Safety instructions
1. Read and strictly follow the installation and operating instructions to ensure a long
life and reliable unit operation.
2. The unit is designed to be mounted only on the flat wall.
3. The water heater is designed to heat DHW in households, sanitary facilities,
laboratories and workshops etc.
4. The unit can only be used when in perfect technical condition and correctly
assembled.
5. If there is a non-return valve installed on the water supply pipe the safety valve must
be fitted between unit and non-return valve.
6. Inlet and outlet pipes should not be made of plastic.
7. The maximum inlet water temperature should not exceed 60°C.
8. The unit should always be vented before initial start-up. Vent the unit each time
after the water has been emptied from the heater or pipes (e.g. when water supply
system has been repaired or maintained).
9. Connection to the mains and measurement of fire protection effectiveness should
be made by a qualified person.
10. Water heater must be unconditionally connected to protective grounding- the quality
of which (continuity of the protective conductor) should be checked periodically
by qualified electrician. It is recommended to install heater on grounded, steel or
copper hydraulic fittings.
11. According to the general norms, electrical installation must be equipped with
current differential switch of high sensitivity (of max rated current 30 mA), whereby
we recommend installing a separate four-pole residual current circuit breaker
(regardless of the remaining part of the installation) of current 10 or 30 mA.
12. Electric installation should be equipped with residual current protective devices
and other solutions which will ensure disconnecting the heater from the source of
power (intervals between all their poles should not be less than 3 mm).
13. The unit must not be installed in the place which is exposed to the danger of
explosion and place in which the temperature may go down below 0°C.
