3. WIRING
a) Locate the black, blue and red wires in the unit near the pump and remove the cover
from the black and blue wires.
b) Connect: (i) Black wire to terminal L on the pcb
(ii) Blue wire to terminal N on the pcb
The plastic cover over the pcb can be removed for convenience: retain the cable tie.
c) Cut the centre loop of the red wire and strip back both ends by 5mm. Connect the
bared ends to the black de-mountable plug TB1 (non-polarized) on the pcb.
d) Fit the spare earth wire (clip fitted) to the back panel side flange.
If the plastic cover was removed, secure in its original position with the original cable
tie.
Unhook the pump assembly and fit in its final position (Fig. 3).
Connect a drain hose to the white connector when installed.
4. TESTING THE PUMP AND CONTROL
a) Connect a suitably fused supply to the unit (refer to the unit installation instructions). Allow approximately one minute
for the controls and sensor to stabilize.
b) Slowly add water to the condensate tray sump until the pump runs. Initially the pump will be noisy until the air in the
hose has been expelled. It is possible that, on this first cycle, the pump will run dry for a short period (indicated by
noise).
c) Add more water to the sump and the pump will cycle in the normal manner.
d) With the system in cooling mode, continue adding water to the sump until it reaches the higher of the sensor probes.
The cooling cycle will shut down, and the pump will continue to run until the water has dropped below the level of this
probe.
e) Replace the cabinet.
Note: Whenever the electrical supply to a unit fitted with a condensate pump and controls is interrupted, a delay of up
to 1 minute will occur before the compressor or the pump will start when the supply is reinstated.
5. TROUBLE SHOOTING
Unit will not cool No mains supply to the control board
Pump does not run Fuse on control board blown (T315mA 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 overflow circuit
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
6. 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 a syphon effect may open
the pump valves and cause noise by admitting air.
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.
