Testing
Fill the drain pan with clean tap water until the water level is approximately half way up
the KAROO body (Fig. 3. Pump On).
The KAROO should start to pump. It may be noisy initially until any air has been
purged from the system.
Continue to fill the drain pan until the water level reaches the Alarm On level (Fig. 3.).
The alarm contacts should open.
Allow the KAROO to empty the drain pan. The pump should stop and the alarm relay
reset when the water level gets close to the bottom of the KAROO body (Fig. 3. Pump
Off).
Trouble Shooting
Pump does not run:
Check fuse and electrical supply
connections.
Check water level is high enough to start
the pump.
Pump is noisy:
Check that the KAROO mains cable and
outlet tube are not vibrating against the
sides of the drain pan and that there is no
debris in the bottom of the drain pan.
Pump continues to run with no water:
The water sensor can become over
sensitive if contaminated by dirt or certain
cleaning chemicals. If this occurs,
disconnect the KAROO from the mains
supply and flush the sensor housing with
clean tap water for around 30 seconds (Fig.
4.). If the problem persists, flush with
methylated spirit and then rinse with water.
