I. LOCATE AND MOUNT THE UNIT
The condenser air discharges upward; therefore,
avoid locations where obstructions will deflect the hot
condenser discharge air back into the condenser inlet
air supply. In all cases, the condenser should be at
least 2 feet from any wall or obstruction and outside
of the plumb line from any overhang.
Use caution to prevent damage when moving the unit.
Use an adequate rope or cable sling and keep the unit
in an upright position at all times during rigging and
moving operations.
CAUTION: Protect the top and sides so that the
rigging sling will not damage the unit.
