SPECIFICATIONS
Always refer to the nameplate, located on the back
of the cabinet, for the:
••model number,
••serial number,
••basic electrical
requirements,
••minimum circuit ampacity,
••maximum fuse size,
••and refrigerant charge.
A serial number plate with the model number,
serial number and refrigerant charge is located
behind the front panel, near the control box.
The unit comes from the factory with the correct
refrigerant charge. The refrigerant charge
information is for recharging, should that be
necessary.
All utility connections are made at the back of the
ice maker.
Before beginning installation, be sure that all of the
components necessary for complete assembly of
the ice system are available, and are the correct
components with regard to model, voltage, and
finish.
Installer: After installation, take this manual with
you, do NOT leave it with the machine.

FOR THE INSTALLER: Environmental Limitations
MCM1062W
Installation Limitations
The ice making portion of this ice system is
designed to be installed indoors, in a controlled
environment.
Minimum Maximum
0
Air Temp 50
Water Temp 40
Water Pressure 20 PSI 80 PSI
Voltage 197 253
Operating the ice machine outside of the above
limitations, or outdoors, is potentially damaging to
the machine; also it is misuse of the machine,
which may void the warranty.
Scotsman Ice Systems are designed and
manufactured with the highest regard for safety
and performance. They meet or exceed the
standards of UL, NSF, and CSA.
Scotsman assumes no liability or responsibility of
any kind for products manufactured by Scotsman
that have been altered in any way, including the
use of any part and/or other components not
specifically approved by Scotsman.

Water Limitations
An ice machine is a food manufacturing plant; it
takes a raw material, water, and turns it into a food
product, ice. The purity of the water is very
important in obtaining pure ice and in maximizing
product life. These general recommendations
should help keep the ice maker clean:
1. Filter the water used to produce ice. Water filters
vary greatly in ability and function. Install one that
filters out suspended solids to a dimension of 5
microns or smaller. The finer the filter the better,
but finer filters will clog sooner than course ones. It
may be necessary to add a course filter ahead of
the fine filter to prolong filter life.
2. Check with a water treatment specialist for a
water test, and recommendations regarding filters
and treatment.
Service Limitations
Some space on the sides, the back and the top
should be allowed for service and utility
connections.
Scotsman reserves the right to make design
changes and/or improvements at any time.
Specifications and design are subject to change
without notice.

FOR THE INSTALLER: Machine & Bin Assembly
Overview:
This ice system is comprised of 2 major
assemblies:
1. The ice storage bin.
2. The ice maker itself.
Storage Bin:
1. Measure the location of the ice machine floor
drain relative to the installed location of the bin.
2. Using corner posts from the bin’s carton as a
cushion, lay the bin on its back.
3. Install the casters into the leg mounting holes.
4. Move bin back to an upright position.
5. Align the back set of casters so that the wheel’s
axles are in a line with each other. This will permit
the bin to be rolled back and forth. Check the
casters so that they are tight against the bottom of
the bin. Do not extend the casters past the
horizontal groove in the caster shank.
6. Remove all material that is packed inside the bin.
7. Hang the scoop and scoop holder from the front
edge of the bin.
Ice Maker:
1. Arrange for proper electric, water and drain.
See instructions for the plumber and for the
electrician.
2. Position the ice storage bin in the selected
location.
3. Level the bin, in both the front to rear and side
to side directions. Tighten the caster set screws
when the leveling is complete.
4. Inspect the bin top mounting gasket which
should be flat, with no wrinkles, to provide a good
water seal when the cuber is installed on top of
the bin.
5. Install the modular cuber on top of the bin using
care to be sure a good seal is made between the
two cabinets, use of a mechanical lift is
recommended. Align the holes in the bottom back
of the cabinet to mate with the two mounting straps
on the top rear of the bin.
6. Use bolts and straps found in the hardware
package to secure the ice machine to the ice
storage bin. Attach the bin bumpers to the bin with
the bolt holding the mounting strap to the bin.
When alignment and leveling are completed,
tighten the bolts to secure the mounting straps.

FOR THE PLUMBER
Water Supply
The recommended water supply line is a 3/8-inch
O.D. tubing with a minimum operating pressure of
20 PSIG and a maximum of 80 PSIG.
A separate water inlet is required for the
condenser water supply.
Connect to cold water supply line with standard
plumbing fittings, with shut off valve installed in an
accessible place between the water supply and
the cuber. ln some cases a plumber will be
required.
Drain Connections:
Drain tubing and fittings are supplied with the ice
bin. All drains are gravity type and must have a
minimum of 1/4-inch fall per foot on horizontal
runs. The drains to be installed must conform with
the local plumbing code.
The water cooled condenser requires a separate
drain line, and is NOT to be vented.
MCM1062W
Install a vertical open vent on the drain line(s) high
point to ensure good draining. The ideal drain
receptacle is a trapped and vented floor drain.

FOR THE ELECTRICIAN: Electrical Connect ions
See the NAMEPLATE for current requiremen ts to
determine wire size to be used for electrical
hookup. The cuber requires a solid chassis to
chassis eart h ground wire. See Wi ring Diag ram.
Be certain the cu ber is conne ct ed to its own
electrical circuit and individually fu se d. Voltage
variation should not exceed ten percent of the
nameplat e rating, even under start ing conditio ns .
Low voltages ca n cause erra tic opera tion and may
be responsible for seriou s da mag e to the
icemaker.
Electrical connections are mad e at the rear of th e
icemaker, inside the junction box.
The cuber is pac kag ed wit h a flexib le cord and
matching recep tacle (not attached), use th em to
make electrical conne ctio n betwe en the icema ker
and the building’s ele ct ric al po wer, if allowed by
local cod es .
All external wiring should conform to the
national, state and local electrical code
requirements. Usually an electrical permit and
services of a licensed elec tr ic ian wil l be
required.

FOR THE INSTALLER: Final Check List
1. Is the ice maker cabinet in a room where
ambient temperatures are within the minimum and
maximum temperatures specified?
2. Is there clearance at both sides of the cabinet
and at the back and top for service and utility
connections?
3. Has water supply pressure been checked to
insure a minimum of 20 PSIG and a maximum of
80 PSIG operating pressure?
4. Is the cabinet level?
5. Check that any shipping material has been
removed from inside the cabinet.
6. Have all electrical and piping connections been
made?
7. Are the Master and Compressor switches on
OFF?
8. Has power been connected to the ice maker?
MCM1062W
9. Is the water supply line shut off valve installed?
10. Check all refrigerant lines and conduit lines, to
guard against vibration or rubbing and possible
failure.
11. Have the bin and cabinet been wiped clean
and sanitized?
12. Has the Field Quality Audit form been properly
