Water heaters are equipped with a universal electric heating unit with either set or adjustable heating element

performance. A heating unit consists of a flange, to which one or three wells for ceramic heating elements and one

thermowell are welded (see fig.). A unit is attached by either 8 M 10 screws with a 168 mm clearance, or 12 M 12

screws with a 210 mm clearance. In the wiring plastic cover, there is a thermostat and a safety fuse; heater

operation control light; and a lead-in wire bushing.

The sensors must be inserted all the way in; first the thermostat and then the safety fuse.

The performance of heating unit may be adjusted based on either required heating time or connecting possibilities

of electric energy distribution in the place of use.

setting the service water temperature to maximum temperature of 60°C. This temperature ensures an optimal

operation of the heater, reduces heat losses and saves electricity. After reaching the temperature set, the thermostat
