SANITIZING PROCEDURE
Use sanitizer to remove algae or slime. Do not use it to remove lime scale or other mineral deposits.
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.
!Warning
Disconnect electric power to the ice machine (and dispenser if applicable) at the electric switch box before proceeding.
Step 2 Refer to Removal of Parts For Cleaning/ Sanitizing and remove ice machine parts.
Step 3 Mix a solution of water and sanitizer.
Solution Type | Water | Mixed With |
Sanitizer | 4 gal. (15 l) | 3 oz (90 ml) sanitizer |
Step 4 Use the sanitizing solution and a sponge or cloth to sanitize (wipe) all parts and interior surfaces of the ice machine. Sanitize the following areas:
A.Side walls
B.Base (area above water trough)
C.Evaporator plastic parts
D.Bin or dispenser
Step 5 Rinse all sanitized areas with clear water.
Step 6 Install the removed parts, restore power and place toggle switch in 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 7 Wait about two minutes or until water starts to flow over the evaporator.
Step 8 Add the proper amount of Manitowoc Ice Machine Sanitizer to the water trough by pouring between water curtain and evaporator.
Model | Amount of Sanitizer | |
S300/S320/S420 | 3 ounces (88 ml) | |
S450/S500/S600/S850/ | 5 ounces (148 ml) | |
S1000/S1200 | ||
| ||
S1400/S1600/S1800 | 9 ounces (266 ml) |
Step 9 The ice machine will automatically time out a ten minute sanitizing cycle, followed by six rinse cycles, and stop. The Clean light will turn off to indicate the Cleaning cycle is completed. This entire cycle lasts approximately 30 minutes.
When the sanitizing process stops, move the toggle switch to ICE position.
