8 Troubleshooting
In the event of failure check the other camera housing assembly functions for
example, pan / tilt operation etc. This proves the receiver is working.
If the receiver is functioning check the correct output voltage to the pump is present
at the junction box when operated via the control system (options 230 V AC or
24 V AC).
If this voltage is present check the pump is operating and that the hose pipes are
connected correctly.
If the receiver is not functioning check the instructions provided with the receiver
unit.
Prolonged usage of the pump motor may result in failure (see section
6.2
Operation).
Do not operate the pump “dry”.
Check that the hole of the nozzle is pointing at the camera housing glass.
If the pump has had an extensive run period its thermal cutout may have operated.
Allow the pump to cool down.
