It is not the manufacturer's policy to make recommendations in terms of water treatment (please contact a
specialised water treatment company).
However, given the critical nature of this subject, particular care should be taken to ensure that, if treatment
is required, it works effectively.
Using untreated or unsuitable water leads to excessive clogging inside the coil tubes (earth and mud deposits,
corrosion, etc.) with major consequences on the thermal efficiency of the unit and irreversible damage to
the equipment.
The manufacturer and its representative decline all responsability in the event of untreated or incorrectly
treated water being used.
CAUTION
BEFORE CARRYING OUT ANY OPERATION ON THE EQUIPMENT,
CHECK THAT THE ELECTRICAL POWER SUPPLY IS SWITCHED OFF
AND THAT IT CANNOT BE SWITCHED ON INADVERTENTLY.
