the vertical unit configurations.

Unit Nameplate

The unit nameplate is located on the

outside of the control box access

panel at the front of the unit. It

includes the unit model number,

serial number, electrical

characteristics, refrigerant charge,

and other pertinent unit data.

Compressor Nameplate

The nameplate for the compressors

are located on the compressor shell.

Unit Description

Before shipment, each unit is leak

tested, dehydrated, charged with

refrigerant and run tested for proper

control operation.

Air-to-Refrigerant Coil

The air-to-refrigerant coil is

aluminum fin, mechanically bonded

to the copper tubing.

Water-to-Refrigerant Coil

The water-to-refrigerant coil is a

copper or cupro-nickel (option) and

steel tube (tube-within-a-tube)

design, leak tested to assure there is

no cross leakage between the water

tube (copper/cupro-nickel) and

refrigerant gas (steel tube).

Controls

The control system offered to control

the unit is a Basic 24 Volt control for

the 1/2 through 5 ton sizes, a Deluxe

24 Volt control option for all unit

sizes, a Tracer™ ZN510, LonTalk™

certified control option for the 1/2

through 5 ton unit sizes, or a Tracer

ZN524, LonTalk certified control

option for all unit sizes.

All power wiring to the equipment is

made at the unit contactor for the 1/2

through 5 ton, and at the high

voltage terminal block for the 6

through 25 ton. All low voltage

wiring is made at the unit’s low

voltage terminal board.

System Input Devices and

Functions

A thermostat, zone sensor or

building automation system is

required to operate the water-source

heat pump. The flexibility of having

several mode capabilities depends

upon the type of sensor and/or

remote panel selected.

General Information

6WSHP-SVX01E-EN

General Information

Troubleshooting and connection

diagrams for the 24 Volt control

systems may be located in the back

of this manual. All digital control

troubleshooting tips and connection

diagrams are located in WSHP-IOP-2

(ZN510) or WSHP-PRB002-EN

(ZN524).

Basic 24V Controls

Safety devices for equipment

containing the basic 24V control

option include a low pressure switch

or suction line temperature sensor to

prevent compressor operation during

low temperature activity. The switch

or sensor is set to activate at

refrigerant pressures of 20 psig (1/2

to 5 ton units) or 7 psig (6 to 25 ton

units) to fit most applications.

A high pressure switch prevents

compressor operation during high or

excessive discharge pressures

exceeding 395 psig.

The lockout relay communicates the

low or high pressure situation to the

compressor to prevent operation. For

units that contain a condensate

overflow switch option, a condensate

overflow situation will also be

communicated to the compressor

through the lockout relay if an

overflow condition exists. The relay

may be reset at the thermostat, or by

cycling power to the unit.

General alarm is accomplished

through the lockout relay and is used

in driving light emitting diodes

(LEDs). This feature will drive dry

contacts only, and cannot be used to

drive field installed control inputs.

Trane recommends 3 minute or

greater minimum off time for

compressor control.

Deluxe 24V Controls (option)

Units containing the Deluxe 24V

control design will incorporate a

microprocessor-based control board.

The Trane microprocessor board is

factory wired to a terminal strip to

provide all necessary terminals for

field connection. The deluxe board is

equipped with a random start relay,

anti-short cycle timer, brown out

protection, compressor disable,

condensate overflow, unit safety

control, diagnostics and a generic

relay (which may be available for

field use). SeeTa b l e 3 4 for diagnostic

information and Figure 62 and

Figure 63 for thermostat connections.

Trane recommends 3 minute or

greater minimum off time for

compressor control.

Tracer ZN510 or ZN524

Controls (option)

The digital ZN510 and ZN524

controller is designed to support the

1/2 through 25 ton water-source heat

pumps in either a standalone, peer-

to-peer with a Tracer Loop Controller,

or as a full building automation

(open protocol) system. The 1/2

through 5 ton units that incorporate

direct digital controls will typically

come equipped with the ZN510

control board. The exception to this

would be if the equipment contained

hot gas reheat, waterside

economizer, or boilerless control with

electric heat. The ZN524 digital

control board is designed to interface

and run these mechanical options. All

units over 5 tons would ship with the

Tracer ZN524 control board.

