CLEARANCES AND ACCESSIBILITY
The condensing unit is designed to be located outside the
building with unobstructed condenser air inlet and
discharge. Additionally, the unit must be situated to permit
access for service and installation. Condenser air enters
from three sides. Air discharges upward from the top of
the unit. Refrigerant tube electrical connections are made
on the right side of the unit as you face the compressor
compartment. The best and most common application is
for the unit to be located 10” from the back wall with the
connection side facing the wall. Refer to Figures 1 and 2.

This “close to the wall” application minimizes exposed
** 1 1/8" required for full ratings
tubing and wiring and reduces the space for children to
run around the unit. This will help to avoid possible
damage to the tubes or wiring and/or personal injury.

Close to the wall application assures free, unobstructed
air to the other two sides. In more confined application
spaces, such as corners, provide a minimum 10” clearance
on all air inlet sides. Allow 18” minimum for service access
to the compressor compartment and controls.
The top of the unit should be completely unobstructed. If
units are to be located under an overhang, there should
be a minimum of 36” clearance and provisions made to
deflect the warm discharge air out from the overhang.
LOCATION
If unit is to be located under an overhang, there should be
a minimum of 36” clearance and provisions made to deflect
the water discharge air out from the overhang. If the
outdoor unit is mounted above the air handler, the
maximum lift should not exceed 70’ (suction line). If air
handler is mounted above condensing unit, the lift should
not exceed 50’ (liquid line.). Refer to Figure 3 and Table 1
for maximum refrigerant line lenghts.
