SAFETY CONSIDERATIONS

Installing, starting up, and servicing this equipment can be hazardous due to system pressures, electrical components, and equipment location (roofs, elevated structures, etc.). Only trained, qualified installers and service mechanics should install, start up, and service this equipment.

When working on the equipment, observe precautions in the literature, tags, stickers and labels attached to the equipment, and other safety precautions that apply. Follow all safety codes. Wear safety glasses and work gloves. Use care when handling, rigging, and setting bulky equipment.

Electrical shock can cause personal injury and even death. Be sure power to equipment is shut off before installing or servicing this equipment. There may be more than one dis- connect. Tag disconnect(s) to alert others not to turn power on until work is completed.

INSTALLATION

Receive and Inspect Unit — Inspect shipment for damage. File claim with the shipping company if shipment is damaged or parts are missing.

Local water conditions can cause excessive fouling or pitting of condenser tubes. If such conditions are anticipated, a water treatment analysis is recommended. Refer to Carrier System Design Manual, Part 5, for general water conditioning information.

Place Unit in Position — Locate unit on floor in a well-ventilated area. Install unit where it will be warmer than conditioned area. Position it to allow sufficient space for refrig- erant and water connections and to service compressor. Allow space at one end of condenser for tube cleaning or replacement. Place unit so suction and discharge valves can be easily reached and so oil level can be checked.

Make provision in piping layout to drain and vent condenser if system is to be shut down in winter.

Level unit and bolt firmly to foundation.

Check Compressor Mounting — Loosen compres- sor mounting bolts and remove shipping blocks from under compressor. Tighten all 4 bolts on compressor. Loosen each bolt just enough until the flanged washer can be moved sideways with finger pressure. See Fig. 1.

NOTE: Be sure that compressor floats freely on mounting springs.