For installation, operation and

diagnostics of the ZN510 and ZN524

WSHP-IOP-2 (ZN510) and/or WSHP-

PRB002-EN (ZN524).

Waterside Economizer

(option)

Instructions for mechanical

connection of the waterside

economizer to the water-source heat

pump may be found in the

dimensional section of this manual.

The waterside economizer is

designed to begin economizing

mode when water temperatures fall

below the field adjustable

temperature of 25, 35, 45, 55 or 65 F

(for the Deluxe control option), or

below the programmed set-point (for

the ZN524 control option).

When the temperature is less than

the setpoint, fluid will flow into the

economizing coil, while

simultaneously halting mechanical

operation of the compressor.

Mechanical cooling will continue on a

call for a second stage from the

thermostat or system control.

Boilerless Control/Electric

Heat (option)

Systems that do not contain a boiler

may contain a boilerless control with

electric heat. Trane offers both a

factory mounted electric heat option,

and a field mounted duct heater

option.

If the 1/2 through 5 ton GEH and GEV

unit incorporates the factory

mounted option, the unit will ship

from the factory with an internally

mounted nichrome open wire

heating element, designed to start-up

electric heat as the systems primary

heat in the event entering water

temperature falls below 55 F. Once

the entering water temperature rises

above 60 F, the 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

contactor is wired directly to the

thermostat for primary heating, and

the compressor contactor for

cooling.

For units comprised of the field

installed duct heater option, the unit

will ship from the factory with

controls available to interface with

the field provided electric heat

selection.

Note: For geothermal applications,

the boilerless controller has

an adjustable setting of 25,

35, 45, 55 and 60 degrees.

Supplemental or Boilerless

Electric Heat (option)

The 6 through 25 ton models which

contain boilerless control electric

heat or supplemental electric heat

will contain the controls interface

ONLY for field provided electric heat

selection. The heater for this model

shall be external to the equipment by

the contractor for ease of installation.

All power connections for the electric

WSHP-SVX01E-EN 7

General Information

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.

Hot Gas Reheat (option)

With the reheat option, the return-air

from the space is conditioned by the

air-to-refrigerant coil, then reheated

by the reheat coil to control not only

the space temperature, but to also

reduce the relative humidity of the

space. When operating in the reheat

mode (meaning the sensible

temperature has been met in the

space), the humidistat signals the

reheat relay coil to energize, allowing

the high pressure refrigerant gas to

flow from the compressor through

the reheat valve, into the reversing

valve, or reheat coil for

dehumidification.

A switching relay has been provided

for the reheat application to adjust

the blower motor from normal

operation to low speed when the hot

gas reheat is energized (for 1/2

through 5 ton equipment only).

Note: A high static blower motor is

required to support the hot

gas reheat option for the 1/2

through 5 ton equipment.

Note: Units containing the hot gas

reheat option should not be

used as a make-up air unit.

Note: Water regulating valves

should not be used with the

hot gas reheat option. Trane

places a thermal expansion

valve on all WSHPs as well as

GSHPs to regulate refrigerant

flow vs. water flow to the

unit.

GEH Clearance

Dimensions

Access to the unit for service

purposes should be provided at

installation. All 1/2 through 5 ton

configurations require an 18" (457

mm) surround clearance from other

mechanical and electrical equipment

(where shown) to enable panel

removal from the unit for service/

maintenance ability. Some local

codes require a greater service

clearance than listed below. Check all

code requirements prior to unit

installations.

Equipment containing a same-side

supply/return combination requires

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

installation, where space limitations

force the left or right side of the unit

against a wall.

Service clearance dimensions for the

6 through 15 ton horizontal includes

a two side access appropriate for

control and blower motor/wheel

access. Some local codes require a

greater service clearance than listed

below. Check all code requirements

prior to unit installations.
