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. Apply force to the rails, not the unit. If the unit is to be skid- ded 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 pressure. 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 pip- ing required between outdoor unit and indoor unit (evapo- rator), the amount of liquid lift, and compressor oil return. See Tables 3-5B and also refer to Part 3 of Carrier System Design Manual and E20-II software for design details and line sizing. Refer to indoor unit installation instructions for additional information.

NOTE: Use the piping data in Tables 3-5B as a general guide only. For more precise calculations, refer to Carrier System Design manual or E20-II software.

Condensing units with multiple-step unloading may require double suction risers to assure proper oil return at minimum load operating condition. See Tables 4A-5B and Fig. 4. Reduction of evaporator coil surface should be ana- lyzed to provide sufficient refrigerant velocity to return oil to the compressor. Liquid line solenoid valves may be used in certain situations to accomplish this. Hot gas bypass, if used, should be introduced before the evaporator.

Note that refrigerant suction piping should be insulated.
