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 previously lubricated the seal
(Fig. 5)
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
< 104° F [40° C] 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.
- Open the D132GL unit
(Fig. 6)
.
- 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.
- Close the D132GL unit
(Fig. 7).

FITTING THE SUCTION TUBE
If the DOSATRON has already been used, please imperatively refer to §
PRECAUTIONS.
- Unscrew the nut
(Fig. 8)
at the bottom of the injection assembly and put it
onto the tube.
- Push the tube onto the barbed fitting as far as it will go and screw on the
nut by hand
(Fig. 9)
.
CLEANING THE MOTOR PISTON (with pressure off)
- Turn off the water supply and allow
the pressure to drop to zero.
- Open the D132GL unit
(Fig. 6).
- Unscrew and remove bell-housing by
hand
(Fig. 13)
.
- Remove the motor piston
(Fig. 14)
by
pulling it up.
- Rod and plunger piston are fixed
to the motor piston and taken out
simultaneously.
- Change and reassemble in the
reverse order to the above.
- Refit the bell-housing (take care not to
damage its seal) and tighten
by hand.
- Close the D132GL unit
(Fig. 7).
