knob is pointing to the “white dot”. The machine
is now working and the first cooling cycle can
begin.
5) The first freezing cycle will last about 35
minutes. During this time, make sure that the
plasticcurtainthatcoversthewaterspraysystem
hangs down loose and no excessive water is
passing through, make sure to eliminate
eventually noises and vibration sources.
6) After about 35 minutes of operation, the
first ice cubes harvest takes place.

CLEANING AND CARE
WARNING - Before proceeding with
anycleaning operationmakesurethat
the power line of the unit is discon-
nected.
WATER RESERVOIR AND STORAGE
BIN LINER
All commercial units that make or contain edible
produces, require a frequent throught sanitation
of all their parts that are in contact with the
produces.
It is recommendable, therefore, to perform the
cleaninganddisinfectingoperationonceaweek
as per the following indications.
- Remove all ice cubes deposited in ice storage
bin if there are any.
-Remove the front lower panel by pulling it
from its upper edge and locate the water
reservoir.
Place one hand under the reservoir in order to
hold it and with the other grab the hooked front
edge.
- Slightly move the reservoir upward until it is
loose, than lower and tilt it a bit while
drawing out (try to avoid the pump body in
doing this).
- Make this reservoir empty and then place it
back in the unit.
- In a separate plastic pan, prepare a solution
with our rinsing - disinfectant P/N 264000 02.
- Pour the prepared solution into the storage bin
compartment than wipe clean its interior,
meanwhile the solution flows down into the
reservoir.
- Connectthepowerline andputinoperationthe
unitforfewminutes.Thebleachingsolution will
be circulated by the pump through the water
pipes and nozzles.
- Disconnect the power line, remove again the
plasticreservoir,makeitemptythenre-fititinits
place.
-Pourthroughthe funnel the necessary quantity
of new fresh water until the maximum water
level in the water reservoir is reached.
- The until is now sanitized and can resume
normal operations.
PUMP INLET SCREEN
While the water reservoir is removed, it is
recommendable to clean the water pump inlet
screen.
Pull it down with gentle pressure and wash it
clean under a stream of tap water. Once the
screen is properly cleaned reposition it in its
original place on the pump body.

Page 9
Page 9
AIR COOLED CONDENSER
It is very important to clean the condenser
regularly. A dirty or blocked condenser, will
drastically reduce ice production.
Use a vacuum cleaner to remove dust from the
front of the condenser.
CABINET EXTERIOR
Clean with warm water. Do not apply wax.
Note. When cleaning the floor in the imme-
diate front the unit, try to do not move much
dust that could be easily sucked inside the
units through the panel louvers.
Eventually,forfewseconds,youcanplace
in front of the louvers a piece of paper or
cardboard to prevent that the brushed
dust panetrates into the machine
compartment.

WATER CIRCUIT

∑
PRINCIPLE OF OPERATION
IntheSD10,the water to make iceiscontinually
movedorcirculatedbyasmallelectricpumpthat
sprays the water under gentle pressure through
the two spray jets into the eight inverted cube
molds.
Part of the water that hits the cold refrigerated
molds freezes, building gradually into full ice
cubes bell shaped.
FREEZING CYCLE (How it works)
Thehotgasrefrigerant,pumpedanddischarged
bythecompressor,passesthroughthecondenser
wherethefanblowingaircausesthechangingof
it into liquid.
The liquid line takes the refrigerant from the
condensertothecapillarytube.Duringthetravel
intothecapillarytube,theliquidrefrigerantlooses
gradually its temperature and pressure, then it
reaches the evaporator coils.
Because of the water sprayed against the
evaporator molds and coil, the liquid refrigerant
senses the heat of this water and starts boiling,
changing, as a consequence, from liquid into
vapor state.
The vapor refrigerant is sucked back to the
compressor through the suction line.
Thefreezingcycleiscontrolledbyatemperature
controlwhichdeterminesaswellthelengthofthe
cycle and consequently the size of the ice cube.
Duringthisphase,thecontactpointofthetempe-
rature control maintains closed the circuit of the
water pump which constantly sprays the water
under the evaporator mold cups up to the point
that the ice cubes reach their full size.
HARVEST CYCLE (How it works)
As soon as the temperature control senses the
temperature in the evaporator corresponding to
thefullsizecubes,thecontactmovestoclosethe
circuitoftheHotGasValveCoilandconsequently
to open the circuit of the water pump which
momentarily stops.
The hot gas refrigerant discharged by the
compressor is now diverted through the opened
hot gas valve to the evaporator coil.
The hot gas circulares through the evaporator
coil raising the temperature around the cube
cups sufficiently to release the ice cubes.
The released ice cubes drop by gravity into the
storage bin.
The temperature control bulb, due to the warm
temperature in the evaporator moves again the
contact de-energizing the hot gas valve and
energizing the water circulating pump starting a
new freezing cycle.

SERVICEMAN’S INFORMATIONS
GENERAL
Models SD 10 Ice Cube Makers have been
designed for little service and maintenance
requirements.
Average head pressure is 10 atm at the start-up
of the freezing cycle at 21°C ambient tem-
perature.
It gradually pulls down to 7 atm at the end of the
cycle.
Suction pressure at the start-up of the freezing
cycle will be around 3 atm then it pulls down
gradually to approximately 0 atm at the end of
freezing cycle.
