13.10 Compressor
13.10.1Compressor Oil
NOTICE
Risk of improper compressor lubrication. Can cause compressor and refrigerant system
damage.
Failure to use oil types, viscosities and quantities recommended by the compressor
manufacturer may reduce compressor life and void the compressor warranty. See oil types
specified in Table 62.
• Do NOT mix polyolester (POE) and mineral-based oils.
• Do NOT mix oils of different viscosities.
Consult Emerson or the compressor manufacturer if you have questions.
1. Use Carlyle POE Oil Totaline P903-1001, Castrol SW68 or other Carlyle-approved oils.
2. Use Copeland POE Oil ULTRA 32-3MAF or other Copeland-approved oils.
13.10.2Semi-Hermetic Compressors
Oil level can be viewed at the sight glass on semi-hermetic compressors. Normal operating oil level is
1/4 to 3/4 up the sight glass.
After a compressor has been idle for an extended length of time, foaming will usually be present when
compressor first starts. Wait until compressor has been operating for at least five minutes before
viewing the oil level.
If oil level is low, the cause must be corrected and oil level returned to its proper level.
13.10.3Scroll and Digital Scroll Compressors
Hermetic scroll and digital scroll compressors do not have an oil sight glass.
13.11 Compressor Replacement
Replacement compressors are available through your local Emerson office. Compressors are shipped
in reusable packaging. If unit is under warranty, complete and include Liebert Service Credit
Application (LSCA) with the compressor that is being returned. The original compressor should be
returned in the same packaging.
13.11.1Compressor Motor Burnout
If a burnout has occurred, a full system clean-out is required; if not, compressor and system problems
will continue.
For clean-out warnings and procedures, see Copeland Application Engineering Bulletin 24-1105
“Principles of Cleaning Refrigeration Systems” or Carlyle Service Guide, Literature # 020-611.
