NOTE . The ICE LEVEL CONTROL
(INFRARED SYSTEM) is independent of the
temperature however, the reliability of its
detection can be affected by external light
radiations or by any sort of dirt and scale
sediment which may deposit directly on the
light source and on the receiver.
To prevent any possible ice maker
malfunction, it is advisable to locate the unit
where it can't be reached by any direct light
beam or light radiation and to follow the
instructions for the periodical cleaning of the
light sensor elements as detailed in the
MAINTENANCE AND CLEANING PROCE-
DURES.
NOTE. In the front of the PC Board is located
a small I/R Trimmer directly connected with
the optical Ice level control. By means of its
screw it is possible to modify the signal
received from the Ice Level control so to
overcame some problem caused by dirt and/
or low power supply.
When adjusted it is very important to check
for its correct operation using ice (NOT
HAND) to break the Infrared Beam. In case
the machine doesn't stop it means that the
new setting is too much powerfull and need to
be reduced always by means of the I/R Trimmer.
M. If previously installed, remove the refrigerant
service gauges and re-fit the unit service panels
previously removed.
N. Instruct the owner/user on the general
operation of the ice machine and about the
cleaning and care it requires.
