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 DP machines are designed to operate at room temperature between 10ºC (50ºF) and 43ºC (109.40ºF).
Below the minimum temperatures, the gear motor is forced excessively. Above the maximum, compressor life is shortened and production decreases considerably.
Do not place anything on the fabricator or against the front grille.
For condensed air machines (Figure III), if the front air intake is insufficient, the exit is totally or partially obstructed, or if by its placement it is going to receive hot air from another device, we strongly advise, in case of not being
able to change the site of the machine, INSTALL A WATER CONDENSER.
3.1 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.
3.2 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).

3.3 ELECTRICAL CONNECTION
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
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.
The machine is supplied with a 1.5 m. long cable. If the power cable is damaged, it must be replaced by a special cable or assembly to be provided by the manufacturer or the after-sales service. Such replacement must be performed by the qualified technical service.
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.
Voltage and tension are indicated in the nameplate and on the technical specifications of this manual. Variation on voltage above the 10% stated on the nameplate could
result on damages or prevent the machine start-up.
3.4.- INSTALLATION OF EQUIPMENT ABOVE TANKS/BINS
The modular manufacturers must be installed on tanks or bins, following the instructions contained in this manual.
The strength and stability of the container-machine/s assembly must be verified, as well as the fixing of the elements.
The drain must be lower than the drainage area of the tank/bin an, the hose must always be in a descending position, NEVER ascending, (Figure IV).
IT IS IMPORTANT THAT THE WATER PIPE DOES NOT PASS BY OR NEAR HEAT SPOTS TO NOT LOSE ICE PRODUCTION
