Service Manual
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 ows through the ground. Some of
the impurities are solid particles, these are known
as suspended solids, and a ne particle lter will
remove them. Other impurities are chemically
bonded to the water molecules, and cannot be
ltered 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 rst 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-lling
the reservoir during the harvest cycle (with the
excess water owing down the drain). s. Between
2 and 4 pints of water ow 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 Scotsman Ice
Machine Scale Remover. Directions for this may be
found in the section under cleaning.
Filters and Treatment
In general, it is always a good idea to lter the
water. A water lter, if it is of the proper type, can
remove taste and odors as well as particles. Some
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 microSiemens/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 circulate air through the vents at the
front.
Note: Do not build in so that the door is recessed.

Service Manual
Door Panel
The ice machine is supplied without a conventional
door covering so it can be decorated to the user’s
preference. Scotsman offers several coverings
including white, black and stainless steel. In
addition, a custom built panel can be placed onto
the door.
Door Panel Attachment
To attach a Scotsman supplied panel:
Note: If door swing is to be changed, it must be
done before panel is attached.
The panel will be held on by 6 sheet metal screws
and 2 machine screws.
1. Remove the gasket and retain for later use.
2. If the door panel is stainless steel, remove any
plastic covering the stainless steel panel.
Custom Panel
A custom panel of wood or other material not
exceeding 15 lb can be attached to the door.
Attachment is from the ice side of the door. Holes
are provided in the door for this purpose.
See instructions in information packet to create and
attach a custom panel:
3. Place the panel onto the outside of the door,
and secure it to the door using two machine
screws, located at the left center and right center.
4. Fasten the panel to the door using the 6 sheet
metal screws. In the hinge area, use the outermost
screw holes.
5. Place the covers over the hinge areas, and
secure each cover to the door using a sheet metal
screw.

space (from bottom of door to oor).
This could be equal to the adjacent
cabinet’s kickplate space or another
space the user wants.
3. Subtract kickplate space from
cabinet opening.
10. Mount panel to door using wood screws or
supplied panel mounting screws.
Note: When installed Ice machine must be

Installation Notes
Built In Situations: If a nished oor is to be
installed in the area after the ice machine has
been built in, shims the expected thickness of the
oor should be installed under the unit to keep the
machine level with the planned oor level.
Installations on a slab: Use a pump model and
pump the water to the point of drainage. Pump
models will pump 1 story (10 feet) high.
Installations over a crawl space or basement:
Either gravity drain or pump model units may
be used, if there is not enough room behind the
machine for a drain/waste receptacle, the drain will
have to be below the oor.
Note: When installed in a corner, the door swing
may be limited due to handle contact with the wall
or cabinet face.
