SELF-CONTAINED RECOVERY/EVACUATION
1. Place the 'ICE/OFF/WASH' switch in the 'OFF' position.
2. Install manifold gauge set, charging cylinder/scale,
and recovery unit or two-stage vacuum pump.
3. Open high and low side on manifold gauge set.
4. 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 an electronic leak detector
after charging the ice machine.
Follow the Charging Procedures below.
CHARGING PROCEDURES
Important
The charge is critical on all Icetro ice machines. Use
a scale or a charging cylinder to ensure the proper
charge is installed.
1. Be sure the 'ICE/OFF/WASH' switch is in the 'OFF'
position.
2. Close the vacuum pump valve and the low side
manifold gauge valve.
3. Open the high side manifold gauge valve.
4. Open the charging cylinder and add the proper
refrigerant charge (shown on nameplate) through the
discharge service valve.
5. Let the system “settle” for 2 to 3 minutes.
6. Set the 'ICE/OFF/WASH' switch to the 'ON' position.
