7. Maintenance and care
To significantly extend the service life of your pump, and to ensure trouble-free function,
we recommend regular maintenance and cleaning. With a few hand movements every
user can easily execute all maintenance tasks. For this, the pump must be dismounted, as
described in chapter 8. All parts can be cleaned with a non-metallic brush and a neutral
cleaner. Ensure that the cleaning agent does not get into the pond water. Carefully rinse
off all cleaned parts with clean tap water, before putting the pump back together and
placing it in service. If the pump is heavily calcified, you can place the run unit and the
motor block in a descaling solution for stainless steel parts. In this regard comply with the
use instructions provided with the descaling agent.
7.1.
Maintenance intervals
The time intervals for the necessary maintenance (complete cleaning) depend strongly on
the pond water pollution. Select the time intervals accordingly for cleaning.
If you during maintenance defects or wear ascertained, replace the corresponding parts
(See ordering spare parts).
7.2.
Winter - maintenance
• Protect your pump from freezing!
• If there is danger of freezing, take the pump out of your garden pond.
• Completely clean the pump as specified in the instructions.
• Store the pump over winter in a frost-free location.
8. Dismounting / mounting the pump
1.
Comply with the safety measures. Disconnect the pump from the mains supply!
2.
Remove the top shell from the pump cage in accordance with fig. I
3.
Loosen the pump's retaining bracket as shown in fig. I/2.
4.
Remove the sponge filter that is inserted (if installed).
5.
Remove the flow rate regulator and the inflow mesh (WPF 1500 S) by unscrewing
from the pump inflow cover.
6.
Turn the inflow cover (6) anticlockwise approx. 20° (Fig. III/2).
7.
Pull the inflow cover (6) out of the pump.
8.
Pull the rotor with rotor axle and bearing (4, 3 and 2) out of the pump (III/4).
Note: For technical reasons, the impeller and the magnet can be turned against each
other by a certain angle.
9.
Mount the pump as follows:
9.1. Insert the rear bearing (4) and the rotor axle (2). Make sure that they are
perfectly seated in the bearing. Then insert the rotor (3) into the pump and
attach the front bearing to the rotor axle.
9.2. Insert the inflow cover (6) and turn clockwise to the stop.
10. Re-insert the pump into the pump cage by following the steps in reverse order.
For trouble-free operation, repeat this procedure depending on the degree of fouling and
duration of operation.
