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 (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.

After the heater is connected to electric network, the heating element starts heating water. The element is turned on
and off by a thermostat. Thermostat can be set as per your need within the range from 5°C to 74°C. We recommend
setting service water 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 switches off the electric
circuit and thus discontinues water heating. The control light signals if the element is in operation (light is on) or if it
is off (the light goes out).
When shutting the heater out for an extended period, in winter you can set the thermostat to the snowflake sign
preventing the water from freezing, or turn off the inlet of electricity to the heater.
Connection, repairs, and wiring inspections may only be implemented by company (person) authorised to such
activity. Expert connection must be confirmed on the warranty certificate.
The heater is connected to the electric network using a solid moving conductor with a switch that turns off all
network poles and the circuit breaker (protector).
Installations in bathrooms, laundromats, rest rooms and showers must comply with ČSN 33 2000-7-701.
The degree of protection of electric parts of the heater is IP 44.
Respect rules of protection against electrical injuries in accordance with ČSN 33 2000-4-41.
