to be dosed
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 going through the Dosatron, regardless of variations in flow or
pressure in the water supply line (high variations in flow and pressure
driops as result of animal behaviour during drinking).

Installation
PRECAUTIONS
1-GENERAL REMARKS
- When connecting a DOSATRON
either to the public water supply line
or to its own water source, you must
respect 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 a 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
chemical 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 suction circuit of a water
pump (risk of siphoning >
consult Dosatron for this type of
installation).
- 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 strictly
adhere to the recommendations
from the manufacturer of the
concentrated additives.
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 toward ensuring safe
operation.
Follow the instructions in this
manual BEFORE USING FOR
THE FIRST TIME OR AFTER
A PERIOD OF NON-USE. Let
the DOSATRON operate for
30 CYCLES (motor + dosing
part) with clear water. Do not
drink the aforesaid water. 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
(corrosives, toxic substances,
solvents, acids, caustics,
flammable substances, etc.).

© DOSATRON INTERNATIONAL S.A.S / 13
- 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 soler responsibility of the
user to select the DOSATRON
adjustments to obtain the desired
dosing
- An air tightness problem, an
impurity or a chemical attack on
the seal can interrupt the correct
dosing operation. Periodic checking
that the concentrate to be dosed
is being correctely 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.
2-WATER WITH HIGH PARTICLE
CONTENT
A filter sieve must be installed
upstream of the DOSATRON when
water has a high particle content
(e.g. 300 mesh - 60 microns
depending on your water quality) If
this filter is not installed, abrasive
particles will cause the DOSATRON
to wear prematurely.
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).
PRECAUTIONS (cont.)

© DOSATRON INTERNATIONAL S.A.S / 13 © DOSATRON INTERNATIONAL S.A.S / 14
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: “IMPORTANT!
Nonpotable water”.
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 sealss are available.

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.
Place the DOSATRON in the bracket by spreading its arms slightly to click in
the 4 pins of the pump body (Fig. 1-A) fitting the two pins on one side of the
body (Fig. 1-A) into the corresponding holes in the bracket (Fig. 1-B).
Remove the plastic caps, (Fig. 1-C) which block the openings in your
DOSATRON, before connecting to the water supply line.
RECOMMENDATIONS
The DOSATRON can be connected to the water supply line by means of
20 mm interior diameter flexible pipes fixed with swivel fittings Ø 20 x 27 mm
[3/4”]. Make certain that the water flows in the direction of the arrows (water
flow) 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. Depending on the water 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.
- Lift the quick coupling ring
(patented system) and unlock the
dosing part by unscrewing the
ring as far as the mechanical stop
(approx. 1/8th of a turn) (Fig. 2).
- Pull downwards and rotate a halfturn
to release the dosing part to
see the correct dosing adjustment
scale.
- Insert the dosing body into the
pump body taking care to align the
aligning pins.
- If needed, to see the pins better,
unscrew the dosing adjustment
sleeve so as far as the middle of its
travel. (Fig.3).
- Push the quick coupling ring

INSTALLATION TIPS
OVERFLOW (as an indication)
If your DOSATRON clacks more than 40 times, in 15 seconds, (i.e. 20 motor
cycles) you are at the upper water flow capacity limit. Beyond this select a
DOSATRON with a higher water flow capacity.
The DOSATRON must be assembled in by-pass as shown belown (Fig. 9).
For installations using header tanks, be sure to have the minimum water
pressure 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 working life of the DOSATRON, it is advisable to install a filter
(e,g, 300 mesh - 60 microns depending on your water quality) upstream of the
DOSATRON. This is imperative if the water contains impurities or particles,
especially if the water comes from a well or it is surface water.
A filter is required for the warranty to be valid.
Installing the DOSATRON on a by-pass enables clear water to be supplied to
the installation without operating the DOSATRON and enables it to be easily
dismantled.
For any
installation on
the drinking
water supply
line, respect
the standards
and regulations
in force in the
country.
