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.
1 - GENERAL REMARKS(cont...)
Follow the instructions in this manual
and take additional safety measures
appropriate to the liquid being
pumped and the temperature of the
water that powers the DOSATRON.
Be extremely careful in the presence
of hazardous substances (e.g.
corrosives, toxins, solvents, acids,
caustic, flammables, etc.).
