Location selection
Before starting the installation, find and select a suitable location for both the indoor and outdoor unit
using the guidelines listed previously. Observe all limitations and clearance requirements. The outdoor unit
must have sufficient clearance for air to enter and discharge from the condenser coil, as well as for service
access.
Note: For multiple unit installations, units must be spaced a minimum of 18 in (457 mm) apart. (Coil
face to coil face.) If the unit is to be installed on a roof or a black-topped ground area where it will
be exposed to the heat of the sun, the unit should be raised sufficiently above the roof or ground
to avoid the unit from taking in the accumulated heat of those surfaces. Provide adequate struc-
tural support.

Install the Unit
The unit may be installed at ground level on a solid base that will not shift or settle, as unnecessary
movement could cause strain on the refrigerant lines and possible leaks to occur. Maintain the
clearances shown in
Fig.9-2
and install the unit in a level position. Normal operating sound levels
may be undesirable if the unit is placed directly under windows of certain rooms (bedrooms, study,
etc.). The top of unit discharge area must be unrestricted for a minimum 6 feet above the unit.
