DOSATRON Technology
A unique technology associating all dosing functions
Installed on the water supply line, the Dosatron uses water pressure
as the only power source. Thus activated, it takes up the required
percentage dose of concentrate and then mixes it with the moving
water. The solution produced is then propelled downstream. The dose of
injected product is always proportional to the volume of water passing
through the Dosatron, regardless of variations in flow or pressure in the
water supply line.

Installation
PRECAUTIONS
1-GENERAL POINTS
- 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 disconnector to
prevent contamination of the water
supply.
- When connecting the DOSATRON
to the water supply line, ensure that
the water flows in the direction of the
arrows shown on your appliance.
- In the case where upstream or
downstream water circuits are
higher than the Dosatron, there
is a possible risk of water and
concentrate flowing backwards.
Installing a non-return valve
downstream from the appliance is
therefore recommended.
- Placing 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 container of acid or
aggressive product. Move the can
away and protect it from possible
product fumes with a cover.
- Store the DOSATRON away from
excessive heat sources and in winter
away from frost.
- Do not install the DOSATRON on
the water pump suction circuit (risk
of siphoning).
- It is the responsibility of the user
to replace the dosing part seals
annually to ensure accurate dosing.
- The adjustment of the Dosatron’s
dosing is the sole responsibility of
the user. The user must adhere
strictly to the recommendations of
the manufacturer of the chemicals.
WARNING
When installing, operating, and
maintaining the DOSATRON
water-powered dosing pump,
as a priority observe the safety
instructions. Use suitable tools,
protective clothing, and safety
glasses when working on the
equipment and install it with
a view to ensuring risk-free
operation.
Follow the instructions in this
manual and take safety measures
appropriate to the nature of the
suctioned liquid and the water
temperature.Be extremely careful
in the presence of hazardous
substances (corrosives, toxic
substances, solvents, acids,
caustics, flammable substances,
etc.).

© DOSATRON INTERNATIONAL S.A.S / 12
- For dosing these substances,
please consult your distributor
before use to confirm
compatibility with the dosing
pump.
IMPORTANT! The personnel in
charge of the installation, use and
maintenance of this equipment
must have perfect knowledge of
the content of this manual.
the content of this manual.
- Ensure that the water flow and
pressure of the installation are
compliant with the DOSATRON
characteristics.
- Adjustment of the dosing must be
made unpressurised. Turn off the
water supply and allow the pressure
to drop to zero.
- It is the sole responsibility of the
user to select the DOSATRON
adjustments to obtain the desired
dosing.
- An airtightness problem, an
impurity or a chemical attack on
the seal can interrupt the dosing
operation. Periodic checking that the
concentrate to be dosed is being
correctly drawn into the DOSATRON
is recommended.
- Change the DOSATRON suction
hose as soon as it seems damaged
by the concentrate being dosed.
- Release the pressure after use
(advised).
- Rinsing of the DOSATRON is
essential:
• whenever the product is changed
• before handling the DOSATRON,
to avoid any contact with aggressive
products.
- All assembly and tightening
should be done manually without
tools (outside tightening torque
recommendations).
2-WATER WITH 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. 120 mesh - 130 microns
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.
- In the case where a DOSATRON
serves several sectors, activate
the solenoid valves simultaneously
(closure of one sector and opening
of another sector at the same time).
4-INSTALLATION LOCATION
- The DOSATRON and the product
to be dosed should be accessible.
- 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”.
PRECAUTIONS (cont...)

© DOSATRON INTERNATIONAL S.A.S / 12 © DOSATRON INTERNATIONAL S.A.S / 13
5-MAINTENANCE
- After use, the aspiration of clear
water is recommended.
- Annual maintenance will optimise
the life of your DOSATRON.
Annually replace the dosing part
seals and the product suction hose.
6-SERVICE
- This DOSATRON was tested prior
to packaging.
- Repair sub-assemblies and
sachets of seals are available.
- Do not hesitate to call your
distributor or DOSATRON for any
after-sales services.

THE INSTALLATION ASSEMBLY SHOULD BE CARRIED OUT WITHOUT
TOOLS
The DOSATRON is delivered with:
- a mounting bracket,
- a suction hose with a strainer.
The bracket enables the DOSATRON to be mounted on a wall.
Engage the DOSATRON dovetails into the mounting bracket.
Remove the protective caps which block the openings in your DOSATRON,
before connecting it to the water supply line. (Fig. 1)
RECOMMENDATIONS
The DOSATRON can be connected to the water supply line by means of 40 mm
interior diameter flexible pipes fixed with swivel fittings 1 1/2” [Ø 40 x 49 mm].
Ensure that the water flows in the direction of the arrows (water direction) on the
appliance.
Whenever possible, install the Dosatron high enough for easy reading and
adjusting of the dosing on the graduated scale in % or ratio.

The DOSATRON dosing rate can be adjusted according to two scales:
percentages and ratios. These scales are positioned on either side of the
dosing part (Fig. 2).
Depending on the liquid circulation direction in the hydraulic installation, and
on the direction in which the dosing pump is mounted on its bracket, it may
be necessary to change the orientation of this scale.
CHANGING THE DOSING SCALE
- Unscrew the fixing nut on the dosing part by hand to release it by
pulling downwards and rotating half a turn to see the correct dosing
adjustment scale (Fig. 3).

- If necessary, to see the pins better,
unscrew the dosing adjustment sleeve
as far as the middle of its travel.(Fig. 4)
- Manually retighten the fixing
nut on the dosing part(Fig. 5)

INSTALLATION TIPS
The DOSATRON must be assembled in by-pass as shown below (Fig. 8).
For installations using header tanks, make sure the minimum water pressure
is available for correct operation of the Dosatron (the lowest water level
height in relation to the drinking troughs).
If your flow is above DOSATRON limits, see the § OVERFLOW. To
prolong the service life of the DOSATRON, it is advisable to fit an upstream
filter (e.g. 300 microns - 60 mesh depending on your water quality). This
precaution is essential if the water contains impurities or particles, especially
if the water comes from a well or it is surface water.
The filter is recommended and necessary for the warranty to be valid.
