toxic, caustic and inflammable
substances, etc.).
- For dosing of these
substances, consult with your
distributor before use in order
to confirm they are compatible
with your dosing pump.
A dosing pump with the option
'T' is required when installing
the DOSATRON on a hot-water
supply (60°C/140°F Max).
The higher temperature
increases the risk and danger of
the aforementioned substances.
It is strongly recommended
that you place signs on the
dosing pump and the hot-water
installation warning of this
risk and that you comply with
legislation in force.
WARNING! Personnel in
charge of installing, using and
maintaining this equipment

operator of the DOSATRON, to
determine the correct amount
of solution and injection ratio to
obtain the desired result.
- An air inlet, an impurity or a
chemical attack on seal can
interrupt the dosing function. It
is recommended to periodically
check that the solution is being
correctly drawn up into the
DOSATRON.
- Change the suction tube as
soon as it seems damaged by the
chemical.
- Relieve the pressure after use
(advised).
