PREPARING FOR OPERATION
Every recovery procedure starts with the same five basics:
•
Remove any
access valve cores
from the AC/R System access fittings with a
Valve Core Removal Tool
;
•
Remove any
core depressors
from the
hose fittings
. Do not use “quick disconnect” or “auto-shutoff” hose
connections for refrigerant recovery, as this can bring the recovery to a halt. Use only ball valves for low-loss.
•
Use the shortest length of
3/8”-diameter hoses
possible on every connection.
Even with 1/4” fittings, the
larger hose diameter can deliver better performance during recovery.
•
Purge the hoses of
non-condensables
as you connect the hoses, as needed, using best practices to minimize
any refrigerant release (aka “de minimis”).
Excess non-condensables can cause tank overheating, and may
contaminate recovered refrigerant.
•
Connect the G5Twin to a
grounded power source
for the proper voltage of the machine (115v/230v). If using
an extension cord, follow the cord sizing guidelines on Page 4.
