2. Close the vacuum pump valve and the low side
manifold gauge valve.
3. Open the high side manifold gauge valve.
4. Open the refrigerant cylinder and add the proper
refrigerant charge (shown on nameplate) through
the discharge service valve.
5. Close the high side on the manifold gauge set.
Add any remaining vapor charge through the
suction access fitting (if necessary).
6. Let the system “settle” for 2 to 3 minutes.
7. Place the toggle switch in the ICE position.
NOTE: Manifold gauges must be removed properly to
ensure that no refrigerant contamination or loss
occurs.
8. Make sure that all of the vapor in the charging
hoses is drawn into the ice machine before
disconnecting the charging hoses.
A. Run the ice machine in the freeze cycle.
B. Verify the refrigerant cylinder valve is closed.

machine is in the freeze cycle.
E. Close the high and low side manifold gauge
set.
F. Remove the hoses from the ice machine and
