These water coolers were designed to provide large quantities of still and
carbonated cold water.
They are easy to use and manufactured using top quality materials, offering
the utmost hygiene and ease of maintenance; a UV safety system, available
as an optional in the ground and counter-top models (TOP). It protects the
water distribution area from bacteria (patented system).
They should always be connected to a mains drinking water supply and can
be tted with special ltering kits.
They can be used in various settings, ranging from cafés, restaurants,
canteens, hospitals, public places, ofces and domestic environments; they
should always be installed indoors and in the environmental conditions
described under the “technical features” heading.
They are equipped with an internal cooling system, capable of supplying
water cooled to 3 ÷ 10°C.
They use a direct cooling system (ice bank)

pipe to prevent narrowing or rising.
In the SL models, the clean water drainage pipe is already provided with a
siphon inside the cabinet (g. 16.1); connect said pipe to the drainage ensur-
ing it is not bent, otherwise it prevents the siphon from draining the water.
• Connection to the mains water supply is carried out with the aid of pipe
T provided (8mm diameter).
• The pipe terminal A (g. 12) (3/8”) must be connected to the mains supply
by means of a stop cock R (not provided).
• Connect the pipe T to the stop cock, making sure that the o-ring gasket
is correctly positioned onto the attachment A.
• Connect the tube T to the connection 7 (f i l l i c e b a n k ) and ll the ice tank;
once reached the right level, the exceeding water is eliminated from the
draining 13 (g. 15).
• Take off tube T from the connection 7 and connect it in the connection 1

ELECTRICITY CONNECTION
Connection to the mains electricity supply is carried out by connecting the plug to
a mains socket
(g.16).
The supply socket must be equipped with an efcient earth plate and it must be sized
for the load of the appliance (see technical characteristics).
Make sure that the mains voltage corresponds with what is specied on the data plate.
Make sure that there is an omnipolar switch above the socket with a minimum contact
break of 3 mm protected by fuses of suitable amperage for the absorption of the
appliance itself (see technical characteristics and data plate).

3) CO2pressure regulator
4) CO2pressure adjusting screw
5) CO2outlet pipe
6) Cylinder internal pressure gauge
(shows whether there is any gas inside the cylinder)
7) Outlet CO2pressure gauge; the value should be of 3÷4 bars.
This value is set at the factory.
If necessary, turn screw 4.
• Turn tap 2 of the CO2cylinder.
• Press the pushbutton for carbonated water .
• Let a few litres of water ow until carbonated water begins to come out.
Attention!
Upon occurred installation, a correct flow of carbonated water
takes about 20 seconds to distribute 1 litre.
Attention!
The results of pressure variations on carbonation will only have effect
when at least 2 litres of water have been drained off.

V
Advice on using the appliance for carbonated water
To guarantee the correct operation of the pump in time, the appliance must always
be operated with water in the cooling circuit.
The quality of the carbonation process also depends on the temperature
of the water, which means you should wait for the water cooler to have
cooled the water down sufciently upon installation and the ice bank has
been formed.
Both still and carbonated water can be dispensed by pressing the relative
buttons after approximately 40 minutes.
When installing the appliance, or when replacing the CO2cylinder, or if
the water cooler has no water left inside it, a few air bubbles may enter the
carbonation device.
These air bubbles could diminish the quality of the carbonation process, and
we therefore recommend you remove them:
• Close the
CO2
cylinder
• Drain the circuit by pulling the outlet valve ring V.
• Reopen the
CO2
cylinder
• Drain off at least two litres of sparkling water
6.4
HYGIENIC CLEANING
• Once you have checked that the appliance works properly, go on to the
“internal cleaning and hygienic cleaning” stage as described in chapter 8.
GB
If mains water is insufcient, a protection system intervenes and blocks pump
functioning (the NO WATER warning light is illuminated).
• The pump is blocked after 4 minutes of continual working.
To restore functioning the apparatus must be disconnected from the electrical
network and reconnected when there is sufcient water in the mains system.

• The operation of higienization/sterilization has to be carried out every time
the refrigerator is installed and:
- every 6 months when it is used (*)
- every time the water lter is changed
- after an inoperative period of one or more weeks
(*)If the refrigerator is installed in Hospitals, Schools, Old people’s homes,
or Clinics, it is recommended to sterilize it every 3 months
Hygienic cleaning solution preparation
• Prepare 5 litres of water
• Add to it 5% of “hydrogen peroxide” at 130 volumes; for the doses, use a graded
measure or an ordinary syringe
NB: if you use commercial hygienic cleaning solutions, keep to the instructions
provided by the manufacturer and included in the package.

DIAGNOSIS AND OPERATING ANOMALIES
This section includes the typical anomalies that could occur.
Many of these problems are not caused by the cooler, but they could be brought about by the electricity supply or by an incorrect use of the water cooler.
In the ANOMALY column, the problems reported by the customer are listed.
In the POSSIBLE CAUSES column, the “probable reasons” behind the problem are listed.
In the INTERVENTION column, the corresponding corrective action is listed.

INTERNAL CLEANING/ HYGIENIC CLEANING
WARNING! Considering that the products used for the hygienic cleaning are acid and alkali corrosive substances, disposable gloves must be used
as well as glasses to protect your eyes. When this hygienic cleaning is carried out, you must keep to the product reaction times, percentages of
hygienic detergent and quantity of water necessary for rinsing.
Warning! If the appliance is equipped with a chlorine filter, proceed as
follows:
Remove the filter cartridge and fit on the false cartridge mod. TEST CAN.
• With the help of a pump P, connect the appliance’s water inlet to the container with
the disinfecting solution.
• Start the pump up so a disinfectant solution enters the machine and then, at the same
time, open the taps so that the disinfectant runs from the distribution nozzles.
• Before the solution runs out, stop the pump and interrupt the dispensing.
• Leave the disinfectant to act for at least 20 minutes.
• Reconnect the appliance to the mains water supply.
• Let at least 15 litres of water flow out of the taps so as to rinse the hydraulic system
suitably, before using the appliance again.
Warning! The operations should be carried out by a qualified professional.
