instantaneous water heaters are designed to supply hot water to such
sanitary devices as sinks and washbasins in households, washrooms, bathrooms, workshops and
catering outlets. Thanks to the electronic system controlling the performance of the heater, all most
unreliable mechanical parts such as a membrane and switch contacts, which are used in this type
of heaters, have been eliminated. This way, the reliability and durability of the devices have been
significantly improved. The water heater can only be connected to the cold water pipe.
Caution!!! You mustn’t install, disconnect or move the heater to the sides
while the power supply is turned on. The device can operate only in the
position shown in the figure below. Any attempt to start the device in
other positions will cause damage to the heating element and the loss
of warranty.
2. Safety recommendations
– Only a qualified electrician can connect the device to the electrical wiring and check the ef-
ficiency of the anti electric shock protection.
– The heater must be earthed and neutrally grounded.
– The heater must be permanently connected to the electrical wiring.
– The wiring must be equipped with a residual current circuit breaker.
– The air temperature in the rooms where the heater is installed cannot decrease below 0
O
C.
– Periodically check the condition of the electrical wiring (voltage drops) – in particular the electri-
cal connection.
– Cut off the power supply before each disconnection of the heater from the faucet.
– The heater can operate only in the position shown in figure 1.
– The device can be used only when it is fully operational and it has been installed properly.
– In case of malfunctioning of the heater, cut off the power and water supply
– Do not take off the case when the device is connected to the power source.
– Water flow in the heater ought to be controlled in such a way that the water temperature does
not cause the feeling of heat (especially as far as children are concerned).
