EVACUATING AND CHARGING PROCEDURES
Before opening any refrigerant hose or component, read the information furnished in:
-
Refrigerant Operating Characteristics.
-
Discharging, Evacuating, Adding Oil and Charging Procedures.
Remove sealing caps from subassemblies before making connections for final assembly. Use a small amount of clean 525 viscosity refrigerant oil on all
tube and hose joints.
Use new seal (O-ring) dipped in the clean 525 viscosity refrigerant oil when assembling joints. The oil will aid in assembly and help provide a leak-proof
joint.
When tightening joints, use a second wrench to hold the stationary part of the connection.
Tighten all tubing connections (see accompanying figure). Insufficient or excessive torque can cause loose joints or deformed joint parts. Either
condition can cause leakage.
