PREPARING FOR OPERATION

Every recovery procedure starts with the same six basics:
•
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.
•
Check the G5Twin to make sure it is operating normally by running the 1-Minute Bench Test on Page 18.
•
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-shuto " 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.
TANK COOLING METHOD (OPTIONAL)
Refrigerant temperature and pressure may increase during the
recovery process. In some conditions, additional steps taken to cool
the tank can increase the speed and e iciency of the recovery process.
The G5Twin is equipped with a high performance fan. You can use this
fan to provide additional tank cooling while you are performing the
recovery process.
Place the Recovery Cylinder behind the G5Twin during the recovery
process, as shown in Diagram 4. This will pull cool air across the tank
surface and lower the temperature of the tank.
