NOTE

A very strong acid (HCL) is formed when R-12 comes in contact with
moisture.

A new receiver-dehydrator should be opened and connected to the system
only when ready to charge the system with refrigerant.

9. Recommended torque values must be used on all flare fitting and O-ring joints. See Table XIV-II.

14-6. SERVICE VALVES. The purpose of the service valve is to service the air conditioning system (Testing,
Bleeding, Evacuating and Charging). This aircraft is equipped with service valves mounted in the suction and
discharge lines of the evaporator assembly. These valves are the “2” position type Schrader valves. All normal
air conditioning service should be performed at the evaporator assembly mounted valves.

NOTE

Service valves are also located on the compressor. However, use of these
valves in servicing is not recommended.

NOTE

If a Schrader service valve is not serviceable, the core assembly must be
replaced.
