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. 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.
4. Check size, condition and texture of ice
cubes. Perform adjustment of cube size control
as required.
5. Check the bin thermostat to test shut-off.
Put a showelfull of ice cubes in contact with the
bin thermostat bulb for at least one minute.
This should cause the ice maker to shut off.
Within few seconds after the removal of the
ahowelfull of ice from bin thermostat bulb, the
icemaker restarts.
NOTE. Within minutes after the ice is removed
from the bulb holder tube, the sensing bulb
inside the tube will warm up and cause the
icemaker to restart. This control is factory set
and should not be reset until testing is
performed.
6. Check for refrigerant leaks.
NOTE. The new EC series, in the air cooled
version, are standard equipped with an air
condenser filter as well as a Cleaning
Reminder Board to remind to the end user
the need for the cleaning of the air filter or of
the water system (Red Alarm Light ON Steady
or Blinking rispectively with machine in
operation).
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 top panels to gain
access either to the control box and to the
evaporator.
2. Make sure that all ice cubes have been
released from their cups, then switch OFF the
machine at front master button switch.
3. Scoop out all the ice cubes stored into the
bin in order to prevent them from being
contaminated with the cleaning solution.
