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.

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.

2- Screw the fastening bridge of the machine in the position of the drawing.
3- Screw the fastening flanges of the drainage hoses
4- Place the machine on the support angles of the guides. Adjust the wide
before fastening the screws checking that it slides softly along the path.

Water and Drainage
The water quality notably affects the quality, hardness and taste of the ice.
Have in mind the following considerations:
a) WATER IMPURITIES:
The big ones are retained by the filters that accompanied each machine. Its
cleaning will be more or less periodic in function of the water purity. For the small
impurities we recommend the installation of a filter of 5 micron.
b) WATER WITH MORE THAN 1000 PPM:
The ice will be less hard and will stick a bit in the stock. There can be ice cubes
with white marks. In the machine, there will be lime deposits that can interfere with
its good operation. Water hardness is corrected with the installation of a good
decalcifier.
c) VERY CHLORATED WATER:
The ice gives a bleach (chlorine) taste. To eliminate such taste a coal filter can be
installed.
Have in mind that water can be received with the three cases simultaneously.

d) WATER OF HIGH PURITY:
Production can decrease up to a 10%.
Connections to the Water Network
Use a flexible pipe with the two filter joints supplied with the machine. Pressure
should be established between 1 and 5 Kg/cm
2
If pressures overpass such values, install the necessary corrective devices.
Leave free the needed length to extract the machine up to the end of the guides.
The rest can be flanged and gathered at a side to avoid that when storing the
machine it can touch the water pump and stop it or make noise.
Connection to drainage
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.
it is convenient that the drainage pipe has an entry with an interior diameter of 50
mm to introduce the two drainage hoses of the machine.
Fix the pipes with the flanges that were provided. Thus, we ensure that when
taking out and storing the machine, the pipes do not come out.
Electrical connection:
The machine is provided with a 1.5 m (4.92 feet) cable with a schucko jack. In case
the supply cable is damaged, it should be replaced by a cable or a special
assembly to be furnished by the manufacturer or post-sale service.
Safeguard the base of the jack.
It is convenient to install a switch that allows the total disconnection of the machine
without taking it out.
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.

Voltage and tension are indicated on 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.
The line up to the base of the socket shall have a minimum section of 1.5 mm
2
.
Check that the voltage of the net and the indicated one is the same.
START-UP

MAINTENANCE AND CLEANING PROCEDURES
**
CAUTION:
For all cleaning and maintenance operations: Disconnect the
machine from the power supply.**

Air Condenser-filter
1) Disconnect the machine.
2) Take out the front louver. (pull out the lower clips)
3) Vacuum clean, wash or substitute the filter.
4) Dismantle the lateral lid that covers the condenser
5) If it is necessary clean the louvered area with the help of an aspirator with a
brush, non-metallic brush or low-pressure air.
Evaporator / water container
1) Prepare a solution at the 50% of phosphoric acid and distilled water. Do not use
hydrochloric acid. Pour this solution slowly in the top of the evaporator, until it
overflows in the water container. The mixture is more effective with the water
between 35ºC and 40ºC.
2) Leave the solution acting during 10 minutes.
3) Take out the overflow, wait until the water container is empty. Place the
overflow.
4) Close the water inlet.
5) Refill the system until the maximum level of the water container with the same
solution. Connect the machine (the water must be closed) and wait 20 minutes.
6) Open the water, connect the machine.
CAUTION: ** Eliminate the ice manufactured in this first cycle.
NOW THE SANITARY CLEANING STARTS.
6) Connect the machine and once there is no more water entering, remove the
evaporator lid and pour the bleach (one glass) in the same. Wait 20 minutes.
7) Disconnect the machine and connect it again, once the ice has fallen, THROW
it and leave the machine performing the complete cycle.
CAUTION: ** Eliminate the ice manufactured with this procedure.
8) Clean and mount all the components, and check that the louver is clean and
that the ice cubes slide well. Check that in the shield no slat gets blocked.
Review and/or change the water input filters.

9) CHECK THAT THE INJECTORS ARE PROPERLY LOCATED, THAT THE
WATER SPREAD FORMED BY THE INJECTORS ARE UNIFORM AND THAT
ALL OF THEM ARE EQUAL. If possible, disassemble, clean and place in the
correct position.
Ice storage bin cleaning.
1) Disconnect the machine, close the water and empty the ice-cube storage bin.
2) Use a dish cloth with detergent.
3) In case the white lime spots remain, rub them with a soft antilime, wait a few
minutes and use again a dish cloth. Clear with water, dry and start the machine
again.
Exterior Cleaning
Use the same procedure as the one indicated for the ice storage bin.
Collectors and Injectors
1) Remove the shield. (Take the time to clean it with phosphoric acid, clean with
bleach and clear under water).
2) Remove the louver of ice drop. (Clean as done with the shield).
3) PULL THE COLLECTOR UPWARDS. IT IS PRESSURE MOUNTED.
4) Disassemble the injectors and lids, and clean them.
5) Disassemble and clean the main head filter. (IT IS PRESSURE MOUNTED).
6) Assemble the filter, injectors and collector.
CAUTION
IT IS REALLY IMPORTANT THAT WHEN PLACING AGAIN THE COLLECTOR
THE INJECTORS ARE COMPLETELY PERPENDICULAR TO THE SAME, IF IT
IS LEFT BLENDED THE ICE CUBES OF THE EDGES CAN BE LEFT WITHOUT
WATER.

7) Mount the ice cube removal louver. (CAUTION: It must be locked in the back
scaffolds.
8) Mount the shield. Ensure that ALL the slats move freely.
9) Start the machine and THROW THE FIRST BATCH OF ICE.
Cleaning of the Inlet Filters
They are easily obstructed during the first days of operation, MAINLY WITH NEW
PIPING INSTALLATIONS.
Loose the hose and clean it under water.
