Outlet connection tubing:
• Ice: 1/4" plastic hose
• Water: 5/16" plastic hose
4. Drain water from the supply line.
5. Remove the plastic nut(s) and water line(s) from
outlet side of the water solenoid valve.
6. Drain water from the line.
7. Connect compressed air onto the inlet fitting of the
water solenoid valve.
8. Apply AC power to the solenoid valve by forcing
the ice maker mold assembly through several har-
vest cycles. Note! Damage to the solenoid can occur
if AC power is applied for more than 20 seconds.
9. Remove the plastic cover from the mold assembly.
The bail arm must be in the down ("oN") position.

10. Start the harvest cycle with a flat blade screw driver
inserted into the center of the small gear.
11. Turn the gear counter clockwise, when the hold
switch closes, the mold assembly will continue to
operate through the harvest cycle. During the water
fill sequence of the harvest cycle the compressed
air will blow out the water trapped in the solenoid
valve. Up to 20 PSIG air pressure can be used to
clear the solenoid valve.
12. Repeat the harvest cycle operation several times.
13. RefRIGeRaTOR wITh ICe & waTeR DISPeNSeR:
-
Clear the water part of the solenoid valve.
-
Press the lever to open the valve and then, apply
compressed air to blow out the water trapped in
this part of the valve.
Ice Dispenser
-
Blow out the water from the water dispenser hose.
14. Reconnect and tighten the lines on water solenoid
valve. Make sure that the metal tube is in the plastic
water line to the ice maker.
15. Leave the water supply turned off until temperatures
are above 32°f/0°C.
16. Dry the ice maker mold assembly with a soft cloth.
17. Place bail arm in the "UP/Off" position.
