Remote Charging Procedures
1. Close the vacuum pump valve and the low side
manifold gauge valve.
2. Open the refrigerant cylinder and add the proper
refrigerant charge (shown on nameplate) into the
system high side (receiver outlet valve and discharge
lines quick-connect fitting).
3. If the high side does not take the entire charge, close
the high side on the manifold gauge set and start the
ice machine. Add the remaining refrigerant through
the low side until the machine is fully charged.
NOTE: If an access valve core removal and installation
tool is used on any of the Schrader valves, reinstall the
cores before disconnecting the access tool and hose.
4. Remove the high side low loss fitting from the access
valve.
5. 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.
6. Allow the pressures to equalize while the ice
machine is in the freeze cycle.
7. Remove the low side hose from the access valve and
install the caps.
NOTE: Check for leaks with an electronic leak
detector after charging the ice machine.
