NOTICE:
A used PTFE washer should never be rein-
stalled, please replace the PTFE washer with a new one
each service.
CAUTION:
Do not over-torque the bearing unit assem-
bly.
3.2. Mounting the impeller
The impeller is to be mounted before the drive unit and
the magnet rotor are installed. Failure to do so will cause
a sudden attraction between the mounted rotor and the
impeller, causing the latter to violently hit the bearing
assembly, with likely bearing damage to occur.
CAUTION:
Before mounting the impeller, make sure
that the drive unit is NOT mounted on the vessel.
+
NOTICE:
To facilitate mounting and dismounting the
impeller, Steridose has developed an optional ’Magnet
Lowering Device’ that allows the magnet rotor to be
lowered without disassembling the complete drive unit
from the vessel. Refer to www.steridose.com or your
local Steridose representative for more information.
Carefully position the impeller onto the bearing unit
and spin by hand to ensure that the impeller runs freely.
Steridose have designed a tool for this purpose that facili-
tates mounting the impeller in hard-to-access places. See
section 3.3.
