7.6 NOZZLE CHECK
Daily the nozzles must be checked and the clogged ones must be cleaned and
those damaged replaced. Remove the nozzle hole fillings using just a brush of nylon
or an
pressured air jet . Change them if the nozzles are not regular and if the flow rate is
higher of 10% compared to values reported in the tables of the manufacturer.
To clean the nozzles:
-Remove them using suitable keys.
-clean them using a jet of water from air impurities
accumulated inside.
-Clean the hole of the plate, taking care not to
damage it.
-check if the O-rings are in perfect condition and
replace them if necessary, to avoid inefficiency of
the machine due to loss of circuit loading.
-Insert the diffuser.
Be careful not to damage the threads on the nozzles!
