Refrigerant replacement requirements
1. Non-contaminated refrigerant removed from any Follett refrigeration system can be recycled and returned to
the same system after completing repairs. Recycled refrigerant must be stored in a clean, approved storage
container. If additional refrigerant is required, virgin or reclaimed refrigerant that meets ARI standard 700-88
must be used.
2. In the event of system contamination (for example, a compressor burn out, refrigerant leak, presence of non-
condensibles or moisture), the system must be repaired, evacuated and recharged using virgin or reclaimed
refrigerant that meets ARI standard 700-88.
3. Follett Corporation does not approve of recovered refrigerants. Improper refrigeration servicing procedures
will void the factory warranty.
Evacuation
Evacuate the system to a level of 50 microns. When the 50 micron level is reached, shut the vacuum pump down.
Allow the system to sit for approximately 30 seconds. During this period the system should not rise above 1000
microns. If the system rises above 1000 microns, evacuate the system again. If the system rises above 1000
microns for a second time, check the system for leaks.
