in material or workmanship during a
period of twelve months from the date

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

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,

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
