User manual SCOTSMAN CME1002R

[. . . ] CME865R & CME1002R INTRODUCTION This manual is intended as a reference for the installation and service of a Scotsman ice maker model CME865R or CME1002R. This model is a remote condenser cuber, 30" wide and should be connected to a Scotsman remote condenser.

FOR THE INSTALLER: Environmental Limitations . [. . . ] Harvest is preset at 2 and a quarter minutes. Hot Gas Solenoid Valve The hot gas solenoid valve opens only during the harvest cycle. When it opens, it diverts the hot discharge gases so that they flow directly into the evaporator plates, by-passing the condenser and thermostatic expansion valve. The hot gases warm the evaporators, releasing the ice cubes from the ice cube molds. The hot gas solenoid valve is installed in a branch of the discharge line from the compressor, and when the timer switches the ice machine into the harvest cycle, the energized solenoid coil lifts the valve stem within the valve body, allowing the hot discharge gas to be diverted to the evaporators. High Temperature Cut Out This temperature sensor is located next to the hot gas valve, on the outlet side. During normal operation, it does not affect the ice machine, but it will shut the machine off if the hot gas line overheats. It is an automatic reset. September, 1994 Page 15 CME865R & CME1002R COMPONENT DESCRIPTION Ice Level Control This electronic control uses sound waves to measure the distance between the bottom of the ice machine and the top of the ice in the bin. It is designed to control the machines ice production to maintain that distance. The control is adjustable so that the ice machine will maintain a certain height of ice. It will not fill any closer to the ice machine than 8", and will not work if the distance to the bottom of the bin is greater than 8 feet. Because it uses sound waves, a slight "ticking" sound can be heard coming from the bottom of the machine. ON/OFF/WASH SWITCH ICE LEVEL SELECTOR SWITCH THE USER CAN SELECT THE AMOUNT OF ICE TO BE MAINTAINED IN THE BIN. FULL PARTIAL September, 1994 Page 16 CME865R & CME1002R COMPONENT DESCRIPTION Electric Water Inlet Valve The water inlet solenoid valve fills the reservoir assembly with water. Excess water overflows out the overflow standpipe located at the back of the reservoir. This action fills and rinses the reservoir during each harvest cycle. Water Distribution System The water distribution system evenly supplies water to all cells of the evaporator plates. The water pump pumps water from the reservoir up the vertical tygon tube to the tee. From there water is channeled through the water manifold to the water distributors, above each evaporator plate, and from six holes within each distributor, water flows to the cells of each side of the evaporator plates. Gravity flow returns the unfrozen excess portion of water to the reservoir for recirculation. Reservoir The reservoir, located below the evaporators, stores the inlet water charge, and collects the water that flows over the evaporator plates. High Pressure Safety Control This is a manual reset control that shuts down the ice maker, should the discharge pressure ever reach 450 PSIG.
