PRE-START-UP
Evacuate, Dehydrate, and Leak Test —
The entire
refrigerant system must be evacuated, dehydrated and leak test-
ed by methods described in Carrier Standard Service Tech-
niques Manual, Chapter 1, Section 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 condenser subcooler coils for air-cooled
applications.
Oil Charge (See Tables 2 and 3) —
All units are
factory charged with oil. If oil is visible in sight glass, start
compressor. Observe level and add oil, if required, to bring
level in crankcase

of bull’s-eye during steady
operation. To add or remove oil, see Carrier Standard Service
Techniques Manual, Chapter 1, Refrigerants.

*Approved for R-12, R-22, R-502 refrigerants. Contact Carrier
Factory Sales Representative for other refrigerants.
TO ADD OIL — Close suction shutoff valve and pump down
crankcase to 2 psig. (Low-pressure cut-out must be bypassed.)
Wait a few minutes and repeat as needed until pressure remains
at 2 psig. Remove oil fill plug above bull’s-eye, add oil through
plug hole and replace plug. Run compressor for about 20 min-
utes and check the oil level.
TO REMOVE OIL — Pump down compressor to 2 psig.
Loosen the

-in. pipe plug in compressor base and allow the
oil to seep out past the threads of the plug. The crankcase will
be under slight pressure. Be careful not to remove the plug; the
entire oil charge may be lost.

*Compressors listed are for R-22 applications. For R-134a an 06EM compressor
is standard offering; an 06ER compressor is standard for R-507/404A. Factory
compressor substitutes may be made. Contact Carrier Sales Representative.
When charging, or when removing charge, circulate water
through water-cooled condenser and cooler continuously to
prevent freezing. Freezing damage is considered abuse and
is not covered by Carrier warranty.
IMPORTANT: Use only Carrier approved compressor oil.
Do not reuse oil that has been drained and do not use oil
that has been exposed to atmosphere.
