USER GUIDE
R-600A Specications
Evacuate/reclaim via the piecing pliers to ensure the
system is empty of R-600a before any system work is
performed.
The recovery cylinder must be evacuated (no air inside)
prior to accepting R-600a.
The recovery cylinder must not be filled more than 45%
safe fill level and refrigerants must not be mixed.
The recovery cylinder must be clearly marked with R-
600a and Flammable Warning labels.
Ensure proper ventilation during recovery/reclaiming of R-
600a.
Start vacuum pump/recovery pump prior to piercing the
compressor process tube.
Follow recovery/reclaim OEM instructions for the specific
equipment used.
SYSTEM REPAIR
Ensure no residual R-600a refrigerant is left within the
system prior to repair (simple venting is not sufficient).
Evacuate and charge with dry nitrogen for leak checks.
Repair leaks or replace system parts as required.
When re-brazing, the system must be purged with dry
nitrogen and at least one access point open to the
atmosphere.
When re-brazing, proper ventilation is required along with
constant monitoring for the presence of R600a refrigerant.
The filter dryer must be replaced any time the sealed
system is serviced.
No system should be open to the atmosphere for longer
than 15 minutes to avoid moisture migration into the
system components.
LEAK DETECTION
After removal of the R-600a, the unit can be charged with
dry nitrogen or helium.
Electronic leak detection or soap solution can be used to
check for nitrogen/helium leaks.
Never use a halide torch or lighted match to check the
system for leaks at any time.
The high side of the refrigeration system (compressor
discharge to outlet of drier) must be leak tested with the
compressor running.
Evacuate/reclaim via the piecing pliers to ensure the
system is empty of R290/R600a before any system work is
performed.
The recovery cylinder must be evacuated (no air inside)
prior to accepting R290/R600a.
The recovery cylinder must not be lled more than 45%
safe ll level and refrigerants must not be mixed.
The recovery cylinder must be clearly marked with R290/
R600a and Flammable Warning labels.
Ensure proper ventilation during recovery/reclaiming of
R290/R600a.

compressor process tube.
Follow recovery/reclaim OEM instructions for the specic
equipment used.
