Before starting the installation, select and check the suitability

of the location for both the indoor and outdoor unit. Observe all

limitations and clearance requirements, see Figure 2.

The outdoor unit must have sufficient clearance for air entrance

to the condenser coil, for air discharge and for service access.

If the unit is to be installed on a hot sun exposed roof or a

black-topped ground area, the unit should be raised sufficiently

above the roof or ground to avoid taking the accumulated layer

of hot air into the outdoor unit.

Provide an adequate structural support.

The unit may be installed at ground level on a solid base that

will not shift or settle, causing strain on the refrigerant lines and

possible leaks. Maintain the clearances shown Figure 2 and

install the unit in a level position. Isolate the base from the

building structure to avoid noise or vibration transmission.

When installing units on a roof, the structure must be capable

of supporting the total weight of the unit, including a pad, lintels,

rails, etc., which should be used to minimize the transmission

of sound or vibration into the conditioned space.

Isolate the unit from rain gutters to avoid any possible wash out

of the foundation.

Normal operating sound levels may be objectionable if the unit

is placed directly under windows of certain rooms (bedrooms,

study, etc.).

Condensate will drain from beneath the coil of the outdoor unit

during the defrost cycle. Normally this condensate may be

allowed to drain directly onto the ground. A gravel bed may be

used to prevent mud splashing.

WARNING: The outdoor unit should not be installed in an area

where mud or ice could cause personal injury.

Remember that condensate will drip from the unit

coils during heat and defrost cycles and that this

condensate will freeze when the temperature of the

outdoor air is below 32 ° F.

Elevate the unit sufficiently to prevent any blockage of the air

entrances by snow in areas where there will be snow accumu-

lation. Check the local weather bureau for the expected snow

accumulation in your area.
