. Remove the power cord plug of the heater outlet.
Open the hot water tap of the closes mixer in order to free the
pressure within the unit. Release the connections of the water
mains in the room from the unit pipes for cold and hot water.
Unhook the tank fastening screw and suspension plate and place
it lying on the rear over a sink or a vessel that can accommodate
the water flowing out of the tank. Wait until draining. Attention! The
escaping water may be hot - beware of burns!
WARNING!
When draining the water out of the water tank all
necessary precautions must be taken to prevent damages from
flowing out water.
WARNING!
IT IS ABSOLUTELY PROHIBITED TO SWITCH
ON POWER SUPPLY TO THE SYSTEM WHEN THE WATER
TANK IS PARTIALLY FILLED OR EMPTY OF ITS WATER
CONTENT! Do not forget to fill the tank with water before
putting it back into operation.
T
he water heater connection to the water supply system must be
performed only by qualified persons.
CONNECTION OF THE WATER HEATER TO THE
ELECTRIC SUPPLY
NETWORK
WARNING!
Do not proceed to connect the water heater to the
power supply network unless you have made sure that its water
tank is full with water! Check!
T
he water heater is competed with a protection degree for
electrocution - Class I.
C
onnecting the water heater to the power supply 230 V ~ is carried
out rotating the knob for the unit temperature anti-clockwise until it
stops and the Illuminated key switches in OFF position (pressed
the end marked "0"), has joined the plug on power his cord to the
upright and properly connected with protective contact terminals
type F or E (Schucco, French type). The wires from the electrical
2
circuit of the contact should be with section 2,5 mm each, and fuse
in the phase line is 10 A. The socket must be positioned so that it is
easily accessible after installation of the water heater to the wall
and connecting it to the water installation. The electric installation
to which the heater will be connected must be built in accordance
with the requirements of the applicable statutes and local
regulations in force.
O
nce the appliance is connected to the power supply grid check its
functionality.
WARNING!
Failure to comply with the requirements
concerning connection to the mains shall impede the appliance
safety, in which it is prohibited to use. Such consequences are
not within the scope of manufacturer or seller warranty liabilities
and shall be at the expense of the party, which has not observed
the present manual instructions.
O
nly qualified persons are entitled to connect the water heater to
the mains and to check its functionality.
USAGE OF THE
APPLIANCE
Your water heater is switched on in operating mode by pressing
the glowing key on its end marked "I" and rotating the knob for the
temperature clockwise. You may switch off the appliance by
pressing the end of the button of the glowing key marked "0".
Complete shutdown is done by subtracting the plug on the power
cord from the outlet.
L
ighting of the key when in switched on position indicates that the
water heater is operating and water is heating, while when the light
is off it indicates that the water has reached adjusted temperature
and the heater is switched off.
U
sing the knob the temperature to which it will heat the water may
be adjusted. The chart around the thermostat knob has a distinct
sector marked ECO. When the cursor of the knob is in the sector,
the water is warmed to an optimum temperature at which the heat
losses of the device are reduced and the reduced use of electric
energy. At the same time, the warm water is sufficient for normal
households. When a need for a large amount of mixed water is
required the thermostat knob is rotated in the direction of travel
counterclockwise to its maximum position, to reach the higher
temperature of the water in the tank. We recommend to keep the
knob in the sector ECO, when the heater is left on for long periods
without use of hot water and only to store heated water.
T
he appliance built-in thermostat unit has antifreeze function.
When the thermostat knob is to the extreme left, at the scale
beginning, the heater shall switch on at ambient temperature
around 8-10°C and shall switch off at about 12-15°C. Thus in case
of air temperature fall in the room, the water in the tank will be
protected from freezing. ATTENTION! This feature shall not
prevent the water in the room plumbing from freezing!
W
ithin the combined valve of the water heaters under pressure is
built a special controller which during water heater normal
operation allows the expanded during heating water not to leak
through the valve side hole, but to pass into cold water plumbing.
The quantity of this water is negligible and usually is with low
temperature. During normal operation of the water heater, as well
as in present of additional return valve, it is possible that through
the valve side opening leak some water drops. This should not be
perceived as defect and the side hole of combined valve should
not be blocked because it shall cause destruction of the tank. The
built-in controller in the valve prevents, in case of cutting water
supply, the water in the water tank to return to cold water pipeline.
D
uring the water warming in the water heaters with free outflow the
water expanded by temperature leaks from the fitting outlet. This is
not a defect! Do not try to stop the drip, as tightening the mixer
knobs - you can damage them!
WARNING!
Do never switch the appliance if there is a chance
that the water in the water tank is frozen! This shall damage
both heater and the tank.
W
hen the appliance is used in areas with soft water rich in limestone
it is possible to hear some noises during water heating. The noise is
due to the limestone stitching on the heater and contained within the
tank. The quantity of limestone contained depends of the type of
water and its heating temperature. When the latter is higher than
60°С the quantity of separate limestone increases. Accumulated
limestone impedes the heater efficiency and may even cause its
failure, while increasing the time for water heating.
W
hen using the appliance it is possible to hear some weak noise
due to the water flow through the pipelines and the appliance, as
well as to the natural process of expanding and heating.
W
hen the heater is regularly used to heat water to a lower
temperature, it is recommended to turn the thermostat knob at
least once monthly to its maximum position, then to heat the water
to maximum degrees and keep it such at least for 24 hours in order
to prevent bacteria formation.
