10.
Check eventually lose of refrigerant and check the aspiration line it is frost
until 20 cm from the compresor.
11.
If there are doubts about the refrigerant, connect the manomter with the
connectors Schrader and check that the working pressure it is the ones
indicated in page 24.
12.
Check that the fan turn freely.
13.
After taking out polyesthirene insulating from the outlet ice and the lid of
the crusher ice, check the state of the lubricant in the upper ball bearing. IF
there is water or they are partially solidify, check the ring O R and the ball
bearing located inside the ice crusher.

GENERAL
The periods and procedement of maintnenace and cleaning represent a guide
and has no to be consider as absolutes and invariables. The cleaning
depends a lot of the environmental conditions and the water used, as well as
the quantity of ice produced. Every unit has to have its own manteinance in
accordance with its place.
¾
CLEANING THE ICE MAKING EQUIPMENT
The following manteinance operations has to be done twice a year by the
supplier company of the equipment.
1.
Check and clean the filter grille located inside the connecter of water inlet..
2.
Check the unit is leveled in both direction. IF it isn’t leveled use the nuts to
level it.
3.
Take out the lid of the tank taking attention of not damaging the water level
sensors and pressing the float and clean its nozzles.
4.
Make sure the level of water in the tank is below the top and that it is
enough to guarantee a good performance.
5.
Clean the tank and the inner area of the evaporator using a descaling
product. Make references the cleaning instruction of the water circuit
mentioned in section “C”, after the cleaning it is possible to evaluate the
frequency and process the follow in the future depending on the place where
it is installe.
6.
Use a part of the descaling product in concentrate state to remove rest of
limes in the water level sensor in the tank.
7.
With the ice equipment stoppes in models cooled by air , clean the
condenser using a hoover or no metalic bruch taking attention not to damage
the room temperature sensors and hthe condenser.
8.
Check if there is leakages in the water circuit. Put water in the ice keeper to
assure the outlet pipe is free.
9.
Check the performance of the optical control of ice level putting one hand
between the electronic eyes to interrupt the infrared beam of light. In this way
the RED light switch off, it is located in the frontal side of the electronic board
and after some seconds all the unit stops and it switch on a YELLOW LIGHT.
The unit start up again automatically taking out the hand.
CLEANING AND MAINTENACE INSTRUCTIONS
NOTE: The need of cleaning depends on the water condition and use of the
equipment..
NOTE: The control of ice level by infrared it is composed by two light, the
transmitting and the receiver, between them the beam of light it is transmited
so as to the unit performance properly, it is necessary to clean once a month,
with a clean cloth
