This Service Manual has been written to cover product manufactured with HFC-134a.
Units previously manufactured with CFC-12 will, however, be in service for many years.
SERVICING CFC-12 SYSTEMS
U-Line Corporation has not approved the use of any "drop in" replacements for CFC-12.
U-Line has also not approved the process of converting a CFC-12 system to any other
type of refrigerant.
POTENTIAL PROBLEMS WITH HFC-134A
HFC-134A compressors will be received with a synthetic based ester oil charge. The
hygroscopic (water attraction) property of ester oil is many times greater than that of
the mineral oils previously used with CFC-12. High system moisture causes the forma-
tion of acids and alcohol which can damage the compressor. Systems should not be left
open for more than fifteen (15) minutes at any time as humidity from the air will enter
system. To assure system dehydration, the system should be pulled down to 100
microns and vacuum pump oil (mineral oil) must not be allowed to enter then system.
Cleanliness of the system will be extremely important. The presence of residues (chlori-
nated or greasy residues, mineral oil, or impurities) can lead to capillary tube restric-
tions, oil return problems and compressor damage. Flux must not be used on brazed
joints.
