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 any other safety precautions that apply. Follow all safety
codes. Wear safety glasses and work gloves. Use care in
handling, rigging and setting bulky equipment.
BEFORE INSTALLATION
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.
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
disconnect. Tag disconnect(s) to alert others not to turn
power on until work is completed.
