3. The unit can only be used when in perfect technical condition and correctly
installed.
4. If there is a non-return valve installed on the water supply pipe the safety valve
must be fitted between the unit and non-return valve.
5. Inlet and outlet pipes should not be made of plastic. This relates to KDH only.
6. 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

should be made by a qualified person.
8. The unit has to be earthed or neutrally grounded.
9. The unit must be permanently connected to the electrical system equipped with
an earth clamp.
10. 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).
11. 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.
12. It is not recommended to use mixer taps with thermostat.
13. The unit must be kept in a place in which the temperature never goes down below
0°C (there is a water inside the unit).

tings must be descaled on the regular basis, the frequency of limescale removal
depanding on the quality of water.
