6.3 MAINTENANCE
Check of the mechanical seal
During the check of the mechanical seal, you must make sure that no abnormal infiltrations
occurred in both the seals. You must also check that no other liquids have entered the
stator and the oil tank. If the aerator or the seal is new, you are advised to have everything
overhauled after a week of work.
In case of normal functioning, examine the aerator at least once a year. If the aerator
operates in intensive conditions, make sure it is overhauled more frequently.
Oil inspection
General revision
Considering the presence of spherical bearings, the aerator needs a general revision every
three years. Take voltage from the aerator and disconnect the electric cable from the
closest cutout box or the control panel.
Routine maintenance and repairs must be carried out by specialized
technicians in possession of adequate qualifications and equipped with
the right tools. These technicians must have become fully familiar with
the contents of this manual and with any other documentation supplied
with the product.
After having dismantled the aerator for the repair, please apply to the
fastening moments of the bolts on page 27 for a correct assembling.
Extraordinary maintenance must only be carried out by authorized
workshops.
Put the aerator on its supports and remove the fill-drain screw with a
suitable key, putting the oil in a container. If only oil comes out, this
means that the seal is intact. Make also sure that the oil quantity has not
considerably decreased, then pour the oil into the tank again.
If the oil appears lightly grey-yellowish and viscous or there is a water
presence, it means that the seal bearing or the seal are damaged and they
have to be replaced. In this case the aerator must be taken to a workshop
for a general revision. Fill in the tank with AGIP ITE 360 oil (from 0,6lt
to 4lt according to type). Tighten the blowdown and the filling screws.
Replace the grommets under the screws.
These operations must be carried out by authorized workshops or
at S.C.M. Tecnologie.
