Trouble Shooting; Removal Of The Silensorpro From Pipework; Water Quality - Davey SilensorPRO SP200BT Instructions D'installation Et D'utilisation

11. TROUBLE SHOOTING

If the pump runs but there is no water flow, or water flow is reduced, the following conditions may apply:
• The filter requires backwashing or it is blocked. Refer to the relevant section in the Filter Manual;
• The pump is not primed. Re-prime as per instruction in 'Starting the pump';
• 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.
• A leaking pump shaft seal may also prevent operation. Evidence of this would be water on the ground
under the pump.
• 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. Typically, half way up the face of the skimmer box is
sufficient;
• 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:
• The power is not connected. For 220-240 volt only, check the power point by plugging in a portable
appliance to ensure power is available. Also check fuses and the main power supply switch;
• Automatic overload is tripped. The pump has an in-built thermal overload which will reset automatically
after the motor has cooled following an overheating period. Determine the cause of the overload tripping
and rectify. Reset the pump by switching the power OFF for 30 seconds;
• Blockage is preventing the pump from rotating.

12. REMOVAL OF THE SILENSORPRO FROM PIPEWORK

Should it be necessary to remove the SilensorPRO, follow these instructions:
• Switch off the power and remove the plug from the power source;
• Unscrew the barrel union on the front and top of the pump, releasing the pump from the pipework;
• Slide the pump out of position.
