Should the heat exhanger (heating water) in the water tank not be used for water heating, it
must be filled with an anti-freeze liquid, to prevent corrosion in the exchanger. Only close a
full exchanger at the bottom (equalisation of pressure due to temperature changes).
WARNING
Due to use of different materials on the pipe installation, all connections (cold
water, hot water, circulation, heat exchanger) on the device must obligatorily be
galvanically isolated, or the corrosion of connections within the heat storage may
occur. We recommend galvanic separators from red alloy for each attachment, at
least 2x pipe diameter in length.
WARNING
The water tank is intended for potable water so it must obligatorily comply with the
valid national regulations on potable water, or device damage may occur and the
warranty is nullified.
