Instructions for use and maintenance
EN
Upon connecting the water heater to the water supply
system, take care of the indicative color markings /rings/
of the pipes:
BLUE - for cold /in-flowing/ water,
RED
- for hot /out-flowig/ water.
The mounting of the safety return-valve supplied with the
water heater is obligatory. The safety return-valve must
be installed on the cold water supply pipe, according to
the arrow stamped on its body that indicates the supplied
water direction.
Exception: If the local regulations (norms) require the
usage of another protection valve or mechanism (in
accordance with EN 1487 or EN 1489), then it must be bought
additionally. For mechanisms operating in accordance with
EN 1487 the announced operational pressure must be no
more than 0.7 MPa. For other protection valves, the pressure
at which they are calibrated must be 0.1 MPa lower than the
one marked on the appliance’s sign. In these cases the safety
valve which the appliance is supplied with should not be
used .
ATTENTION! Other type of stopping armature is not
allowed between the protection return valve (the
protective device) and the appliance.
ATTENTION! Any other /old/ safety return-valves may
lead to a failure of your appliance, therefore they
must be removed.
ATTENTION! Fixing the safety return-valve to threads
longer than 10 mm is not allowed, as it could
damaged the valve and could make the use of your
appliance dangerous.
ATTENTION! The safety valve and the pipe between
the valve and the water heater must be protected
from freezing. During hose draining - its free end must be
always open to the atmosphere (not to be immersed). Make
sure that the hose is also protected from freezing.
The boiler is filled with water by opening the tap on the
cold water supply system and the tap on the hot water
mixing faucet. After the filling process is complete, a
constant stream of water should flow from the water-
mixing faucet. Now you can shut the hot water tap on the
mixing faucet.
When you must empty the water heater, you should first
cut it off the power supply.
Draining procedure for boilers designed to be installed
UNDER SINKS:
1. Switch the boiler off the power supply network.
2. Dismantle the connecting water fittings from the
boiler.
3. Disassemble the boiler from its installation place, turn
it so the pipes point to the floor and pour the water in a
vessel you have prepared for the purpose. Wait until all
the water drains out of the boiler.
In case that the pressure in the water mains is over the
value pointed out in the above paragraph I, then it is
necessary to assemble a pressure reduce valve, otherwise
the water heater would not function properly. The
Manufacturer does not assume any liability for problems
arising out of the appliance’s improper use.
3. Water heater's electrical connection (fig.3)
ATTENTION! Before you switch the power supply,
make sure the appliance is full of water.
3.1. Models fit with power supply cord combined with a
plug
•
Swich on the plug to the correctly connected and
earthed socket
•
The socket must be connected to the electrical
network through a separate circuit, protected with fuse
16 A.
•
The electrical technician must check if the previous
requirements are fulfilled
The appliance should be positioned so that the switched
on plug to be easy accessible.
The water heater can be disconnected from the power
supply by unplugging.

V. OPERATING THE DEVICE
1. Включване на уреда
Before initial start of the device, please make sure that
the water heater has been correctly connected to the
electrical network and that it is filled up with water.
Clarification to
Fig.2 :
1 - Light indicator;
2 - Regulator knob – for temperature setting.
2.
Light indicator
Lamp IL1 is on when the boiler is switched on in water
heating mode. Lamp IL1 switches off when the water
reaches the preset temperature and indicates that the
appliance is not in operation.
3.
Temperature setup
This setup allows the gradual setting of the desired
temperature, achieved by using a handle on the control
panel. Turn the knob to the upward indication, in order to
increase the temperature of the hot water.
The "min" position on the knob does not protect the
appliance from freezing.
If the temperature in the room is likely to fall below
0° C, the appliance must be disconnected from the electrical
installation and drained.
WARNING! Once a month set the knob to the
position ‘maximum temperature’ for a period of 24
hours (unless the device is constantly operated in this mode).
Thus you will ensure better hygiene of the heated water.
