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.

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.).

- 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.

- 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. 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.

- 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...)

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 Ø 40 x 49 mm

[1 1/2”]. 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.

Tightening torque 30 N.m

i.e. 3 kg.m

(reminder: 1 N.m = 0.1 DaN.m)

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)

Fig. 3Fig. 2

- If necessary, to see the pins better,

unscrew the dosing adjustment sleeve

as far as the middle of its travel.

- Manually retighten the fixing

nut on the dosing part

Fig. 5

Fig. 4



The DOSATRON is delivered with a suction hose (to be adjusted as

necessary) enabling its use with a large capacity container. This hose must

be fitted with the strainer and ballast.

NOTE: The maximum suction height is 4 metres [13 ft].

CONNECTING THE SUCTION HOSE

- Unscrew the nut

(Fig. 6)

at

the bottom of the dosing

part and thread the suction

hose into the nut.

- Push the hose into the

barbed fitting as far as it

will go and screw the nut by

hand

(Fig. 7)

.

- Assemble the strainer on

the other end of the hose

using the same method

- Immerse the strainer into

the solution to be dosed

Fig. 6

Fig. 7

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.

INSTALLATION TIPS (continued)

The filter is recommended and required for the warranty to be valid.

IMPORTANT! Leave the strainer about 10 cm [4”] from the bottom of

the container of solution in order to prevent insoluble particles from

being aspirated. They may damage the dosing pump body. The strainer

must not rest on the bottom of the container.

For any installation on the drinking water supply line, respect the

standards and regulations in force in the country.

OVERFLOW (as an indication)

If your DOSATRON clacks more than 44 times in 15 seconds, (i.e. 22 cycles)

you are at the upper flow capacity limit. Beyond this select a DOSATRON with

a higher water flow capacity.

Under no circumstances should the

solution level be above the water inlet on

the DOSATRON (to prevent any siphoning)

(Fig.10).
