Before installing, consider:
•
Locate the unit as close to the indoor sec-
tion as possible. (see page 11.)
•
S1CG/S2CG — If the unit is used for low
ambient cooling down to 32°F, S1CG/
S2CG require CCH.
•
Avoid high traffic areas and prevailing
wind locations.
•
Surface must be flat and level.
•
Mount unit above typical snow fall level.
This is particularly important for heat
pump applications (S1HG/S2HG).
NOTICE
•
Ensure free flow of air through the
unit.
•
Air must not recirculate from dis-
charge to intake — air is drawn
through the coil and side discharged
through the fan grille.
•
A minimum 48" clearance is neces-
sary for the condenser discharge.
•
Rear intake (coil side) clearance is
12" minimum.
•
Consider how power will be run to
the unit from the power source.
•
Refrigerant piping should be a direct
line to the indoor unit.
Site preparation
1.
Place the unit on a flat concrete surface
or pad if on the ground. Roof mounting
should use a build up platform to avoid
intake of hot air from the roof.

2.
In areas of heavy snowfall, condensers
should be set above the maximum antici-
pated snow line (12" is usually adequate
for most locations).
Unit Mounting Instructions
Model S1CG is shown for example in the
following sequence.
The side-discharge unit allows for permanent
mounting through the feet. This is highly
recommended due to the vertical design of
the unit.
