REMOVING/REFITTING THE INJECTION ASSEMBLY
WARNING: Before performing any work on the DOSATRON, you must
read to the Precautions section, page 17.
NOTA: Before dismantling, and to avoid any contact with the injected
additives, turn on the DOSATRON and allow it to draw in clear water in order
to rinse the injection assembly.
• Turn off the water supply and allow the pressure to drop to zero.
• Remove the suction hose (see Dismantling the suction hose, page 41).
• Completely unscrew the fixing nut on the injection assembly
• Pull downwards to remove the injection assembly.
• Before refitting, position the injection assembly depending on the desired
scale (percentage or ratio).
• Insert the injector sleeve into the pump body ensuring that the centring pins
on the sleeve are aligned with the groove in the pump body. If necessary, to
obtain a clearer view of the pins, unscrew the dosing adjustment sleeve to
the middle of its travel.
