The installation of geothermal heat pump units and all

associated components, parts and accessories which

make up the installation shall be in accordance with

the regulations of ALL authorities having jurisdiction

and MUST conform to all applicable codes. It is the

responsibility of the Installing Contractor to determine

and comply with ALL applicable codes and regulations.

General Unit Location

Locate the unit in an indoor area that allows easy removal

of the ﬁ lter and access panels, and has enough space

for service personnel to perform maintenance or repair.

Provide sufﬁ cient room to make water, electrical and duct

connection(s). If the unit is located in a conﬁ ned space,

such as a closet, provisions must be made for return air to

freely enter the space by means of a louvered door, etc.

Any access panel screws that would be difﬁ cult to remove

after the unit is installed should be removed prior to

setting the unit. These units are not approved for outdoor

installation and, therefore, must be installed inside the

structure being conditioned. Do not locate in areas where

ambient conditions are not maintained with 40-100°F and

up to 75% relative humidity.

Vertical Units Location and Access

Vertical Units are typically installed in a ﬂ oor level

closet, basement, or in a small mechanical room. Install

units with adequate clearance to allow maintenance and

servicing. Conform to the following guidelines when

selecting unit location:

1. Provide adequate clearance for ﬁ lter replacement and

drain pan cleaning. Do not block ﬁ lter access with

piping, conduit or other materials. Refer to the unit

catalog for Vertical Unit Dimensions.

2. Provide access for fan and fan motor maintenance

and for servicing the compressor and coils without

removing the unit. Note: GT-X compressor and

refrigerant circuit service requires that left side

access be provided.

3. Provide an unobstructed path to the unit within the

closet or mechanical room. Space should be sufﬁ cient

to allow removal of the unit, if necessary.

4. Provide access to water valves and ﬁ ttings and

screwdriver access to the unit side panels, discharge

collar and all electrical connections.

Setting Vertical Units

Vertical units are available in left or right air return

conﬁ gurations. Vertical units should be mounted level on

a vibration absorbing pad or extruded polystyrene slightly

larger than the base to provide isolation between the unit

and the ﬂ oor. It is not necessary to anchor the unit to the

ﬂ oor (see Figure 1a).

INSTALLATION

Duct System

A ﬁ eld installed air outlet bracket is provided on vertical

units to facilitate duct connection. A ﬂ exible connector

is recommended for both discharge and return air duct

connections on metal duct systems. Uninsulated duct

should be insulated with a minimum of one-inch duct

insulation. Application of the unit to uninsulated ductwork

in an unconditioned space is not recommended as the

unitʼs performance will be adversely affected.

If the unit is connected to existing ductwork, a previous

check should have been made to assure the ducts have the

capacity to handle the air required for the unit. If ducting

is too small, as in the replacement of heating only systems,

larger ductwork should be installed. All existing ductwork

should be checked for leaks and repaired as necessary.

The duct system should be sized to handle the design airﬂ ow

quietly. To maximize sound attenuation of the unit blower,

the supply and return plenums should include internal duct

liner of glass ﬁ ber or be of ductboard construction for the

ﬁ rst few feet. If air noise or excessive air ﬂ ow is a problem,

the airﬂ ow can be changed. See the Blower Performance and

Fan Speed sections for further instruction.

Air Coil

To obtain maximum performance, the air coil should be

cleaned before start-up. A 10% solution of dishwasher

detergent and water is recommended for both sides of

coil, a thorough water rinse should follow.

Water Connections

The GT-X Heat Exchanger water connections are swivel

piping ﬁ ttings that accept a 1" Male Pipe Thread (MPT)

connector. The swivel connector has a rubber gasket seal

similar to a garden hose gasket, which when mated to the

ﬂ ush end of any 1" threaded pipe provides a leak-free seal

without the need for thread sealing tape or compound.

Check to insure that the rubber seal is in the swivel

connector prior to attempting any connection (the rubber

seals are shipped attached the swivel connector). DO

NOT OVERTIGHTEN or leaks may occur.
