PRECAUTIONS (cont...)
(solvents, acids, and corrosive,
toxic, caustic and inflammable
substances, etc.).
- For dosing of these
substances, consult with your
distributor before use in order
to confirm they are compatible
with your dosing pump.
A dosing pump with the option
'T' is required when installing
the DOSATRON on a hot-water
supply (60°C/140°F Max).
The higher temperature
increases the risk and danger of
the aforementioned substances.
It is strongly recommended
that you place signs on the
dosing pump and the hot-water
installation warning of this
risk and that you comply with
legislation in force.
WARNING! Personnel in
charge of installing, using and
maintaining this equipment
must read this manual.
- 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 avoid any contact with the
chemical.
- all assembly should be done
without tool, hand tighten only.
2- WATER WITH HIGH PARTICLE
CONTENT
- a (ex.: 300 mesh - 60 microns
depending on your water quality)
water filter must be installed
prior to 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
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. Not For
Human Consumption.
5- MAINTENANCE
- Rinse the injection areas after
using the DOSatRON. to do this,
insert suction tube into container
of clean water (~ 1 liter [0.264.US
GaLLONS]).
.
- Routine maintenance once a
year will add to the life of your
/ DOSatRON. Replace the dosing
seals as well as the suction tube
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.
