6. Pour 2 quarts (2 L) of hot water into the
water pan and turn the Cycle Control
Knob to "CLEAN." This step warms up
the system and allows the cleaning
solution to be more effective. Allow to
circulate 5 minutes. Turn the Cycle
Control Knob to "OFF" and drain.
Prepare the cleaning solution by
thoroughly mixing 6 oz. (170 gm) of
powdered citric acid or phosphoric acid
into 2 quarts (2 L) of hot water. Com-
mercial ice machine cleaners are also
available in liquid form and should be
mixed according to instructions on
the label.
7. Pour cleaning solution into water pan
and turn the Cycle Control Knob to
'CLEAN." If solution foams while pour-
ing, stop until foaming subsides, then
add balance of solution. Allow solution
to circulate until scale has dissolved.
The circulating solution may not contact
scale on the side flanges of the freezing
plate. To remove this scale, wear rubber
gloves and use a stainless steel sponge
or pad dipped in cleaning solution to
scrub the side flanges until scale is
removed. Generally scale will be dis-
solved in 15 to 30 minutes. Severe scale
formation may require repeating the
cleaning process with a fresh quantity of
solution if the scale has not dissolved
after 30 minutes.
6. Turn the Cycle Control Knob to "OFF"
and drain.
9. Follow cleaning with 2 fresh water
rinses, circulating each rinse for
5 minutes, and drain.
10. This completes the "in place" cleaning
and sanitizing of the water system and
freezing plate. Other interior components
must also be cleaned and sanitized.
