Refrigeration System Section 7

Remote Charging Procedures (QF2200/QF2300)
1. Be sure the toggle switch is in the OFF position.
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 quick-connect fitting).
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 the suction filter low side service port.
Compressor damage can result.
5. Ensure all vapor in charging hoses is drawn into the
low side of the system, then disconnect the manifold
gauges.
6. Run the ice machine in freeze cycle.
7. Close the receiver service valve in the ice machine
head section.
8. Disconnect the manifold gauge set from the liquid
line shut-off valve.
9. 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.
10. Allow the pressures to equalize while the ice
machine is in the freeze cycle.
11. Disconnect the manifold gauge set from the suction
line shut-off valve.
12. Remove the hoses from the ice machine and install
the caps.
NOTE: Check for refrigerant leaks after all valve caps
have been installed.
