Installation-Water Connections

Location Consideration

!Unit should be placed on a level surface in a indoor protected area. Units should not be installed or stored in an exterior environment.

!There should be approximately 2 to 3 feet of clearance available for accessing the unit for service.

Accessiblity into unit is made by re- moving (2) two screws at the base of

the system. (See Figure 2).

The top half of the cube then lifts off.

Remove these two screws for internal unit maintenance.

Figure 2: Unit access.

Water Connections

The loop water connections brought to the unit should be 1-inch male national pipe threads.

The desuperheater (optional) connec- tions should be 1/2-inch male national pipe threads.

(See Figure 3 for water hook-up loca- tions).

Refrigeration Connections

The refrigeration piping connections are copper stub-outs. All refrigeration connections are to be soldered into the unit. It may be necessary to provide an adapter to connect to the chosen air handler. (See Figure 4 for location and

sizes).

Note:

All refrigeration piping between the air handler and the heat pump should be ade- quately insulated. Water piping should also be insulated to reduce heat transfer and the forming of condensation.
