MAINTENANCE
THE FOLLOWING MAINTENANCE SHOULD BE PERFORMED AT LEAST EVERY SIX MONTHS ON
FLAKED ICE MACHINES:
1. Check power supply with machine running for proper voltage.
2. Check water level in the float tank reservoir. Water level should be maintained at the top of the evaporator.
Adjust if necessary. (See illustration and adjustment procedure)
3. Clean the air–cooled condenser coil with a stiff brush or vacuum cleaner (See procedure)
CAUTION: CONDENSER COOLING FINS ARE SHARP, USE CARE WHEN CLEANING.
4. Clean the ice storage bin and flush the bin drain at least once a month.
5. If a water conditioner is installed in the inlet water line, change, replace, or clean the filter, strainer or car-
tridge as required.
6. If heavy mineral deposits on the auger and evaporator shell are encountered due to bad local water condi-
tions, follow sanitizing and cleaning procedure.
7. Loosen hold–down cam locks and remove gearmotor assembly.
8. Check thrust washer; replace if noticeably worn.
9. Lift out auger and examine for wear. The corkscrew auger guide bushing pressed into the drive block
should be checked for wear. Replace if loose or if worn flat with auger drive block. If the Helix auger on
the corkscrew auger round bar becomes flat on the inside more than 1/8 of an inch over a length of two
inches or more it should be replaced.
NOTE: HELIX AUGERS DO HAVE MACHINED FLAT RELIEF SURFACES. DON’T CONFUSE THEM WITH
WORN FLAT AREAS.
Check the insert in the bottom ring of the Helix auger and replace if excessively worn.
10. Check shell vertical strips for wear. Replace the shell if excessive wear is shown.
11. Check O–Ring, replace if worn or cut.
12. Re–assemble, steps 7through 11.
CAUTION: IN RE–ASSEMBLING THE AUGER GEARMOTOR, THE HOLD DOWN CLAMPS
MUST BE RIGHT AND SECURE. IN RE–INSTALLING THE EVAPORATOR SHELL, BE
ABSOLUTELY SURE THAT THE ”O” RING IS NOT PINCHED OFF AS THIS WOULD CAUSE A
WATER LEAK AROUND THE BASE OF THE EVAPORATOR. LUBRICATE THE ”O” RING WITH
FOOD GRADE LUBRICANT BEFORE RE–ASSEMBLING SHELL.
13. Check for alignment of ice chute. Make sure chute gasket is not blocking path of ice flow.
14. Check bin thermostat operation. In the mid–range position the bin thermostat will open at 42_ and has a
6_ differential.
