You have just acquired a DOSATRON water-powered dosing pump.
Congratulations on your choice. This model was produced using over 50
years of experience.
Our engineers have developed the DOSATRON series to become one of
the most technically advanced water-powered dosing pumps in the
world.
Over time, this DOSATRON will prove itself to be a most faithful ally.
A few regular maintenance operations will guarantee operation in which
the word “breakdown” will no longer be heard.
IT IS THEREFORE IMPORTANT TO READ THIS MANUAL
CAREFULLY BEFORE USING THE DEVICE.
Important!
You will find your DOSATRON’s part number and serial number
on the pump body.
Please record these numbers in the space provided below for
easy referral when contacting or requesting information from
your vendor.

DOSATRON
Technology
Unique technology that incorporates all dosing functions.
Installed on the water supply line, the DOSATRON uses water pressure as
the only power source. When activated, it draws in the concentrate, doses it
to the desired percentage, and mixes it with the motive water. The resulting
solution is then propelled downstream. The dose of injected concentrate is
always proportional to the volume of water flowing through the
DOSATRON, regardless of variations in flow or pressure in the water supply
line.

the dosing indication, have been awarded two different certifications regarding
their suitability for contact with water intended for human consumption:
•the NSF 61 & 372 certification (countries concerned: United States &
Canada). As such, they are certified for use with calcium hypochlorite in
concentrations of up to 65% and sodium hypochlorite in concentrations of up
to 15%. The treated water temperature should not exceed 23°C.
•the ACS certification (Drinking water certification - country concerned:

Installation
PRECAUTIONS
1. General points
WARNING: During the installation, operation and maintenance of the
DOSOTRON water-powered dosing pump, the following safety instructions
must be observed: use suitable tools, protective clothing and safety goggles
when working on the equipment and install it in such a way as to ensure risk-
free operation.
WARNING: Follow the instructions in this manual and take safety measures
appropriate to the nature of the liquid additives and the water temperature. Be
extremely careful in the presence of hazardous substances (corrosives, toxic
substances, solvents, acids, caustics, flammable substances, etc.). For dosing
these substances, please consult your distributor before use to confirm com-
patibility with the dosing pump.
ATTENTION! The personnel in charge of installing, operating and maintain-
ing this equipment must be fully acquainted with the contents of this manual.
•When connecting a DOSATRON either to the public water supply line or to
its own water source, it is essential to adhere to the standards concerning
protection and disconnection. DOSATRON recommends a shut off valve to
prevent contamination of the water supply, where applicable.
•When connecting the DOSATRON to the water supply line, ensure that the
water flows in the direction of the arrows shown on your device.
•If the system is located at a higher level than the DOSATRON itself, there is
a possible risk of water and concentrate flowing back into the DOSATRON.
We therefore recommend installing a non-return valve downstream of the
device.
•Fitting an anti-siphoning valve downstream of the dosing pump is
recommended in installations where there is a risk of siphoning.
•Do not install the DOSATRON above a tank containing aggressive additives.
Move the can away and protect it from possible product fumes with a cover.
•Keep the DOSATRON away from significant heat sources and away from
frost in the winter.
•In winter, or whenever the DOSATRON is exposed to temperatures close to
or below 0°C, it must be protected from the cold and frost.

/18
•Do not install the DOSATRON on the water pump suction circuit (risk of
siphoning).
•The user is responsible for replacing the injection seals once a year to
ensure accurate dosing.
•The adjustment of the Dosatron’s dosing is the sole responsibility of the user.
The user must strictly adhere to the recommendations of the chemical
manufacturer.
•Ensure that the water flow and pressure of the installation are compliant with
the DOSATRON specifications.
•The dosing should be adjusted with no pressure in the system. Turn off the
water supply and allow the pressure to drop to zero.
•The user shall be solely responsible for correctly adjusting the DOSATRON
to achieve the desired dosing rate.
•Problems with airtightness, impurities or chemical aggression of the seal can
disrupt the dosing operation. We therefore recommend that you periodically
check that the concentrate to be dosed is being correctly drawn into the
DOSOTRON.
•Change the DOSATRON suction hose as soon as it appears to be damaged
by the concentrate being dosed.
•Release the pressure in the system after use (recommended).
•The DOSOTRON must be rinsed:
−whenever the concentrate is changed
−before handling the DOSATRON, to avoid any contact with aggressive
concentrates.
•All assembly and tightening operations must be done by hand and without
the use of tools (except for those with recommended tightening torques).
2. Water with a high particle content
If the water has a high abrasive particle content which could cause premature
wear of the Dosatron, it is essential to install an upstream filter (e. g 130
microns - 120 mesh or finer).
3. Water hammer / Overflow
•For installations subject to water hammer, a water hammer protection device
must be fitted (pressure/flow control system).
•For automated installations, it is preferable to use slow opening and slow
closing solenoid valves.
•If a DOSATRON is used to supply several sectors, activate the solenoid
valves simultaneously (close one sector and open another sector at the
same time).

/19
4. Installation location
•The DOSATRON and the dosing additive must be accessible at all times.
Their installation must under no circumstances present a pollution or
contamination risk.
•It is recommended that all water pipes are marked showing that the water
contains additives and with the wording: “CAUTION! Non-potable water”
This wording will not be needed for drinking water applications.
5. Maintenance
•After use, we recommend flushing with clear water.
•Annual maintenance will extend the service life of your DOSATRON.
Replace the dosing seals and the additive suction hose at least once a year.
6. Service
•This DOSATRON was tested prior to packaging.
•Replacement sub-assemblies and packs of seals are available upon
request.
•Do not hesitate to call your distributor or DOSATRON for any after-sales
services.

/20
INSTALLING THE DOSOTRON
ATTENTION! THE INSTALLATION SHOULD BE CARRIED OUT
WITHOUT TOOLS
Remove the protective caps which block the openings in your DOSATRON,
before connecting it to the water supply line.

Make sure you follow the direction of fluid flow as shown by the arrow on the
pump body (see the bubble in the figure above).
