NOTA: The time required to prime the dosed solution depends on the flow
rate, the dosing setting and the length of the additive suction hose. To
accelerate the priming, set the dosing level to maximum. Once the
DOSATRON is primed, drop the pressure to zero and adjust to the required
dosing value (please refer to the paragraph on Adjusting the dosing (without
pressure), page 29.
USE
The device is designed to operate with fluids whose temperature must not
exceed 40°C [104 °F] (motive fluid, additive, motive fluid/additive mixture).
If the installation is subject to operating at temperatures lower than 5 °C [41 °
F], ensure that the installation is protected from frost (please refer to the
Precautions, page 15 section).
The dosing pumps are designed for use at pressures of up to 6 bar [85 psi].
The installation must be protected against any risk of overpressure.
The installation must also be dimensioned to avoid hydraulic oscillation (water
hammer).
If necessary, a water hammer protection device should be fitted.
