• Allow sufficient space for airflow clearance, wiring, refrigerant piping, and unit servicing. See Fig. 2. • Locate unit so that condenser 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 Table 2 for weight distribution based on recommended support points. NOTE: If vibration isolators are required for a particular installation, use corner weight information in Table 2 to make proper selection.

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 materials and top crating. COMPRESSOR MOUNTING — Compressors are shipped from the factory held down by 4 bolts. After unit is installed, loosen each bolt until the snubber washer can be moved with finger pressure. See Fig. 4. Step 3 — Complete Refrigerant Piping Connections — Suction connection is sweat with plastic cap; liquid connection is sweat with plastic cap. Refer to Table 3A or 3B for the proper line sizes. Follow standard piping practices. SIZE REFRIGERANT LINES — Consider length of piping required between condensing unit and air handler, amount of liquid lift, and compressor oil return. See Table 4A and 4B and also refer to Part 3 of Carrier System Design Manual for design details and line sizing. Refer to air handler installation instructions for additional information.

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 rigging. 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 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, UNIT 38 0-25 (0-7.6) 25-50 (7.6-15.2) 50-75 (15.2-22.9) 75-100 (22.9-30.5) Line Size (in.
