Troubleshooting - Davey Silensor Installations- Und Betriebsanweisungen

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, contact
the supplier from whom the pump was purchased or your nearest Authorised Davey Pool
Equipment Service Centre. If any further assistance is required, contact the Davey Customer
Service Centre at the address indicated in this manual.

1. Switch off the power and remove the plug from the power source.
NOTE:
control, the wiring should be removed by a qualified electrician.
2. Close the water valves on the pool return and the pump inlet pipework.
3. Remove the discharge & suction barrel unions taking care not to lose the orings.
4. Move the pipework with the barrel unions attached until the pump can be pulled clear.
NOTE:
the model number from the nameplate located on motor.
Water Quality
Maintaining balanced water chemistry is important to the life of your pool pump. This pump is
designed to be used with Pool & Spa water, balanced in accordance with Langlier Saturation
Index, with a pH level of between 7.2 and 7.8 and is regularly treated with a chlorine sanitising
agent with the level not exceeding 3ppm. Salt levels should be maintained between 4000ppm
- 6000ppm.
Please consult your local pool shop regularly to have your water tested.
If the pump is wired into a time clock or another automatic
