TROUBLE SHOOTING
My pond water is not clear, is this due to the evoUV not working correctly?
Koi, goldfish and other pond inhabitants can cause murky water by stirring up the
bottom of the pond. This murky water should not be confused with suspended algae.
Always check all your pond filtration is working and is being maintained correctly
prior to checking the evoUV.
If the UV bulb is not lit, then you need to investigate the power to your unit.
• Has your RCD tripped? If yes, check your wiring and reset.
• Examine the UV bulb for signs of failure, and replace if necessary.
• Is the UV bulb fitted correctly? Unscrew the end caps and ensure correct fitting as
per the instructions on page 14.
• Are the end caps dry? If not, allow to dry thoroughly. We recommend the use of a
hair-dryer for this.
If only one bulb is lit up on the evo110 only.
• Please check the UV bulb as per UV bulb maintenance on page 14.
• If one bulb is still not lit, swap the bulb end connectors at one end of the evo110.
The unit worked well when I first installed it but recently my pond has gradually
gone green again – what is wrong?
Quartz sleeve may have become dirty and requires cleaning (see page 15). Also
make sure you have the right model for your pond size. Ensure your pond filtration is
removing fish waste and debris efficiently. Dirt in ponds will affect the efficiency of
the evoUV. Check that your pond water volume is pumping through the evoUV every
2 to 3 hours.
Only after you have carried out these checks should you contact your Evolution Aqua
dealer, who will then be able to advise you further.
