PRECAUTIONS (cont...)
1 - GENERAL REMARKS (cont...)
- Before applying any aggressive
chemicals, please consult your dis-
tributor to confirm compatibility
with the dosing pump.
- All assembly should be done
without tools, hand tighten only.
2 - WATER WITH HIGH PARTICLE
CONTENT
- A (ex.: 300 mesh - 60 microns depen-
ding on your water quality) water
filter must be installed upstream from
the DOSATRON (see accessories), if a
filter is not installed abrasive substan-
ces will cause the DOSATRON to
deteriorate prematurely.
3 - WATER-HAMMER / EXCESSIVE
FLOW
- For installations subject to water
hammer a protection device such as
a check valve or union ball check
must be fitted (pressure/flow
control system).
- For automatic installations, slow
opening and closing solenoid valves
are preferable.
- In an installation where a
DOSATRON serves several sectors,
the closing of one sector and the
opening of another sector must be
done at the same time (simulta-
neous operation of the solenoid
valves).

4 - INSTALLATION LOCATION
- The location of the DOSATRON and
concentrate container should be
accessible, but should never present
a risk of pollution or contamination.
- It is recommended to label all
water lines with a warning about
the injected solution i.e. Not For
Human Consumption.
5 - MAINTENANCE
- Rinse the injection areas after using
the DOSATRON. To do this, insert suc-
tion tube into a container of clean
water and inject about 1/4 liter
[8 1/2 US Fl.oz].
- Routine maintenance once a year
will add to the life of your DOSA-
TRON. Replace the injection seals as
well as the suction hose annually to
ensure proper injection.

packaging.
- Complete maintenance and seal
kits are available.

Snap the DOSATRON into the
bracket by fitting the two lugs on
one side of the body (Fig. 1-A) into
the corresponding holes in the
bracket (Fig. 1-B), and springing the
bracket arms apart until the other 2
lugs click into place.
B
Remove the plastic caps (Fig. 1/2-C)
which block the inlet and outlet of
your DOSATRON before connecting
to the water supply.
The DOSATRON can be connected
to the water supply by means of
Ø 20 x 27 (3/4") bore flexible hose
and hose tail fittings with hose clips.
Make certain that water flows in the
same direction as the arrows on the
motor body.
