USER MANUAL NG

MANUAL IS PART OF THE PRODUCT. READ IT CAREFULLY IN ORDER TO USE AND MAINTAIN THE

THIS
EQUIPMENT CORRECTLY.
IT IS IMPORTANT TO KEEP IT FOR FUTURE TROUBLESHOOTING AND REFERENCE.

Warning

The installation of this equipment should be done by the Technical Assistance Service department.
The socket should always be placed on an accessible location.
ALWAYS disconnect the power supply from the machine BEFORE any cleaning or maintenance service.
Any change needed on the electrical installation for the appropriate connection of the machine, should be exclusively
performed by qualified and certified professional personnel.
Any use by the ice maker not intended to produce ice, using drinking water, is considered inappropriate.
It is extremely dangerous to modify or to intend to modify this machine, and shall make any type warranty void.
This appliance is not intended for used by persons (including children) with reduced physical, sensory or mental
capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning
use of the appliance by a person responsible for their safety.
Children should be monitored to assure that they should not play near the equipment.
This machine is not intended to be used outdoors nor exposed to the rain.
Connect the equipment to the drinking water network.
The machine should be connected using the power cable supplied with the equipment. The connection is not intended
for fixed cabling.

IT IS MANDATORY TO GROUND THE EQUIPMENT. To avoid possible discharges on individuals or damages to the
equipment, the machine should be grounded pursuant local and/or national regulations as the case may be.
THE MANUFACTURER SHALL BE HELD HARMLESS IN CASE OF DAMAGES ARISING DUE TO THE LACK OF THE
GROUND INSTALLATION.

In order to assure the proper operation and eciency of this equipment, it is of paramount importance to follow the
recommendations of the manufacturer, SPECIALLY THOSE RELATED TO CLEANING AND MAINTENANCE OPERATIONS,
which should be performed mostly by qualified personnel only.

CAUTION:

Do not try to perform repairs. The intervention of non-qualified personnel, besides of being dangerous, could result in
serious malfunctioning. In case of damages, contact your distributor. We recommend always using original replacement
and spare parts.
Perform all discharge and recovery of materials or waste according the national regulations in force.

Reception of the Machine

Inspect the outside packing. In case of damages, MAKE THE CORRESPONDING CLAIM TO THE CARRIER.
To confirm the existence of damages, UNPACK THE MACHINE IN THE PRESENCE OF THE CARRIER and state any
damage on the equipment on the delivery document or on a separate instrument.

2

Always state the machine number and model. This number is printed on three locations:

(1) Packing: On the outside, it contains a label with the manufacturing number.

(2) Exterior of the Equipment: At the rear side of the equipment, there appears a label with the same characteristics

as the previous one.

(3) Nameplate:

Check that in interior of the machine the installation kit is complete and comprises:

• Ice scoop, four legs and manual.

• Warranty and serial number.

CAUTION: All packing elements (plastic bags, carton boxes and wood pallets) should be kept outside the reach of
children, as they are a source of potential hazard.

At the back of the machine.

Installation

THIS ICE MAKER IS NOT DESIGNED FOR OUTDOOR OPERATION.

An incorrect installation of the equipment may cause damages to individuals, animals or other materials, being
the manufacturer not responsible for such damages.

CAUTION:

The NG machines are designed to operate at room temperature between 41ºF (5ºC) and 109.40ºF (43ºC).
There may be some difficulties in ice- cube removal under the minimum temperatures. Above the maximum
temperature, the life of the compressor is shortened and the production is substantially lower.

3

USER MANUAL NG

The NG machines with air-cooler condenser take the air through the front section, and drive it o through the lateral,
back and also front louvers due to their new oblique condenser structure and placement.
Do not place anything over the maker or in facing the front louver.
In case the front louver is not enough, the exit is either total or partially obstructed or due to its placement it will receive
hot air from another device, we recommend, in case it is not possible to change the location of the machine, to install

a water condenser unit.

