4 IMPORTANT WARNING

Connection of the inner vessel to HSW must comply with ČSN 060830, a safety valve has

to be fitted on the cold water inlet.

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.

We recommend checking and cleaning the inner vessel from scale and eventual replacement

of the anode rod after two years of operation. The anode life is theoretically calculated for two

years of operation; however, it changes with water hardness and chemical composition

in the place of use.

Prior to commissioning, we recommend that you run the heating circuit and any impurities

that are trapped in the filter clean, then the system is fully operational.

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.
