ICE MACHINE LOCATION AND PREPARATION (Cont.)
Utility and Operational Requirements
• This ice machine must be connected to a potable
water supply.
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.

first in the ice making molds. The reason for this is
that anything dissolved in water lowers the water's

impurities of 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). Water use
varies with air and water temperatures.
Some impurities will inevitably remain, and will stick
to the parts in the machine. This 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

be found in the Care and Cleaning section.
This machine can be supplied with Reverse Osmosis
water, but the water conductivity must be no less
than 10 microSiemens/cm. A reverse osmosis system
should include post treatment or blending to satisfy
the R.O. water's potential aggressiveness.

Because water softeners exchange one mineral
for another, softened water may not improve water
conditions when used with ice machines.

• Minimum water pressure: 30 psi
• Maximum water pressure: 120 psi
• Minimum water temperature: 40°F
• Maximum water temperature: 90°F.
This ice machine is designed to operate in a wide
range of air temperatures with a minimum air

of 100°F.
Although the machine will function within the listed
ranges, it works best at water temperatures between

and 80°F.
Operating a unit outside of the limits can cause
problems that are not covered by the warranty and, if
extreme, cause damage to the unit.

of it through the grill at the bottom front. The grille
must not be blocked by any covering door, or other
obstruction.
