Installation; Precautions - dosatron D 8 RE 2 Manual De Utilización

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
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 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).

- 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.
Be extremely careful in
the presence of hazardous
substances (e.g. corrosives,
toxins, solvents, acids, caustic,
flammables, etc.)
