Water heater is equipped with a universal electric heating unit with either a set or adjustable heating
elements' performance (except OKCE 300 S/1 MPa). A heating unit consists of a flange, to which one or
three wells for ceramic heating elements and one thermowell are welded (viz. Figure 10, Figure 11, Figure
12). 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.
