SPECIFICATIONS
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.
A stacking kit (KSCMS) is required for stacking
CME1002 or CME865 ice machines. It
interconnects the sonar bin ice level controls. A
CME865 or CME1002 may only be stacked onto
models CME865, CME1002, MCM1062 or
CMS1002.
The CME865 or CME1002 will fit any current 30"
wide Scotsman bin, such as the BH550 or
HTB555, without needing a bin top. Other bins will
require a bin top.
Note: The sonar transducer, located in the base of
the machine, must NOT be covered by installation
material (such as a non-Scotsman bin top). The
transducer must have clear access to the ice to be
able to sense the ice level.

PRODUCT INFORMATION
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.

The ice making portion of this ice system is
designed to be installed indoors, in a controlled
environment.

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.
When servicing a machine, it’s helpful to compare
that unit’s operating characteristics to those of a
new, clean, normally operating machine. What
follows is that type of information:
Service Limitations
Some space on the sides, the back and the top
should be allowed for service and utility
connections.
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:
After uncrating the ice storage bin, attach the legs
to the bin:
1. Use a portion of the carton as a cushion, and tip
the storage bin on its back.
2. Screw the legs into the threaded holes in the
bottom of the bin.
3. Turn the leg levelers all the way in to prepare
the bin and ice machine for leveling.
4. Return the bin to the upright position.
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
INDOOR location.
3. Level the bin, in both the front to rear and side
to side directions.
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. When alignment and leveling are
completed, tighten the bolts to secure the
mounting straps.

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. In some cases a plumber will be
required.
CONFORM TO ALL LOCAL CODES
Drain Connections:
Connections: All drains are gravity type and must
have a minimum of 1/4 - inch fall per foot of
horizontal run. The drains to be installed must
conform with the local plumbing codes. Install a
vertical open vent on the ice machine reservoir
drain. The ideal drain receptacle is a trapped and
vented floor drain. The storage bin drain should be
insulated.
Water Cooled Connection: A separate cold water
supply is required, connect to the 3/8-inch FPT
fitting at the back of the cabinet. An additional
drain line is required to drain the water cooled
condenser, and must not interconnect to any of the
other drains.

FOR THE ELECTRICIAN: Electrical Connections
See the NAMEPLATE for current requirements to
determine wire size to be used for electrical
hookup. The cuber requires a solid chassis to
chassis earth ground wire. See Wiring Diagram.
Be certain the cuber is connected to its own
electrical circuit and individually fused. Voltage
variation should not exceed ten percent of the
nameplate rating, even under starting conditions.
Low voltages can cause erratic operation and may
be responsible for serious damage to the
icemaker.
Electrical connections are made at the rear of the
icemaker, inside the junction box.
ELECTRICAL JUNCTION BOX
All external wiring should conform to the
national, state and local electrical code
requirements. Usually an electrical permit and
services of a licensed electrician will be
required.
