2. RECEPTION OF THE MACHINE

Inspect the exterior of the packaging. If it is broken or damaged, complain to the haulier.

To checky whether the machine is damaged, UNPACK IT IN THE PRESENCE OF THE HAULIER and make a record on
the reception document, or on a separate document, of any damage that the machine may have suffered. Since 1
May 1998, it has complied with European regulations on the management
of Packaging and Packaging Waste.

Always record the machine and model number. This number is marked in
three places:

Packaging
There is an external label with the factory number.

Exterior of the machine
On the back, on a label that is identical to the front.

Name plate

Check that the installation kit is complete inside the machine. It is consists of: ¾ gas connection, two filter joints,
anchor bolts and the manual.

CAUTION: THE PACKAGING ITEMS (PLASTIC BAGS, CARDBOARD BOXES AND WOODEN PALLETS) MUST NOT BE
LEFT WITHIN REACH OF CHILDREN AS THEY ARE A POTENTIAL SOURCE OF DANGER

3. INSTALLATION

3.1 CONDITIONS OF THE LOCATION

The machines are designed to function in an ambient temperature of between 5ºC and 43ºC, and with water
input temperatures of between 5ºC and 35ºC.

Below these minimum temperatures, there may be difficulty in removing the cubes. Above the maximum, the life
of the compressor is shortened and production is considerably reduced.

3.2 WATER AND DRAINAGE CONNECTION

Bear in mind the following preliminary considerations on water quality:

Water quality has a significant influence on the quality, hardness and taste of the ice, and on the life of the
condenser in water-condensed machines.

a) Water impurities: larger impurities are retained by the filters which come with each machine. The filters must

2

be cleaned according to the purity of the water. For small impurities, we recommend the installation of a 5
micron filter.

b) Hard water: the ice will be less compact and the cubes may stick to each other. Some cubes may appear with
white marks. Inside the machine, lime deposits will form, which may interfere with its proper functioning. Water
condensate may obstruct the condenser or reduce its performance. To avoid incrustations it is advisable to install

a water filtering system. We recommend the use of a polyphosphate filter.

c) Highly-chlorinated water: the ice may taste of bleach (chlorine). In order to eliminate this taste, you can install
an activated carbon filter.

Bear in mind that you may receive water which is simultaneously affected by these three problems.

d) High purity water: production may be reduced by up to 10%.

3.3 CONNECTION TO THE WATER MAINS

Use the flexible connection (length 1.3 m.) with the two filter joints supplied with the machine. We do not advise the use of
double outlet taps with two stopcocks as they may close the rear one by mistake, leaving the machine without water. Water
pressure must be between 1 Bar and 6 Bar. If the pressure exceeds these values, install the necessary corrective components.

It is important that the water line does not pass close to sources of heat, and that the flexible hose or the filter does not
receive hot air from the machine. Otherwise this would cause production to decrease as the water would be heated.

3.4 CONNECTION TO THE DRAIN

The drain must be below the machine, by at least 150 mm.

In order to prevent bad smells, install a siphon. The drainage pipe should ideally have an internal diameter of 60 mm. and a
minimum slope of 3 cm per metre.

3.5 ELECTRICAL CONNECTION

The machine is supplied with a 1.5 metre cable. If the power cable is damaged, it must be replaced with a special
cable or set supplied by the manufacturer or the after-sales service.

The machine should be positioned in such a way that a minimum space is left between the back of the machine and the wall
so the plug on the end of the cable can be plugged in comfortably and without any risk.

Supply a suitable socket.

It is a good idea to install a switch and suitable fuses. The voltage and intensity are marked on the name plate and in the
technical pages of this manual. Voltage variations of more than 10% above that indicated on the plate may cause
breakdowns or prevent the machine starting.

The line to the socket must have a minimum cross-section of 2.5 mm2.

Check that the mains voltage and that indicated on the name plate are the same.

IMPORTANT: Ensure that there is a proper earth connection when connecting the machine. Consult the current legislation or
the regulations of the country where it is installed.

The electronic board has a button battery to maintain the time. In the installation, please remove the plastic protecting the
battery (board in the upper side, behind the display, remove two screws under the upper air grille, to access the electric box).

3.8 REMOTE CONDENSER UNIT

If you have purchased a machine with a remote condenser, follow the instructions for its installation.

