Installation and User's Manual for
Residential Nugget Ice Machine
Model SCN60
User's Manual
This manual includes information for the
installation, operation and maintenance of the
SCN60 residential ice machine.
The SCN60 was developed to offer fans of
Scotsman’s Nugget Ice form the ability to have that
ice in their homes. Previously Nugget Ice was only
available in commercial establishments, where it
developed a strong following because of the
chewable nature of the ice. This machine makes
authentic Nugget ice, using the same process as
the larger commercial machines.

Installation Information
RO Water
The cabinet is fourteen and seven eighths inches
wide by thirty three and three eighths to thirty four
and three eighths inches high.
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
Utility and Operational Requirements
• The SCN60 must be connected to a potable
water supply.
The water supply must have a conductivity of
at least 10 microSiemens/cm.
Minimum water pressure: 20 psi
Maximum water pressure: 80 psi
Minimum water temperature: 40 degrees F.
Maximum water temperature: 90 degrees F.
It is designed to operate in wide range of air
• Minimum air temperature: 50 degrees F.
• Maximum air temperature: 100 degrees F.
Although the machine will function within the listed
ranges, it works best at water temperatures
between 50 and 60 and air temperatures between
60 and 80.
Note: Ice making capacity goes down as the
environmental temperatures go up, and will be
severely reduced at temperatures over 90 oF.
Deionized water is not recommended and could
damage the machine.
Because water softeners exchange one mineral for
another, softened water may not improve water
conditions when used with ice machines
Electrical power
The unit must be on its own 115 volt, 60 Hz, 15
amp circuit. It is equipped with a power cord and
can be plugged into a nearby outlet. Extension
cords are not allowed by most codes. Follow all
applicable codes.
Warranty Information
Warranty information is supplied separately from
this manual. Refer to it for coverage. In general, the
warranty covers defects in materials or
workmanship and does not cover corrections of
installation errors or maintenance.
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.

User's Manual
Location Recommendations:
The machine can be built into a cabinet. It is an air
cooled refrigeration system and so air flows in and
out of it through the grill at the bottom front. The
grill must not be blocked by any covering door or
other obstruction.
Drain Conversion: 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 part number is A39462-021.
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.
Note: The water connection is at the back and adds
a few inches to the cabinet depth.
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.
Warm Air Out
Note: When installed in a corner, the door swing
may be limited due to handle contact with the wall
or cabinet face.
Air Intake
There are two models, one is a gravity drain type
and it must have a building drain connection below
the level of the drain tube at the back of the
cabinet; the other is a pump drain model which can
force drain water up a maximum of 10 feet,
allowing it to be located where a gravity drain isn’t
All models require a water supply. Water supplies
vary in the degree of mineral content. High mineral
content water will require more frequent
maintenance. Water filtration may improve the
taste of the ice as well as cut down on some of the
mineral build up.
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.

the machine?
5. Remove service panel for visual inspection.
8. Has the door covering been installed?
6. Pour a couple of quarts of water into the ice
storage bin; on drain pump equipped machines the
drain pump should start and water should pump
out. Check for leaks.
Initial Start Up
1. Turn on the water supply.
2. Switch on the electrical power.
7. Replace the service access panel.
8. 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.
Warm air will flow out of the left front grill.
It will take about 10 minutes for the ice machine to
begin dropping nugget ice into the storage bin. It is
normal for that ice to melt and ice will continue to
melt, but at a slower rate. It will take about 6 - 7
hours to fill up the ice storage bin. The storage bin
holds about 20 lb of ice when full.
Ice level control
The ice level control for the SCN60 is an ultrasonic
sensor, located above the ice storage area. It is
automatic and there is no adjustment to make.
When ice melts or is used, and the ice level drops
below a preset distance the control turns the ice
making system back on. It makes ice until the
preset level is reached. Placing your hand in the
unit to remove ice does not affect the ice level.

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.
The machine can be shut off anytime by just
pushing and releasing the On/Off button.
Ice Making
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.
The ice machine is designed for quiet operation,
but will make some noise during the ice making
During ice making, nugget ice will drop into the bin
at an irregular rate; sometimes there will be little ice
falling while at other times a group of nuggets will
fall. Some water drops may also come out with the
ice. Both conditions are normal.
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

Scotsman strongly recommends regular
maintenance of this ice machine. During normal
operation mineral scale that is in the water supply
will gradually build up on the ice making surfaces.
That build up can cause excessive loading of the
ice making system, which can cause premature
failure. Regular removal of the mineral scale will
lengthen the product’s life.

How to remove scale from the ice making system.
Cleaning this machine involves adding a solution of
scale remover and water to the ice machine and
continuing to add it as it makes ice. The scale
remover must be diluted to the correct ratio. A
squirt bottle will make adding the scale remover
much easier when the unit is built in. If not built in,
remove the top panel for reservoir access.
