WARNING
The instructions of this manual are exclusively directed to the Technical Assistance
Service personnel.
The installation of this equipment should be done by the Technical Assistance
Service department.
ALWAYS disconnect the power supply from the machine BEFORE any cleaning or
maintenance service operation.
Any change needed on the electrical installation for the appropriate connection of
the machine, should be exclusively performed by qualified and certified
professional personnel only.
Any use of the ice maker not intended to produce ice, using drinking water, is
considered inappropriate.
It is extremely dangerous to modify or intend to modify this machine, and shall
make any type warranty void.
This machine should not be used by children or handicapped without the proper
supervision and monitoring.
Children should be monitored to assure that they do 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.
In order to assure the proper operation and efficiency of this equipment, it is of
paramount importance to follow the recommendations of the manufacturer,
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.

SPECIALLY THOSE RELATED TO CLEANING AND MAINTENANCE
OPERATIONS, which should be performed mostly by qualified personnel only.
DESCRIPTION
The most significant characteristics are:
•18/8 Stainless steel bodywork
•Telescopic guides for maintenance
•Anti-lock injectors.
•Pump without seals.
•R134A refrigerants
•Safety pressure switch in High
•TRANSPARENT ICE CUBES mainly with water network.
OPERATION PRINCIPLE
WHEN STARTING UP THE MACHINE FOR THE FIRST TIME, IT WILL BE IN
THE WATER REMOVAL-INLET CYCLE.
In this moment, the compressor is functioning and the water and gas inlet valves
are opened. The necessary water amount is loaded for the manufacturing of the
next ice cycle and the excess goes to the drainage through the maximum level
overflow tank.
Once the specified time goes by, the hot gas and water entry valves close. The
pump starts and sends water through the injectors against the molds of the cubes,
where the ice is formed little by little. At the same time, the evaporation
temperature decreases until the cubes are completely made. When this period of
time goes by, the removal cycle starts (1.5-2 minutes). Now, the pump is stopped
and the hot gas and water entry valves are activated.
Once the removal cycle has ended, the machine starts producing ice until the
storage is full. This is when the stop order will be given.
With the purpose of not having non-terminated ice cubes, if when the stock
thermostat detects that the storage bin is full, and the cycle is already started, it will
end it.

classification (TROPICALIZED).
NOTE: Controlled expansion per capillary.
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
reception document, or on a separate instrument.

Always state the machine number and model. This number is printed on two
locations:
Packing
On the outside, it contains a label with the manufacturing number (1).
Exterior of the Equipment
On the outer part of the packing, there appears a label with the same
characteristics as the previous one (1).
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.
INSTALLATION
Location zone conditions.
The HNG machines are designed to operate at room temperature between 5ºC
(41ºF) 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 machines take air for the ventilation on the front part and they expel the air
through the back part.
If the front air input is not free or the exit is totally or partially blocked, the machine
will not work correctly and the production will be affected.
The water pipe shall not go near the heat focus so as not to lose production.

Housing dimensions.
To install the ice manufacturer in the correct way, it will be necessary that the hole
located for such effect in the piece of furniture has the dimensions established in
the drawing (560x440x560 mm.).
The drainage must be in the position established in the drawing. In the left part of
the housing and below the inferior level of the machine. In this way the flexible
pipes have the enough path to allow the extraction of the machine.

IMPORTANT
It must be taken into account that an exit must be left for the air that the machines
takes through the front louver. It can be a back hole (with an outdoor exit) or a
louver on the machine.
The water connection, drainage and electrical steps of the equipment are also
necessary. (see the figure)
Anchoring of the machine
Follow the following steps:
1- Screw the guides in the hole of the piece of furniture to have them
horizontally and set back 5 mm as it is indicated on the figure.
