dosatron D 8 RE 3000 Manuel D'utilisation page 34

PRECAUTIONS (cont...)
- Before applying any aggressive
chemicals, please consult
your distributor to confirm
compatibility with the dosing
pump.
- When installing the DOSATRON
on a hot water system
(60°-C/140°-F max.), a dosing unit
with "T"-option is required. High
temperature increases the risk
and the dangerousness of the
substances mentioned above. It is
strongly recommended to identify
and label the dosing unit and the
complete hot water installation
as such, and to respect the
corresponding regulations in
force.
WARNING!
The personnel being responsible
for installation, use and
maintenance of this material must
be perfectly familiar with the
contents of 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.
- Adjustment must 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 tools, hand tighten only.
2- WATER WITH HIGH PARTICLE
- A (ex.: 60 microns - 300 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
- 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).
