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.
A. Preparing the Icemaker for Long Storage
WARNING
When shutting off the icemaker for an extended time, drain out all water from the
water tank and remove the ice from the storage bin. The storage bin should be
cleaned and dried. Drain the icemaker to prevent damage to the water supply
line at sub-freezing temperatures, using air or carbon dioxide. Shut off the
icemaker until the proper ambient temperature is resumed.
Note: When the icemaker is not used for two or three days, it is sufficient to only move
the control switch to the “OFF” position, unless the icemaker will be at
sub-freezing temperatures.
1) Remove the front panel.
2) Move the control switch on the control box to the “OFF” position.
3) Wait 3 minutes.
4) Move the control switch to the “ICE” position.
5) When all the ice from the previous ice making cycle has defrosted from the evaporator,
(approximately 2 minutes) close the potable water supply line shut-off valve and open
the line drain valve.
6) Use compressed air or carbon dioxide to blow any remaining water from the pipes.
7) Move the control switch to the “OFF” position.
8) Turn off the power supply.
9) Close the potable water drain valve.
10) Drain the water tank by removing the base
cover and one end of the pump tubing.
See Fig. 4.
11) Replace the removed parts in their correct
positions.
