Place the toggle switch in the OFF position.
Install manifold gauges (with low loss fittings), scale,
and recovery unit or two-stage vacuum pump.
Open (backseat) the high and low side on manifold
gauges.
Perform recovery or evacuation:
A. Recovery: Operate the recovery unit as directed by
the manufacturer’s instructions.
B. Evacuation prior to recharging: Pull the system
down to 500 microns. Then, allow the pump to run
for an additional half hour. Turn off the pump and
perform a standing vacuum leak check.
NOTE: Check for leaks using a halide or electronic
leak detector after charging the ice machine.
