RECOMMENDATIONS
1 - When using soluble products
to be made up into solutions, we
recommend the periodic dismant-
ling of the entire dosing part
(see : § CLEANING
AND REFITTING THE
SUCTION VALVE
§ CHANGING SEALS
IN THE INJECTION
ASSEMBLY).
Thoroughly rinsing all the ele-
ments of the dosing part with
water and re-assembling them
after having previously lubri-
cated the seal (Fig. 7) with a
silicone lubricant, in the case of
difficulty in re-fitting.
2 - 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.

- Disconnect the water inlet and out-
let fittings.

sembled, having first cleaned the
