INTERIOR CLEANING AND SANITIZING

GENERAL

Perform an In Place Cleaning/Sanitizing procedure monthly and a Cleaning/Sanitizing procedure every

12 months for efficient operation. If the ice machine requires more frequent cleaning and sanitizing, consult a qualified service company to test the water quality and recommend appropriate water treatment. An extremely dirty ice machine must be taken apart for cleaning and sanitizing.

CAUTION

Damage to the ice machine evaporator caused by incorrect chemical usage is not covered by the warranty. Use Manitowoc Ice Machine Cleaner (part number 000000084) and Sanitizer (part number 94-0565-3) only.

IN PLACE CLEANING/SANITIZING PROCEDURE

This procedure allows monthly in place cleaning of all surfaces that come in contact with the water system. The ice machine requires disassembly and cleaning/sanitizing a minimum of once every 12 months. The quality of your potable water supply may require more frequent cleaning intervals.

Use ice machine cleaner to remove lime scale or other mineral deposits. Ice machine sanitizer disinfects and removes algae and slime.

WARNING

Follow all labels and warnings on cleaner and sanitizer bottles.

NOTE: All ice must be removed from the bin.

Step 1 Prepare 4 oz (1/2 cup) of undiluted Manitowoc Ice Machine Cleaner (part number 000000084 only) in a container that will fit easily under the lifted water shutters.
