Starting The Pump; Pump Operation; Emptying The Strainer Basket - Davey Silensor Installations- Und Betriebsanweisungen

Starting the Pump

To operate efficiently and prevent pump damage there must be a free flow of water to and
from the pump. Before starting ensure that:
- all pipework is correctly sealed.
- the pool/spa water level is at the correct height.
- that all appropriate valves are open and there is nothing preventing the flow of water
through the system.
1. First prime the pump by removing the strainer basket lid and filling the strainer basket
area with water. Replace the lid, ensuring that it seals on the large oring.
2. Connect to the power supply and switch on.
3. Allow the pump to run, so that any air trapped may be expelled.
4. If prime is not established within approximately two minutes, as evidenced by a strong flow
of water, switch off the pump and repeat the procedure. Continued evidence of air under
the strainer basket lid indicates an air leak in the suction piping which should be rectified
to avoid pump damage.

Pump Operation

For optimum pump performance, the strainer basket housing should always be full of water
and free from air bubbles. The water level of the pool should always be maintained to at least
halfway up the skimmer box ensuring water is in the pump at all times. From time to time it
may be necessary to re-prime the pump. This should be carried out as described above.
Never run pump dry. Running the pump with no water may damage the
mechanical seals, causing leakage and flooding. Dry running damage and
associated damage is not covered under warranty. Silensor incorporates
dry run protection which will need to be re-set by turning off the power
supply, reducing potential damage.
Emptying the Strainer Basket
The strainer basket should be inspected frequently through the transparent lid and emptied
when a build up of rubbish is evident. The directions below should be followed.
1. Switch off pump.
2. Close all valves in pipework.
3. Unscrew the strainer basket lid anti-clockwise and remove.
4. Remove the strainer basket by lifting upwards from its housing.
5. Empty the trapped refuse from the basket. Hose out with water if necessary.
6. Check the strainer basket for cracks, replace the strainer basket in the pump if OK.
7. Replace the lid and ensure that it seals on the large rubber oring. Firm hand tightness
only is required. The oring & thread can be lubricated with Hydra slip or equivalent
products.
8. Open all valves in pipework.
Failure to undertake regular maintenance may cause damage not covered
by warranty.
