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 LLC does not approve of recovered refrigerants. Improper refrigeration servicing procedures will void
the factory warranty.
Evacuation
Evacuate the system to a level of 500 microns. When the 500 micron level is reached, close all valves. Allow the
system to sit for approximately 20 minutes. During this period the system pressure should not rise. If the system
pressure rises and stabilizes there is moisture in the system and further evacuation is needed. If the pressure
continues to rise check the system for leaks.
