Precise, simple and reliable
Installed directly in the water supply line, the DOSATRON opera-
tes by using water pressure as the power source. The water
activates the DOSATRON, which takes up the required percenta-
ge of concentrate. Inside the DOSATRON, the concentrate is
mixed with the water. The water pressure forces the solution
downstream. The dose of concentrate will be directly proportio-
nal to the volume of water entering the DOSATRON, regardless
of variations in flow or pres-
sure which may occur in
the main line.

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 sour-
ce i.e. backflow prevention, etc.
- In a case where the downstream
water installation is higher than the
DOSATRON itself, there is a possible
risk of water and concentrate flo-
wing back through the DOSATRON.
In this case, installing a check valve
downstream is recommended.
- 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 free-
zing temperatures by draining it and
store it away from sources of excessi-
ve heat.
- Do not install the DOSATRON on
the suction side of the supply pump
(risk of siphoning).
- During any intervention the opera-
tor 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 manu-
facturer of the chemical product.
- It is the responsibility of the
owner/operator to check that the
flow and pressure of the installation
do not exceed the DOSATRON cha-
racteristics.
- 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 chemi-
cal attack on a seal can interrupt the
dosing function. It is recommended
to periodically check that the solu-
tion 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
avoid any contact with the chemical.
