Introduction
To the owner or user: This service manual is
intended to provide you, and the maintenance or
service technician, with the information needed to
install, start up, clean, maintain and repair this
product.
The CM500 is an ice machine that produces
cubed ice on 2 vertical cube freezing surfaces.
The cubes fall as vertical strips of cubes into the
ice storage bin where they break up into individual
cubes. The CM500 automatically maintains the
level of ice by turning on when the ice level falls,
and switches off when the bin is full.

Page 2: Specifications
30 x 24 x 27 CM500WE-1E 30 x 24 x 27 The CM500 will stack onto a variety of ice storage bins, see sales literature for proper ice storage bin. There is an optional stainless steel panel kit, SPKCMD-1, for this machine. -
Page 3: Limitations
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. -
Page 4: Installation
It must be installed indoors, in a controlled environment. The air and water temperatures must not exceed rated limits. Pre-installation: 1. Inspect the place where the ice machine is to be installed. Check for: space for the cabinet, water supply, drain availability and electrical power supply. - Page 5 3. Line up the ice machine, check that there is a Capillary Tube good seal between the ice machine and the storage bin. 4. If on a Scotsman bin, attach the ice machine to Bin Thermostat the bin using the straps and bolts shipped with the Bracket ice machine.

Page 6: Plumbing
A loop of copper tubing may be used between the ice machine and the water supply. This will allow the ice machine to be pulled out from its installed location without disconnecting the water line. No back-flow preventer should be needed in the inlet potable water line because provision for that is incorporated in this N.S.F. -

Page 10: Initial Start Up
Note: In some cases some slush will form in the reservoir. This is temporary and normal. 9. Allow the ice machine to operate for about 23 minutes. The ice should be fully formed and should be harvested within a few minutes. - Page 11 Note: Harvest time is dependent upon the water and air temperatures at the ice machine. Colder air and water will result in faster ice making, but longer harvest cycles. Do NOT adjust harvest time too short, as this will case a freeze up of the evaporators.

Page 15: Water/ Refrigeration Schematic
Valve Water Reservoir Water Schematic: Water flows into the ice machine from its inlet connection at the back of the cabinet, through the inlet water valve and into the reservoir. The water in the reservoir is pumped up and through the water distributor tube at the top of the evaporators. -
Page 16: Harvest Cycle
CM500 Harvest Cycle: During the harvest cycle, the refrigerant flows from the condenser, through the discharge line to a branch in the line containing the Hot Gas Valve. This valve is Open during the harvest cycle, allowing the hot discharge gas to bypass the condenser and enter the evaporator at its inlet. -
