REFRIGERANT RECOVERY
1. Attach the manifold gauges and the
refrigerant recovery unit to the refrigerant
lines as shown.
NOTE:
Be careful not to switch the
connections for the low and
high pressure valves.
2. Open the high pressure valve slowly to release the refrigerant to the recovery unit.
NOTE:
Open the valve slowly, while checking to see that refrigerant is not leaking out.
3. When the manifold gauge dial falls below 3.5 kg/cm
2
(50 psi), slowly open the low pressure valve.
4. Open both the high and low pressure valves slowly until the manifold gauge dials indicates 0 kg/cm
2
(0 psi).
VACUUMING REFRIGERANT SYSTEM
1. Vacuuming Procedure.
NOTE:
When the A/C system has been
exposed to the air, it must be
vacuumed out. Perform vacuum
process for 30 minutes for
complete moisture and air
evacuation.
A. Attach the manifold gauges and vacuum pump to the refrigerant system as shown.
B. Turn on the vacuum pump and open both valves.
C. When the low pressure gauge shows approximately 710 mmHg, close both valves and turn off
vacuum pump.
