NOTICE
Before handling aluminum coil components, clean your hands after handling the copper lines set or other tubing.
6. Refrigerant Line Connection
Coil is under inert gas pressure. Relieve pressure from coil by depressing Schrader core at the end of the
suction-manifold stub out.
Always supply dry nitrogen through the tubing while it is being brazed. Unless an inert atmosphere is provided,
the temperature required is high enough to cause oxidation of the copper. Continue the À ow of dry nitrogen
until the joint has cooled. Always use a pressure regulator and safety valve to insure that only low pressure
dry nitrogen is introduced into the tubing. Only a small À ow is necessary to displace air and prevent oxidation.
