1. INTRODUCTION
1.1. Warnings
This appliance should be installed by approved Technical Service Personnel.
This plug should be accessible at all times.
To reduce the risk of electrical shock, ALWAYS disconnect the machine BEFORE cleaning or
maintaining the equipment. Do not attempt to install, service, or modify this machine. Improper
use by other than specially trained technicians is extremely dangerous and may result in a fire
or electric shock.
This machine should not be placed outdoors or exposed to rain.
Connect to drinking water mains.
This appliance is not intended for use by young children or infirm persons without supervision.
Young children should be supervised to ensure that they do not play with the appliance.
IMPORTANT!
• DO NOT ATTEMPT TO SERVICE THIS MACHINE AS IT IS DANGEROUS AND COULD
CAUSE SEVERE DAMAGE TO THE UNIT.
•SERVICE SHOULD ONLY BE CARRIED OUT BY TRAINED, QUALIFIED PERSONNEL.
•WE STRONGLY RECOMMEND USING ONLY ORIGINAL REPLACEMENT PARTS
AVAILABLE FROM AN AUTHORIZED DISTRIBUTOR.
•WASTE AND OTHER MATERIAL SHOULD BE DISPOSED OF ACCORDING TO LOCAL
REGULATIONS AND PROCEDURES FOR WASTE DISPOSAL.
•CLEANING AND MAINTENANCE ARE NOT COVERED BY THE WARRANTY.

1.2. Description
Main Features of the Machine
▪18/8 stainless steel housing
▪Powerful speed reducer (24Kg./m. @ 7 rpm.)
▪Copper evaporator on precision bored tubing
▪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
1.3. Operating principle
Water enters water trough via a float valve which provides a constant head of water. Through a
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!
If unit is placed on top of a cold room, and/or ice has to fall a long distance from unit, a
MECHANICAL ICE LEVEL SENSOR should be installed. (except 50 and 90)
To prevent ice from compressing in cold storage, we recommend transferring ice through a
plastic tube (80-100 mm diameter) attached to its lower end the DISPERSION CONE which is
PROVIDED WITH THE MACHINE in all models. (except 50 and 90).

WATER TEMPERATURE ºC
Water quality = 500 ppm (240 Microhms/cm)
2.4. About Crushed-Ice production
IMPORTANT: Production figures have been obtained under the following conditions:
Water Quality: 550 ppm. total solids
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 factors. As shown,
production decreases as water temperature increases.
IT IS IMPORTANT THAT WATER INTAKE TUBE IS NOT CLOSE TO ANY HEAT
SOURCE. 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 (GR 560). 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%
• Ice production also decreases with improved water quality. (See graph for approximate
production variations).

3. DELIVERY & UNPACKING
Upon receipt, thoroughly inspect the packing container. If there appears to be damage to the
container contact the shipper immediately. Unpack unit in the presence of delivery personnel
noting any damage on the waybill.
ITV packing bears the “Green Point” on all models according to the European Directives on
management of Packaging and Waste Disposal.
Be sure to include model name and serial number on all claims. Serial number is located in the
following three places:
(1) Packing
There is a label stuck onto the cardboard packing bearing this serial number (1).
(2) Machine body
On the back of the machine (1).
(3) Rating plate and serial number
Located at the back of the machine.
Water cooled machines: check that the drainage hose at the back of the
machine is in good condition.
Verify that the installation kit is inside the bin, and has the following
pieces: scoop, 3/4’ water hose, two small filters and user manual.
In all models there is a large particle filter (5 micres) with accessories,
and an ice dispersion cone.

Granular Ice Technical Service Manual

COD: IQ02_404MTIN.DOC
WARNING: DO NOT LEAVE PACKING MATERIALS (PLASTIC BAGS, CARDBOARD
BOXES, ETC.) WITHIN REACH OF CHILDREN.
4. INSTALLATION
4.1. Recommended placement of unit
IMPORTANT!
ICETECH machines are intended to operate at room temperature between 5°C and 43°C and
with water temperature ranging between 5°C and 35°C. You may encounter evaporator/gearbox
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 condenser and/or water pressure valve, allow
sufficient space at front of the machine. Ensure that flooring is firm and even.

Granular Ice Technical Service Manual

COD: IQ02_404MTIN.DOC
4.2. 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 5-micron
filter 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.)
d) PURIFIED WATER: A 10% reduction in overall production may occur.
4.3. Connecting unit to water source (water-cooler units)
• 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.
4.4. 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%)
