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 wait until the freeze cycle starts, then
add the remaining charge through valves on back of
ice making head, or through valves on suction filter.
5. Disconnect the manifold gauge set from the liquid line
shut-off valve.
6. 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.
7. Allow the pressures to equalize while the ice machine
is in the freeze cycle.
8. Disconnect the manifold gauge set from the suction
line shut-off valve.
9. Install and torque all valve caps
NOTE: Check for refrigerant leaks after all valve caps have
been installed.
