Pressing the impeller back on the shaft with BADU Hydrostar 20, 25, 32 :
First screw impeller cap (260) with O-ring (412.6) into the impeller hub, then,
with uniform pressure onto the impeller cap, press the impeller onto the shaft
until it hits the limit stop. For the absorption of the counterforce, support the end
of the motor shaft (centre of the fan hoof). Otherwise the force exerted may
stress the ball bearing.
Re-assembly of the motor unit into the pump casing :
Tighten the 8 allen screws (914.1) with approx. 5 Nm tightening torque.
Do not use force !
7.6
In areas subject to freezing the pump and all pipes must be emptied prior to
freezing taking place. If the pump is equipped with a drain plug (903), remove
the plug and let the water drain from the pump and pipes.
8.
Malfunction
The sealing between the motor and the pump housing is done by means of a
mechanical seal (433). If once in a while a few drops of water seep through this
is not a cause for concern especially during the break-in period. Depending on
the nature of the water and the duration of operation said mechanical seal may
start to leak after some time. Whenever water is leaking constantly, a new and
complete mechanical seal (433, 475, 412.3) should be installed.
In case of malfunction it is recommended that the builder of the pool unit
be contacted first.
