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.

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.
