Troubleshooting - Davey SILENSOR SLS100 Installations- Und Bedienanleitung

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.
Trouble Shooting
If the pump runs but there is no water flow or water flow is reduced, the following condition may
apply:
1. The filter requires backwashing or it is blocked. Refer to the relevant section in the Filter Manual.
2. The pump is not primed. Re-prime as per instruction in 'Starting the pump'
3. There are air leaks in the suction piping. Check all piping and eliminate leaks, also check for a loose
strainer basket lid. Air bubbles in the water flowing back to the pool would indicate a leak in the suction to
the pump allowing air to enter the pipework.
4. A leaking pump shaft seal may also prevent operating. Evidence of this would be water on the ground
under the pump.
5. The pump is not able to get water from the pool. Check that the valves to the pump are fully open and
that the pool water level is up to the skimmer box.
6. Blockage in the piping or pump. Remove the strainer basket and check for any blockage to the pump
impeller entry. Check the skimmer box for blockage.
If the pump does not operate, the following conditions may apply:
1. The power is not connected. For 240 volt only (Single Phase), check the power point by plugging in a
portable appliance to ensure power is available. Also check fuses and the main power supply switch
2. Automatic overload is tripped following an overheating period. The pump has an in-built thermal
overload which will re-set after the motor has cooled and the power supply has been re-set (turn off and
back on). Determine the cause of the overload tripping and rectify.
3. Blockage is preventing the pump from rotating.
4. Motor is burnt out - burning smell is evident. Replacement is required.
If you are unable to resolve any installation or operation difficulties with your Silensor
