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. For
complete instructions, follow the “Cleaning Procedure” below.
Cleaning Procedure.
1. Stop the machine at the end of harvest.
2. Shut off make-up water supply.
3. Drain the water tank, flushing out any loose sediment.
4. Close the drain valve and fill the tank with warm water. Warm water promotes faster cleaning.
5. Cover the ice discharge opening to prevent water from splashing out and contaminating any
stored ice.
6. Add sufficient ice machine cleaner to the water tank.
P24 tank = 2.5 gallons water per inch of water height in tank, 13” = 32.5 gallons
P34 tank = 4.7 gallons water per inch of water height in tank, 13” = 60.6 gallons
Mix cleaning solution according to manufacturer’s recommendations.
7. Remove top water box cover, inspect distributors, remove any hard particles from orifices, and
make sure all distributors are in place. Replace cover.
8. Turn Hand/Auto switch to “Hand” position and circulate the cleaning solution until deposits are
dissolved or the solution is neutralized. After draining, the pump may have to be stopped and
restarted to dispel air.
9. Turn switch to “Auto” position to stop the pump. Drain and flush the water tank. Repeat
cleaning as necessary.
10. After cleaning, fill the tank with fresh water, start the pump again, and circulate for 15 minutes.
11. Stop the pump, drain and flush the tank and again refill with fresh water.
12. Remove the cover from the ice discharge opening, and clean any area that may have been
splashed with solution during cleaning.
13. Make sure the make-up water float valve is adjusted properly and the drain valve is closed.
14. Start and stop the pump again to make sure it is circulating water and it is not air bound.
You are now ready to produce ice.
Water Distributors.
The water distributors are located under the top freezer cover. These
distributors are similar in design to those used in mid-size and small machines (i.e. P18F, P118, etc.)
except they have a small vent tube. It is important that this plastic vent tube remain in place in each
distributor. The distributors may require occasional or periodic cleaning to remove solids, foreign
particles, or mineral deposit accumulated from the circulating make-up (ice making) water. The
frequency of cleaning operation will depend on the characteristics of the water supply. The
distributors need inspection when the inside diameter of a large portion of the ice becomes irregular
(due to channeling of water), if some of the ice is opaque or if there is a noticeable decrease in ice
capacity and quality.
