Functions and Features
of Your Water Heater
Resistance To Corrosion
As the inner drum of your water heater
has been enameled after welding all the
parts including the water inlet and outlet
pipes, it is fully protected against corro-
sion. The heater resistance is protected
against corrosion with the Magnesium
anode.
Resistance to Water Pres-
sure
The inner drum of the water heater has
been tested under 12-bars pressure du-
ring the manufacturing process conside-
ring the mains water pressure.
Eective Heat Insulation
Your water heater is isolated using a 50
mm polyurethane heat insulation materi-
al between the main body sheet and the
water drum. Thank to this material, the
water in the drum will heat rapidly and
cool down slowly.
Limiting Thermostat
The limiting thermostat will disable the
resistance to ensure the security in case
of excessive temperatures in the drum or
failure of thermostat. Once the limiting
thermostat is enabled, please call the
authorised service to operate the appli-
ance again.
V-Automated Switch
You can switch your water heater ON
and OFF using the V-Automated switch.
V-Automated Switch acts as a fuse. It will
disconnect the product from the mains
in case of an electrical leakage or when
the product is switched o. The provided
V-Automated Switch should be installed
by an authorised service technician only�
Safety Valve
The safety valve is installed onto the cold
water inlet of the water heater. This valve,
which acts like a fuse in case of a water
cut, prevents the draining of the water
in the drum. Besides, in order to balance
the internal pressure, this valve will disc-
harge water from the drain tip in case of
overpressure in the drum.
Thermometer
After starting the appliance, the thermo-
meter indicator on the appliance will start
moving clockwise. Low water temperatu-
re is indicated with a single line while the
maximum water temperature is indicated
with 3 lines. Upon decrease in water tem-
perature, the indicator will move counter-
clockwise.
Operating
After your water heater has been instal-
led and made ready-to-use by the autho-
rised service, you can operate it by plug-
ging it into a wall socket or switching the
fuse on. When you want to turn o your
water heater, please unplug it or switch

14
o the fuse.
• Ensure that the water heater is filled
with water before initial use.
• Switch on the V-Automated switch.
• The resistance will run and the red
light will be on until the water tem-
perature reaches the constant tem-
perature determined by the manu-
facturer.
• After the water temperature has re-
ached the degree determined by the
manufacturer, the thermostat will di-
sable the resistance and the light will
go o.
• When the water temperature decre-
ases below the degree determined
by the manufacturer, the resistance
will be enabled again and heat the
water.
• Since the water in the reservoir will
cool down when you turn o the
appliance after using it, there will be
more power and time consumption
for the next heating process.
Practical and Useful
Information
• Sediments and limescale accumula-
ted at the below section of the water
heater will prevent direct contact
between the water and the heating
elements. Accumulation of sedi-
ments and limescale at the bottom
of the water drum should be preven-
ted. The water drum should be dra-
ined completely at regular intervals.
• Your water heater should be installed
away from appliances such as refri-
gerators and freezers. Otherwise,
the operation frequencies of these
appliances will increase.
• The appliance should be insulated in
order to prevent heat loss from the
tanks and assembly.
• The water heater should be located
a maximum of 6m away from the
point of use. Installation on a locati-
on further than 6 meters will cause a
drop in the eciency of heat trans-
fer. Also the water piping should be
insulated.
• If the appliance will not be used for
a long time, switch o the fuse and
disconnect the power supply.
Suggestions for Operation
• Do not place items -which may be
aected by the water leakage- under
the appliance.
• Take below precautions if you will
not use the product for a prolonged
time.
- Disconnect the product from the
mains supply.
- Switch o the water valves and dis-
connect the water connections.
Cleaning and Mainte-
nance
Disconnect from the electrical mains
prior to any operation.
• Install a transparent drain hose to the
drain output of the safety valve lo-
cated at the cold water input of the
water heater at a location away from
freezing.
• Pressure will increase with the opera-
tion of the water heater. Dripping of

15
water from the safety valve is normal.
• Drain water from the drum by set-
ting the safety valve latch to upright
position. To check the operation of
the safety valve, it is recommended
to set the latch to the upright po-
sition once a month to see if water
flows out.
• If water has been drained through
the safety valve, do not operate the
system until water comes from the
hot water tap.
• To get the optimum performance
from your electrical water heater
all the time, the limescale that may
form on the resistance due to the
hardness of the mains water and
high temperatures should be remo-
ved by the Authorised Service.
Recommendations on
Energy Saving
• To get a better performance from
your product, the heating element
(resistance) should be cleaned and
the anti-corrosive magnesium rod
should be replaced every 2 years.
Cleaning and replacement should
certainly be performed by an autho-
rized service.
• Anode and heater should be check
annually in regions with higher water
hardness.
