Dosatron TECHNOLOGY
Unique technology incorporating all dosing functions.
DOSATRON is fitted directly to the water supply system and uses
water pressure as its power source. When activated in this way, it
takes up the required dose of concentrate and then mixes it with the
motive 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
- When connecting a Dosatron either
to the public water supply line or to
its own water source, it is essential to
conform to the standards concerning
protection and disconnection for
the country in which the appliance
is installed. Dosatron recommends
fitting a backflow preventer to avoid
contaminating the water supply.
- When connecting the Dosatron to
the water supply system, ensure that
the water flows in the direction of the
arrows shown on your appliance.
- 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. Installing a non-return
valve downstream of the appliance is
therefore recommended.
- 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
container of acid or any aggressive
products. Place the container to
the side and cover it to avoid any
product fumes.
- Keep the Dosatron away from
excessive heat sources, and protect
it from frost in winter.
- Do not install the Dosatron on the
suction side of the motive water
pump (risk of siphoning).
The user has sole responsibility
for replacing the dosing assembly
seals on an annual basis to ensure
accurate dosing.
The user has sole responsibility for
the adjustment of the Dosatron’s
dosing rate. The user must adhere
strictly to the recommendations of the
manufacturer of the chemicals used.
WARNING
During the installation, operation
and maintenance of the Dosatron
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.
Follow the instructions in this
manual and take safety measures
appropriate to the nature of the
liquid additives and the water
temperature. Be extremely
cautious in the presence of
dangerous substances (corrosive,
toxic, dissolving, acids, caustic
substances, inflammable
substances, etc.).

© DOSATRON INTERNATIONAL S.A.S / 12
- Before injecting these
substances, please consult
your distributor to confirm their
compatibility with the dosing
pump.
IMPORTANT! The personnel in
charge of installing, operating
and maintaining this equipment
must be fully acquainted with the
contents of this manual.
Ensure that the water flow and
pressure of the installation are
compliant with the Dostatron’s
specifications.
- The dosing adjustment must be
carried out with no pressure in the
system. Turn off the water supply
and allow the pressure to drop to
zero.
- The user has sole responsibility
for choosing the correct Dosatron
settings to obtain the desired dosing
rate.
- Problems with airtightness,
impurities or chemical aggression
of the seal can disrupt the dosing
operation. You are therefore advised
to check periodically that the
concentrate to be dosed is being
correctly drawn into the Dosatron.
- Change the Dosatron suction hose
as soon as it seems damaged by
the concentrate being dosed.
- Release the pressure in the system
after use (recommended).
- Rinsing of the Dosatron is
essential:
. whenever the product is changed
. before each intervention on the
Dosatron, to avoid any contact with
aggressive products.
- All assembly and tightening
operations should be carried out
using the appropriate tools, or
manually without tools (unless there
are specific recommended tightening
torques).
2-PARTICLE-LADEN WATER
- In the case of heavily particle-laden
water, a filter (e.g. 200 to 120 mesh
- 80 to 130 microns depending on
the quality of your water) MUST be
installed upstream of the Dosatron.
If this filter is not installed, abrasive
particles will cause premature wear
in the Dosatron.
3-WATER HAMMER / EXCESS
FLOW
For installations subject to water
hammer, a water-hammer arrestor
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 serves several
sectors, activate the solenoid valves
simultaneously (closure of one
sector and opening of another sector
at the same time).
PRECAUTIONS (continued)

© DOSATRON INTERNATIONAL S.A.S / 12 © DOSATRON INTERNATIONAL S.A.S / 13
4-LOCATION OF THE
INSTALLATION
- The Dosatron and the dosing
additive must be accessible at all
times. Their installation must not,
under any circumstances, pose a
pollution or contamination risk.
The marking of all water pipes
with notices bearing the statement
“CAUTION! Non-potable water” is
recommended, to indicate that the
water contains additives.
5-MAINTENANCE
- After use, the aspiration of clean
mains water through the system is
recommended.
- Annual maintenance will optimise
the service life of your Dosatron.
Replace the dosing assembly seals
and the product suction hose on an
annual basis.
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 service requirements.

The Dosatron’s dosing rate can be adjusted according to two scales:
percentage- and ratio-based. These scales are positioned on either side of
the dosing assembly (Fig.2).
Depending on the direction of flow in the hydraulic system and 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 VIEW

INSTALLATION ADVICE
The Dosatron should be installed in a full hydraulic bypass.
An in-line installation is possible but not recommended because it does not
enable the dosing pump to be easily isolated for maintenance (the water
supply must be turned off).
A by-pass installation enables the system to be supplied with clean mains
water when the Dosatron is not operating and enables it to be easily
dismantled.
If your flow rate is above the specified limits for the Dosatron, see
§ EXCESS FLOW.
To prolong the Dosatron’s service life, it should be fitted with an upstream
filter (e.g. 200 to 120 mesh - 80 to 130 microns, depending on the quality of
your water).
This precaution is essential if the water contains impurities or particles,
especially if the water comes from a well or if it is surface water.
Fig. 9
EXCESS FLOW (for information)
If your Dosatron clicks more than 44 times in 15 seconds, (i.e. 22 cycles)
you are beyond the upper flow-capacity limit.
