DOSATRON Technology

A unique technology associating all dosing functions

Installed directly in the water supply line, the DOSATRON operates

by using water pressure as the power source. The water activates the

DOSATRON, which takes up the required percentage of concentrate.

Inside the DOSATRON, the concentrate is mixed with the water. The

water pressure forces the solution downstream. The dose of concen-

trate will be directly proportional to the volume of water entering the

DOSATRON, regardless of variations in flow or pressure which may

occur in the main line.

Installation

PRECAUTIONS

1-GENERAL REMARKS

- When connecting a DOSATRON

either to the public water supply or

to its own water source, you must

respect the regulations in force

concerning protection of the source

i.e. backflow prevention, etc.

- When connecting the DOSATRON

to the water supply, ensure that the

water flows in the direction of the

arrows on the unit.

- In a case where the water

installation is higher than the

DOSATRON itself, there is

a possible risk of water and

concentrate flowing back through the

DOSATRON. In this case, installing

a non-return valve downstream is

recommended.

- It is recommended that you should

place an anti-siphon valve on the

downstream side of the dosing pump

in installations in which there is a

risk of siphoning.

- Do not install the DOSATRON just

above an acid container, (risk of acid

fumes attacking the DOSATRON)

and protect it from possible contact

with corrosive products.

- Protect the DOSATRON from

freezing temperatures by draining

it and store it away from sources of

excessive heat.

- Do not install the DOSATRON on

the suction side of the supply pump

(risk of siphoning).

IMPORTANT ! Use no tool or

metallic utensils.

- During any intervention the

operator must stay in front of the

DOSATRON and wear protective

eyewear and gloves.

- It is the responsibility of the owner/

operator to replace the injection

seals annually to ensure precise

injection.

The setting of the Dosatron’s dosing

rate is the sole responsibility of

the user. The user has to respect

the recommendations given by

the manufacturer of the chemical

product.

AVERTISSEMENT

When installing, operating, and

maintaining the DOSATRON water

powered metering pump, keep

safety considerations foremost.

Use proper tools, protective

clothings, and eye protection

when working on the equipment

and install the equipment with

a view toward ensuring safe

operation.

Follow the instructions in this

manual and take additional

safety measures appropriate to

the liquid being pumped and the

temperature of the water that

powers the DOSATRON.

MANUAL NOTICE D40.indd 14 21/09/2016 22:03

- Be extremely careful in

the presence of hazardous

substances (e.g. corrosives,

toxins, solvents, acids, caustic,

flammables, etc.).

- Before applying any aggressive

chemicals, please consult

your distributor to confirm

compatibility with the dosing

pump.

IMPORTANT !

It is the responsibility of the

owner/operator to check that

the flow and pressure of the

installation do not exceed the

DOSATRON characteristics.

- Adjustmentmust be made

when there is no pressure in the

Dosatron. -Turn off the water

supply and allow the pressure to

drop to zero.

- It is the responsibility of

the owner/operator of the

DOSATRON, to determine the

correct amount of solution and

injection ratio to obtain the desired

result.

- An air inlet, an impurity or a

chemical attack on seal can

interrupt the dosing function. It

is recommended to periodically

check that the solution is being

correctly drawn up into the

DOSATRON.

- Change the suction tube as

soon as it seems damaged by the

chemical.

- Relieve the pressure after use

(advised).

- Rinsing of the DOSATRON is

required :

. when changing chemicals,

. before handling the DOSATRON,

to avoidany contact with the

chemical.

- All assembly should be done

without tools, hand tighten only.

2 - WATER WITH HIGH

PARTICLE CONTENT

- A (ex.: 60 microns - 300 mesh

depending on your water quality)

water filter must be installed

upstream from the DOSATRON

(see accessories), if a filter is

not installed abrasive substances

will cause the DOSATRON to

deteriorate prematurely.

3 - WATER-HAMMER /

EXCESSIVE FLOW

- For installations subject to water

hammer a protection device such

as a check valve or union ball

check must be fitted (pressure/flow

control system).

- For automatic installations, slow

opening and closing solenoid

valves are preferable.

- In an installation where a

DOSATRON serves several

sectors, the closing of one sector

and the opening of another sector

must be done at the same time

(simultaneous operation of the

solenoid valves).

4 - INSTALLATION LOCATION

- The location of the DOSATRON

and concentrate container should

be accessible, but should never

PRECAUTIONS (cont...)

MANUAL NOTICE D40.indd 15 21/09/2016 22:03

US

present a risk of pollution or

contamination.

- It is recommended to label all

water lines with a warning about

the injected solution i.e.

IMPORTANT ! Not For Human

Consumption.

5 - MAINTENANCE

- Rinse the injection areas after

using the DOSATRON. To do this,

insert suction tube into a container

of clean water and inject about

1/4 liter

[8 1/2 US Fl.oz].

- Routine maintenance once a

year will add to the life of your

DOSATRON. Replace the injection

seals as well as the suction

hose annually to ensure proper

injection.

6 - SERVICE

- This DOSATRON was tested

prior to packaging.

- Complete maintenance and seal

kits are available.

- Call your DOSATRON distributor

for service or parts.

The DOSATRON is delivered with a suction tube (cut it to the needed

length) enabling its use with a large capacity concentrate container.

The tube must be fitted with its strainer and weights.

The instructions for fitting the tube are to be found in the specific chapter.

NOTE : The maximum suction height is 13 vertical feet (4 meters).

Fit the tube, equipped with its strainer and its weight, and immerse it in the

solution to be injected.

ASSEMBLY SHOULD BE CARRIED OUT WITHOUT THE USE OF TOOLS

The DOSATRON is delivered with :

- a mounting bracket,

- a suction tube with a strainer.

The bracket enables the DOSATRON to be fixed to a wall.

Snap the DOSATRON into the bracket by fitting the two lugs on one side of

the body (Fig. 1-A) into the corresponding holes in the bracket (Fig. 1-B), and

springing the bracket arms apart until the other 2 lugs click into place.

Remove the plastic caps (Fig. 1-C) which block the inlet and outlet of your

DOSATRON before connecting to the water supply.

Torque 30 N.m

thus 3kg.m

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

RECOMMENDATIONS

The DOSATRON can be connected to the water supply by means of

Ø 1 1/2” [40 x 49 mm]bore flexible hose and hose tail fittings with hose clips.

Make certain that the water flows in the direction of the arrows on the motor

body.

MODEL D40WL3000IE

This model of Dosatron is supplied with an external injection pipe. Remove the

external protective plugs which seal the orifices of your DOSATRON and your

external injection kit.
