How many access valves are needed to recover the refrigerant on a sealed system with an
operating compressor that has a completely restricted capillary tube? Two valves, one on
the high and one on the low side of the system
Self-contained or active recovery equipment; Has its own means of recovery
When using a system-dependent recovery system on an appliance that has a non-operating
compressor, the technician should; Run the compressor and recover from the high side of
the system
System-dependant devices may only be used on appliances containing; 15 lbs of
refrigerant
When filling a charging cylinder with a regulated refrigerant; The refrigerant vapor that is
vented off the top of the cylinder must be recovered
, If after installing a fitting for the purpose of recovering the appliances refrigerant, you find that
the system pressure is 0 psig; Recovery is not required
Applying heat with a heat gun to the compressor; can help vaporize any trapped liquid
refrigerant during recovery.

EPA section 608 rules require capture of 80% of the HCFCs and HFCs from small appliance
sealed systems with non operating. compressor if technicians are using; a system
dependent process
