shown to be defective in material or
workmanship during a period of twelve
months from the date of purchase by
the original purchaser.
To obtain warranty replacement of a
part, the DOSATRON must be returned
with original proof of purchase receipt
to the manufacturer or authorized
distributor and thereafter recognized
as defective after examination by the
technical services of the manufacturer
or distributor. The DOSATRON must
be flushed of any chemical and sent to
the manufacturer or distributor prepaid,
but will be returned free of charge once
repairs are made if found to be covered
by the warranty. Any repairs made
under warranty will not extend the initial
warranty period.
This warranty only covers circumstances
where the part has failed due to defects
caused by the manufacturing process.
This warranty is invalid if the defects are
found to be due to the product's misuse,
inappropriate use of tools, lack of
maintenance or defective installation or
environmental accidents or corrosion by
foreign bodies and liquids found within
or in proximity to the DOSATRON.
Before using any aggressive chemicals,
please consult your distributor to confirm
compatibility with the dosing pump.

of the DOSATRON for the warranty to
