flows to the pump. Do not insert power supply plug until you have done this.
A brief noise when the pump starts up is normal. For outdoor installation. There
are several alternatives for using the hobby pump; when used out of the water it
is preferable to work through the suction nozzle with a hose. If the pump is used
in the water, it may be operated only through the incorporated prefilter. For this
purpose remove the suction nozzle and cover the suction aperture with the atta-
ched cap.
There are two optional connection variations on the pressure side: the thread-ed
adaptor for assembly of a pressure hose or an adaptor for the ascending pipe.
B/ C Both fixing strips can be transposed for universal pump assembly.
After the notch is released, the strip can be removed and, if desired,
slid into another guideway. For this purpose first remove the stops on
the upper bevelled edges of the pump body.
Servicing and maintenance
D / E Remove power supply plug. Remove suction grille (squeeze sides
lightly) and rinse coarse filter under running water.
If water is badly contaminated, clean filter more frequently. If pump is badly
contaminated on suction or pressure side, this will simply lead to noise – time
for a thorough cleaning.
Release pump cover (D) and remove pump parts as per drawing ( ). Clean
pump vigorously with set of EHEIM cleaning brushes (order no. 4009570) as
shown in fig. E: Clean pump parts under running water and reassemble in
same sequence.
