CS0415 Service Manual Specifications Scotsman Ice Systems are designed and manufactured with the highest regard for safety and performance. They meet or exceed the standards of agencies like NSF and UL.. Storage Capacity (Approximate) • 24 lbs. (10.9 kg) Exterior Dimensions (W x D x H) Scotsman assumes no liability or responsibility of any kind for products manufactured by Scotsman • 15" x 24" x 34" (381 or 457.2 x 609.6 x 863.
CS0415 Service Manual Installation: The ice machine is designed to be installed indoors, in a controlled environment. Do not place where the temperature limits for air or water are exceeded. The water supply must be cold, potable water. A drain must be nearby or a drain pump model used or a gravity drain model must be converted to use a drain pump. The ice machine must be on its own electrical power circuit. The machine must be grounded. Do not connect to an extension cord.
CS0415 Service Manual Test Mode - Ice Thickness Adjustment The CS0415 has three push button switches: ON, OFF and CLEAN. These can be used to switch the machine on, off and to start the cleaning process. They can also be used to test the unit's components. Test 9, no component tested. To test and/or to adjust ice thickness: The Off light is the indicator. Test 10, displaying the ice thickness setting. Ice Thickness Adjustment. • If it blinks 2 times and repeats, the ice 1.

CS0415 Service Manual Operational Modes: There are four main operational modes for the ice maker: • • • • Freeze Harvest Clean Service (Diagnostics) Ice Making Cycle In addition, there are three possible “Off” cycles for the ice maker. They occur when: 1. The bin is full of ice and the LED is illuminated “ON/OFF” (Idle mode). 2. The “On/OFF” control switch has been held for three seconds. The ON/OFF LED will go out.
CS0415 Service Manual Harvest Mode Electrical System When the water level in the reservoir drops below the water level sensor it signals the electronic control to terminate power to the condenser fan, and then the water recirculating pump. The reservoir drain pump is activated to fully drain the reservoir. Power is then supplied to the hot gas valve and a fill request is sent to the measured fill valve.

CS0415 Service Manual Diagnostic Mode Do not continue with the diagnosis of the ice maker if a fuse is blown, a circuit breaker is tripped, or if there is less than a 120 volt power supply at the wall outlet. Units that failed during the first few days of use should be checked for loose connections or miswiring. Entering and Navigating — Manual Diagnostics Turn the product to On. Within 10 seconds of Power On, press and hold the On and the Clean buttons.
CS0415 Service Manual Error Displays These errors will occur at any time during normal operation if a thermistor fails. • 2 Blinks - Off Light is blinking twice in repeating intervals – This signals a bin thermistor failure. Check that the bin thermistor is plugged in to the control box. Check that the bin thermistor is not open or shorted. Replace the thermistor if it is open or shorted. • 3 Blinks- Off Light is blinking three times in repeating intervals – This signals a harvest failure.
CS0415 Service Manual Component Testing Before testing any of the components, perform the following checks: • Control failure can be the result of corrosion on connectors. Therefore, disconnecting and reconnecting wires will be necessary throughout test procedures. • All tests/checks should be made with a VOM or DVM having a sensitivity of 20,000 ohms per- volt DC, or greater.
CS0415 Service Manual Component Testing d) Turn the relay over so that the coil faces up, as shown below. Water Level Sensor 1. Run the diagnostic tests and check for the proper operation of the water level sensor in step 4b. e) With the tip of the ohmmeter test leads at the Start (S) and Run (M) pin sockets, the meter should indicate a closed circuit (0 ohms). 2. With the water level sensor immersed in water the Service LED should stay on solid. 3.
