7. Maintenance
Ice Making Section.
The ice-making section of the Tube-Ice
®
machine should be cleaned at least
twice a year (more often if water conditions cause mineral build-up). Use an approved food-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" and starting and stopping the pump by the
“Start/Manual Harvest” and “Stop” switch. For complete instructions, refer to the “Cleaning
Procedure” attached to the equipment and duplicated here.
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, 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.
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 15 gallons) with warm water. Close the
petcock on the water pump during the cleaning period.
6. Add 40 ounces (8 ounces per 3 gallons) of Calgon

ice machine cleaner or equivalent (a food grade
liquid phosphoric acid) to water tank during the refill period. Note: Tank capacity = 14.5 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.
