Precautions; General Remarks - dosatron D 25 F Manual De Utilización

Precise, simple and reliable
Installed directly in the water supply line, the DOSATRON opera-
tes by using water pressure as the power source. Water activates
the DOSATRON, which takes up the required percentage of
concentrate. Inside the DOSATRON, concentrate is mixed with
water. Water pressure forces the solution downstream. The dose
of concentrate 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.

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.
