Precautions - dosatron D 25 F Manual De Utilización

Precise, simple and reliable
Installed directly in the water supply line, the DOSATRON operates
by using water pressure as the power source. Water activates
the DOSATRON, which takes up the required percentage of
concentrate. Inside the DOSATRON, concentrate is mixed with
water. Water pressure forces the solution downstream. The
dose of concentrate will be directly proportional to the volume
of water entering the DOSATRON, regardless of variations in
flow or pressure which may occur in the main line.

PRECAUTIONS

1- GENERAL REMARKS
- When connecting a DOSatRON
either to the public water supply
or to its own water source, you
must respect the regulations in
force concerning protection of the
source i.e. backflow prevention,
etc.
- When connecting the
DOSatRON to the water supply,
ensure that the water
flows in the direction of the arrows
on the unit.
- In a case where the water
installation is higher than
the DOSatRON itself, there
is a possible risk of water and
concentrate flowing back through
the DOSatRON. In this case,
installing a non-return valve
downstream is recommended.
- It is recommended that you
should place an anti-siphon valve
on the downstream side of the
dosing pump in installations in
which there is a risk of siphoning.
- Do not install the DOSatRON
just above an acid container,
(risk of acid fumes attacking the
DOSatRON) and protect it from
possible contact with corrosive
products.
- Protect the DOSatRON from
freezing temperatures by draining
it and store it away from sources

of excessive heat.
- Do not install the DOSatRON
on the suction side of the supply
pump (risk of siphoning).
- It is the responsibility of the
owner/operator to replace the
injection seals annually to ensure
precise injection.
- the setting of the Dosatron's
dosing rate is the sole responsibility
of the user. the user has to
respect the recommendations
given by the manufacturer of the
chemical product.
WARNING
You must comply with
the safety instructions
when installing, using and

dosing pump: use appropriate
tools, protective clothing and
safety goggles when working
on the equipment and install
the DOSATRON so that it can be
used without presenting a risk.
Follow the instructions in
this manual and take the
appropriate safety measures
for the water temperature and
the type of liquid being drawn
up. Take extreme care when
using dangerous substances
