Position of the support feet
Regulating nut
Installation in tank
If installing in an empty tank, clean any debris or
coarse solid matter out of the sump before putting the
pump unit into operation.
The extension pipe is provided with a holed plate for
retrieving and raising the unit and with three fixing
points at 120° to allow anchoring to the walls by stain-
less steel ropes if necessary (e.g. if the plane on which
the unit rests is uneven or the unit has to deal with
filamentary and coarse solids).
Use a support grip unit and cable holders for suspend-
ing the power cables.
For the suspension of cables we recommend using a
support grip unit, which must be attached to the hole
on top of the suction pipe.
Cables should be kept taut to prevent any possibility of
their being sucked in by the machine.
The horizontal portion of the cable may be tied to the
stainless steel rope mentioned above.
Make sure that cables are not bent or squeezed in
such a way as to be liable to break or wear out.
Installation in full tank
The Jet aerator unit can be installed in a full tank: the
positions of the support feet have been designed to
enable the unit to sit naturally after a short period of
operation.
Sharpened support feet
The sharpened support feet provided sink 1-2 cm into
the tank bottom, ensuring stability of the unit even in
the event of repeated start-ups or persistent vibration
conditions.
If the tank bottom slopes or is very uneven, the bearing
tips need adjusting to provide better seating.
If the tank bottom is even, the lower adjusting nut can
be eliminated.
IMPORTANT! Use the torques required (see “Recom-
mended torque for screws”) to tighten the nut and upper
locknut.
For lined tank or tank made of steel, vibration damping
supports have to be used.
Levelling must be carried out in the same way as indi-
cated for standard sharpened support feet.
