WARNING: Most ice machine cleaners are citric or phosphoric
acid which can cause irritation even after dilution. In case of
contact with eyes, flush eyes thoroughly with fresh water and
contact a physician immediately. In case of contact with skin,
rinse well with water. If swallowed, give large amounts of water
and contact a physician immediately. Do not induce vomiting
KEEP OUT OF REACH OF CHILDREN.
6. Pour Vi gallon (1.9 L) of hot tap water into the
water pan and turn the service or cycle switch 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. (170g) powdered citric, or phosphoric
acid into
Vi gallon (1.9 L) hot water
(Citric and phosphoric acid crystals are available
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 instructions on
label (total quantity Vi gallon [1.9 L] ).
7. Turn Service or Cycle switch to "OFF" and
drain tap water, (See step 5.)
8. Turn the switch to "CLEAN" and slowly pour
the hot cleaning solution into the water pan. (If
the 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 30 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 plastic
scrubby or non soap filled stainless steel pad dipped
in cleaning solution.
9. Drain the cleaning solution. Using the rubber
gloves, remove the drain plug and set the switch to
"OFF."
10. Replace the plug and add Vi gallon (1.9 L) of
fresh water. Set switch to clean, circulate five
minutes, drain. Repeat rinsing process.
