Installation Hints - dosatron DI 1500 Manual De Utilización

ASSEMBLING THE DOSATRON (cont...)
IMPORTANT ! - Do not put the suction tube strainer on the bottom of the
stock solution container. The strainer must be suspended at least 10 cm
[4"] above the bottom of the tank to avoid sucking up the insoluble parti-
cles that may damage the injection assembly (Fig.2).
- Do not put the strainer on the ground.

WHAT YOU MUST NOT DO

INSTALLATION HINTS

The DOSATRON can be connected to
the main water line directly (Fig. 4) ;
on a by-pass (Fig. 5), recommended.
If your flow rate is above the opera-
ting limits of the DOSATRON, see
EXCESSIVE FLOW.
To prolong the working life of the
DOSATRON it is advisable to install
a filter (ex.: 300 mesh - 60 microns
depending on your water quality)
upstream.
This is imperative if the water
contains impurities or particles, espe-
cially if the water comes from a well.

EXCESSIVE FLOW (as an indication)
If your DOSATRON clicks more than 40 times, that is 20 cycles in 15 seconds*,
you are close to the superior flow limit. If you need more flow, you must install
a DOSATRON with a superior capacity of flow.
*DI 520 = 30 times, 15 cycles

A filter is recommended and requi-
red for the warranty to be valid.
Installing the DOSATRON on a
bypass enables clean water to be
supplied without operating the
DOSATRON and the DOSATRON to
be easily dismantled.
When connecting an
installation to the public water
supply, you must respect the
rules and regulations in force
in the country.
