Clearances
The location MUST allow for minimum clearances and
should not be adjacent to a patio or other area where the
unit's operating sound level might be objectionable. Local
codes MUST be observed.
Minimum clearances, as specified belowand in FIGURE 1,
MUST be maintained from adjacent structures to provide
adequate air circulation and room for service personnel.
While minimum clearances are acceptable for safety rea-
sons, they may not allow adequate air circulation around
the unit for proper operation in the cooling mode. Whenev-
er possible, it is desirable to allow additional clearance, es-
pecially around the condenser inlet and discharge
openings.
Do NOT install the unit in a location that will permit dis-
charged air from the condenser to recirculate to the con-
denser inlet.
Access Panels
CAUTION
Unit will NOT operate properly without all access pan-
els in place.
