PRECAUTIONS (cont...)
1 - GENERAL REMARKS (cont...) -
Rinsing of the Dosatron is required:
. when changing chemicals,
. before handling the Dosatron, to
avoidany contact with the chemical.
- Before applying any aggressive
chemicals, please consult your
distributor to confirm compatibility
with the dosing pump.
- 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. 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 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.
