7. See data plate on the rear side of the unit
and check that local main voltage corresponds
with the voltage specified on it.
CAUTION.Incorrect voltage supplied to
the icemaker will void your parts
replacement program.
8. Remove the manufacturer’s registration
card from the inside of the User Manual and fill-
in all parts including: Model and Serial Number
taken from the data plate.
Forward the completed self-addressed
registration card to the factory.
C. LOCATION AND LEVELLING
WARNING. This Ice Cuber is designed for
indoorinstallationonly.Extendedperiods
of operation at temperatures exceeding
the following limitations will constitute
misuse under the terms of the
Manufacturer’s Limited Warranty
resulting in LOSS of warranty coverage.
1. Position the unit in the selected permanent
location.
Criteria for selection of location include:
a) Minimum room temperature 10°C (50°F)
and maximum room temperature 40°C (100°F).
b) Water inlet temperatures: minimum 5°C
(40°F) and maximum 35°C (90°F).
c) Well ventilated location for air cooled
models. Clean the air cooled condenser at
frequent intervals.
d) Service access: adequate space must
be left for all service connections through the rear
of the ice maker. A minimum clearance of 15 cm
(6") must be left at the sides of the unit for routing
cooling air drawn into and exhausted out of the
compartment to maintain proper condensing
operation of air cooled models.
NOTE.
With the unit in “built-in” conditions,
the ice production is gradually reduced in
respect to the levels shown in the graph, up
to a maximum of 10% at room temperatures
higher than 32
°
C.
The daily ice-making capacity is directly
related to the condenser air inlet temperatu-
re,watertemperatureandageofthemachine.
To keep your CUBER at peak performance
levels, periodic maintenance checks must
be carried out as indicated on Cleaning
Section of this manual.
2. Level the unit in both the left to right and
front to rear directions.

D. ELECTRICAL CONNECTIONS
See data plate for current requirements to
determine wire size to be used on electrical
connections. All icemakers require a solid earth
wire.
The ice machines are supplied from the factory
completely pre-wired and require only electrical
power connections to wire cord provided on the
back of the unit.
Make sure that the ice machine is connected to
its own circuit and individually fused (see data
plate for fuse size).
The maximum allowable voltage variation should
not exceed -10% and +10% of the data plate
rating. Low voltage can cause faulty functioning
and may be responsible for serious damage to
the overload switch and motor windings.
NOTE.
All external wiring should conform to
national, state and local standards and
regulations.
Check voltage on the line and the ice maker’s
data plate before connecting the unit.
E. WATER SUPPLY AND DRAIN
CONNECTIONS
General
When choosing the water supply for the ice cuber
consideration should be given to:
a) Length of run
b) Water clarity and purity
c) Adequate water supply pressure
Sincewateristhemostimportantsingleingredient
in producting ice you cannot emphasize too
much the three items listed above.
Low water pressure, below 1 bar may cause
malfunction of the ice maker unit.
Water containing excessive minerals will tend to
produce cloudy coloured ice cubes, plus scale
built-up on parts of the water system.
Water supply
Connect the 3/4" male fitting of the solenoid
waterinlet valve,using theflexible hosesupplied,
tothe cold water supply line with regularplumbing
fitting and a shut-off valve installed in an
accessible position between the water supply
line and the unit.
Water supply - Water cooled models
(65-90)
The water cooled versions of series 65 and 90
require two separate inlet water supplies, one for
the water sprayed for making the ice cubes and
the other for the water cooled condenser.
Connect the 3/4" male fitting of the water
regulating valve using the flexible hose supplied
with the unit to the cold water supply line with
regular plumbing fitting and a shut-off valve
installed in an accessible position between the
water supply line and the unit.
Water drain
The recommended drain tube is a plastic or
flexible tube with 18 mm (3/4") I.D. runs to an
open trapped and vented drain. When the drain
is a long run, allow 3 cm pitch per meter (1/4"
pitch per foot).
A vertical open vent, at the unit drain connection,
is also required for proper sump drainage.
Water drain - Water cooled models
The water drain line from the condenser, on
water cooled versions, is internally connected
with the drain fitting of the unit.
It is strongly recommended therefore to install a
vertical open vent on unit drain line high point to
ensure good draining and to direct the drain line
to a trapped and vented floor drain receptacle.
