Routine maintenance
Pay particular attention when handling the mixer: the check valve
protrudes from the body, therefore rest the mixer on the air inlet side
(flap area) or if it is necessary to place it on the side of the check
valve, make sure it is inside the body.
Never place the weight of the mixer on the check valve.
During the annual cleaning of the system, clean the venturi from
any dust with a vacuum cleaner. Check the operation of the flap and
the check valve (all open at nominal output, all closed at minimum
output).
