DOSATRON 33
CHAPTER 1
INSTALLATION
RECOMMENDATIONS
1 - GENERAL REMARKS
- When connecting a DOSATRON either to the public water supply or to its
own water source, you must respect the regulations in force concerning
protection of the source i.e. backflow prevention, etc.
- In a case where the water installation is higher than the DOSATRON itself,
there is a possible risk of water and concentrate flowing back through the
DOSATRON. In this case, installing a non-return valve downstream is
recommended.
- Do not install the DOSATRON just above an acid container, (risk of acid fumes
attacking the DOSATRON) and protect it, with a lid, from possible contact with
corrosive products.
- Do not install the DOSATRON on the suction side of the supply pump (risk of
siphoning).
- The DOSATRON should be protected from frost and from sources of excessive
heat.
2 - WATER WITH HIGH PARTICLE CONTENT
- It is imperative to set up a filter (300 mesh - 60 microns) upstream of the
DOSATRON.
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).
