MAKE PIPING SWEAT CONNECTIONS — Remove plastic caps from liquid and suction service valves. Use refrigerant grade tubing. Service valves are closed from the factory and are ready for brazing. After wrapping the service valve with a wet cloth, the tubing set can be brazed to the service valve using ei- ther silver bearing or
NOTE: Unit is shipped with
Pass nitrogen or other inert gas through piping while braz- ing to prevent formation of copper oxide.
To avoid damage while brazing, service valves should be wrapped with a
When brazing tubing sets to the service valves, a brazing shield MUST be used to prevent damage to the painted unit surface.
PROVIDE SAFETY RELIEF — A fusible plug is located in unit suction line; do not cap this plug. If local code requires additional safety devices, install as directed.
