Do not use deionised cooling water.
To clean the heat exchanger : it is recommended to clean at least twice a
year the water circuit.
For that, dismantle the exchanger from the pump. Chemical cleaning is the
most efficient, with dilute hydrochloric acid solution (5 to 10%) then neutralize
with hexamethylethyrene tetramine at 0.2 %. For a 1 mm coat of scale, leave
acting the acid during about 30 min.
The system must be open during the operations, so the product gases can
escape. Rinse copiously with water after neutralization.
Proceed in an open and well ventilated place.
Observe the safety regulations given by the manufacturer of the product you
are using.
Observe the regulations for the treatment and the disposal of chemical
products.
Observe the relevant environmental regulations.
