Carrier 06E - Manual

Compressors and Condensing Units
Hermetic, Water-Cooled
PRELIMINARY CHECKS
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 condi­
tioning information.
PLACING THE UNIT
Locate unit on floor in a well ventilated area.
Install unit where it will be warmer than condi­
tioned area. Position it to allow sufficient space for
refrigerant and water connections and to seiwice
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 it firmly to foundation.
COMPRESSOR
Remove 4 self-locking bolts from compressor­
mounting springs, and reassemble them with
flanged washers and neoprene snubbers as shown in
Fig. 1. Flanged washers and neoprene snubbers are
shipped in a cloth bag tied to compressor. Tighten
all 4 bolts. Then, loosen each until the flanged
washer can be moved sidewise. Check compressor
to see that it floats freely on its mounting springs.»
PIPING CONNECTIONS
Attach water supply and return line to con­
nections indicated on condensing unit (Fig. 3).
Water leaving condenser should not be connected
directly into sewer lines; check local codes.
Attach refrigerant liquid and suction lines to
condensing unit (Fig 3),suction and discharge lines
to compressor unit (Fig. 2) Discharge line muffler
and check valve are factory supplied with 06E com­
pressor units Install the muffler as close to shutoff
valve as possible and install the check valve in the
discharge line close to the muffler, on the down­
stream side. When soldering or brazing piping to
valves, disassemble the valve or wrap it in wet cloth
to prevent damage by heat Allow flexibility in
