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.

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).
