4. Clean flux from all brazed copper to steel connections with cold water and a wire brush.
TESTING SYSTEM FOR REFRIGERANT LEAKS
1. Connect Refrigeration Gauges and Manifold Set to both of the refrigeration system process lines.
2. Connect Refrigerant Charging Cylinder to the Refrigeration Gauges and Manifold Set, then pressurize the
refrigeration system to saturation with clean refrigerant of the type specified on the Unit serial plate.
3. Leak check the entire refrigeration system.
NOTE: If a leak is suspected but cannot be detected, tape a poly or heavy paper envelope over the
area to capture the gas. Wait 10 minutes then check the content of the envelope for refrigerant.
4. Disconnect the Refrigerant Charging Cylinder from the Refrigeration Gauges and Manifold Set.
CHARGING THE REFRIGERATION SYSTEM
!
WARNING:
Disconnect power to the unit before servicing. Follow all lock out/tag out procedures established by the user. Verify all
power is off to the unit before performing any work.
Failure to comply could result in serious injury, death or damage to the equipment.
1. Connect Refrigerant Recovery System to the Refrigeration Gauges and Manifold Set.
2. Reclaim the refrigerant from the refrigeration system, then disconnect the Refrigerant Recovery System from
the Refrigeration Gauges and Manifold Set.
3. Connect Vacuum Pump to the Refrigeration Gauges and Manifold Set.

11. Using a crimp tool, Pinch off suction process line tube twice starting from free end. Leave crimp tool applied to
inner pinch.
12. Cut suction process line tube approximately 1/2 inch from outer pinch and fill open end with copper brazing
alloy.
13. Remove crimp tool.
14. Repeat steps 11, 12 and 13 on discharge process line.
