Outdoor Use Notice:
Keep from freezing. Severe damage will occur to the unit if left in or operated in temperatures beyond
the limits listed in this manual. That damage is NOT covered by warranty.
Keep dry
Provide Shade
ultraviolet radiation from the sun can potentially damage the unit's plastic components.
. Do not locate in low lying areas where puddles will accumulate.
: Heat gain from the sun will reduce the unit's ability to make and store ice, and
Water Supply
: Avoid a long run of hose or tubing exposed to the sun. Plastic water supply tubing
should be rated for potable water and include UV protection. Copper tubing is recommended.
Back Flow Prevention
Drainage
: Do Not drain into swimming pool or onto grounds.
: The unit includes back flow prevention, no additional check valve is required.

User's Manual
Product Description:
This ice machine is designed to be used indoors, in
a controlled environment or outdoors within certain
limits.
The NU130 is made up of two major systems: the
ice making system and the ice storage system. The
ice making system is a continuous flow type ice
machine, it makes ice when the ice level becomes
low and stops when it is full.
The ice storage system is an insulated chest with a
drain at the bottom for melting ice. It is not
refrigerated, insuring that the bin contains fresh ice.
Installation Information
Dimensions:
The cabinet is fourteen and seven eighths inches
wide by thirty three and three eighths to thirty four
and three eighths inches high.
Utility and Operational Requirements
• The NU130 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.
Water Quality
The water to the machine must be potable, or fit for
human consumption. Beyond that, water supplies
vary in the degree of mineral content. As this ice
machine makes ice, all the water that flows into the
machine is changed into ice. That includes any
minerals that might be in the water. However,
during ice making some minerals will stick to the
ice making components. The higher the mineral
content, the more mineral build up will occur. Water
filters are a partial help, as they will remove the
suspended solids, but water treatment is needed
for the dissolved solids, which are part of the water
and cannot be filtered out.
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 or
blending to satisfy the R.O. water’s potential
aggressiveness.
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
It is designed to operate in wide range of air
temperatures:
•
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
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.

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.

Scotsman Ice Systems are designed and manufactured with the highest regard for safety and
performance. They meet or exceed the standards of agencies like ETL.
Scotsman assumes no liability or responsibility of any kind for products manufactured by Scotsman that

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. Minimum
clearance is 0 in. at the top, 2 in. at the rear and
1/8 in. at each side.
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.
Warm Air Out
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
available.
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.
Air Intake
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.
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.
