9. 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.
10. REMOVAL OF THE PUMP
FROM PIPEWORK
Should it be necessary to remove the pump, follow
these instructions:
1. Switch off the power and remove the plug from
the power source.
NOTE: If the pump is wired into a
time clock or another automatic
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 and 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: When making any enquiries
about your Silensor be certain to quote
the model number from the nameplate
located on motor.