STEP 1: PLACING BOTH UNITS (REMOTE CONDENSER AND SPLIT MACHINE) IN ITS LOCATION

CHECKING THE PROPER CONNECTIONS FOR EACH UNIT:

REMOTE CONDENSER:

 The condenser includes the condenser pressure switch
 It needs an electrical supply (check label with power supply specifications). It comes without an electrical

cable. Connect to the power supply directly (it does not need communication with the split unit).

 To connect, remove the rear cover, using a Torx screwdriver. The electrical cable must go through the

hole next to the piping hole. Use a 3x1.5 mm2 electrical cable.

Terminal connector to supply electrical power to the remote condenser, located behind the metallic cover.

 Level the unit correctly.
 Locate the remote condenser unit under a shadow. We advise to place it under a roof, whenever possible.
 The remote condenser unit works between 0ºC (32ºF) and 43ºC (109.4ºF) air temperature.

9

 Check the air direction through the remote condenser, always install the unit with the air direction out to

the ambient when installed in a wall, to avoid condensed air returning to the condenser.

 If more than one unit is going to be installed, please located them to avoid the condensed air going from

one unit to the other.

10

Refrigeration taps

INTERNAL UNIT:

 It needs an electrical supply (check label with power supply specifications). The unit comes with an

electric cable, and no plug.

 Water supply: it needs a water tap nearby. The unit comes with a water hose, ¾” GAS connection, and

two net filters.

 Drain pipe: The unit has two drain pipes. A drainage is need it. The drain pipes must be straight, no

siphons allowed, to let the water drain directly.

 Level the unit correctly.
 Always check the ice exit, to allow the ice cubes fall free.
 In case of stacking two units, please follow the stacking manual.

STEP 2: REFRIGERATION CONNECTION BETWEEN BOTH UNITS

REMOTE CONDENSER: Remove the rear cover if need it.

REMOTE CONDENSER PIPING CONNECTION

Gas pipe: up inlet 1/2”

Liquid pipe: down outlet 3/8”

 The remote condenser is sent from factory pressurized. To ensure there is no damage from the transport,

please check that is still pressurized, before cutting the pipes to start the connection.

 Always connect the remote condenser to the refrigeration pipes by welding. The remote condenser

comes with the inlet gas pipe closed, and the outlet liquid pipe with a gas intake. Cut both pipes to weld.

11

 Do the refrigeration installation between the remote condenser and the split unit. Check always that each

tube is in the correct position, and the pipes are not together (to avoid heat exchange between pipes. We
advise to insulate the liquid line.

 Try to do a clean installation, as straight forward as possible.
 The liquid line must always go from the outlet remote condenser (liquid, lower pipe) to the split unit

liquid inlet (3/8” tap), and the gas inlet from the remote condenser (upper pipe) to the gas outlet in the
split unit (1/2” tap).

 If the remote condenser is lower than the split unit, it is necessary to install a siphon in the liquid line,

near the remote condenser, to avoid the oil staying at the condenser.

 Do not install the remote condenser lower than 3 meters from the split unit.
 If the remote condenser higher or equal to the split unit, a siphon must be installed in the gas line, one

every 4 vertical meters and one every 8 horizontal meters.

SPLIT UNIT: It is connected by a gas tap 3/8” and a liquid gas tap ½”, using the nut that comes with the tap.

STEP 3: INSTALLATION LEAKING TEST AND VACUUM

 Once the refrigeration pipes are weld and connected, a leaking test must be done to

check that the line has no leakage in the nuts or the welding.

 After checking for leakages, a correct vacuum must be done. We advise to keep vacuum

for around 4 hours.
ATENTION: Do not open the gas taps from the split before doing the vacuum, as the unit comes with
refrigerant.

STEP 4: OPEN GAS AND LIQUID TAPS

 Once that everything is correctly installed and there are no leakages, and the vacuum

has been done properly, open the split unit, that comes with a refrigerant charge for 5 meters of distance

between the remote condenser and the split unit. Open slowly the liquid gas tap (3/8”) and then the gas
tap (1/2”).

12

STEP 5: ONLY FOR GREATER DISTANCES THAN 5 METERS BETWEEN UNITS

 If the distance between the remote condenser and the split is greater than 5 meters, it is

necessary to add some refrigerant. Add 40 grams per extra meter, up to 15 meters maximum.

