Installation Hints - dosatron D 25 F Manual De Utilización

ASSEMBLING THE DOSATRON (cont...)
the DOSatRON is delivered with a suction tube (cut it to the needed length)
enabling its use with a large capacity concentrate container.
the tube must be fitted with its strainer and weights.
the instructions for fitting the tube are to be found in the specific chapter.
NOtE : the maximum suction height is 4 meters (13 vertical feet).
Fit the tube, equipped with its strainer and its weight, and immerse it in the
solution to be injected.
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 par-
ticles that may damage the injection assembly (Fig.2).
- Do not put the strainer on the ground.

WHAT YOU MUST NOT DO
Under no circumstance should the solution level be above the water
inlet of the DOSATRON (to avoid siphoning situations).

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 depen-
ding on your water quality) upstream.
this is imperative if the water contains
impurities or particles, especially 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 maximum flow limit. If you need more flow, you must
install a DOSatRON with a higher capacity of flow.
*D 25 RE 10 = 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 res-
pect the rules and regulations
in force in the country.
