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 parts and/or other components not specifically approved by Scotsman. Scotsman reserves the right to make design changes and/or improvements at any time. [. . . ] The following is a list of recommended maintenance that will help keep the machine running with a minimum of problems. Maintenance and Cleaning should be scheduled at a minimum of twice per year. Drain the water reservoir and freezer assembly using the drain tube attached to the freezer water inlet. Return the drain tube to its normal upright position and replace the end cap. Prepare the cleaning solution: Mix eight ounces of Scotsman Ice Machine Cleaner with three quarts of hot water. The water should be between 90-115 degrees F. Scotsman Ice Machine Cleaner contains acids. After draining the reservoir, as in step 6, wash and rinse the water reservoir. A possible sanitizer solution may be obtained by mixing two gallons of warm (90-115oF. ) potable water with 1 ounce of household bleach. Slowly pout the sanitizer solution into the water reservoir until the float rises, then switch the master switch ON. As the ice machine uses water from the reservoir, continue to pour the sanitizer solution into the reservoir. After 12 of the sanitizer solution has been added to the reservoir, and the reservoir is nearly empty, switch the master switch OFF. Unit off due to master switch in Off position Unit off due to low water level in reservoir Unit off due to ice level sensors (photo-electric eyes) blocked Unit off due to scale on water level sensor Auger motor hums but does not turn Probable Correction Restore power Move master switch to ON Check water supply, filter and float valve. Check/clean ice level sensors No ice, auger motor is turning Unit makes ice, but very slowly Clean water level sensor Auger can't turn. Auger turning but there is no refrigeration Liquid line valve not opening, effect check coil, check board relay. Unit is shut down Circuit board has shut ice machine down due to high auger motor amp draw. Check for cause of high amp draw, including bearings, gear motor condition and scale on auger & evaporator. Auger not turning Due to: motor failure; auger relay failure on circuit board; or gears stripped. Low suction pressure Liquid line valve not opening due to coil failure or failure of compressor relay on circuit board EPR setting too low, check/adjust TXV restricted or not metering. No power to circuit board Check harness Circuit board gear motor relay will not close Check / replace board Water level or ice level sensor failed Check / replace sensor Liquid line valve coil is open Check / replace valve coil Circuit board relay will not close Check / replace board High discharge pressure because of dirty Clean condenser. condenser Auger and evaporator are coated with Clean the water system minerals Low suction pressure due to low EPR Adjust EPR, check TXV setting superheat November 2000 Page 18 SERVICE DIAGNOSIS Symptom Water Leak Possible Cause Drain plugged up Tubing cracked Condensation on drain tubing Hose off Reservoir cover off Reservoir cracked Evaporator water seal leaks Double System RL Probable Correction Clean out drain Replace tubing Insulate tubing Reattach hose Return cover to reservoir Replace reservoir Check base of evaporator & drip pan. If the seal leaks, shut off the water, remove the auger, replace the water seal. Drains must be separate. Uses too much water Excessive ice meltage Reservoir float valve leaks thru Bin drain clogged Improper installation of drains, they are connected. Poor fit between bin door and door Adjust or replace frame Machine makes too much noise Evaporator coated internally with minerals Motor bearings dry Clean with Scotsman Ice Machine Cleaner Oil or replace motor November 2000 Page 19 Double System RL The control system consists of: CONTROL SYSTEM DIAGNOSTICS ·Control Board ·Water Sensor ·Ice Sensors the water. [. . . ] If the original water seal was leaking, it would be a good idea to inspect the interior of the gearmotor. Moving Parts Hazard. Disconnect electrical power before beginning. To Remove the Water Seal: (Assuming all steps to remove the auger have been performed. ) 1. Remove the 4 hex head cap screws holding the evaporator to the gearmotor assembly. Remove the snap ring or wire retainer from the grove under the water seal. [. . . ]