This to make sure of the proper flow of the
drained water as, in case of poor drainage, the
water ranning out from the condenser may
inopportunely flow, through the unit drain tubing,
into the ice storage bin.
NOTE.
The water supply and the water drain
must be installed to conform with the local
code. In some case a licensed plumber and/
or a plumbing permit is required.

F. FINAL CHECK LIST
1. Is the unit in a room where ambient
temperatures are within a minimum of 10°C
(50°F) even in winter months?
2. Is there at least a 15 cm (6") clearance
around the unit for proper air circulation?
3. Is the unit level? (IMPORTANT)
4. Have all the electrical and plumbing
connections been made, and is the water supply

completed the plumbing and electrical
connections,performthefollowing“Start-up” pro-
cedure.
20-30-40
A. Remove the unit front panel and locate the
cleaning switch on the control box.
B. Set the cleaning switch in the cleaning
position (II). This will close the electrical circuit to
the water inlet valve and to the hot gas valve.
C. Switch ON the power line disconnect
switch. Unit will start up in water filling phase
mode.
During this phase the components energized
are:
WATER INLET SOLENOID VALVE
HOT GAS SOLENOID VALVE
The Water pump and the Fan motor are also in
operation.
D. Let unit stay in water filling phase mode for
about three/four minutes till water is coming out
from the drain hose, then move the cleaning
switch to the operation position (I).
50-65-90
A. Remove the unit front panel and locate the
timer shaft on the control box.
B. Check that master and the compressor
switch located on the lower left hand side of the
control box are both in the OFF position.
C. Rotate the timer shaft protruding through
the front of the control box clockwise, until and
audible click is heard indicating that the actuator
arm of the microswitch has dropped into the cam
slot (Fig. A).
D. Set the master switch to the ON position.
The compressor switch must stay in the OFF
position. This will close the electrical circuit to the
water inlet valve and to the hot gas valve.
E. Switch ON the power line disconnect
switch. Unit will start up in defrost cycle mode.
During this cycle the components energized are:
WATER INLET SOLENOID VALVE
HOT GAS SOLENOID VALVE
TIMER MOTOR
F. After completion of harvest cycle (about
three minutes) move the compressor switch to
ON position.
NOTE.
During the defrost cycle, the water
inlet solenoid valve is energized. The water
flows through the valve to the back side of the
evaporator platen and then down to fill up the
icemaker sump tank for the next freezing
cycle.
OPERATIONAL CHECKS
A. The unit now starts its first freezing cycle
with the following components in operation:
COMPRESSOR
WATER PUMP
FAN MOTOR in air cooled version
B. Check to see through the ice discharge
opening that the spray system is correctly seated
and that the water jets uniformely reach the
interior of the inverted cup molds; also make sure
that the plastic curtain is hanging freely and there
is not excessive water spilling through it.
C. The ice making process takes place
thereby, with the water sprayed into the molds
that gets gradually refrigerated by the heat
exchanged with the refrigerant flowing into the
evaporator serpentine.
D. On units 20-30-40 when the evaporator
temperature reaches a preset value the
evaporator thermostat or cube size control
changes its contacts; the freezing cycle ends
and starts the defrost or harvest cycle.
E. On units 50-65-90 the time clock does not
rotate at the end of the harvest cycle. It starts
later when the cube size thermostat control bulb
(pig tail) located on the evaporator coil reaches a
temperature of approx. -15°C (5°F).
Page 14

Freezing time will range between 20 and 22
minutes in a 21°C ambient temperature, longer if
above this temperature and shorter if below. The
average complete cycle time is between 23 and
25 minutes.
F. Check, during the first defrost/harvest
cycle, that the incoming water flows correctly into
the sump reservoir in order to re-fill it and the
surplus overflows through the overflow drain tube.
G. Check the texture of ice cubes just
released.Rightsizemusthavea smalldepression
(about 5-6 mm) in their crown.
If not, wait for the second defrost/harvest cycle
before performing any adjustment.
H. If required on model 21, 31 and 40, the
length of the freezing cycle can be modified by
turning the knob of the cube size control or
evaporator thermostat located in front of the
control box until the desired size is achieved.
