PRECAUTIONS (cont...)
1 - GENERAL REMARKS(cont...)
Follow the instructions in this
manual and take additional safety
measures appropriate to the liquid
being pumped and the temperature
of the water that powers the
DOSATRON.
Be extremely careful in the presence
of hazardous substances (e.g.
corrosives, toxins, solvents, acids,
caustic, flammables, etc.).
- Before applying any aggressive
chemicals, please consult your
distributor to confirm compatibility
with the dosing pump.
- When installing the DOSATRON on
a hot water system (60°C/140°F
max.), a dosing unit with
"T"-option is required. High
temperature increases the risk
and the dangerousness of the
substances mentioned above. It is
strongly recommended to identify
and label the dosing unit and the
complete hot water installation
as such, and to respect the
corresponding regulations in force.
IMPORTANT !
It is the responsibility of the
owner/operator to check that
the flow and pressure of the
installation do not exceed the
DOSATRON characteristics.
- Adjustmentmust be made when
there is no pressure in the Dosatron.

-Turn off the water supply and allow
the pressure to drop to zero.
- It is the responsibility of the
owner/operator of the DOSATRON,
to determine the correct amount of
solution and injection ratio to obtain
the desired result.
- An air inlet, an impurity or
a chemical attack on seal can
interrupt the dosing function. It is
recommended to periodically check
that the solution is being correctly
drawn up into the DOSATRON.
- Change the suction tube as soon as
it seems damaged by the chemical.
- Relieve the pressure after use
(advised).
- Rinsing of the DOSATRON is
required :
. when changing chemicals,
. before handling the DOSATRON, to
avoidany contact with the chemical.
- All assembly should be done
without tools, hand tighten only.
2 - WATER WITH HIGH PARTICLE
CONTENT
- A (ex.: 50 mesh - 300 microns
depending on your water quality)
water filter must be installed
upstream from the DOSATRON
(see accessories), if a filter is not
installed abrasive substances 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 (simultaneous
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.
IMPORTANT ! Not For Human
Consumption.
5 - MAINTENANCE
- Rinse the injection areas after using
the DOSATRON. To do this, insert
suction 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
DOSATRON. Replace the injection

seals as well as the suction hose
annually to ensure proper injection.
6 - SERVICE
- This DOSATRON was tested prior
to packaging.
- Complete maintenance and seal
kits are available.
- Call your DOSATRON distributor
for service or parts.
