Transfer Refrigerant from Storage Tank to Machine

1.Equalize refrigerant pressure.

a.Use the Control Test Terminate Lockout to turn on water pumps and monitor pressures.

b.Close pumpout/storage tank valves 2, 4, 5, and 8, and close machine charging valve 7; open machine isolation valves 11, 12, 13, and 14 (if present).

c.Open pumpout/storage tank valves 3 and 6, open machine valves 1a and 1b.
