While brazing refrigerant pipes, continuously purge them with nitrogen gas. Use a pressure
regulator to maintain a fl ow rate of 1.76 ft³/h (0.05 m³/h) or more.
Nitrogen Purging While Brazing
NOTICE
Avoid Unit Damage!
Never braze pipe connections without performing nitrogen purging. Failure to perform this
procedure will damage the unit, resulting in capacity loss and reduced long-term reliability.
Refrigerant Piping Precautions
NOTICE
System Component Damage!
Do not remove the seal caps from the refrigerant connections and piping until prepared to braze
refrigerant pipes to the connections. Excessive exposure to atmosphere (greater than 5 minutes)
may allow moisture or other particulates to contaminate the system, damaging valve seals and
causing ice formation in the system components during operation.
