CLEANING AND SANITIZING THE ICE MAKING SYSTEM
Ice making system:
The minerals rejected from the circulating water during.
the freezing cycle will eventually form a hard scaly
deposit in the water system which prevents a rapid
release of the ice.
Clean-ice and water system periodically to remove
mineral scale build-up. Frequency of cleaning depends
on water hardness. With soft water, cleaning may not be
required for several years. With hard water (15 to 20
grains/gal.) cleaning may be required as frequently as
every six months.
To clean and sanitize, follow this procedure: *
*Approved by the National Sanitation Foundation.
1.
Place cycle or service switch in "OFF" position.
FIGURE 4
2.
Remove the two thumb screws and slide the ice
cutter grid out of the two slots near the water pan.
3.
Unplug the electrical harness.
Any ice on the grid should be melted under running warm
water. Attempting to pick the ice slab off the grid may
stretch and damage grid wires.
4.
Remove all ice from the storage bin and the
freezing plate.
5.
Drain the water pan by removing the drain plug
(Figure 5) and then replace the plug.

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 1/2 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 1/2 gallon (1.9 L) hot water
(Citric acid 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 1/2 gallon [1.9 L]).
7.
Turn service or Cycle switch to "OFF", drain tap
water and replace plug.
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 curculate 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 1/2 gallon (1.9 L) of
fresh water. Set switch to clean, circulate five minutes,
drain. Repeat rinsing process.
