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 500 microns. When the 500 micron level is reached, close valves and both
manifold and shut down the vacuum pump. 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.

Refrigeration system
Important: All service on refrigeration system must be performed in accordance with all federal, state and
local laws that pertain to the use of refrigerants. It is the responsibility of the technician to ensure that these
requirements are met.
Recharging of unit at other than factory specifications will void icemaker
warranty.
