Service Manual
This ice machine is designed to be used indoors, in
a controlled environment. It can be used in a wide
variety of environmental conditions, but there are
limits. Use outside of the listed limitations is misuse
and will void the warranty.
Air temperature limits:
The ice machine will operate adequately within the
limits, but functions best in temperatures between
70 and 80 degrees F.
Minimum – 50 degrees F. (10oC)
•
Maximum – 100 degrees F. (38oC)
•
Water temperature limits:
Minimum – 40 degrees F. (4.5oC)
•
Maximum – 100 degrees F. (38oC)
•
Water pressure limits:
Minimum – 20 psi (1.4 bar)
•
Maximum – 80 psi (5.5 bar)
•
Because the ice machine is making a food product,
the water supply to the ice machine must be
potable, or fit for human consumption.
Options:
Door Panel kits:
Finished door panels are available from Scotsman
for attachment to the machine, or a custom panel
can be made.
Kit Number Panel Finish Handle Finish
KDFS Stainless Steel Stainless Steel

A gravity drain model can be converted to a drain
pump model by installing a drain pump kit. The
drain pump kit consists of a drain pump, wiring
harness and associated tubing. The kit number is
A39462-021.

Air flow
The machine takes in room temperature air at the
lower right front and forces warm air out the lower
left front. Restricting the airflow will adversely affect
the ability of the ice machine to make ice.

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 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.
Filters and Treatment
In general, it is always a good idea to filter the
water. A water filter, 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. 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:
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.

Note: Do not build in so that the door is recessed.
Door Covering

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.
6. Insert hole plug over screw installed in step 5.
7. Return the gasket to its original position.

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.
To create and attach a custom panel:
Panel width: 14 7/8”
•
Panel height: Between 29 3/8” and 30 3/8”.
•
Panel thickness: 5/8” to ¾”
•
1. Measure overall height of cabinet
opening where ice machine will be
(floor to bottom of countertop edge).
2. Determine desired kickplate
space (from bottom of door to floor).
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 adjusted
for height to position top of door to desired
clearance.
4. Subtract 1/8 or more for clearance
space between top of door and
bottom of countertop edge from
cabinet opening. This is the
maximum door length.
5. Cut panel to width.
6. Cut panel to length (cabinet space
- kickplate space - top clearance =
length).
7. Determine top of panel.
8. Mark hole locations using drawing
on the back of these instructions.
Drawing assumes top of panel will
be flush with top of door. Measure
hole locations from the top of the
panel.
9. Drill pilot holes for wood screws.
Use drill stop to prevent drilling
through the panel.

Door swing change
The door can be attached to open with hinges on
the left or right using new brackets shipped loose in
the ice bin. Retain all screws for re-use.
To change:
1. Remove innermost
screw holding each
hinge to cabinet, loosen
the other.
2. Slide hinges to the side
and remove door from
cabinet. Remove
screws loosened in step
1 from both hinge brackets.
3. Remove two screws securing top panel to
back, pull top panel back and remove from
cabinet.
4. Remove two screws at
the top and lift the door
hinge bracket out of the
cabinet. Replace with the
one supplied loose with
the machine. Fasten it to
the cabinet using the
original screws.
Door Hinge
Bracket
8. Remove the upper hinge and move it to the
door's opposite side, bottom location. Secure
using the original screws.
9. Remove the original lower hinge and move it to
the door's opposite side, upper location.
Secure using the original screws.
10. Install a screw removed in step 2 in outermost
hole of upper and lower cross braces.
11. Attach the door to the cabinet using the original
screws.
12. Return kickplate and front service panel to their
original positions and attach to the cabinet
using the original screws.
Installation Notes
Built In Situations: If a finished floor is to be
installed in the area after the ice machine has been
built in, shims the expected thickness of the floor
should be installed under the unit to keep the
machine level with the planned floor 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.
5. Return the top panel to the cabinet and fasten
it with the original screws.
6. Remove kickplate and front service panel.
7. Remove two front screws and two bottom
screws holding the bottom cross brace to the
cabinet. Replace the brace with the one
supplied loose with the machine. Secure it
using the original screws.
Screw Below
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 floor.
Note: When installed in a corner, the door swing
may be limited due to handle contact with the wall
or cabinet face.
