FAULT FINDING
The pump control panel is fitted with indicator lights to show whether the pump is running or tripped.
If a tripped light is illuminated, this means that an overload has occurred and the pump has been
isolated. A qualified engineer should be called to check any faults.
(“Water in the chamber will not go down”)
1. There is insufficient water to fully tilt the START float switch. Add more water.
2. Inflow to the chamber is too great for the pump to cope with. Check the cause of the
excessive inflow and rectify.
3. The pump is blocked. Switch the mains supply off, lift the pump from the chamber and
remove the blockage.
4.
Outlet pipe is blocked. Call an engineer.
5. Electrical supply has failed. Check mains supply and setting of control panel switches.
(“Water goes down but pump keeps running”)
1. The STOP level float switch is set too low. Check the setting level and adjust if necessary.
2. The pump selector switch is set to MANUAL. Set switch to AUTO (for control panels with
AUTO – OFF – MANUAL switches only)
ROUTINE MAINTENANCE
No routine maintenance is necessary on the pump itself, as the motor bearings are generally
permanently lubricated. It is however recommended that the pump(s) are checked every six to twelve
months to ensure that the oil chamber is free from contamination (as per the manufacturer’s
instructions), and to check the pump(s) for any blockages and to clean away any build up of fat/dirt.
1. Lift manhole cover and secure the site for Health & Safety reasons.
2. Check the pumps are operational by switching each pump to manual from AUTO.
3. Check the start level float switch is operational by lifting the float switch on each pump.
4.
Check they are not contaminated with grease or other debris.
5. Check pumps are secure visually.
6. Ensure high-level alarm is operational by lifting the float switch.
7. Remove any large objects which may have found their way into the chamber.
8. Check panel is secure.
9.
Ensure the pump(s) control panel is switched on and both switches are restarted on auto.
10. Close manhole and electrical cabinet.
WIRING DIAGRAM(S)
The wiring diagram(s) for the control panel or alarm unit (if applicable) are usually contained within the
panel or alarm unit for the convenience of your installer. A copy of this wiring diagram should be placed
with this manual for future reference.
PUMP HANDBOOK
Each pump is supplied with its own handbook, which will normally be found within the pump
packaging. A copy of this handbook should be placed with this manual for future reference.
