CHECKING THE DOSING SEAL
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. 18 : Between finger and thumb, pinch the component and the seal ;
push towards one side to deform the seal.
Fig. 19 : 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.
