For the correct functioning of the electronic control and the operation of the water
heater it is necessary to use only the temperature sensors supplied in the set. If the sensors are
not installed or incorrectly installed, some of the mode menus will not be displayed on the

ANTI-CORROSION PROTECTION, PROPHYLAXIA, MAINTENANCE
Indoor unit with enamelled water tank.
In each water heater with an enamelled water tank, there is
built-in additional anti-corrosion protection. It consists of an anode made of a special alloy, working
only when the water tank is full of water. The anode is a consumable (element normally wearable
during appliance operation) and has an average life of up to 3 years. This period is strongly
dependent on the way the appliance is used and the characteristics of the water used for heating
After the expiration of this period, a specialist from the service companies authorized by the
manufacturer or seller will need to check the condition of the anode. If it is found necessary, the
anode should be replaced with a new one. Complying with the term and timely replacement of the
anode is an important condition for continuing the effective protection of the water tank from
corrosion. The evaluation and replacement of the anode is not subject to the warranty obligations of
the seller and the manufacturer.
Indoor unit with high-alloyed chrome-nickel steel water tank.
The corrosion protection and
guaranteed long service life are ensured by the properly selected steel, the suitable construction and
the technology of manufacturing the water tank.
For the reliable operation of the indoor unit in areas with calcareous water, it is recommended that
the water tank be cleaned from limestone. This should be done at least once in 2 years, and in areas
with very calcareous water even more often. The deposits on the enamel coating should not be
removed but only wiped with dry cotton cloth without the use of rigid tools. Regular removal and
cleaning of limestone is essential for the reliability of the appliance. It is desirable during this activity
to carry out a review of the anode of the enamelled water tank. These services are not subject to
warranty service and should only be performed by a specialist.
WARNING
! To ensure safe and trouble-free operation of the indoor unit, the combined valve
must be periodically checked that its permeability is not impaired. This is done by lifting its lever
and waiting for 30-60 seconds to run a dense and powerful stream of water from the side
opening of the valve. This must be done after connecting the indoor unit to the water supply
system and filling the water tank with water during the use of the indoor unit no less than once
every 2 weeks as well as after the water supply is stopped and renewed. If, when the water tank
is full, water does not flow through the valve opening or the flow is weak, this is a malfunction
and the valve may be blocked by dirt in the plumbing installation. The use of the indoor unit with
a faulty combined valve is strictly forbidden. Immediately disconnect the appliance from the
power supply and contact the nearest service company authorized by the manufacture.
Otherwise, you will cause damage to the water tank, and also damages to other objects and to
the premise where the indoor unit is placed may occur.
If there is any doubt that the temperature in the room where the indoor unit is installed may drop
below 0 ° C, the water from the water tank MUST be drained - see the section "Connecting the water
heater to the plumbing installation".
The outer casing and the plastic parts of the appliance can only be cleaned using lightly moistened
soft cotton cloth without the use of aggressive and / or abrasive substances and detergents. Before
cleaning the appliance, it MUST be disconnected from the power supply by means of the extra
disconnecting device or by removing the plug of the power supply cable. IT IS PROHIBITED to clean
the appliance with a steam generator. Particular care must be taken to prevent the moistening of the
