• • • CAUTION • • •
Only replace fasteners with exact replacements. Failure to do so could lead to fastener corrosion and/or failure.
1.12 General O-ring Handling
Various O-rings are utilized throughout the TTSeries Compressors to contain the refrigerant. Prior to the removal of
any component utilizing an O-ring, the refrigerant must be properly recovered per industry-standard procedures.
Upon O-ring replacement, a leak test should be performed. The following O-ring-specific steps are required when
replacing any compressor O-ring:
1. Remove each O-ring to be installed from its package and inspect for defects such as blemishes,
abrasions, cuts, or punctures.
2. Slight stretching of the O-ring when it is rolled inside out will help to reveal some defects not
otherwise visible.
3. After inspection and prior to installation, lubricate the O-ring with a light coat of Super-O-Lube.
4. Avoid rolling or twisting the O-ring when maneuvering it into place.
5. Keep the position of the O-ring mold line constant.
NOTE
It is strongly suggested that anytime an O-ring is removed, that a new O-ring is used in its place.
