DOSATRON

 

37

INSTALLATION HINTS

The DOSATRON can be connected to the main water line 

directly

 (

Ex. 1

) or on a

by-pass

 (

Ex. 2

), recommended.

If your flow rate is above the operating limits of the DOSATRON, see
EXCESSIVE FLOW.

EXCESSIVE FLOW 

(as an indication)

If your DOSATRON clicks more than 

36 times

, that is 

18 cycles

 in 

15 seconds

,

you are close to the superior flow limit. If you need more flow, you must install a
DOSATRON with a higher flow capacity.

Filter

Valve

To prolong the working life of the
DOSATRON it is advisable to
install a filter (300 mesh - 60
microns) upstream.
This is imperative if the water
contains impurities or particles,
especially if the water comes from
a well.
A filter is recommended and
required 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.
