EHEIM 1250 Mode D'emploi page 9

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 attached 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 (A). 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.
