Maintenance

RECOMMENDATIONS

1 - When using soluble products put into stock solutions, contact
manufacturers/distributors to verify the real solubility level of oral powders.
It is preferable to use a Dosatron with a high dosing rate (min. 4 - 5%) to
guarantee a sufficient pre-dilution rate for powders. After use, always rinse
the dosing pump by injecting clear water. Open the rinsing/ fast priming
valve situated downstream of the Dosatron for a high-flow energetic rinsing/
cleaning. We recommend periodic dismantling and rinsing of the suction
valve found in the bottom of the dosing part to prevent possible leaks and
backflow into the tank due to clogging in the valve (Fig. 14).
2 - Please read the § PRECAUTIONS before performing any maintenance
on the DOSATRON. Before putting the DOSATRON into operation after a
long non-use period, remove the motor piston and soak it in lukewarm water
at < 40°C (104° F) for a few hours. This helps to remove any deposits which
may have dried onto the motor piston.

DISMANTLING THE SUCTION HOSE
Before performing any maintenance on the DOSATRON, please make sure
you refer to the § PRECAUTIONS.
Before dismantling, and to avoid any contact with the products dosed,
operate the DOSATRON by aspirating clear water to rinse the dosing pump,
the hose and the dosing part.
- Unscrew the nut at the bottom of the dosing part (Fig. 15)
- Pull downwards to remove the hose from the suction valve head (Fig. 16).
- Reassemble in the reverse order. If needed, please read the
§ CONNECTING THE SUCTION HOSE.
IMPORTANT: connecting the hose incorrectly or a hose damaged by the
additives dosed may cause an air tightness problem with the suction which
may lead to unpriming or under-dosing