IT IS IMPORTANT THAT THE WATER PIPING DO NOT PASS BY OR NEAR SOURCES OF HEAT IN ORDER NOT TO LOSE ICE
PRODUCTION.

(1) Water and Drainage

Water quality has a remarkable influence on the appearance, hardness and flavor of the ice as well as, in the
machines condensed by water, on the life of the condenser.

(2) Connections to the Water Network

Use a flexible food grade pipe.
Pressure should be established between 14 and 85 psi (1 and 6 Bar / 0.1 and 0.6 Mpa).
If pressures overpass such values, install the necessary corrective devices.
ATTENTION: The machine shall be plumbed according to applicable Federal State and local regulations.

(3) Connection to Drainage

Drainage should be located below the level of the machine, at 5.91 inches (150 mm) minimum.
It is convenient to use a 1.18 in inside diameter pipe (30 mm) with a minimum gradient of 1.18 in (3 cm) per meter

(see figure).

TORY TO GROUND THE EQUIPMENT: To avoid possible discharges on individuals or damages to the
equipment, the machine should be grounded pursuant local and/or national regulations as the case may be.
THE MANUFACTURER SHALL BE HELD HARMLESS IN CASE OF DAMAGES ARISING DUE TO THE LACK OF THE GROUND
INSTALLATION.

The machine is supplied with a 6 feet length cable. In case the supply cable is damaged, it should be replaced by a cable
or a special kit to be furnished by the manufacturer or post-sale service. Such replacement should be performed by
qualified technical service only.
The machine should be placed to allow a minimum space between the back and the wall in order to guarantee an easy
and a risk free access to the plug.
Safeguard the socket. It is convenient to install adequate switches and fuses.
Voltage and tension are indicated on the nameplate. Variation on voltage above the 10% stated on the

nameplate could result on damages or prevent the machine from start-up.

(5) Safety Brackets (not necessary for models NDP55 and NG95).

1) Level the machine with adjustable feet.

2) Assembly the two brackets symmetrically using the milled screws (A) . fig 1,2 . Tighten by hand.

3) Fit the brackets to the wall with two screws for each one.

USER MANUAL NG

For cleaning or maintenance purposes just remove by hand the two milled screws to release machine from brackets.
Remember to secure machine again after operation.

NOTE: In case input water pressure is higher that 85 psi (6 bar / 0.6 Mpa), install a pressure regulator.

(2) Start-Up

Once the installation instructions are followed (ventilation, site conditions, temperatures, water quality, etc.), proceed
as follows:

1) Open the water inlet. Verify the no existence of leakages.

2) Open the door and remove the protection elements that are inserted on the shield.

3) Connect the machine to the electrical network.

4) Push the (blue) switch placed ound on the front side.

5) Verify that there are no vibrations or frictions on the elements.

6) Verify that the shield moves freely.

7) Verify that the nozzles send the water to the evaporator on the right direction (even spread).

8) After 10 minutes, verify that the water container has no leakages through the maximum level overflow pipe.

9) Verify that after the final cycle, the frost around the aspiration pipe is at 0.78 in (20 mm) of the compressor.

The technical installer shall invoice traveling expenses, labour cost hours and materials used.

Maintenance and Cleaning Procedures

CAUTION: Instruct the user about maintenance, informing that maintenance and cleaning operation as well as damages
due to the lack of such operations are not included in the warranty.
If a good maintenance is performed, the machine will continue producing a good quality of ice and will be free of
damages.
Maintenance and cleaning intervals will depend on the conditions of the site and water quality.
CAUTION: At least, one revision and cleaning should be performed every six months.
On dusty environments, it might be necessary to clean the condenser on a monthly basis.

CAUTION: Unit should always be disconnected during maintenance/cleaning procedures.

FRONT GRID REMOVAL

To access condensing unit remove front grid by pressing the two clips placed at right side.

CLEANING THE CONDENSER
