- Rinsing of the DOSATRON is
essential:
. whenever the product is changed
. before handling the DOSATRON,
to avoid any contact with
aggressive products.
- All assembly and tightening should
be done manually without tools.
2-WATER WITH HIGH PARTICLE
CONTENT
A filter sieve must be installed
upstream of the DOSATRON when
water has a high particle content
(e.g. 300 mesh - 60 microns
depending on your water quality) If
this filter is not installed, abrasive
particles will cause the DOSATRON
to wear prematurely.
3 - WATER-HAMMER/OVERFLOW
- For installations subject to water
hammer, a water hammer protection
device must be fitted (pressure/flow
control system).
- For automated installations, it is
preferable to use slow opening and
slow closing solenoid valves.
- In the case where a DOSATRON
serves several sectors, activate
the solenoid valves simultaneously
(closure of one sector and opening
of another sector at the same time).
4 - INSTALLATION LOCATION
- The DOSATRON and the product
to be dosed should be accessible.
- Their installation must under no
circumstances present a pollution or
contamination risk.
- It is recommended that all water
pipes are marked showing that the
water contains additives and with
the wording: "IMPORTANT! Non-
potable water".
5-MAINTENANCE
- After use, the aspiration of clear
water is recommended.
- Annual maintenance will optimise
the life of your DOSATRON.
Annually replace the dosing part
seals and the product suction hose.
