Routine maintenance
Pay particular attention to the handling of the mixer: the clapper
sticks out from the body, thus placing the mixer from the air intake
(flap area) or if you need place it on the side of the clapper, pay
attention that it is within the body. Never put the weight of the mixer
on the clapper. During the annual cleaning of the system, clean the
venturi from any dust using a vacuum cleaner. Check operation of
the flap and the clapet (all open to the max flow rate, all closed to
the minimum flow rate).
