INSTALLATION
EMPLACEMENT GUIDELINES
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 DPmachines are designed to operate at room temperature between 10ºC (50ºF) and
43ºC (109.40ºF).
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 less.
The air flow in air-condensed machines enters through the front grille, entering on the right
front and exiting on the left front side. In addition, the unit is equipped with a rear air vent. Do
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.
THIS ICE MAKER IS NOT DESIGNED FOR OUTDOOR OPERATION.

not obstruct the front grille with any objects.
The unit can operate embedded, but with a reduction in output.
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 COOLED UNIT.
IT IS IMPORTANT THAT THE WATER PIPING DO NOT PASS BY OR NEAR SOURCES
OF HEAT SO AS NOT TO LOSE ICE PRODUCTION.
The machines expel hot air through the grids and this air has to go to the environment and
not accumulate. This is particularly important with the air ejected from the back of the
machines: you must leave a space to the wall of a minimum 10 cm, allowing air to flow from
behind and with an exit so that there is a renewal of the same, avoiding the formation of hot
air pockets in this area that could reduce the ice production of the machine and even activate
its overheating protector and cause it to stop.
THREAD THE SUPPORT LEGS TO THE BASE OF THE MACHINE ON THE
HOUSING SET TO SUCH END AND REGULATE THE HEIGHT AS TO HAVE THE
EQUIPMENT PERFECTLY LEVELED.
Exits/renewals of the air between the rear of the machine and the wall
must be provided for.

Water and Drainage
Water quality has a remarkable influence on the appearance, hardness
and flavor of the ice as well as, on the machines condensated by water,
on the life of the condenser.
Connections to the Water Network
Use a flexible pipe (1.3 m –4.27 feet length) with the two filter joints
supplied with the machine. Arrange the necessary appliances
according to regulations or current norms to prevent water return to
the network.
Pressure should be established between 0.1 MPa and 0.6 MPa (1-6
BAR)
If pressures overpass such values, install the necessary corrective devices.
Connection to Drainage
Drainage should be located lower to the machine level, at 150 mm (5.91 inches)minimum. It
is convenient that the drainage pipe is of 30 mm (1.18 in) of interior diameter and with a
minimum gradient of 3 cm (1.18 in) per meter (see figure).
Electrical Connection:
Caution:
•The positioning of the device must ensure that the power connection is not damaged or
pinched.
•Do not install multiple portable power outlet strips orother portable power supplies in back
of the device.
The machine is supplied with a 1.5 m (4.92 feet) cable of length. In case the supply cable is

damaged, it should be replaced by a cable of special assembly to be furnished by the
manufacturer or post-sale service. Such replacement should be performed by qualified
technical service only.
The machine should be places in such a way as to allow a minimum space between the back
and the wall to allow an easy access and without risks to the cable jack.
Safeguard the base of the jack.
It is advisable to install a power switch and the appropriate electrical safety devices in
accordance with local and/or national regulations in each case.
START-UP
Previous Checkup
a) Is the machine leveled?
b) Voltage and frequency are the same as those on the nameplate?
c) Are the discharges connected and operating?
** If air condensed: Is the air circulation and its temperature appropriate?
** Is water pressure appropriate?
NOTE: In case input water pressure is higher that 0,6 MPa (6 Bar) install a pressure reducer.
THE FAUCETCONNECTION PRESSURE SHOULD NEVER BE REDUCED.
START-UP
Once the installation instructions are followed (ventilation, site conditions, temperatures,
water quality, etc.), proceed as follows:
1) Connect to drinking water network. Open thewater inlet. Verify the existence of leakages.
2) Open the door and remove the protection elements that are inserted on the curtain.
3) Connect the machine to the electrical network.
4) Verify that there are no vibrations or frictions on the elements.
5) Verify that the curtain moves freely.
6) The machine has a timer governing startup, allowing for water to be recharged for the
production cycle
7) Verify that the nozzles send the water to the evaporator on the right direction (even
spread).
8) Check the cubes after two cycles; they should be uniform in shape. If they do not come
out correctly, or the unit does not make ice, contact an authorized service technician.
9) The unit produces ice until the bin is full, using a stop sensor. When the ice is removed
from the bin, the unit will once again produce ice.
ROOM WATER
MAXIMUM 43ºC (109.40ºF) 35ºC (95ºF)
MINIMUM 5ºC (41ºF) 5ºC (41ºF)
