Step 2 Ð Rig and Mount the Unit

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

RIGGING Ð These units are designed for overhead rigging only. For this purpose, the transverse base channels extend beyond the sides of the unit, with holes provided in the end plates to attach cables or hooks. Rig with top skid packaging assembly in place to prevent unit damage by the rigging cable. As further protection for the coil faces, plywood sheets can be placed against the sides of the unit, behind the cables. Run the cables to a central suspension point so that the angle from the horizontal is not less than 45 degrees. Raise and set the unit down carefully.

If it is necessary to roll the unit into position, mount the unit on longitudinal rails, using a minimum of 3 rollers. Ap- ply force to the rails, not the unit. If the 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 the unit.

Raise from above to lift unit from the rails or pad when unit is in ®nal position.

COMPRESSOR MOUNTING Ð As shipped, the compres- sor is held tightly in place by self-locking bolts. Before start- ing unit, loosen self-locking bolts until the snubber washer can be moved sideways with ®nger pres- sure. Do not remove shipping bolts. See Fig. 3.

Step 3 Ð Complete Refrigerant Piping Connections

IMPORTANT: A refrigerant receiver is not provided with the unit. Do not install a receiver.

SIZE REFRIGERANT LINES Ð Consider the length of piping required between outdoor unit and indoor unit (evaporator), the amount of liquid lift, and compressor oil return. See Tables 3, 4A, and 4B and also refer to Part 3 of Carrier System Design Manual for design details and line sizing. Refer to indoor installation instructions for addi- tional information.
