CHANGING THE EXTERNAL INJECTION SEALS
(D3WL3000IE)
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 !
In the event of using with hard water it is recommended
that you descale the external injection section at a
frequency to be validated on site.
Remove the nuts identified on the view below.
Replace the O-ring seals, the non-return valve, the
membrane and the whole seat of the umbrella valves
(do not replace the umbrellas alone). Reassemble all
the elements in the opposite direction from disassembly
taking care to respect the direction of assembly of the
membrane and the valve seat (see perspective view)
