R22 Refrigerant System Servicing Continued.
Figure 3-6. R22 Refrigerant System Servicing (Sheet 9 of 10)
Turn compressor service discharge valve (14) clockwise to the full closed (front seated) position.
Shut off ECV engine.
Condenser and receiver are still at full pressure. R22 refrigeration system must be recovered
before removing condenser or receiver. Failure to do so will cause injury to personnel or
damage to equipment.
The majority of the R22 refrigerant is now stored, in liquid form, in the receiver. Components
in the R22 refrigeration system can now be removed, except for the receiver and condenser. The R22
refrigerant must be completely recovered before the receiver or condenser are removed.
