6. Pour solution of ice machine cleaner into sump, to normal operating level. Do not overfill
because it may overflow into bin.
7. Start the ice flaker drive motor and water pump to circulate cleaning solution over the freezing
surface and all water passages. Operate until all scale is removed. This may require from half hour up
to about 2 hours if scale build up is heavy.
8. When system is clean, drain cleaning solution and rinse with 2 or more complete rinses to ensure
that cleaning solution is flushed away thoroughly. At each rinse, fill sump with fresh water and run
drive motor and water pump for 10 minutes, then drain.
TO SANITIZE:
9. Mix a solution of approved sanitizer or mix 16 oz. of household bleach with 2 gallons of warm
water, 90-115
°
F.
10. Pour solution into sump, to normal operating level (as in #6), then re-circulate sanitizing solution
for approximately 20 minutes, by turning on drive motor & pump.
11. Drain solution and rinse thoroughly with fresh water at least twice, following procedure
described in No.8.
12. After ice flaker is thoroughly rinsed, return machine to normal operation by opening water
supply valve and restoring refrigeration.
Water Distribution Tubes
Water distribution tubes should be kept clean and free of any mineral buildup. When they do
accumulate mineral deposits, the flaker must be thoroughly cleaned. Carefully inspect each
distribution tube and fitting for leaks or crack. Replace defective tubes when necessary.
Water Sump
Water sump and pump should be kept clean and free of any mineral buildup. When mineral deposits
accumulate the machine must be thoroughly cleaned. The water sump will be cleaned when you
normally clean the equipment by circulating the ice machine cleaner through the water system. In
extreme cases of mineral or slime buildup, shut off the main power and remove the top covers from the
sump, and using the ice machine cleaner and a scrub brush clean the aluminum casting until the
deposits are removed.
Ice Bin Drip Pan
The ice bin drip pan should be cleaned each time the ice flaker is cleaned. The pan should be wiped
clean to remove any mineral or slime deposits. The drain line should also be flushed to allow
condensate to drain freely from the drip pan.
