- Before injecting these
substances, please consult
your distributor to confirm their
compatibility with the dosing
pump.
IMPORTANT! The personnel in
charge of installing, operating
and maintaining this equipment
must be fully acquainted with the
contents of this manual.
Ensure that the water flow and
pressure of the installation are
compliant with the Dostatron’s
specifications.
- The dosing adjustment must be
carried out with no pressure in the
system. Turn off the water supply
and allow the pressure to drop to
zero.
- The user has sole responsibility
for choosing the correct Dosatron
settings to obtain the desired dosing
rate.
- Problems with airtightness,
impurities or chemical aggression
of the seal can disrupt the dosing
operation. You are therefore advised
to check periodically that the
concentrate to be dosed is being
correctly drawn into the Dosatron.
- Change the Dosatron suction hose
as soon as it seems damaged by
the concentrate being dosed.
- Release the pressure in the system
after use (recommended).
- Rinsing of the Dosatron is
essential:
. whenever the product is changed
. before each intervention on the
Dosatron, to avoid any contact with
aggressive products.
- All assembly and tightening
operations should be carried out
using the appropriate tools, or
manually without tools (unless there
are specific recommended tightening
torques).
2-PARTICLE-LADEN WATER
- In the case of heavily particle-laden
water, a filter (e.g. 200 to 120 mesh
- 80 to 130 microns depending on
the quality of your water) MUST be
installed upstream of the Dosatron.
If this filter is not installed, abrasive
particles will cause premature wear
in the Dosatron.
3-WATER HAMMER / EXCESS
FLOW
For installations subject to water
hammer, a water-hammer arrestor
must be fitted (pressure/flow control
system).
For automated installations, it is
preferable to use slow-opening and
slow-closing solenoid valves.
If a Dosatron serves several
sectors, activate the solenoid valves
simultaneously (closure of one
sector and opening of another sector
at the same time).
