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.

Check Shipment — File claim with shipping company if shipment is damaged or incomplete.

Unit Location Considerations — Locate unit on floor in a well-ventilated area. Position unit to allow sufficient space for refrigerant and water connections and to service compressor. Place unit so suction and discharge valves can be easily reached and oil level checked. Do not install condensing unit where temperature will fall below freezing.

Local water can cause excessive fouling or sealing 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.

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

INSTALLATION

Mount Unit — Level unit and bolt firmly to foundation. Loosen compressor mounting bolts and remove shipping blocks from under compressor. Tighten all 4 bolts on compres- sor. Next, loosen each bolt until the flanged washer can be moved sideways with finger pressure.

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

Piping Connections — Attach water supply and return lines to connections indicated on condenser unit (Fig. 1). Water leaving condenser should not be connected directly into sewer lines. Check local codes.

Attach refrigerant liquid and suction lines to condensing units (Fig. 1); suction and discharge to compressor unit (Fig. 2). When soldering or brazing piping to valves, disassem- ble valve or wrap it in a wet cloth to prevent heat damage. Allow flexibility in suction line so compressor suction valve may be moved aside for access to suction strainer.

Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.
