ICE MACHINE LOCATION AND PREPARATION (Cont)
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
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. 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. 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 dissolved by an acid
cleaner. Directions for this may be found in the Care and
Cleaning section.
Installation Instructions
Filters and Treatment
In general, it is always a good idea to filter the water. A
proper water filter can remove taste and odors as well as
particles. We recommend using a GE Appliances Water
Filter on your water inlet line such as GE Appliances
Model Number GXRLQ. Please go to www.geappliances.
com to review the installation instructions and determine
which filter will suit your application. In Canada visit
www.GEAppliances.ca. Some other methods of water
treatment for dissolved solids include reverse osmosis, and
polyphosphate feeders.
RO Water
This machine can be supplied with Reverse Osmosis
water, but the water conductivity must be no less than
10 microSiements/cm. A reverse osmosis system should
include post treatment to satisfy the R.O. water's potential
aggressiveness. Deionized water is not recommended.
Because water softeners exchange one mineral for
another, softened water may not improve water conditions
when used with ice machines. Where water is very hard,
softened water could result in white, mushy cubes that
stick together.
If in doubt about the water, contact a local point of use
water specialist for recommendations on water treatment.
Installation Overview
The ice machine must:
- be connected to cold, potable water
- be connected to a drain
- be connected to the proper power supply
- be able to circulate air through the vents at the front
NOTE: Do not build in so that the door is recessed.
