Water treatment
Before putting the unit into operation, clean the water circuit.
Dirt, scales, corrosion debrits and other material can
accumulate inside the heat exchanger and reduce its heat
exchanging capacity. Pressure drop can increase as well, thus
reducing water flow. Proper water treatment therefore reduces