•If the temperatu-
re of the room in
which the machine
is place is below
20°C,thecubeswill
tend to be partly
hollowed out (see
fig. on right).
•If, on the other
hand, the room
temperature is
above 30°C the
cubes produced
will have a jagged
rim of ice around
the crown.
If it is thought necessary, the above situations
can be rectified by, in the first case, turning the
control knob (as little or as much as is required)
clockwise and, in the second case, turning the
knob to the right counterclockwise.
It should, however, be remembered that if the
room temperature returns later to the 20 ÷30°C
range, the knob indicator must once again be
turned to point to the dot (see fig. below).
If the ice cubes are shallow and cloudy, it is
possible that the ice maker runs short of water
during the end of the freezing cycle or, the quality
of the supplied water requires the use of an
appropriate water filter or conditioner.
I. At the end of the defrost or harvest cycle
hold a handful of ice cubes against the bulb of the
storage bin thermostat; the icemaker switch OFF
in about one-two minutes.
Take out the ice from the storage bin thermostat.
The ice maker should restart automatically in
three-four minutes.
NOTE.
The bin thermostat is factory set at
1
°
C (35
°
F) OUT and 4
°
C (39
°
F) IN.
K. Re-fit the unit front panel then instruct the
owner/user on the general operation of the ice
machine and about the cleaning and care it
requires.

PRINCIPLE OF OPERATION
How it works
In the ice makers the water used to make the ice
is kept constantly in circulation by a water pump
which primes it to the spray system nozzles from
where it is diverted into the inverted cup molds of
the evaporator (Fig. A).
A small quantity of the sprayed water freezes into
ice; the rest of it cascades by gravity into the
sump assembly below for recirculation.
FREEZING CYCLE (Fig. B)
The hot gas refrigerant discharged out from the
compressorreachesthecondenserwhere,being
cooled down, condenses into liquid. Flowing into
the liquid line it passes through the drier/filter,
then it goes all the way through the capillary tube
where it looses its pressure.
Next the refrigerant enters into the evaporator
serpentine (which has a larger diameter then the
capillary tube) and starts to boil off; this reaction
is emphasized by the heat transferred by the
sprayed water.
The refrigerant then increases in volume and
changes entirely into vapor.
The vapor refrigerant then passes through the
suction accumulator (used to prevent that any
small amount of liquid refrigerant may reach the
compressor) and through the suction line. In both
theaccumulatorand the suctionline itexchanges
heat with the refrigerant flowing into the capillary
tube (warmer), before to be sucked in the
compressor and to be recirculated as hot
compressed refrigerant gas.
The freezing cycle on 20-30-40 is controlled by
only the evaporator thermostat which has its bulb
in contact with the evaporator serpentine while in
50-65-90 there is an second phase controlled by
a timer.
The electrical components in operation during
the freezing cycle are:
COMPRESSOR
WATER PUMP
FAN MOTOR (in air cooled version)
On 20-30-40 air cooled versions the refrigerant
head pressure is gradually reduced from a value
of approx. 11 bars (155 psig) at the beginning of
the freezing cycle with the unit at 21°C (70°F)
ambient temperature, to a minimun value of
approx. 7 bars (100 psig) just at the end of the
freezing cycle few seconds before the starting of
the defrost cycle.
On 50-65-90 air cooled versions the refrigerant
headpressureiskeptbetweentwopre-setvalues
(10÷8,5 bar - 140÷120 psig) with the unit a 21°C
(70°F) ambient temperature.
The declining of the pressure is relied to the
reduction of the evaporating pressure, caused
by the progressive growth of the ice thickness
into the inverted cup molds and to the flow of air
drown through the air cooled condenser by the
fan motor. The above values are in relation as
well to the ambient temperature of the ice maker
site and they are subject to rise with the increase
of this temperature.
On 20-30-40-50 water cooled versions the
refrigerant head pressure ranges between 8.5
and 10 bars (120÷140 psig) being controlled by
an automatic hi pressure control that energizes a
water solenoid valve located on the water line to
the condenser, which rates the cooling water to
the condenser.
On 65-90 water cooled versions the head
pressure is constant at 9.5 bar (135 psig)
controlled by a water regulating valve.
