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.
