Checking the relationship of the appliance and the manual
The refrigerant in the appliance must fi rst be checked on the rating plate of the appliance.
The rating plate of the appliance indicates the serial number of the appliance. If the manuals are missing, it is possible to order new ones from the manufacturer or the local representative. When ordering new manuals it is essential to quote the serial number shown on the rating plate.

Safety

Safe use of the appliance

The appliance must be connected to an earthed socket. When moving or servicing the appliance, always unplug it from the power supply.
WARNING
The refrigerant and charge is declared on the rating plate. Refrigerant R290 (propane) is highly fl amiable. Handle equipment that contains R290 with extra care.
Under no circumstances should the value set at the factory of the refrigeration unit be set colder. Chang-ing the setpoint can cause the refrigeration unit to freeze and the actuators connected to it, such as the taps, to break. At worst, water damage can result. ” Modifying the equipment without the approval of the manufacturer invalidates the manufacturer’s product liability. Dangerous situations may arise if the given instructions are not followed. The manufacturer declines all responsibility for any operations carried out on the appliance without following the instructions in this manual.

Disposal of the appliance
The appliance contains parts and components, the disposal of which requires special treatment. Contact local authorities to obtain instructions on how to dispose of the appliance.

Functional description

Intended use of the appliance
The appliance is intended for cooling and dispensing drinking water.

Structure and operating principle
WD, WD-E, WD-N, WD-EN, WD-2, WD-E2, WD-N2, WD-EN2 are free-standing models and designed to be situated in a serving line.
Models D-I WD , D-I WD-E, D-I WD-N, D-I WD-EN, D-I WD-2, D-I WD-E2, D-I WD-N2, D-I WD-EN2 are delivered without an outer casing and are designed for insertion into a line structure.he top has a faucet and a basin with a drain for drip water.

Electronic faucet (models PWD-04A-E, PWD-04A-EN, D-I WD-E, D-I WD-EN)
The faucet is turned on and off by means of a solenoid valve actuated by a photocell. When a glass is held within the photo ll’s sensing range, the solenoid valve opens and water starts to fl ow. The faucet turns off automatically after the adjusted fl ow period. The faucet works best with a fl at-bottomed glass.

Operating instructions

Mechanical faucet: Push the lever with a glass. Electronic faucet: Hold a glass under the faucet.

Cleaning the exterior surfaces
Clean the stainless steel surfaces with neutral, liquid detergents. Abrasive or corrosive agents must not be used.

Cleaning the condenser (to be performed by a service technician)

Disconnect the appliance from the power supply before cleaning the condenser. Depending on circumstances, the condenser should be cleaned once a year or more often, if necessary. Condenser clogging is apparent when compressor running times get longer, the cooling effect decreases and the condensing temperature rises. Finally, condenser clogging can damage the compressor. When cleaning the condenser with a brush, be careful not to damage the condenser. The condenser can also be cleaned using a vacuum cleaner.

Replacing the fi lter (option) (to be performed by a service technician

If the appliance is supplied with an optional fi lter, we recommend replacing it at the intervals of 4800 liters or once the fi lter is clogged. The fi filter is clogged when the water output starts to decrease and the water fl ow becomes weaker. Depending on the frequency of use, the fi lter should be replaced approximately every six months.

Cut off the incoming water and run water from the faucet to release the pressure. Screw the cover off the holder  Remove the old fi lter . Insert a new fi lter inside the cover and screw the cover to the holder.

Installation

The appliance is designed to function in locations with temperatures of 10°C to 35°C. The appliance must not be installed close to appliances that generate heat, e.g. ranges. If the water pressure at the installation site exceeds 5 bar, the device’s water connection must be equipped with a pressure reducing valve The appliance should be stored in a dry place, at a temperature over +1°C. If the appliance has been exposed to a temperature below 0°C, it must be drained (allowed to melt). After melting, before taking the appliance into use, make sure that there is no damage to or leakage in piping. Electronic faucet: It is essential to take care that water in the faucet and solenoid valve does not freeze.

Unpacking the appliance
The appliance should be transported to the installation site in its transport package. Do not remove pack-ing until just before installation to prevent dust in the installation place from damaging the appliance. The appliance should be stored and transported in an upright position. The appliance should be placed in a well-ventilated room. Avoid placing the appliance in direct sunlight. The appliance must be installed in a vertical position with an accuracy of ±3°. Greater skewness may cause malfunctions. When installing D-I models care must be taken that the machinery is not positioned directly on the fl oor, but an air gap of at least 10 cm is left between the machinery and the fl oor. This is to make sure that water, possibly dripping onto the fl oor, would not damage the electrical components of the machinery and cause hazardous situations. The compressor is equipped with damping of vibrations, but in some cases vibrations can transfer to other structures. A rubber mat placed under the appliance can absorb vibrations and noise (needed in special cases only). The thermostat has been set at the factory for ordinary operating circumstances. When installing refrigerated D-I models, special attention must be paid to condenser air circulation. Make sure that the condenser air inlet is not blocked and that warm air can freely exit the compressor compartment. The temperature of inlet air is of crucial importance to the cooling effect of the appliance.Ensure suffi cient air inlet/air circulation for the condenser.

Condenser air circulation Do not mount the condenser on a closed plinth, as this will prevent condenser air circulation. Air venting takes place below the appliance and air intake at the front. Do not block the condenser air inlets.

Opening for the drip basin (D-I models)
An opening must be made for the drip basin on the tabletop. The water cooler is installed inside the counter. The necessary openings are marked on the pictures with solid lines and the shape of the drip basin with broken lines.

Make a water connection between the faucet and the water cooler. Installation sequence:

1.  Assemble the faucet
2. Attach the faucet to the drip basin
3.  Attach the pipe connector to the faucet
4. Attach the pipe connector to the machinery outlet
5. Connect the faucet and the machinery outlet with a CU-pipe Ø 10 mm (not included in delivery)Connect the water cooler only to a cold water supply. A pressure reducer is needed if the water supply pressure is above 5 bar. The connection of the appliance to the water supply must be carried out by qualifi ed persons only.
   NOTE. Do not remove the spacer ring of the electronic faucet during installation!

Electrical connections
The appliance is designed to function in the electrical power network 1/N/PE AC 230V 50Hz. Connect the appliance to the power supply with an earthed socket.

First, start-up
The water tank of the cooler has to be fi lled before start up. Note that the water tank has to be fi lled manually, it does not fi ll even though the cooler is connected to the water supply. Fill the tank through the pipe located behind the front panel. Check the water level on the pipe. The tank volume i approx. 9 litres.

Adjusting the glass filling rate (mechanical faucet)

Water fi lling rate can be adjusted with the help of a screw located on top of the faucet by turning the screw with a screwdriver. If, after installation, some air comes out of the faucet, allow water to run until no air is coming and the water is clear.

Adjusting the electronic faucet for the glass used
To be performed by an authorized service technician or installer.

Adjusting the water fl ow (electronic faucet)
To be performed by an authorized service technician or installer.
