1. SERVICE DIAGNOSIS IS100 and IS150 PROBABLE CAUSE 1 No ice in hopper PROBLEM Will not dispense ice CORRECTION 1 Fill hopper with ice 2 Vend switch does not close 2 Check vend switch replace if open 3 Drive motor will not run 3 Check drive motor replace if not working 4 Door solenoid will not open door 4 Check replace door and solenoid 5 Rotor will not turn 5 Check hub of rotor 6 Relay for vend switch does not close during operation 6 Check relays replace if necessary ELECTRICAL SEQUENCE Refer to the wiring diagram Ice Vending Ice is dispensed as long as the ice vend lever or push button is pushed or until the hopper is empty of ice When the ice vend lever or push button is pushed the vend switch closes and makes a circuit to the coil of relay A When relay A is energized relay A s contacts 6 9 and 7 4 close Relay A s contacts 7 1 open When relay A s contacts 6 9 close they make a circuit to the door solenoid which opens the ice door When relay A s contacts 7 4 close they make a circuit to the coil of relay B When relay A s contacts 7 1 open the circuit to the timer is opened When relay B s coil is energized it closes a circuit to the gearmotor and the motor turns the rotor Stand By Relay A s contacts 7 1 are closed and make a circuit to the timer The timer is energized when the unit i2. be dispensed for as long as the button is held in or until the hopper is empty Daily Check 1 Make sure drip tray and grill are clean 2 Remove cover and pour sanitary ice into the hopper Do NOT use bagged ice directly from a freezer The ice must be broken up in the bags first before adding to the hopper Large chunks of ice can NOT be dispensed The dispenser must always contain ice to have ice available for use Keep the cover in place and check the ice supply regularly during operating hours 3 Keep sink clear of spilled ice 4 At the end of the day Remove the grill from the sink clean the sink grill and splash panel make sure the sink drain is open by pouring hot water into the sink Return the grill to the sink October 1993 Page 5 IS100 and S150 HOW IT WORKS The ice is stored in a hopper and the hopper is sloped towards the front At the front there is an angled rotor when that rotor turns it scoops the ice lifts it to the top of the ice chute and drops it through that chute into the user s container CUT AWAY VIEW ICE DOOR UPPER ICE CHUTE ICE CHUTE October 1993 Page 6 IS100 and IS150 CLEANING AND SANITIZING The sink grill and splash panel area should be cleaned daily The ice storage system should be sanitized monthly Daily 1 Lift up and remove grill from sink 2 Use soap hot water and a clean cloth to wash sink and splash panel rinse
