Recovery of Refrigerant

AIR CONDITIONING SYSTEM SERVICE

INSTALLATION OF MANIFOLD GAUGE SET
R-134a system employs new high and low service charge ports with "quick connect" adapters. Each adapter is a female fitting with threads on the inside to protect the system from contaminations. This type of change port is also expected to reduce refrigerant leakage.












1. Close both hand valves of manifold gauge set.
2. Install charging hoses of gauge set to service ports. Connect the low pressure hose to the low pressure service port in the suction pipe and the high pressure hose to the high pressure service port in the discharge hose.

RECOVERY OF REFRIGERANT
Use only service equipment that is U.L.-listed and is certified to meet the requirements of SAE J2210 to remove HFC-134a (R-134a) from the air conditioning system.

1. Connect a R-134a refrigerant Recovery/Recycling/Charging System to the vehicle, following the equipment manufacturer's instructions.

2. Measure the amount of refrigerant oil removed from the A/C system after the recovery process is completed.

NOTE: Be sure to install the same amount of new refrigerant oil back into the A/C system before charging.
