Maintenance & Cleaning (cont.)
5. Choose between the options.
PREVENTATIVE MAINT.: Shorter cycles; use between
bi-annual maintenance.
STANDARD: Normal cycle times; use when performing regular
bi-annual maintenance.
HEAVY: Longer cycle times; use when heavy scaling on parts
is obvious.
6. When "Would you like the unit to start making ice once
descaling and/or sanitizing is complete?" appears,
press NO.
7. Wait for the ice machine to run through the PRE-CLEANING
sequence (FILL, PUMP, DRAIN, and HARVEST). If there is enough
water in the sump at the start of CLEAN, it will go through
a DRAIN sequence before FILL. The compressor will start
during the HARVEST sequence to ensure there is no ice on
the evaporator and will shut off before the cleaning sequence
continues.
8. When ADD CLEANER appears, open the water curtain and
pour 10 oz (296 mL) of TRUE ice machine descaler between
the evaporator and the damper.
9. After adding descaler, press OK. The display will then show the
sequence status.
NOTICE ›
The sequence will not proceed from this point
unless OK is pressed after adding the descaler.
10. Wait for the ice machine to complete the cleaning cycle and
return to the home screen.
11. Prepare a solution of 10 fl oz (296 mL) TRUE ice machine
descaler to 1 gal (3.8 L) of warm water.
NOTICE ›
In cases where scale build up is particularly
heavy, substitute equal amounts ice machine descaler and
warm water.
