dosatron SD25AL5 Manuel D'utilisation page 44

- Adjustment of the system dosing is the exclusive
responsibility of its user. The user must rigorously
comply with the recommendations of the
manufacturer of chemical/pharmaceutical products
and dietary supplements.
Warning
During the installation, use and maintenance
of the DOSATRON SD25AL5 system, comply
with the safety instructions; use adequate tools,
protective clothing and safety goggles when
you are working on the equipment and install it
with a view to ensuring hazard-free operation.
The installation, connections of the various
subassemblies and maintenance of the SD25AL5
system must be carried out with the power off,
the water supply circuit closed and the pressure
released.
N.B. All the electric connections and the
cabling must comply with local construction
standards.
Follow the instructions in this manual and take
safety measures appropriate to the nature of the
liquid additives and the water temperature.
Be extremely cautious in the presence of
dangerous substances (corrosive, toxic, dissolving,
acids, caustic substances, inflammable substances
or substances with a high risk of gaseous release,
etc.).
- For the dosing of these substances, please
consult your vendor before any use to confirm
the compatibility with the doser. An increase in
temperature increases the risk and aggressiveness
of the substances listed above.
The personnel in charge of the installation,
use and maintenance of this equipment must
have perfect knowledge of the content of this
manual.
- Ensure that the flowrate, water pressure and
the electricity supply grid are compliant with the
characteristics of the SD25AL5 system.
- The dosing must be adjusted without pressure.
Close the water inlet and reduce the pressure to
zero.
- The user alone shall be responsible for the
correct choice of the system settings to obtain the
desired dosing.
- An air intake, an impurity or a chemical attack of
the seals may interrupt the correct operation of the
dosing.
- Change the suction pipe or the level detection
of the SD25AL5 system as soon as they appear
deteriorated by the product dosed.
- At the end of use, remove pressure in the system.
- It is necessary to rinse the system by sucking
clean water in the following cases:
1- at every change of product and after every use
in the case of hazardous products (residues)
2- before every handling operation in order to
prevent any contact with aggressive products.
- Any assembly on and any tightening of the doser
subassemblies must be done manually, without
tools.
Waters with impurities
- A meshed filter must be fitted upstream of the
system (e.g.: 300 mesh - 60 microns) in order to
improve the quality of the water while protecting
your facility from the mineral or organic particles
which encourage equipment wear (water meter/
pump/water supply points) and the development
of biofilms. Should filtration not be sufficient to
eliminate certain minerals, a pre-treatment will be
necessary to protect any upstream installation (iron
removal, softening, etc.)
Water hammer/excessive fl owrate
- For operations subject to water hammer, it is
necessary to install an anti-water hammer device
(pressure/flowrate regulation system).
- For automated systems, it is preferable to use
slow-opening and closing solenoid valves.
Location of the installation
- The DOSATRON and the product to be dosed
must be accessible. Their installation must
under no circumstances present a pollution or
contamination risk.
- Try to position the water bypass pipework
supplying the Smart Dosing device in such a
way that the Smart Dosing device is sufficiently
high enough to facilitate reading the screen and
the menus (possibility of using flexible water
connections of the stainless braid type).
- It is recommended that all the water pipework
be stamped indicating that the water contains
additives and the instruction: "WARNING! Not
drinking water".
- The device is intended to be installed inside a
technical room or building.
