CHANGING SEALS IN THE INJECTION ASSEMBLY (with pressure off)
Frequency : Once per year.
IMPORTANT ! Use no tool or metallic utensils
ADVICE: Before dismantling any part of the injection assembly it is
advisable to operate the DOSATRON, injecting clean water so as to rinse
through the injection system. In this way, risks of contact with concentrated
solutions in the injection assembly are minimized.
During any such intervention, wear protective eyewear and gloves !
METHOD OF REMOVING SEAL
Fig. 15 : Between finger and thumb, pinch the component and the seal ;
push towards one side to deform the seal.
Fig. 16 : Increase the deformation to grip the part of the seal thus exposed
and pull it out of its groove.
Clean the seal seating without any tools.
Refitting is done by hand.
It is very important that the seal is not twisted once in place as this would
impair its efficiency.

METHOD FOR REPLACING THE PLUNGER PISTON
Use an open-ended 8 spanner to unscrew the worn plunger piston from the
plunger catch.
Put the new plunger piston in place (seal factory pre-assembled) screwing it
in with the same spanner.
It is very important that the seal is not twisted once in place since this may
