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.

US

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.

US

- 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.: 300 mesh - 60 microns

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...)

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

8 1/2 US Fl.oz [1/4 liter].

- 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.

US

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.

MODEL D14WL3000IE

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.

WARNING: do not use excess force when screwing the elements together.

CONNECTING THE EXTERNAL INJECTION (IE)

US

IMPORTANT ! - Do not put the suction tube strainer on the bottom of

the stock solution container. The strainer must be suspended at least 4”

[10cm] above the bottom of the tank to avoid sucking up the insoluble

particles that may damage the injection assembly (Fig. 2).

- Do not put the strainer on the ground.

Under no circumstance should the solution level be above the water

inlet of the DOSATRON (to avoid siphoning situations) (Fig. 3).

EXCESSIVE FLOW (as an indication)

If your DOSATRON clicks more than 46 times in 15 seconds (that is 23 cycles),

you are close to the superior flow limit. If you need more flow, you must install a

DOSATRON with a superior capacity of flow.

The DOSATRON can be connected

to the main water line directly

(Fig. 4) ; on a by-pass (Fig. 5),

recommended.

If your flow rate is above the

operating limits of the DOSATRON,

see EXCESSIVE FLOW.

To prolong the working life of the

DOSATRON it is advisable to install

a filter (ex.: 300 mesh - 60 microns

depending on your water quality)

upstream.

This is imperative if the water

contains impurities or particles,

especially if the water comes from

a well.

A filter is recommended and

required for the warranty to be

valid.

Installing the DOSATRON on a

bypass enables clean water to

be supplied without operating the

DOSATRON and the DOSATRON to

be easily dismantled.

When connecting an

installation to the public water

supply, you must respect the

rules and regulations in force

in the country.

Putting the DOSATRON

into order

USING FOR THE FIRST TIME

USE

NOTE: The time required to prime the suction tube

depends on the water flow-rate, the ratio setting

and the length of the suction tube. To bleed the air from the suction

tube and accelerate the priming, set the injection rate at maximum.

Once the DOSATRON is primed, adjust to the required injection rate

(see § ADJUSTING THE INJECTION RATE).

The device is designed to operate with fluids the temperature of which must

not exceed 40°C* (engine fluid, additive, engine fluid/additive mixture). In

the event of installation subject to operating at temperatures less than 5°C,

protect the installation from frost (see precautions instructions). The dosers

are designed for use up to 6 bars. The installation must be protected against

any overpressure risk. The installation must also be sized to avoid any

oscillating hydraulic phenomenon (water hammer). If necessary an anti-water

hammer device should be fitted.

*Certification: see codification paragraph.

- Partially open the water inlet valve.

- Press the bleed button on the top of the DOSATRON

(Fig. 6).

- When a constant flow of water is seen coming from around

the bleed button (no more «spitting» of air), release the

button.

- Open the water inlet valve slowly, the DOSATRON

is self-priming.

- Operate the DOSATRON until the product to be

injected is drawn up into the doser body (the product is

visible through the plastic tube).

- The DOSATRON makes a characteristic “click-

clack” noise when working.

ADJUSTING THE INJECTION RATE (with pressure off)

DOSAGE PRINCIPLE

BY-PASS OPTION

IMPORTANT ! Use no tools.

Adjustment must be made when there is no pressure in the DOSATRON.

- Turn off the water supply and allow the pressure to drop to zero.

- Unscrew the blocking ring (Fig. 7).

- Screw or unscrew the adjusting nut in order to line up the 2 peaks of the

eyelet with the desired ratio on the scale (Fig. 8).

- Tighten the blocking ring (Fig. 9).

Principle : Setting at 1% - 1/100 = 1 part of concentrate for 100 parts of water.

The DOSATRON may be fitted in its upper part with the function by-pass

(optional equipment) :

- By-pass in ON, the DOSATRON works and the concentrate is drawn up.

- By-pass in OFF, the DOSATRON is stopped and does not draw up the product.

Maintenance

RECOMMENDATIONS

1 - When using soluble products

to be made up into solutions, we

recommend the periodic dismantling

of the entire dosing part (see : §

CLEANING AND REFITTING THE

SUCTION VALVE, § CHANGING

SEALS IN THE INJECTION

ASSEMBLY).

Thoroughly rinsing all the elements

of the dosing part with water and

re-assembling them after having

previously lubricated the seal

(Fig. 10) with a silicone lubricant, in

the case of difficulty in re-fitting.

2 - Before putting the DOSATRON

into operation after a non-use

period, remove the motor piston and

soak it into lukewarm water

< 104° F [40° C] overnight. This

helps to dissolve any deposits which

may have dried onto the piston

motor.

HOW TO DRAIN THE DOSATRON (in case of freezing temperature)

- Turn off the water supply and let the pressure drop to zero.

- Remove the injection assembly, see § CHANGING THE MOTOR PISTON.

- Remove the bell and the motor piston.

- Disconnect the water inlet and outlet fittings.

- Remove the lower pump body from the mounting bracket and empty any

remaining water.

- The DOSATRON can now be reassembled, having first cleaned the seal.

CHANGING SEALS IN THE INJECTION ASSEMBLY (with pressure off)

Frequency : Once per year.

IMPORTANT ! Use no tool or metallic utensils

ADVICE: Before dismantling any part of the injection assembly it is

advisable to operate the DOSATRON, injecting clean water so as to rinse

through the injection system. In this way, risks of contact with concentrated

solutions in the injection assembly are minimized.

During any such intervention, wear protective eyewear and gloves !

METHOD OF REMOVING SEAL

Fig. 15 : Between finger and thumb, pinch the component and the seal ;

push towards one side to deform the seal.

Fig. 16 : Increase the deformation to grip the part of the seal thus exposed

and pull it out of its groove.

Clean the seal seating without any tools.

Refitting is done by hand.

It is very important that the seal is not twisted once in place as this would

impair its efficiency.
