Maintenance

RECOMMENDATIONS

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

HOW TO DRAIN THE DOSATRON

(in case of freezing temperature)
- Turn off the water supply and let the pressure drop to zero.
- Remove the injection assembly, see § CHANGING THE MOTOR PISTON.
- Remove the bell and the motor piston.
- Disconnect the water inlet and outlet fittings.
- Remove the lower pump body from the mounting bracket and empty any
remaining water.
- The DOSATRON can now be reassembled, having first cleaned the seal.
