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 wall mounted.
3.
The unit can only be used when in perfect technical condition and correctly
assembled.
4.
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. This relates to KDE only.
5.
Inlet and outlet pipes should not be made of plastic. This relates to KDE only.
6.
The maximum inlet water temperature should not exceed 60°C.
7.
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).
8.
Connection to the mains and measurement of fire protection effectiveness should
be made by a qualified person.
9.
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.
10. The unit must be permanently connected to the mains which is equipped with
earth clamp.
11. According to the general norms, electrical installation must be equipped with
current-diferential 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. 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.
13. Storage of water heater in the rooms where temperature drops below 0 degrees
may result in its damage (there is water inside the device) and may eventually
lead to the loss of warranty rights
