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.
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.
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.
