10. In cases where light deposits of scale are
found circulate a vinegar and water solution
(1 quart of vinegar to a full water pan) and
operate the water pump separately by turning
the selector switch to "Pump" position. Cir­
culate 20-30 minutes, drain, open the water
supply line and flush twice.
11. For heavy scale conditions, first remove all
ice from bin. Mix inhibited muriatic acid solu­
tion as described in Section 9.
Circulate approximately 20 minutes, drain and
flush.
12. Then circulate Baking Soda solution for 10
minutes, drain and flush.
13. To clean algae from the water system, use hy­
drogen peroxide mixed with equal parts of
water. Circulate for 20 minutes. Pour some
solution into overflow trough and flush the
system.
14. Start up the unit and time it through one com­
plete cycle. While doing this, clean out the
bin by using soap and warm water or a cleaning
solution approved by local health codes.
Flush out the bin after cleaning.
15. Catch the ice from the first harvest and throw
it away. At every inspection, steps 1 through
7 should be followed. Steps 8 through 15
should be followed if required. Local health
codes should be observed.
When cleaning the water system, pour some of the
solution into the evaporator overflow trough and
allow it to flow into the overflow well. Allow it
to remain in the overflow well for 20 - 30 minutes,
then flush with the same solution used to flush the
water system. Check the main control capillary
and wipe if necessary.
16. WATER PUMP LUBRICATION
The water pump is equipped with orl tubes and
should be oiled with a few drops of SAE 20 motor
oil, every ninety days.
C A U T I O N : D O N O T drop oil in the water pan - it
will adversely affect the freezing process.
The oiling instructions are prominently displayed
on the pump:

17. TESTING AND REPLACING THE
WATER PUMP
The water pump, with a built in overload, is
powered by a 1/30 HP totally enclosed motor and
circulates approximately 10 gallons of water per
minute in the 26H5 and 5 gallons per minute in the
26H3. The 26H5 pump hafe two outlets and the 26H3
one which causes the difference in the rate of flow.
Remove the front, top and left side panels to gain
access to the pump. See Fig. 2K To test, attach
a test cord directly to the pump leads. To replace,
remove the mounting plate screws and splash de­
flector panels and lift the pump assembly out of
the water compartment.
