LOCATION

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.

The outdoor unit must have sufficient clearance for air

entrance to the condenser coil, for air discharge and for ser-

vice access. See Figure 1.

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

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

ciently above the roof or ground to avoid taking the accumu-

lated layer of hot air into the outdoor unit.

Provide an adequate structural support.

GROUND INSTALLATION

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 in Figure

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

the structure to avoid noise or vibration transmission.

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 (bed-

rooms, study, etc.).

ROOF INSTALLATION

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

of supporting the total weight of the unit, including a pad, lin-

tels, rails, etc., which should be used to minimize the trans-

mission of sound or vibration into the conditioned space.

UNIT PLACEMENT

Provide a base in the pre-determined location.

Remove the shipping carton and inspect for possible

damage.

Compressor tie-down bolts should remain tightened.

Position the unit on the base provided.

Sit unit on the (4) rubber elevating grommets if provided.

Use grommet kit 1SG0601 if not provided. These should

be positioned as shown in Figure 2 to reduce noise and

allow for proper drainage.

Make a hole(s) in the structure wall large enough to

accommodate the insulated vapor line, the liquid line and

the wiring.
