compressor failures caused by flooded start, floodback, and
running out of oil.
The Troubleshooting Procedures section (Section 2.3,
pages 20 to 31) will help pinpoint compressor and system
problems.
The Service Procedures section (Section 2.4, pages 32 to 43)
covers the replacement of valve plates and gaskets, service
to the bearing head assembly containing the oil pump, and
a
clean-up procedure to follow in case of motor burnout. Most
other internal service requires replacement of the compres-
sor.
2.2 — Recommended Start-Up Procedure
Reliability data of Carlyle’s 06D, 06E, and 06CC refrigera-
tion compressors indicate that at least half of compressor
failures occur during the first two to four months of opera-
tion. Many of these failures occur during the initial start-up
of the unit. In other cases, troubled start-ups lead to com-
pressor damage severe enough to cause premature failures.
The major causes of failures of these compressors are
flooded start, floodback, and running out of oil. Most of
these failures can be avoided by using more care during the
initial start-up of the compressors. Therefore, the following
start-up procedure for 06D, 06E and 06CC compressors is
provided.
BEFORE START-UP
1. Verify that the compressor nameplate indicates proper
model and voltage. Do the values agree with system
needs and available power?
2. Verify that there is oil in the system.
Since different refrigerants (CFC, HCFC or HFC) require
specific oils (mineral, alkylbenzene, or polyolester [POE]),
