PREPARING THE CONDENSING UNIT (continued)
Installing the Condensing Unit
The condensing unit can be installed inside a well-ventilated area of the home, but 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 20 amp
circuit (non-GFI). Make sure there is a minimum three-foot horizontal clearance in the front and rear of the unit. The
unit may either be hard wired or plug-in, depending on local electrical codes.
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 unit’s overall performance. Make sure there is a minimum
three-foot horizontal clearance in the front and rear of the condensing unit and at least one foot 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 three feet of clearance in the front and rear of the unit and one foot on each side. The unit should
be elevated 18 inches in order to avoid any possible flooding or damage by animals, and should be clear of
leaves, dirt, and other debris.
