Cleaning and Sanitizing (continued)
5. Add recommended amount of approved Nickel Safe ice machine cleaner to the water trough
according to label instructions on the container.
6. Initiate the wash cycle at the ICE/OFF/WASH switch by placing the switch in the “WASH”
position. Allow the cleaner to circulate for approximately 15 minutes to remove mineral
deposits.
7. Depress the purge switch and hold until the ice machine cleaner has been flushed down the
drain and diluted by fresh incoming water.
8. Terminate the wash cycle at the ICE/OFF/WASH switch by placing the switch in the “OFF”
position. Remove the splash curtain and inspect the evaporator and water spillway to assure all
mineral residue has been removed.
9. If necessary, wipe the evaporator, spillway and other water transport surfaces with a clean soft
cloth to remove any remaining residue. If necessary, remove the water distribution tube,
disassemble and clean with a bottlebrush, see page D2. Reassemble all components and
repeat steps 4 through 7 as required to remove residue.
10. Turn OFF ice machine water supply and clean the water trough thoroughly to remove all scale
or slime build-up. If necessary, remove the water trough to reach all splash areas and float.
11. Prepare 1½ to 2 gallons (5.7 to 7.5 liters) of approved (EPA/FDA) sodium hypochloride food
equipment sanitizer to form a solution with 100 to 200 ppm free chlorine yield.
12. Add enough sanitizing solution to fill the water trough to overflowing and place the
ICE/OFF/WASH switch to the “WASH” position and allow circulation to occur for 10 minutes
and inspect all disassembled fittings for leaks. During this time, wipe down all other ice
machine splash areas, plus the interior surfaces of the bin, deflector and door with the
remaining sanitizing solution. Inspect to insure that all functional parts, fasteners, thermostat
bulbs (if used), etc. are in place.
13. Depress the purge switch and hold until sanitizer has been flushed down the drain. Turn ON
the ice machine water supply and continue to purge to the diluted sanitizing solution for another
1 to 2 minutes.
14. Place the ICE/OFF/WASH switch to the “ICE” position and replace the front panel.
15. Discard the first two ice harvests.
