Water treatment

Before putting the unit into operation, clean the water circuit.
The evaporator must not be exposed to flushing velocities or debris released during flushing. It is recommended that a
suitably sized bypass and valve arrangement is installed to allow flushing of the piping system. The bypass can be used
during maintenance to isolate the heat exchanger without disrupting flow to other units.
Dirt, scales, corrosion debrits and other 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.
