• Do not install the DOSATRON on the water pump suction circuit (risk of
siphoning).
• The user is responsible for replacing the injection seals once a year to
ensure accurate dosing.
• The adjustment of the Dosatron’s dosing is the sole responsibility of the user.
The user must strictly adhere to the recommendations of the chemical
manufacturer.
• Ensure that the water flow and pressure of the installation are compliant with
the DOSATRON specifications.
• The dosing should be adjusted with no pressure in the system. Turn off the
water supply and allow the pressure to drop to zero.
• The user shall be solely responsible for correctly adjusting the DOSATRON
to achieve the desired dosing rate.
• Problems with airtightness, impurities or chemical aggression of the seal can
disrupt the dosing operation. We therefore recommend that you periodically
check that the concentrate to be dosed is being correctly drawn into the
DOSOTRON.
• Change the DOSATRON suction hose as soon as it appears to be damaged
by the concentrate being dosed.
• Release the pressure in the system after use (recommended).
• The DOSOTRON must be rinsed:
−whenever the concentrate is changed
−before handling the DOSATRON, to avoid any contact with aggressive
concentrates.
• All assembly and tightening operations must be done by hand and without
the use of tools (except for those with recommended tightening torques).
2. Water with a high particle content
If the water has a high abrasive particle content which could cause premature
wear of the Dosatron, it is essential to install an upstream filter (e.g 60 microns
- 300 mesh or finer).
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.
• If a DOSATRON is used to supply several sectors, activate the solenoid
valves simultaneously (close one sector and open another sector at the
same time).
