than 8°C–10°C it is advisable to clean the exchanger.
The clearing must be eected:

with circulation opposite to the usual one
t
with a speed at least 1,5 times higher than the nominal one
t
with an appropriate product moderately acid (95% water + 5% phosphoric acid)
t
after the cleaning rinse with water to inhibit the action of any residual product
