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
the risk of corrosion, erosion, scaling, etc. The most
appropriate water treatment must be determined locally,
according to the type of system and water characteristics.
The manufacturer is not responsible for damage to or
malfunctioning of equipment caused by failure to treat water or
by improperly treated water.
