II.RIG AND MOUNT THE UNIT

CAUTION: Be sure unit panels are securely in place prior to rigging.

A.Rigging

The unit is designed for overhead rigging. Refer to rigging label for preferred rigging method. Spreader bars are not re- quired 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 ®nal position.

After unit is in position, remove all shipping wrapping and top crating.

B. Mounting

The unit must be elevated to ensure drainage from basepan during sub-freezing conditions and to prevent or limit block- age of outdoor coil during snowfall. Consideration should be given to speci®c geographical areas when determining height of unit elevation.

C. 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 ®nger pressure. See Fig. 4.
