MAINTENANCE AND CLEANING INSTRUCTIONS
A.
GENERAL
The periods and the procedures for maintenance
and cleaning are given as guides and are not to
be construed as absolute or invariable.
Cleaning, especially, will vary depending upon
local water and ambient conditions and the ice
volume produced; and, each icemaker must be
maintened individually, in accordance with its
particular location requirements.
B.
ICEMAKER
The following maintenance should be scheduled
at least two times per year on these icemakers.
1.
Check and clean the water line strainer.
2.
Check that the icemaker is levelled in side
to side and in front to rear directions.
3.
Clean the water system, the evaporator, the
bin and spray platen using a solution of
SCOTSMAN Ice Machine Cleaner.
Refer to procedure C cleaning instructions and
after cleaning will indicate frequency and proce-
dure to be followed in local areas.
NOTE. Cleaning requirements vary according
to the local water conditions and individual
user operation. Continuous check of the clarity
of ice cubes and visual inspection of the
water spraying parts before and after cleaning
will indicate frequency and procedure to be
followed in local areas.
4.
With the ice machine and fan motor OFF on
air cooled models, clean condenser using vacuum
cleaner, whisk broom or non metallic brush.
5.
Check for water leaks and tighten drain line
connections. Pour water down bin drain line to be
sure that drain line is open and clear.
6.
Check size, condition and texture of ice
cubes. Perform adjustment of DIP SWITCH keys
as required.
7.
Check the ice level control sensor to test
shut-off.
Put a showelfull of ice cubes in contact with the
control sensor for at least one minute.
This should cause the ice maker to shut off and
the light up of the 3rd RED LED.
IMPORTANT. Perform the above check
only at the end of harvest cycle or at the
beginning of freezing cycle in order to do
not cause to the unit to make a double
freezing cycle.
Within few seconds after the removal of the
showelfull of ice from the sensing probe, the
icemaker restarts in freezing cycle.
NOTE. The RANGE OF THE ICE LEVEL
CONTROL SENSOR can be adjusted as
shown on table D of PRINCIPLE OF
OPERATION; its cut out setting remains
however at +2 ° C (35 ° F).
8.
Check for refrigerant leaks.