Atstartingoffreezingcyclethe refrigerantsuction
or lo-pressure lowers rapidly to 1.0 bar - 14 psig
then it declines gradually - in relation with the
growing of the ice thickness - to reach, at the end
of the cycle, approx. 0÷0.1 bar - 0÷1.5 psig on
the models 20, 30 and 40 and 0.2÷0.3 bar (3÷4
psig) on models 50, 65 and 90 with the cubes fully
formed in the cup molds.
The total length of the freezing cycle ranges from
23 to 25 minutes.
DEFROST OR HARVEST CYCLE (Fig. D)
On 20-30-40 the temperature of the evaporator
thermostat, in contact with the evaporator
serpentine, drops to a pre-set value it changes its
electrical contacts energizing the herebelow
shown components.
(On 50-65-90 when the timer microswitch drops
down into the lower portion of the cam it changes
its electrical contacts energizing the same
components).
COMPRESSOR
WATER INLET SOLENOID VALVE
HOT GAS SOLENOID VALVE
The incoming water, passing through the water
inlet valve and the flow control, runs over the
evaporator platen and then flows by gravity
through the dribbler holes down into the sump/
reservoir (Fig. C).
The water filling the sump/reservoir forces part of
the surplus water from the previous freezing
cycle to go out to the waste through the overflow
pipe. This overflow limits the level of the sump
water which will be used to produce the next
batch of ice cubes.
Meanwhile the refrigerant, as hot gas discharged
from the compressor, flows through the hot gas
valve directly into the evaporator serpentine by-
passing the condenser.
The hot gas circulating into the serpentine of the
evaporator warms up the copper molds causing
the harvest of the ice cubes. The ice cubes,
released from the cups, drop by gravity onto a
slanted cube chute, then through a curtained
opening they fall into the storage bin.
Page 16

On 20-30-40 when the temperature of the
evaporator thermostat bulb reaches the value of
+3÷4°C their electrical contacts move back to the
previous position activating a new freezing cycle
and deenergizing both the hot gas and the water
inlet valves (closed).
On 50-65-90 as soon as the timer microswitch
completes the bottom part of the cam and it is
pushed again, it activates a new freezing cycle
deenergizing both the hot gas and the water inlet
valves (closed).
NOTE. On models 20, 30 and 40 the length
of the defrost/harvest cycle (not adjustable)
changes according to the ambient tempe-
rature (shorter for hi ambient temperature
and longer for low one).
COMPONENTS DESCRIPTION
A. WATER PUMP
The water pump operates continually throughout
the freezing cycle. The pump primes the water
from the sump to the spray system and through
the spray nozzles sprays it into the inverted cup
molds to be frozen into crystal clear ice cubes.
B. WATER INLET SOLENOID VALVE -
3/4 MALE FITTING
The water inlet solenoid valve is energized only
during the defrost cycle.
When energized it allows a metered amount of
incoming water to flow over the evaporator cavity
to assist the hot gas in defrosting the ice cubes.
The water running over the evaporator cavity
drops by gravity, through the dribbler holes of the
platen, into the sump reservoir.
On 20-30-40-50 water cooled versions the water
inlet solenoid valve has one inlet and two outlets
with two separate solenoids energized the first
(ice productioon) by the contacts 3-2 of the
evaporator thermostat and the second (water
cooled condenser) by a specific hi pressure
control.
C. HOT GAS SOLENOID VALVE
The hot gas solenoid valve consists basically in
two parts: the valve body and the valve coil.
During the defrost cycle the hot gas valve coil is
activated so to attract the hot gas valve piston in
order to give way to the hot gas discharged from
compressor to flow directly into the evaporator
serpentine to defrost the formed ice cubes.
D. BIN THERMOSTAT
The bin thermostat control body is located in the
front of control box behind the front panel.
The thermostat sensing tube is located into a
bulb holder on the side wall of the ice storage bin
where it automatically shuts the icemaker OFF
when in contact with the ice and re-starts the
icemaker when the ice is removed. Factory
settings are 1°C (35°F) OUT and 4°C (39°F) IN.
E. CUBE SIZE CONTROL (EVAPORATOR
THERMOSTAT)
20-30-40
The cube size control (evaporator thermostat)
body is located in the control box behind the front
panel; it’s basically a reverse acting temperature
control which closes the contacts 3-2 when its
temperature decreases and closes the opposite
contacts 3-4 when the temperature rises.
