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 fill­in 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
indoor installation only. Extended periods
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 temperatu­re, water temperature and age of the machine.

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.

GENERAL INFORMATION
AND INSTALLATION

A. INTRODUCTION

These Cubers are quality designed, engineered
and manufactured.
Their ice making systems are thoroughly tested
providing the utmost in flexibility to fit the needs
of a particular user.
These ice makers have been engineered to our
own rigid safety and performence standards.

NOTE.

To retain the safety and performance
built into this icemaker, it is important that
installation and maintenance be conducted
in the manner outlined in this manual.

B. UNPACKING AND INSPECTION

1. Visually inspect the exterior of the packing
and skid. Any severe damage noted should be
reported to the delivering carrier and a concealed
damage claim form filled in subjet to inspection of
the contents with the carrier’s representative
present.

2. a) Cut and remove the plastic strip securing
the carton box to the skid.

b) Cut open the top of the carton and

remove the polystyre protection sheet.

c) Pull out the polystyre posts from the

corners and then remove the carton.

3. Remove the front and the rear panels of the
unit and inspect for any concealed damage.
Notify carrier of your claim for the concealed
damage as stated in step 1 above.

4. Open the bin door and remove all internal
support packing and masking tape.

5. Check that refrigerant lines do not rub
against or touch other lines or surfaces, and that
the fan blade moves freely.

6. Use clean damp cloth to wipe the surfaces
inside the storage bin and the outside of the
cabinet.

Page 2

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

Since water is the most important single ingredient
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
water inlet valve, using the flexible hose supplied,
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 supply - Water cooled models
(B75 - B90)

The water cooled versions of series 75 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
shut-off valve open?

5. Has the voltage been tested and checked
against the data plate rating?

6. Has the water supply pressure been
checked to ensure a water pressure of at least

9. Has the owner/user been given the User
Manual and been instructed on the importance of
periodic maintenance checks?

10. Has the Manufacturer’s registration card
been filled in properly? Check for correct model
and serial number against the serial plate and
mail the registration card to the factory.

11. Has the owner been given the name and
the phone number of the authorized Service
Agency serving him?

WARNING. This icemaker is not designed for outdoor installation and will not function in
ambient temperatures below 10°C (50°F) or above 40°C (100°F).
This icemaker will malfunction with water temperatures below 5°C (40°F) or above 35°C
(90°F).

OPERATING INSTRUCTIONS

START UP

After having correctly installed the ice maker and
completed the plumbing and electrical
connections, perform the following “Start-up”
procedure.

B20 - B40 - B45

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).

B75 - B90

A. Give power to the unit to start it up by
switching ON the power line main switch; the unit
will start automatically in defrost cycle with the
following components energized:

WATER INLET SOLENOID VALVE
HOT GAS VALVE
COMPRESSOR
ELECTRONIC TIMER

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 B20 - B40 - B45 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 models B75 - B90 freezing cycle is
completed through an electronic timer
energized by the evaporator thermostat. It
starts when the cube size thermostat/control
bulb (pig tail) located on the evaporator
serpentine reaches a temperature of approx.

-15°C (5°F)

.

On units

B75 - B90

the
additional Time (8') of the freezing cycle
starts when the cube size thermostat control
bulb (pig tail) located on the evaporator coil
reaches a temperature of approx. -15°C.
Freezing time will range between 20 and 22
minutes in a 21°C ambient temperature,
longer if above this temperature and shorter
if below.Then the unit goes directly into the
Defrost Cycle. 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.
