If the UV light on your Aquascape UltraKlear UV Clarifier is not operating, check the power supply, ballast connection, and UV bulb.
Troubleshooting steps
- Confirm the UltraKlear is plugged into a working electrical outlet.
- Check the GFCI outlet and circuit breaker to make sure they have not tripped.
- Make sure the ballast is fully connected to the UV housing.
- The UltraKlear has a safety cut-off that can prevent the UV light from operating if the ballast is not properly connected.
- Disconnect power before opening the unit.
- Check that the UV bulb is securely connected to the ballast socket.
- Inspect the bulb for damage.
- Replace the UV bulb if it has reached the end of its service life.
Important
Always disconnect electrical power before opening, inspecting, or servicing the UltraKlear UV Clarifier.
If a new bulb does not operate after the connections and electrical supply have been verified, additional troubleshooting of the ballast or electrical components may be required.
