CONSIDER SYSTEM REQUIREMENTS
• Consult local building codes and NEC (U.S.A.) for spe-
cial installation requirements.
• Allow sufficient space for airflow clearance, wiring, re-
frigerant piping, and servicing unit. See Fig. 2.
• Locate unit so that outdoor unit airflow is unrestricted on
all sides and above. Refer to Fig. 2.
• Unit may be mounted on a level pad directly on base rails
or mounted on raised pads at support points. See Fig. 2 for
weight distribution based on recommended support points.
• Provide for condensate drainage and defrost water dis-
posal beneath unit.
• Areas with high snowfall may need elevated mounting for
adequate airflow.
NOTE: If vibration isolators are required for a particular in-
stallation, use corner weight information in Fig. 2 to make
proper selection.
Step 2 — Rig and Mount the Unit
Be sure unit panels are securely in place prior to

rigging.

RIGGING — These units are designed for overhead rig-
ging. Refer to rigging label for preferred rigging method.
Spreader bars are not required if top crating is left on unit.
All panels must be in place when rigging. (See Fig. 3.) As

further protection for coil faces, plywood sheets may be placed
against sides of unit, behind cables. Run cables to a central
suspension point so that angle from the horizontal plane is
not less than 45 degrees. Raise and set unit down carefully.
If it is necessary to roll unit into position, mount unit on
rails, using a minimum of 3 rollers. Apply force to rails, not
unit. If unit is to be skidded into position, place it on a large
pad and drag it by the pad. Do not apply any force to unit.
Raise from above to lift unit from rails or pad when unit
is in final position.
After unit is in position, remove all shipping wrapping and
top crating.
MOUNTING — The unit must be elevated to ensure drain-
age from basepan during sub-freezing conditions and to pre-
vent or limit blockage of outdoor coil during snowfall. Con-
sideration should be given to specific geographical areas when
determining height of unit elevation.
COMPRESSOR MOUNTING — As shipped, compressors
are held down by 4 bolts. After unit is installed, loosen each
bolt until the snubber washer can be moved with finger pres-
sure. See Fig. 4.
Step 3 — Complete Refrigerant Piping Connec-
tions —
Suction connection is sweat with plastic cap; liq-
uid connection is sweat with plastic cap. Refer to Table 2 for
the proper line sizes. Follow standard piping practices.
