CHARGING PROCEDURES
1. The ice machine must be off.
2. Close the vacuum pump valve and the low side
manifold gauge valve.
3. Open the refrigerant cylinder and add the proper
refrigerant charge (shown on nameplate) into the
system high side (receiver service valve and
discharge line shut-off valve).
4. If the high side does not take the entire charge,
close the high side on the manifold gauge set.
Start the ice machine and add the remaining
charge through valves on back of ice making
head, or through valves on suction filter.
5. Run the ice machine in the freeze cycle.
6. Close the receiver service valve in the ice
machine head section.
7. Disconnect the manifold gauge set from the liquid
line shut-off valve.
8. Open the high and low side valves on the
manifold gauge set. Any refrigerant in the lines
will be pulled into the low side of the system.
9. Allow the pressures to equalize while the ice
machine is in the freeze cycle.
10. Disconnect the manifold gauge set from the
suction line shut-off valve.
11. Install and torque all valve caps
NOTE: Check for refrigerant leaks after all valve caps
have been installed.
