TROUBLE SHOOTING
Pump does not run Fuse on control board blown (315 mA)
Sensor disconnected from control board
Cooling is interrupted
Restriction in pump flow allowing level to rise and trip overflow circuit
Check for blockage or kink in hoses.
Condensate at high level -- tripping overflow circuit
Filter is blocked (remove and clean)
Excessive pump noise
Air leak in hoses and/or joints
Pumping without water in sump -- control board fault
Loose connection between sensor and control board
Loose fuse, intermittent mains supply to control board.
Water syphoning due to lack of air break
APPLICATION NOTES
1
The pump will work against a 5m head. Flow rate is highest with minimum head.
2
Long lengths of drain pipe should not be exposed to the outdoor ambient, otherwise freezing of condensate may occur
during winter operation.
3
It is not advisable to have the outlet of the drain well below the position of the pump, otherwise the syphon effect may
open the pump valves.
4
For normal applications, i.e., where the drain is level or above the pump or within 3 feet below it, no extra check valves
are needed; the pump has its own internal check valves.
5
Ensure that no hose is kinked, as this could seriously affect the pump performance.
6
Clean the filter at regular intervals.
