DESCRIPTION

Main Features of the Machine

§ 18/8 stainless steel housing

§ Powerful speed reducer (24Kg./m. @ 7 rpm.)

§ Copper evaporator on precision bored tubing (HB 50)

§ Durable stainless steel auger with resilient coating

§ Ice drops out of the bottom of unit

§ Speed reducer in top part of the unit

§ Ecological refrigerant R404a

OPERATING PRINCIPLE

hole in the bottom of the trough, water flows into the bottom of the evaporator and floods it to the
same height as in the water trough. Water freezes upon contact with evaporator wall, and is
scraped off as ice by the vertical, rotating auger. Ice is carried upward until it passes through
discharge flap and falls into bin. When bin is full, automatic shut-off sensor (micro-switch on
discharge flap) switches off machine.

IMPORTANT!

MECHANICAL ICE LEVEL SENSOR should be installed. To prevent ice from compressing in
cold storage, we recommend transferring ice through a plastic tube (80­attached to its lower end the DISPERSION CONE which is PROVIDED WITH THE MACHINE in
all models.

Water quality = 500 ppm (240 Microhms/cm)

About ice production

IMPORTANT: Production figures have been obtained under the following conditions:

13

Water Quality: 550 ppm. total solids

ors. As shown,

IT IS IMPORTANT THAT WATER INTAKE TUBE IS NOT CLOSE TO ANY HEAT SOURCE.

• Ice production also decreases with improved water quality. (See graph for approximate

10152025303540

45

Room temperature

Water Temperature: 15°C
Ambient Temperature: 20°C
Ice production and quality is heavily dependent on the following:
a) Ambient temperature
b) Water temperature
c) Water quality
d) Level of water in evaporator
The following graph illustrates variations in production according to these fact
production decreases as water temperature increases.

THIS WILL AFFECT ICE PRODUCTION AND QUALITY.

• Ambient temperature should be taken 4cm away from the centre of the front grille

• Water temperature should be taken inside the water trough. Check that water line and filter do
not receive hot air from condenser + fan. If so, then re-direct water inlet line + filter to avoid hot
air current.

• Ice quality can be improved by lowering the position of the water trough. The trough is attached
to a panel with two screws. This panel has several slots, so that the trough can be moved up or
down as required.

• The trough may be lowered up to 80mm (IQ 550/1100). This will result in decrease of
production (see dotted line in graph below), but harder, drier ice.

• Water content in ice (obtained by straining ice) may be as much as 10%

production variations).

INSTALLATION

Recommended Placement of Unit

IMPORTANT!

with water temperature rangin
malfunctions should the machine run at temperatures below the recommended minimum. When
running above maximum recommended temperatures you can expect shorter compressor life
and decreased production.
Air-cooled units receive air input via front of machine and expel air through rear grille.
IMPORTANT!
If front and/or rear ventilation is inadequate, obstructed, or in close proximity to other heat
producing machinery, use of a water-cooled unit is strongly recommended.
The above mentioned also applies should unit be installed in an area where dust, smoke, or other
airborne pollutants may be present. Units—especially air-cooled ones—should not be installed in
kitchens. To facilitate access to condense
front of the machine. Ensure that flooring is firm and even.

Water and Drainage

Water quality influences ice hardness, flavour, and quality as well as condenser life.
Keep in mind the following points:
a) WATER IMPURITIES: Major impurities are eliminated by the two small wire mesh filters
provided and installed on either end of the water inlet hose. Filters should be cleaned/replaced
regularly depending on purity of water. For minor impurities we recommend installing a 5­filter such as the one provided with the unit: Part # ITV 207499. This filter will need to be replaced
only when machine stops due to insufficient water flow (filter is obstructed with impurities).

b) WATER WITH MORE THAN 500 PPM: Ice will be less hard and tend to adhere. Lime deposits
may impede proper function. In water-cooled models, condenser obstruction is likely. Installation
of a high quality water softener is recommended.

c) CHLORINATED WATER: In most cases the filter which is included in the machine should be
sufficient. However, if mains water smells or tastes of bleach, this indicates an excess of chlorine,
which may eventually corrode the stainless steel auger. A carbon filter will remove chlorine in
water (average filter life: 6 months), not included with machine. (Part # ITV 207509).

(NOTE: You may encounter water with ALL aforementioned properties.)

16

rating plate as well as on this manual's technical pages. Voltage fluctuations greater than 10%

d) PURIFIED WATER: A 10% reduction in overall production may occur.

Connecting Unit To Water Source

• Use 1.3 m. flexible tube (with the two filters attached) provided. NOTE: We advise using a
single faucet fixture.

• Water pressure should be between 0.7 and 6 Kgs/cm2. (10/85 Psi.)

• If water pressure exceeds these values, installation of appropriate corrective units will be
necessary.

• It is important that water tubing does not come close to or in contact with any heat sources or
heat generated by unit as this could decrease production.

Connecting Unit To Drain (Water -cooled Models)

• Drain must be located at least 150mm below machine level. Drain tube must have an inner
diameter of 30mm and a minimum gradient of 3 cm per metre.(3%)

Electrical connection

• Unit is provided with a 1.5 m cord and Schucko socket (except for models IQ550 and IQ1100).

