PRECAUTIONS (continued)
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.
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 the 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 tools, hand tighten only.
2 - WATER WITH HIGH PARTICLE
CONTENT
- A (ex.: 80-130 microns - 200-120
mesh 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.
