grade ice machine cleaner. The water pump is used to circulate the cleaner through the system by
setting the “Clean/Off/Ice” selector switch to “Clean" to start the water pump and to “Off” to stop
the water pump. For complete instructions, refer to the “Cleaning Procedure” attached to the
equipment and duplicated here.
Cleaning Procedure
1. Before cleaning any Tube-Ice machine make sure the crankcase heater is working properly. When the
crankcase heater is not working there is a possibility for refrigerant evaporated by warm circulating water
to migrate to the compressor during the cleaning operation.
2.
Set ‘Clean/Off/Ice” selector switch (SS) to “Off” position. If the machine is running, it will shut down on
completion of the next ice harvest period.
3. Remove ice from storage area or cover ice discharge opening to prevent water from splashing out and
contaminating stored ice.
4. Shut off water supply and drain water tank (13) by opening drain valve (28). Remove any loose sediment
from tank.
5. Close drain valve (28) and fill water tank (approximately 27 gallons) with warm water.
6. Add 72 ounces (8 ounces per 3 gallons) of Calgon
®
ice machine cleaner (a food grade liquid phosphoric
acid) to water tank during the refill period.
7. Inspect the water distributors by looking through clean freeze cover. If required, remove the cover.
Clean and remove any solid particles from the distributor orifices (two orifices in each distributor). Clean
the rubber cover gasket and reinstall the cover.
8. To run the pump only, set the “Clean/Off/Ice” selector switch (SS) to the “Clean” position and press
“Start”.
9. Circulate cleaning solution until deposits are dissolved or solution is neutralized. Repeat cleaning if
necessary.
10. Press “Stop” button to stop pump, then drain and flush water tank with fresh water. Open water supply to
machine.
11. Drain and flush tank and then refill with fresh water.
12. Clean inside of ice storage area and remove any solution that entered during the cleaning process.
Remove cover if one was installed over opening into storage area.
13. Start ice making cycle by setting the “Clean/Off/Ice” (SS) switch to “On”. Check for water leaks around
the freezer cover and tighten nuts if needed.
