MAINTENANCE

THE FOLLOWING MAINTENANCE SHOULD BE PERFORMED AT LEAST EVERY SIX MONTHS ON

FLAKED ICE MACHINES:

1. Check the incoming electrical power supply while the machine is starting. Voltage must not drop lower than

–5% of the rated name plate voltage. Conditions below the –5% limit will reduce the life of the start compo-

nents, the compressor and the gear motor.

2. Check water level in the float tank. The water level must be maintained at the top of the evaporator. adjust

as necessary. (see illustration.)

3. Clean the air–cooled condenser with a stiff brush and vacuum cleaner.

CAUTION: Condenser fins are sharp. Use caution when cleaning.

4. Clean the ice storage bin and flush the bin drain.

5. If water filter(s) are installed in the inlet water supply, check these filters and replace as necessary. Also

clean the strainer screen at the float chamber inlet.

6. If heavy mineral deposits (scale) are present on the auger or the inside surface of the evaporator clean and

sanitize following the procedure outlined in the Cleaning and Sanitizing section is this manual.

7. Remove the ice chute hold-down nuts and remove the chute from the evaporator shell. Be careful not to

damage the bin thermostat capillary.

A. Remove the cutter head hold down bolt. Mark the extruder head at one of it’s 3 mounting bolts and

remove all three extruder head mounting bolts. Grasp the extruder head and remove it by pulling up-

ward.

B. Check the extruder head bearing for wear or scoring patterns. Should the bearing surface appear

okay, reinstall the extruder. Rotate the extruder 120_ when installing, using the reference mark you

made on the extruder in step A above. See the drawing below.

AB C

C. Should the extruder bearing appear worn or scored, check the bearing with the GO-NO-GO gauge

P/N 630900056. If the gauge passes into the bearing more than 1/2I, replace the extruder head as-

sembly with an exchanged head and bearing assembly from your local distributor.

NOTE: High mineral content in the water may increase the extruder head bearing wear if proper water

treatment is not installed.

8. Activate the dump valve switch several times and be certain the valve opens and fully closes with each ac-

tivation. Should the valve fail to completely close, replace the plunger and diaphram with a replacement kit.

9. Replace the ice chute and check for proper alignment making sure the chute is not blocking the ice flow

path.

10. Check the bin thermostat operation by holding ice against the capillary to open the control thus shutting

down the machine operation.
