MAINTENANCE
REGULAR BASIS
(or as required)
Cleaning of the ice maker is recommended on a regular basis not only for sanitary reasons, but also to maintain
the performance of the unit. Build-up of lime and scale can hinder ice making production rates and interfere with
proper dispensing of the ice. See Cleaning Instructions for the recommended procedure.
EVERY THREE MONTHS
(or as required)
It is recommended that the air inlet filter be cleaned every three (3) months or sooner depending on the operat-
ing environment for proper refrigeration system performance. On an air-cooled unit, also check that the con-
denser is free of dirt/foreign material that could cause air flow blockage. Consult the Maintenance/Adjustment
Procedures section for cleaning these items.
PERIODICALLY
(or as required)
Check the vending area sink for proper water drainage. Remove any foreign material from the sink to prevent
drain blockage.
CLEANING INSTRUCTIONS
IMPORTANT: The ice maker should be cleaned at a minimum of three (3) month intervals or more
frequently, depending on local water conditions. The storage hopper interior should be cleaned once a
month.
CAUTION: Do not use metal scrapers, sharp objects or abrasives on the surface of the
storage hopper, as damage may result. Do not use solvents or other cleaning agents, as
they may attack the plastic surface. Use only the recommended chemicals and solutions for
both the ice maker and hopper.
Ice Maker Section
1. Open the hinged service door.
2. Put the “Stop/Run”switch in the “stop”position at the end of the harvest cycle.
WARNING: The unit is still plugged into the electrical power during ice maker section
cleaning. Therefore, do not reach into hopper, and do not contact exposed electrical wiring
or components.
3. Remove the ice drop cover from the evaporator and the storage hopper cover.
4. Seal the evaporator outlet with the plastic plug provided with the unit and replace the ice drop cover.
5. Remove cleaning fill plug and add four (4) ounces of Virginia Ice Machine Cleaner to the evaporator and
replace cleaning fill plug.
CAUTION: Virginia Ice Machine Cleaner is a mild acid, therefore, normal care should be
taken when using. Keep out of eyes and cuts. Read warnings on package before using. Do
not operate unit in the cleaning mode without the ice drop cover in place. There may be
some overflow of cleaning solution through the evaporator vent tube during the cleaning cycle.
