PREPARING THE CONDENSING UNIT (continued)
Installing the Condensing Unit
The Condensing Unit can be installed inside a well ventilated area of the home, but it is typically installed outside. Exterior
applications will require the use of a protective housing, and the amount of sun exposure should be considered when selecting
the placement of the Condensing Unit. The Condensing Unit requires a dedicated 20amp circuit, non-GFI. Make sure there is a
minimum 3 ft. horizontal clearance in the front and rear of the unit. The unit should be plugged in.
Set the Condensing Unit level and with proper clearances in accordance with the instructions, name plate power supplied,
proper electric disconnect, and fuse protection connected but not turned on and ready for piping connections.
Inside Condensing Unit Installations:
Inside installations require special consideration, as there must be adequate ventilation to remove the heat created
during normal operations. An exhaust port with fan may need to be installed to ensure that heat is effectively removed
from the utility room. A return grille or provision for 500 - 600 cfm of cool air to enter the room to replace the exhausted
air will accomplish this. Unobstructed airflow to and from the unit is a critical factor in the units overall performance.
Make sure there is a minimum 3 ft. horizontal clearance in the front and rear of the Condensing Unit and at least 1 ft. on
each side. This will assure that the unit can move the air around the room in an efficient manner.
Outdoor Condensing Unit Installations:
You must utilize the exterior Condensing Unit housing for outdoor installations. Place the Condensing Unit on a solid
foundation in a location with adequate ventilation. There should be 3 ft. of clearance in the front and rear of the unit and
1 ft. on each side. The unit should be elevated 18” in order to avoid any possible flooding or damage by animals, and
should be clear of leaves, dirt, and other debris.
Fan Cycling Switch:
These switches are used to cycle the condenser fan at low ambient temperature conditions.
Refrigeration Lines:
A 1/4 inch O/D copper liquid line is required.
The refrigerant drier and the sight glass shall be installed (in that order) in the direction of the refrigerant flow in the liquid line
between the Condensing Unit and Evaporator Unit (Fan Coil Unit). Enclose the suction line in a cellular insulation ½” wall thickness
Armaflex (brand name) or equal to reduce heat transfer and prevent the suction line from sweating.
