Installation and usage tips

Multiphase or single-phase heaters may be terminated with clamps directly connected to the heating element, or with electrical cords terminated with clamps. In each case, the connection to the power supply must be executed by a trained installer who has the current qualifications of the Association of Polish Electrical Engineers (SEP) or an equivalent in a given country and appropriate knowledge in the field of electrics. Before installation, it is imperative to make sure that the source of electricity is turned off.

Boiler and modular heaters are equipped with thermostats with STB protection (German: Sicherheitstemperaturbegrenzer), i.e. a non-self-returning thermal fuse.
The fuse will work after exceeding a certain temperature and the heater will stop heating. In such a case, disconnect the heater from the power supply, remove the knob or plug by levering it gently, and then press the fuse button located next to the thermostat axis with a thin screwdriver. If you hear a click, the STB has been pressed. If no click is heard, please contact our technical department.

Not all our products have a gasket in the form of an o-ring as standard.
The solid installer is equipped with Teflon tape or tow (carded yarn) with a thread sealing paste.
The previously mentioned materials can also be purchased in almost any installation store.
