NOTE: Before cleaning or sanitizing any Tube-Ice machine, pump the machine down and make sure
the crankcase heater is working properly. This will eliminate the possibility of refrigerant migrating to
the compressor while circulating warm water through the evaporator.

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 the "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 opening into it.
4. Shut off water supply and drain water tank (7) by opening drain valve (39). Remove any loose sediment
from tank.
5. Close drain valve (39) and fill water tank (approximately 6 gallons) with warm water. Close the petcock
on the water pump during the cleaning period.
6. Add 16 ounces (8 ounces per 3 gallons) of Nu-Calgon
liquid phosphoric acid) to water tank during the refill period. Note: Tank capacity = 6 gallons
7. Inspect the water distributors by looking through clear 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 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" selector switch (SS) to "Ice". Check for water leaks
around the freezer cover and tighten nuts if needed
14. Adjust setting of pump petcock per instructions under "Adjustable Blow down" in Section 9.
