Mounting the Unit
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  at and level.•
Mount unit above typical snow fall level. •
This is particularly important for heat
pump applications (S1HG/S2HG).
NOTICE
Ensure free  ow 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
Place the unit on a  at concrete surface 1.
or pad if on the ground. Roof mounting
should use a built up platform to avoid
intake of hot air from the roof.
In areas of heavy snowfall, condensers 2.
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.
 e side-discharge unit allows for permanent
mounting through the feet. This is highly
recommended due to the vertical design of
the unit.
1. Figure 1, Page 7 :
Bullet 1 — Loosen the screws on le –
and right sides of the front panel. (Do
not remove these screws.)
Bullet 2 — Remove the screws on the –
front of the panel.
2. Figure 2, Page 7 :
Slide front panel forward to clear side
screws and remove.
3. Figure 3, Page 7 :
Insert lag bolts through the holes in the
bo om of the unit and tighten to secure.
4. Figure 4, Page 7 :
Insert lag bolts through the holes in the
feet on the back of the unit and tighten
