Precise, simple and reliable
A unique technology associating all dosing functions
Installed directly in the water supply line, the DOSATRON operates
by using water pressure as the power source. The water activates the
DOSATRON, which takes up the required percentage of concentrate.
Inside the DOSATRON, the concentrate is mixed with the water. The
water pressure forces the solution downstream. The dose of concen-
trate 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).
IMPORTANT ! Use no tool or
metallic utensils.
- During any intervention the
operator must stay in front of the
DOSATRON and wear protective
eyewear and gloves.
- 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.
AVERTISSEMENT
When installing, operating, and
maintaining the DOSATRON water
powered metering pump, keep
safety considerations foremost. Use
proper tools, protective clothings,
and eye protection when working
on the equipment and install the
equipment with a view toward
ensuring safe operation.
