RECHARGING
No air is ever to be allowed inside the refrigeration system
(R-600a refrigerant or dry nitrogen only).
Never use a torch on a fully charged refrigeration system.
Install a Schrader Type access port on the compressor
process stub.
Evacuate the system to 100 microns prior to charging.
Weigh in the R-600a charge using a refrigerant scale. (run
compressor an extra two minutes to clear the charging
hoses).
Seal the Schrader Type access port, a proper cap and seal
must be used to close the system.
