Re-assembly of the impeller:
Before the re-assembly of the impeller, clean the surface of the aluminium ring
and of the mechanical seal with alcohol or with a clean paper tissue.
The assembly is effected in reverse order.
Re-assembly of the suction casing:
First turn the 8 tapping screws (900) to the left (anti-clockwise) loosely until
reaching the cut threads start to get a grip, tighten only afterwards. Please make
sure that the screws are not tightened too strongly (tightening moment 4 Nm).
Do not use force!

If there is danger of freezing, the pump must be drained ahead of time. Also
drain all pipes subject to freezing.

In Case of Malfunction
The sealing between the motor and the pump casing is done by means of a
mechanical seal (433). It is normal that a few drops of water seep through once
in a while, especially during the break-in period. Depending on the nature of the
water and the duration of operation said mechanical seal may become leaky
after some time. If the water penetrates continuously, replace the complete
mechanical seal by a new one (433), see item 7.3.
In case of malfunction we recommend contacting an expert first.
If ball bearings must be replaced, bearings with C3 air and high-temperature
grease (min. 180°C) are to be used!
When restarting the pump, refer to item 6.
