Cleaning and Caring
Continued
6. Pour 1/2 gallon (1,9L) of hot tap water into the
water pan* and turn the Cycle Control Knob to
“CLEAN.” This warms up the system to make
the cleaning solution more effective. Let
circulate for five minutes. While tap water is
circulating, prepare cleaning solution. Mix:
6 oz. (170 g) powdered citric,
or phosphoric acid into
1/2 gallon (1.9 L) hot water
(Citric and phosphoric acid crystals are
available or can be ordered from many
pharmacies or scientific supply houses.)
Commercial ice machine cleaners (liquid) are
also available from your dealer or refrigeration
parts supply stores. Mix according to instruc­
tions on label (total quantity 1/2 gallon [1.9 L]).
7. Turn Cycle Control Knob to “OFF” and drain
the water pan. (See step 5.)
8. Turn the Cycle Control Knob to “CLEAN” and
slowly pour the hot cleaning solution into the
water pan.* (If solution foams while pouring,
wait until foaming stops.) Then add the balance
of the solution.
Allow solution to circulate until the scale has
dissolved (15 to 20 minutes). Severe scale
build-up may require repeated cleaning with a
fresh quantity of cleaning solution.
To clean scale off the side flanges of the
freezing plate, use rubber gloves and scrub
with a non-abrasive plastic scrubbing pad or
nylon brush dipped in cleaning solution.
9. Keep rubber gloves on to drain the cleaning
solution. Turn the Cycle Control Knob to “OFF”
and drain the water pan. (See step 5.)
10. Replace the plug and add 1/2 gallon (1.9 L) of
fresh water.* Set Cycle Control Knob on
“CLEAN,” circulate five minutes and drain.
Repeat rinsing process.
* For easier pouring of water and cleaning solution,
use a 1 - or 2-cup container.
