Installation and User's 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)
Door Panels: Finished door panels are available
from Scotsman for attachment to the machine, or a
custom panel can be made. The panel kits are:

Kickplate Extension: In some situations the leg
levelers will be extended enough to become visible.
A kit to extend the kickplate over the legs is KKPF.
Cabinet Stability: In some free standing
installations it may be prudent to add a bracket that
secures the back of the cabinet to a wall. That kit
number is KATB.
Drain Conversion: A gravity drain model can be
converted to a drain pump model by installing a

The part number is A39462-021.
Electrical voltage limits:
• Minimum - 104 volts
• Maximum – 126 volts
Warranty Information
Warranty information is supplied separately from
this manual. Refer to it for coverage. In general, the
warranty covers defects in materials or

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.

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.
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
RO Water
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.
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

Custom 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.
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:
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.
3. Place the panel onto the outside of the door,

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.
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.

Note: If you are connecting a gravity drain model
and the drain opening has been located in the floor
under the base pan according to the pre install
specifications, follow steps 3 through 5 to drain the
unit through the base. If not, proceed to step 6b.
3. Remove the clamp and barbed elbow and take

1. Turn on the water supply.
6. Replace the service access panel.
2. Switch on the electrical power.
7. Level the unit as needed.
3. Push and release the On/Off switch to start the
machine. The Ice Making light next to the
On/Off switch will glow Green.
4. Water will begin to flow into the unit. When the
reservoir is full, water will start to drain from the
machine. After a few minutes the compressor,
water pump and fan motor will begin to operate
and the first ice making cycle will have begun.
No adjustments are needed.
After about a half hour, ice will fall into the ice
storage bin. The machine makes 24 cubes per
batch. It is normal for the first batches of ice to
melt, that continues until the bin has cooled. It will
take 8 to 10 hours of continuous run time to fill the
ice bin. When the bin is full of ice, the ice machine
will shut off. It will automatically restart when the
ice level falls, either from use or normal meltage.

No special instructions are needed for use. Just
take as much ice as you need, the machine will
replace it. A scoop is provided, and it can be stored
in the machine using the loop of tubing on the right
side as a holder. That tubing is also the ice level
sensor; ice will fill the storage bin until it's near to or
on that tube and then the machine will shut off.
The machine can be shut off anytime by just
pushing and releasing the On/Off button. The
machine will shut off at the end of the next cycle.
To shut off immediately, push and hold the On/Off
button in until the machine stops.
What shouldn’t be done?
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

How to clean the condenser and winterize.
Condenser cleaning
The condenser is like the radiator on a car, it has
fins and tubes that can become clogged with dirt
and lint. To clean:
1. Clean the ice making system.
2. Open the door and push and release the On/Off
switch to turn the machine off.
1. Remove the kickplate and front service panel.
3. Turn off the water supply.
2. Locate the condenser surface.
4. Drain the water reservoir by removing the rubber
cap under the reservoir - it's near the back wall of
the ice storage bin.
Rubber Cap
5. Disconnect the incoming water line at the inlet
water valve.
3. Vacuum the surface, removing all dust and lint.
6. Open the door, push and release the on/off
switch to turn the machine on.
Caution: Do not dent the fins.
4. Return the kickplate and front service panel to
their original positions. Fasten them to the cabinet
using the original screws.
7. Blow air through the inlet water valve; a tire
pump could do the job.
8. Drain pump models should have about 1/2
gallon of RV antifreeze (propylene glycol) poured
into the ice storage bin drain.
Note: Automotive antifreeze must NOT be used.
9. Switch off and unplug the machine.
