Limited warranty
DOSATRON INTERNATIONAL S.A.S.
will provide for replacement of all
parts shown to be defective in mate-
rial 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 dis-
tributor 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 circumstan-
ces 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 compati-
bility with the dosing pump.

DOSATRON caused by water impu-
rities such as sand. A filter (ex.: 300
mesh - 60 microns depending on your
water quality) must be used in front of
the DOSATRON for the warranty to be
valid. DOSATRON INTERNATIONAL

with the operating instructions and
tolerances as indicated in this owner's