STEP 6: START UP

 Now the split unit can be turn on to try it, and modified the control parameters if need it (electronic

board). Instruccions in the user manual.

NOTE: It is better to use the ambient probe from the split unit to obtain the temperature of the air getting
inside the remote condenser (in the air intake of the condenser). To do so, enlarge the probe cable and put
the probe in the condenser.

 Are the drains connected and do they work?
 Is it connected to cold water?
 ** If the machine is air condensed, are the air circulation and the temperature of the premises right?

 Is the water pressure correct?

NOTE: If the incoming water pressure is greater than 6 Bar, install a pressure reducer.

CAUTION: CHECK THAT THE VOLTAGE AND FREQUENCY OF THE MAINS ARE THE SAME AS THOSE INDICATED ON
THE NAME PLATE.

4.2 START UP

After following the installation instructions (ventilation, conditions of the premises, temperatures, water quality,
etc.), proceed as follows:

1. Open the tap to let water flow. Check that there are no leaks.

2. Connect the machine to the mains with its corresponding protection.

3. Activate the button on the display installed on the front of the machine.

4. Check that there is no part which is rubbing or vibrating.

5. Check that the curtain can move freely.

6. Check that the injectors send the water to the evaporator in the correct direction.

7. Check that the collectors turn freely on their axles.

8. Once 10 minutes have passed, check that the water container has no leaks through the maximum level overflow

channel.
Note: The electronic plate has a battery to keep the date and time. The battery is protected with a plastic to
prevent their consumption. The first time using the unit, remove the plastic (opening the upper compartment,
display area, access to the electronic board box and inside is the battery with plastic).

5. OPERATION

5.1 OPERATING PRINCIPLE

1. When the start button is pressed, the machine begins with a starting timed period, during which the water inlet
electro-valve (EA) is opened.

2. After this timed start, the working cycle begins:

3. It starts with the detachment operation.

4. When the detachment time begins, the hot gas electro-valves (GC) and the water inlet electro-valves (EA)
remain open, and the compressor and fan start up. The water pump runs for 30 seconds to help detachment.

5. When detachment is complete, ice-making begins.

6. The compressor (C) and the fan (V) continue to work, the pump (B) starts and the hot gas valves (GC) and water
inlet valves (EA) close.

7. From this moment on, the evaporator begins to cool during the production time.

8. Once the production time has finished, the detachment process will begin again.

15

Harvest

9. Each entire cycle is considered to begin when the production time starts and ends when the
detachment time has finished, at which point a new production cycle begins.

*The hot gas electro-valve GC has to open during 5 seconds before the compressor starts. The remaining
components are stopped, including the compressor.

*Expansion controlled by expansion valve.

5.2 DISPLAY

5.2.1 MACHINE OPERATING STATES

Machine off

The time is shown on the display when the machine is off (no light). When the machine is disconnected from the
power supply the time is lost. When reconnected it starts at 00:00, flashing to indicate that the time is not set.

Start

When the machine is working during the start time, the display will appear as follows:

Detachment

When the machine is working during the detachment time, the display will appear as follows:

At the bottom of the screen it will show the temperature indicated by the SC cycle probe.

16

Washing

Production

When the machine is working during the production time, the display will appear as follows:

When the detachment has finished the screen will show a progress bar with the time remaining until the end of
the cycle.

It will also show the following text at the bottom of the screen: “Fabr.: -12ºC”, with the temperature indicated by
the SC cycle probe.

As the production time is “tf=tfv+tff” and at the start it is not known how long the “tfv” will last, since it depends
on the “Tfc”, take as a reference: cooling time “tfv” of the last cycle + set production time “tff”.

If the tfv of the last cycle is not known, use a time of 25 minutes (total production time tf=tfv+tff) for the
calculation (for example, in the first cycle of the machine).

Once the cycle has started and, as soon as point 4 on the graph is reached, you will know exactly the time
remaining until the end of the cycle, because "tf" will be defined at that time. Therefore, at this point, the bar will
be recalculated so that it reaches the end just as the cycle has finished.

Cleaning

Only the water pump works. It can be accessed with the machine off, pressing simultaneously the “OK” and
power “I” buttons for 3 seconds.

The display will show:

To end the cleaning cycle, press the power button “I” and the machine will turn off.
