PRELIMINARY SURVEY

Inspect shipment for damage. File claim with

the shipping company if shipment is damaged or

incomplete.

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 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.

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.

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.

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 connec

tions 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 supplied with 06EV,W compressor units is

installed in discharge line as close to shutoff valve

as possible. When soldering or brazing piping to

valves, disassemble the valve or wrap it in wet cloth

to prevent damage by heat. Allow flexibility in

suction line so compressor suction valve may be

moved aside for access to suction strainer.

Install a solenoid valve (field supplied) in liquid

hne directly before expansion valve. Solenoid valve

is necessary for single pumpout control used on

06E,07E units (refer to Start-Up and Service

Instructions). A filter-drier of adequate size should

be installed in liquid line between condenser and

solenoid valve.

Pressure relief valve located on side of con

denser will open to relieve excessive pressure,

allowing refrigerant to escape. Most local codes

require piping from valve to outdoors.

Refer to Carrier System Design Manual for

standard piping techniques.

* Pressures noted are above operating suction pressure; i.e , pressure

differential between suction pressure and discharge pressure of oil

pump.

Î Pressure switch settings shown are for R-22. When using other

refrigerants, reset high- and low-pressure switch settings to

pressures corresponding to satuialion temperatures indicated by

the above pressures.
