USE

(cont.)

Never keep anything in the ice storage bin that is not ice. Objects like
wine or beer bottles are not only unsanitary, but the labels can slip off
and plug up the drain.

Never allow the machine to operate without regular cleaning. The
machine will last longer if it is kept clean. Regular cleaning should
happen at least once per year, and preferably twice. Some water
conditions will dictate even more frequent cleaning of the ice making
section, and some carpets or pets will dictate more frequent cleaning
of the condenser.
Note: The Time to Clean light will switch ON after 6 months of use. It
will remain ON until the ice making system is cleaned using the process
in the “How to clean the condenser and winterize” section.

Noise
The ice machine is designed for quiet operation, but will make some
noise during the ice making cycle. During a freezing cycle, it is normal
to hear the fan moving air and the water pump circulating water. Ice
hitting the bin or ice in the bin can be heard during harvest. If ice
making noise is objectionable, an appliance grade timer can be added
to the power supply. Set the timer to turn the machine off at the time(s)
of day when the noise is most objectionable.

Normal cubes are tapered cylinders. If the cubes are ragged and mis-
shaped, mineral scale must be removed from the ice making system.

WATER QUALITY

All water, including potable water supplied by municipalities, contains
some impurities or minerals. Water absorbs impurities from the air as rain
and/or as it flows through the ground. Some of the impurities are solid
particles, these are known as suspended solids, and a fine particle filter
will remove them. Other impurities are chemically bonded to the water
molecules, and cannot be filtered out, these are called dissolved solids.

Ice made by this machine will have a lower mineral content than the
water it was made from. This is due to the method of making ice. Purer
water will freeze first in the ice making molds. The reason for this is that
anything dissolved in water lowers the water’s freezing temperature. This
concentrates most of the impurities in the ice machine water reservoir
where they may form hard deposits known as scale. The machine dilutes
the concentration of minerals by over-filling the reservoir during the
harvest cycle (with the excess water flowing down the drain). s. Between
2 and 4 pints of water flow into the unit each cycle. Between 1 and 3.5
pints of that rinses the reservoir and goes down the drain.

Some impurities will inevitably remain, and will stick to the parts in the
machine, and will cause malformed ice cubes. Eventually, built up
mineral scale can shorten machine life.

To keep the machine operating properly, these impurities or minerals
will have to be regularly dissolved by an acid cleaning, using Ice
Machine Scale Remover. Directions for this may be found in the section
under care and cleaning.
