VI. CLEANING AND MAINTENANCE INSTRUCTIONS

IMPORTANT

Ensure all components, fasteners and thumbscrews are securely in place after
any maintenance or cleaning is done to the equipment.

1.  PREPARING THE ICE DISPENSER FOR LONG STORAGE

IMPORTANT

When shutting off the ice dispenser for an extended time, drain out all water
from the water line and remove the ice from the Storage Bin.  The Storage Bin
should be cleaned and dried.  Drain the ice dispenser to prevent damage to the
water supply line at sub-freezing temperatures, using air or carbon dioxide.
Shut off the ice dispenser until the proper ambient temperature is resumed.

1) Close the Water Supply Line Shut-off Valve.

2) Move the Ice Making Switch, located on the left of the Middle Front Panel, to the “FLUSH”

position.

3) Move the Ice Switch, located on the right of the Middle Front Panel, to the “ON” position.  Move

the Water Switch to the “OFF” position.
