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,
by using the SIMAG technical service.
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, evaporator, bin
and spray jets using a solution of 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 taking
care to do not damage both the condenser and
ambient temperature sensors.
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 the evaporator
thermostat or cube size control by turning its
adjusting screw clockwise for a thicker ice cube
and counterclockwise for a thiner one.
7.
Check the bin thermostat to test shut-off.
Put a handfull of ice cubes in contact with its bulb.
This should cause the ice maker to shut off within
20÷30", but only at the end of the freezing cycle!
NOTE. Perform the above check only at the
beginning of the harvest cycle as, during the
freezing cycle the bin thermostat contacts
are bypassed by the front microswitch of the
timer.
When remove the ice cubes from its sensing
bulb the unit will restart after few seconds from
the defrost cycle assuring the filling up of the
water tank.
NOTE. It is possible to adjust the setting
temperature of the bin thermostat by slightly
turning its adjusting screw.
8.
Check for refrigerant leaks.
C.
CLEAN - REPLACE OF AIR
CONDENSER FILTER
1. Withdraw the air filter from the front through
the opening of the front panel.
2. Blow pressurised air on the opposite direction
of the condenser air flow so to remove the
dust accumulated.
3. If pressurised air is not available, use tap
water always in the counter flow air diretcion.
Once cleaned shake it so to remove most of
the accumulated water, then dry it using an
hair dryer.
NOTE. In case the air filter strainer is
damaged replace it with a new one.
4. Install it again by pushing it through the front
panel opening.
D. CLEANING INSTRUCTIONS OF WATER
SYSTEM
1.
Remove the front and the top panels to gain
access either to the control box and to the
evaporator.
