Sanitizing Procedure
Use sanitizer to remove algae or slime. Do not use it
to remove lime scale or other mineral deposits. To
initiate a sanitizing cycle using Manitowoc’s
Patented Cleaning/Sanitizing Technology use the
following procedure.
Step 1
Set the toggle switch to the OFF position
after ice falls from the evaporator at the end of a
Harvest cycle. Or, set the switch to the OFF position
and allow the ice to melt off the evaporator.
CAUTION
Never use anything to force ice from the
evaporator. Damage may result.
Step 2
To start a sanitizing cycle, move the toggle
switch to the CLEAN position. The water will flow
through the water dump valve and down the drain.
The Clean light will turn on to indicate the ice
machine is in the Cleaning mode.
Step 3
Wait about one minute or until water starts to
flow over the evaporator.
Step 4
Add the proper amount of Manitowoc Ice
Machine Sanitizer to the water trough.
Model
Amount of Sanitizer
Q1800 6
ounces
(180
ml)
Step 5
The ice machine will automatically time out a
ten-minute sanitizing cycle, followed by six rinse
cycles, and then stop. The Clean light will turn off to
indicate the sanitizing mode is completed. This
entire cycle lasts approximately 25 minutes.
Note:
Periodic cleaning must be performed on
adjacent surface areas not contacted by the water
distribution system. If the bin requires sanitizing,
remove all of the ice and sanitize it with a solution of
1 ounce (30 ml) of sanitizer with up to 4 gallons
(15/l) of water.
Step 6
When the sanitizing process stops, move the
toggle switch to the ICE position to start making ice
again.
Step 7
A.
The ice machine may be set to start and finish
a sanitizing procedure, and then automatically
start ice making again.
B.
Wait about one minute into the sanitizing
cycle (until water starts to flow over the
evaporator), then move the switch from
WASH to ICE position.
C.
When the sanitizing cycle is completed, the
clean light will turn off and a ice making
sequence will start automatically.
NOTE:
After the toggle switch is moved to the ICE
position, opening the curtain switch will interrupt the
sanitizing sequence. The sequence will resume from
the point of interruption when the curtain switch
closes.
