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.

Factory wiring is in compliance with National Electrical Code.
Field wiring must comply with appiicable local codes Maximum
wire size to control center line terminal block is 250 MCM.
Where compressor FLA is under 100 amps, wire sizes are based
on type TW wire. Where compressor FLA is over 100 amps, wire
sizes are based on type TFIW wire
Maximum wire lengths tabulated will result in a 1% voltage drop
to compressor A 3% voltage drop is maximum allowed.Therefore,
the run length can be increased to three times the value given.

ment are shown on diagram attached to unit (or in
wiring diagram booklet).
Discharge line limit thermostat supplied with
06EV,W compressor units is installed on discharge
hne as close to compressor as possible.

plate on discharge line and
solder in place.
2. Fasten the thermostat
to plate with screws
supplied.
3. Cover switch with insulation and secure insula

REFRIGERANT CHARGING
Evacuate, ' Dehydrate and Leak Test the entire
refrigerant system by methods described in Carrier
Standard Service Techniques Manual, Chapter 1,
Sections 1-6 and 1-7. Use sight glass method to
charge system. See section 1-8 of Service Tech
niques Manual for details.
CHARGE THE SYSTEM to a clear sight glass while
holding saturated condensing pressure constant at
125 F (air-cooled systems) or 105 F (water-cooled
systems). Add additional refrigerant to fill con
denser subcooler coils.
07E Condensing Units
obtained.
add charge
After clear sight glass is
until liquid refrigerant
reaches condenser liquid level test cock.
06E Compressor Units — See condenser data for
additional charge required to fill subcooler.
INITIAL START-UP
Crankcase heater should be energized a mini
mum of 24 hours before starting unit.
Check to see that oil level is 1/3 to 2/3 up on
compressor sight glass.
Open water supply valve and allow water to
reach condenser. (Turn condenser fan on when the
compressor unit is applied with air-cooled
condenser.)
Backseat the compressor suction and discharge
shutoff valves; open liquid line valve at receiver.
Start evaporator fan or chilled water pump.
To Start Compressor, place control center start-
stop switch in “Start” position, and push motor
protector relay start-reset button. (Time Guard
circuit will cause a short delay before compressor
starts.) If compressor does not start in a 5-minute
period, reset oil pressure safety switch and over
load relays.
Recheck oil level and check oil pressure which
should be 12-18 psig above suction pressure.
NOTE: If compressor is shut off by motor
protection relay, current overloads, oil safety
switch or if control circuit power is opened, reset
button(s) must be pushed before compressor will
restart. Do not reset safety controls more than
once before determining cause of shutdown.
CHECKING OPERATIONS
Refer to Carrier Standard Service Techniques
Manual, Chapter 2 for complete instructions on
checking electrical components.
Oil Pressure Safety Switch (Fig. 6 and 7) may be
checked by moving arm on left side of switch
forward. Compressor should stop in approximately
45 seconds. (If compressor continues to run, check
wiring to safety switch. If wiring is correct, the
switch is faulty and should be replaced.)
After completing test, press reset button on
front of safety switch and restart compressor.
(Allow 3 minutes before attempting to reset
switch.)
NOTE Check oil level in compressor sight glass
after 15-20 minutes of operation. If oil level is low,
add oil according to methods described in Carrier
Standard Service Techniques Manual, Chapter 1
(Section 1-11).
