USER MANUAL - FLAKE ICE MAKER
Many thanks for selecting our product and we wish you a long and problem free use for many years. In every complain or communication about the ice
machine with the manufacturer or the distributor indicate the model and serial number.
CAUTION: handle carefully to avoid damage to the refrigerating circuit.
CAUTION: this product uses HC refrigerant gas (hydrocarbons) which is therefore flammable. The R290 gas (propane) is present in the equipment according
to a load quantity that is lower than that prescribed by the regulations on flammable gases.
CAUTION: for installation in a kitchen, add the equipotential earth system.
CAUTION: during operation of the ice machine, pay attention to the moving mechanical parts.
CHECK AT DELIVERY
1) The packing is intact.
2) The delivered ice machine with the purchase order.
3) The ice machine is not damaged during transport and no parts are missing. In case of damages or missing parts, report immediately to the delivering
carrier or your supplier.
INSTALLATION PROCEDURE
1) Carefully read all the applicable national regulations for connection to the water supply network.
2) The ice machine must be installed in conformity with national installation regulations.
3) The ice machine is not suitable for outdoor use.
4) The ice machine is not suitable for installation in areas where jets of water may be used.
5) The ice machine must be installed only in places where operation and maintenance are performed by qualified personnel.
6) Only persons with knowledge and practical experience of the ice machine, in particular as regards safety and hygiene standards, should be allowed access
to the service area.
7) The ice machine is not designed for use by persons (including children) with reduced physical, sensorial or mental capacity, or with no experience or
knowledge, unless they are supervised or instructed in use of the equipment by a person responsible for their safety.
8) The weighted sound pressure level "A" is below 70 dB.
9) Remove the ice machine from its packing and place it in the desired position, ensuring that it is perfectly horizontal (feet are adjustable) and well away
from heat sources. Also the ambient must be ventilated.
10) The modular ice machine must be suitably fixed to prevent any instability.
11) Air inlets and outlets should be kept at least 20 cm from walls.
12) Ambient temperature must not be lower than 10°C or higher than 35°C for a satisfactory yield and to prevent freezing.
13) Power supply must be 230 V single phase - (1200/2500 400 V threephase N). The maximum voltage variation permitted is ±6%. It is advisable to protect
the main switch by means of a fuse.
14) An earth terminal is essential.
15) Drink water supply pressure must not be less than 1 bar (kPa) and not higher than 6 bar (600 kPa). Water temperature must be between 5°C and 20°C for
a satisfactory yield.
16) Should the room and/or the drinking water temperature fall below 10 °C, you may need the bin/evaporator thermostats to be adjusted by an authorised
installer for their proper functioning.
17) Drink water is supplied through a flexible hose (provided with the machine) which should be connected to the water mains by means of its 3/4" BSP
threaded connection. Only with drink water. When replacing the pipe, the gaskets should also be replaced. In the case of drinking water with a hardness
higher than 10 dH/ 18 C° fH and a conductivity of 300 μs/cm, we recommend using purified water for a smooth operation and a longer life of the machine.
18) The drain pipe must have a drop of at least 15%. If the drain is far from the ice machine use a larger diameter hose, ensuring that it is not twisted or kinked
at any point. Note, use an open vented drain.
19) If the power supply cable is damaged, it must be replaced by the manufacturer or its technical support service or in any case by a person with a similar
qualification, in order to prevent all risks.
20) For ice machines with three-phase power supply, ensure that the power supply network in the place of installation has a maximum line impedance value
of (0.255+J0.160) ohm.
21) A common trip circuit breaker must be provided incorporated in the power supply network.
ATTENTION: HIGH TEMPERATURES, WATER OR/AND AMBIENT, AND WATER WITH HIGH CONTENCE OF MINERALS CAN CAUSE
WET ICE.
STARTING UP:
After checking all the previous points:
1) Turn the water supply tap on.
2) Place the plug in the power socket with main switch. If the unit is only equipped with an electrical cord for power supply, the authorized service company
must connect the lead wires to an electrical plug that corresponds to the local electrical requirements or to a separate two poles disconnect switch with
opening between the contacts of minimum 3 millimeters, very close to the ice machine to be reached easily and promptly.
3) Turn on the main switch. The self-contained machines start immediately and the modular machines will start only after approximately 4 minutes
(temporized by the electronic board).
4) After stopping the machine operation by the main switch, wait at least 5 minutes before re-starting it again.
OPERATION: When starting the ice maker with in-built container, the following components are also started: the compressor, the fan, the motor, the reducer,
the auger and the water inlet. At this point the ice maker is ready for production. The water entering the ice maker, passes through the water level basin
completely flooding the evaporator and transforming into ice. The cycle is repeated continuously until the in-built container is filled with ice. After reaching
the condition of container full, the ice maker stops automatically by means of the container thermostat. After collecting the ice from the container, the ice
production resumes automatically always by means of the container thermostat.
When starting the modular ice maker, also the water inlet valve is started and after 3 minutes the gear motor, the auger and the water drain valve. The rinsing
with water from the evaporator is carried out for 1 minute and after 4 minutes also the compressor and the fan are started. At this point the ice maker starts the
productive phase. The water entering the ice maker, passes through the water level basin completely flooding the evaporator and transforming into ice. The
cycle is repeated continuously until the container is filled with ice. After reaching the condition of container full, the ice maker stops automatically by means of
the container sensor located in the ice falling tube. At this point the evaporator is emptied of the ice and the ice maker is emptied of the water. The sequence will
be as follows: when the container is full the compressor and the fan will stop, the water loading solenoid valve will turn off, the water draining solenoid valve
will be activated, the geared motor continues to operate, all for a fixed time of 1 minute. After one minute the geared motor stops and the draining solenoid
valve remains open. After collecting the ice, the ice maker automatically resumes ice production by means of the container sensor.
CAUTION: ICE IS FOR HUMAN CONSUMPTION, WASH YOUR HANDS BEFORE HANDLING, KEEP MACHINE BIN LID CLOSED AND
ENSURE REGULAR CLEANING OF ALL UTENSILS AND PARTS IN CONTACT WITH THE ICE.
MAINTENANCE AND CLEANING BY THE USER - DISCONNECTING POWER AND WATER SUPPLY.
1) The ice machine cannot be cleaned with a jet of water. Clean the ice storage bin, using a detergent diluted in warm water and rinse it with warm water.
2) Clean the bodywork with a soft damp cloth with a specific product.
ROUTINE MAINTENANCE (EVERY 6 MONTHS) - AUTHORIZED SERVICE ONLY
1) Clean the solenoid valve filter.
2) Clean the condenser wins with a soft brush each month.
3) Clean the ice production system and the storage bin.
4) In the event of lengthy idle periods clean all the parts of the ice machine.
