and wait until a stable flow, free of air-bubbles, is obtained, then retighten the bleeding screw
( see the enclosed Dosing Booster Manual ).
6) Check the dosing booster's impeller chamber for clogging:
If it is clogged - it should be dismantled and thoroughly cleaned (see the enclosed Dosing Booster Manual).
If after implementing all the above steps the malfunction is still not fixed - consult your Netafim ™ representative.
