The D25 range of water powered dosing is non-electric proportional.
Dosatron D25 installed directly in the water supply line, operates by using the flow of water as the power source.
To optimize your Dosatron, we advise installing a filter (300 mesh [60 microns]) upstream, depending on your water quality.
Dosing seals should be rinsed as often as possible with clear water and changed at least once a year.
Turn off the water supply and allow the pressure to drop to zero before adjusting the injection rate.
Install necessary protections for excess flow, pressure, also water hammer (anti-hammer flow/pressure device), and install on a total by-pass line.