The thermostat sensing bulb is located into a
plastic tube (bulb holder) secured by two clips
directly to the evaporator serpentine.
This control determines the length of the freezing
cycle and correspondingly the size of the cubes.
A lower setting will produce a larger cube
(oversize) while a higher setting a smaller cuber
(shallow size).
When closed on contacts 3-2 it activates the
defrost or harvest cycle components.
The cube size control is set up in the factory
(knob in the black dot position) and doesn't
require any adjustment when the ambient
temperature remains between 20 and 30°C
(70 and 90°F).
50-65-90
The evaporator thermostat with its sensing bulb
intimately in contact with the regrigerant outlet
tube from the evaporator senses the evaporating
refrigerant temperature (which declines in the
course of the freezing cycle) and when this one
reaches the pre-set value, it switches its contacts
from 3-4 to 3-2 to activate the finishing cycle (2nd
phase)whichhasa pre-setextensiondetermined
by the large diameter lobe of the timer cam.
F. FAN MOTOR (Air cooled version)
The fan motor on 20-30-40 is electrically
connected in parallel to the water pump and it
operates continuously only during the freezing
cycle keeping the proper head pressure by
circulating air through the condenser fins.
On 50-65-95 the operation of fan motor is
controlled by a fan pressure control adjusted at
preset values.
G. COMPRESSOR
The hermetic compressor is the heart of the
refrigerant system and it is used to circulate and
retrieve the refrigerant throughout the entire
system. It compresses the low pressure
refrigerant vapor causing its temperature to rise
and become high pressure hot vapor (hot gas)
which is then released through the discharge
valve.
H. WATER SPRAY SYSTEM
Through its nozzles it sprays the water in each
individual cup to be frozen into ice.
I.
SAFETY HI TEMPERATURE THERMOSTAT
Located in the control box it is a manual reset
switchthattrips OFF the operationofthe machine
when its bulb (located on the liquid line just
before the drier) reaches the temperature of
70°C (158°F).
Page 17

Page 18
J. CLEANING SWITCH (only 20-30-40)
Located on the bottom left side of the control box
is used to energize the water inlet and the hot gas
valves so to charge the water into the sump tank
of the machine.
K. HI PRESSURE CONTROL (Water cooled
version)
Used only on 20-30-40-50 water cooled versions
it operates to keep between 8.5 and 10 bars (120
÷140 psig) the hi-side or discharge pressure of
the refrigerant system by energizing the coil of
the water inlet solenoid valve that control the
cooling water flow to the condenser.
L. TIMER (only 50-65-90)
Equippedwith two microswitcheswhich plungers
ride one timer cam, the timer is located inside the
control box.
The function of the timer begins when activated
by the cube size control (evap. thermostat).
The large diameter lobe of its cam determines
the length of the 2nd portion of the freezing cycle,
while the cam small diameter lobe, determines
the time cycle for the harvest sequence.
The timer cam can be adjusted to vary the defrost
time as required.
WARNING. Never set the defrost time for
longer than 4 minutes as this will
jeopardize the compressor motor
windings.
It goes without saying that an extension of the
defrostperiodwilldirectlyreducethetimedportion
of the freezing cycle and viceversa.
Consequently any variation made at the timer
camsettingrequiresa compensationadjustment,
very fine and very accurate, of the evaporator
thermostat.
M. MASTER SWITCH (only 50-65-90)
Fitted in the control box the master switch has to
be used to start-up and to stop the ice maker
operation.
N. COMPRESSOR SWITCH (only 50-65-90)
Locatedinthe controlboxis usedto de-energized
the compressor during the cleaning.
O. FAN PRESSURE CONTROL
(only 50-65-90)
Used on air cooled ice makers to maintain the
head pressure within the preset values.
P. WATER REGULATING VALVE
(only 65-90 Water cooled version only)
This valve controls the head pressure in the
refrigerant system by regulating the flow of water
going to the condenser.
As pressure increases, the water regulating val-
ve opens to increase the flow of cooling water.
Q. CONTACTOR (65-90 only)
It operates in order to close or open the electrical
circuit to the compressor.
