C.3.4 Generator installation above waterline
The Panda is equipped with a direct drive water intake pump mounted directly on the motor.
Since the intake pump is an impeller pump there are wearing parts which are likely to require
replacement after a period of time. Ensure that the genset is installed so that the intake pump can
be easily accessed. If this is not possible, an external intake pump could be installed in an easily
accessible location.
If the generator is installed above the waterline, it is possible that the impeller will wear out faster,
because after starting, the pump runs dry for some seconds.
The raw water hose should form a loop as near as possible to the raw water inlet of the generator
(see picture below). This ensures the pump only sucks in air for a short time. The impeller pump
will be lubricated by raw water and the impeller life span will be increased.
By the installation of a check valve in the raw water inlet line, which is under the waterline, this
problem can be restricted.
The impeller pump will remain intact longer, if an electrical booster pump is installed, and is stron-
gly recommended in order to preserve the impeller pump.
NOTE:
Never change the impeller for many years, without exchanging the old pump. If the
sealing ring is defective within the pump, raw water runs into the sound cover of the
genset. A repair is then very expensive.
Replacement impeller and also a spare pump should always be on board. The old
pump can be sent back to Fischer Panda.

3. Thru hull
Make certain that the raw water filter lies
above the water level, otherwise with cle-
aning water can penetrate by the thru hull.
An external pre-pump can relieve the
impeller.
