4 IMPORTANT NOTICES

We recommend to start up the heating circle before commissioning and to clean possible dirts

caught in the filter and after this the system would be fully functional.

Recommended operating pressure of hot water circle is 0.4 MPa. We recommend installing

return valve and an expansion vessel (min. 4 % of hot water in pipeline) on hot water outlet

to eliminate back pressure impacts.

The reservoir is possible to use only in compliance with conditions stated on performance plate

and with instructions for wiring. It is also necessary to observe terms for connection stipulated

by some local electrical and water companies as same as manual for assembling and operation

besides statutory accepted national regulations and standards.

Shut down the reservoir cold water intake if you are not using the reservoir for longer

than 24 hours or if the object with the heater is without presence of any person.
