RECOMMENDATIONS
1 - When using soluble products to be
made up into solutions, we recommend
the periodic dismantling of the entire
dosing part (see : § CHANGING SEALS
IN THE INJECTION ASSEMBLy).
thoroughly rinsing all the elements
of the dosing part with water and
re-assembling them after having previously
lubricated the seal (Fig. 10) with a silicone
lubricant, in the case of difficulty in re-fitting.
2 - an air inlet, an impurity or a seal's failure can
interrupt the dosing function ; periodically check
out that the concentrate is correctly drawn up, thus
incorporated into the water.
3 - Before putting the Dosatron into operation after
a non-use period, remove the motor piston and soak
it into lukewarm water < 40° C [104° F] overnight. this
helps to dissolve any deposits which may have dried
onto the piston motor.
HOW TO DRAIN THE DOSATRON (in case of freezing temperature)
- turn off the water supply and let
the pressure drop to zero.
- screw the bypass button into the
median position.
- Remove the injection assembly.
- Disconnect the water inlet and
outlet fittings.
- also unscrew the bleed screw (Fig.
11-P), remove it and let the water
flow out.
