5M CONDENSATE DRAIN
TESTING
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 outlet is level or above the pump or within 1m below it, no extra check
valves are needed; the pump has its own internal check valves.
5 Ensure that no hoses are kinked, as this could seriously affect the pump performance.
6 Regularly clean the filter.
TROUBLE SHOOTING
Unit will not cool No mains supply to the control board.
Pump does not run Fuse on control board blown (415mA x 20mm).
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 oveflow circuit.
Pump and filter 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.
