IN-WARRANTY RETURN MATERIAL PROCEDURE
Material must not be returned without permission of our After Sales Department.
To return the material, contact your nearest sales office and ask for a "return voucher". This return voucher shall be sent
out with the returned material and shall contain all necessary information concerning the problem encountered.
The return of the part does not constitute an order for replacement. Therefore, a purchase order must be entered
through your nearest distributor or regional sales office. The order should include part name, part number, model
number and serial number of the unit involved.
Following our personal inspection of the returned part, and if it is determined that the failure is due to faulty material
or workmanship, and in warranty, credit will be issued on customer's purchase order. All parts shall be returned to
our factory, transportation charges prepaid.
SERVICE AND SPARE PARTS ORDER

provided whenever service works or spare parts are ordered.
For any spare part order, indicate the date of unit installation and date of failure. Use the part number provided
by our service spare parts, if it not available, provide full description of the part required.
Take care
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.
