Product Pump
FUNCTION
Transfers product from bag to pitcher.
SPECIFICATIONS
Pressure operated, requires a minimum pressure of 40
PSI (276 kPa). Maximum pressure is 90 PSI (621 kPa).
CHECK PROCEDURE
1. Verify cabinet temperature is not below freezing. A
frozen pump can be thawed and made operational.
2. Perform “clearing a blocked pump procedure”.
3. Verify pressure regulator setting is correct.
4. Verify pressure is present at product pump inlet.
5. Disconnect pressure inlet line and product inlet and
outlet lines from product pump.
6. Point pump inlet/outlet away from face and
reconnect inlet pressure line:
• Pump does not cycle - Replace pump.
Solenoid Valves
FUNCTION
Instantaneously stops fl ow of product through product
tubing.
Shaver Motor
FUNCTION
Turns shaver wheel to supply shaved ice.
SPECIFICATIONS
Shaver motor has a circuit breaker and diode bridge
block. Both components are located in the IO board
compartment near the shaver motor.
Volts Direct Current (VDC)
Normal Room Temperature Resistance:
120 VDC = 30 ohms or less
230 VDC = 15 ohms or less
CHECK PROCEDURE
NOTE: Use an multimeter to check operation. Deduct
meter and lead resistance from fi nal readings (short
leads together to determine deduction value).
1. Reboot machine by moving toggle switch off/on.
2. Test run manual from touchscreen.
3. Test rectifi er - correct readings are:
• Line voltage alternating current (VAC) inlet power
• Line voltage direct current (VDC) outlet power
1. Inspect for correct wiring from rectifi er to shaver
motor.
2. Isolate shaver motor by disconnecting wiring
connectors.
3. Check motor winding resistance through terminals
with an ohm meter.
• Within resistance range = Motor is good
• Outside resistance range = Replace motor
• Open = Replace motor
