Plan all connections which must be made prior to starting installation, including ducting, grilles, copper line set, condensate
drain, electrical power connections, and location of control panel. See Figure 2 for general layout example.
Select a location for the condensing unit and its support system (pad, rails or other) that provides for the minimum clearances
required for safety. This includes the clearance to combustible surfaces, airflow clearance, wiring, refrigerant piping, and service
access below, around and above unit as specified in unit drawings. Check for possible overhead obstructions which may
interfere with unit lifting or rigging. Locate the unit so that the outdoor coil (condenser) airflow is unrestricted on all sides and
above.

LEARANCES
Special considerations must be given to location of the condensing unit(s) in regard to structures, obstructions, other units, and
any other factors that may interfere with air circulation. Where possible, the top of the unit should be unobstructed, however if
vertical conditions require placement beneath an obstruction there should be a minimum of 30 inches (762 mm) between the
top of the unit and the obstruction(s). The specified dimensions meet requirements for air circulation only. Consult all
appropriate regulatory codes prior to determining final clearances.
Another important consideration in selecting location for the unit(s) is the angle to obstructions. Either coil side can be placed
toward the structure with appropriate clearance. It is not recommended for fan side to be placed towards structure. Service
access side of unit should be placed to provide adequate service clearance. Corner installations are strongly discouraged.
Refer to Figure 3 on page 6 and Figure 4, page 6 for mandatory minimum installation clearance requirements.
DO NOT locate the unit:
•
Where fresh air supply to the outdoor coil may be restricted or when recirculation from the condenser fan discharge is
possible.
•
In a well or next to high walls.
•
Where the noise would prove to be a nuisance to the owner (i.e., salons, decks, sleeping cabins, etc.).