• A switch and adequate fuses should be installed. Nominal voltage and intensity are indicated on

can cause problems or prevent machine from starting.

• Line to base of plug must have a minimum section=2.5 mm2 for models up to IQ 200 and 4
mm2 for other models.

• Be sure voltage indicated on rating plate corresponds to that of mains supply.

IMPORTANT!

Supply socket must be properly earthed. Be sure to check standard for country where appliance
is going to be installed.

Assembling the dispersion cone

This device spreads ice evenly so it does not pile up
beneath exit tube. Its position can be altered to
redirect ice, and hence prevent the “pyramid effect”.

17

should be switched off except for power display (green), indicating that power is on. Otherwise

OPERATION

Preliminary Checks

a) Is machine levelled?
b) Are voltage and frequency of mains supply the same as indicated on rating plate?
c) Is drainage system working properly?
d) Is air circulation and room temperature adequate? (Air-cooled models)

AMBIENT TEMPERATURE WATER TEMPERATURE

MAXIMUM 43° C 35° C
MINIMUM 5° C 5° C

e) Is water pressure adequate?

MAXIMUM 0.7 Kg/cm2
MINIMUM 6 Kg/cm2

ATENTION: Check that voltage and mains frequency is the same as in the rating plate.

Starting up

Once preliminary check has been completed (ventilation, connections, temperature, etc.),
proceed as follows:

1. Remove top cover of unit

2. Open faucet, make sure there are no leaks and check that water level is adequate.

4. Set switch to OFF position.

5. Connect unit.

6. Check for air bubbles in water supply tubing (water trough to evaporator)

IMPORTANT!
Be sure voltage and frequency of mains supply is as indicated on rating plate.

1. Set appliance switch to ON position. All elements should be working except for fan (air-cooled
machines) which will commence operation only when high pressure activates it. All pilot lights

check the troubleshooting section of this manual.

Pressure-controlled Valve on cooling water circuit

• The purpose of this valve is to control cooling water flow to the condenser, so as to maintain the
high pressure at 16.5 bar (232­temperature).

• If mains water temperature exceeds 32
temperature at exit will be higher.
ADJUSTMENT: High pressure (and water temperature) can be decreased by opening valve (turn
screw clockwise).

Fan pressostat (air–cooled models)

High pressure is controlled by starting and stopping fan, which provides airflow through
condenser. Differential is fixed. (1Kg/cm2 or 14 Psi.) Cut-off pressure should be 16 Kg/cm2 (228
Psi.) Low pressure values in circuit may cause gearbox malfunction due to excessive ice
production. Pressure values higher than 14 Kg/cm2 will diminish ice production and may shorten
compressor life. Pressure can be regulated by rotating screw on Pressure Control Valve
(clockwise to increase pressure). One full turn is equivalent to about 1.5 Kg/cm2.

NOTE: You will observe that after a certain period of functioning (the running-in period), low­pressure pressostats may need to be adjusted. This second adjustment will be final.

RUNNING-IN CHECK

It is essential to service the machine after about 10 working days, or earlier if any incident has
occurred.

CHECK:

• Water level

• Minimum high pressure (fan should stop at 35-37ºC, equivalent to 5.25 bar, 67.5 psi)

• By-pass opening at -21ºC ± 0,5ºC during the first few minutes after start-up

• Ice dispersion cone is spreading ice uniformly inside the bin.

• Refrigerant charge (when fan switches off, bubbles should appear at the sight glass, and

return line to the compressor should be covered in frost right up to the weld). If high-pressure
manometer is connected do not disconnect until you stop the machine and pressures have
stabilised. Check that a large amount of gas has not been lost in connecting/disconnecting
manometers, and use the shortest hoses you can find in H.P.

• Any gearbox oil leaks?

Newly installed electromechanical control devices will suffer variations in their adjustment caused
by the machine’s own functioning. Once a second adjustment of these devices is carried out, this
should be good for several years. It is recommended, however, to check these devices yearly,
this is best done between October to April.

SAFETY TRIP (CIRCUIT­DUE TO ONE OF THE FOLLOWING:

• Ambient temperature is below 5ºC

• Water temperature is below 5ºC

• Evaporation temperature is below -20ºC

• Cooling temperature below +30ºC

• Refrigerant charge slightly low

In the first three cases, so long as temperatures do not drop below 3ºC (machine limit), re­fan pressostat to 42ºC and check that by-pass opens at -21ºC. In the last two cases bypass will
open and close very often. Adjust bypass, fan pressostat and add refrigerant if necessary.

Gearbox current consumption should be between 1.9A (min) and 2.6A (peaks) with an average

2.2A. Safety trip will work at 2.4-2.6A and switch off the machine immediately.

If the machine is over 2 years old, also inspect the auger, bearings, and grease on bearings.

In case of excess current consumption, you can verify that the problem is in the gear­either physically detaching gearbox and motor from auger and checking current consumption, or
by removing only the brown wire which provides current to the compressor.

In order to avoid damage to the gear-box, the safety trip is very sensitively adjusted and may trip
easily. You may teach the end user to re-connect the machine (by inserting a pen/screwdriver
through the front grille blades). This is best done after a one hour pause.

Should the machine trip on a regular basis (more than once a week), the end user must get in
touch with the service department.
