Installation; Precautions - dosatron DIA 2 F Gebrauchsanweisung

Precise, simple and reliable
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.

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
Solution water
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).

Installation

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.
