TROUBLE SHOOTING
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 as described in this manual.
• Are the end caps dry? If not, allow to dry thoroughly. We recommend the use of a
hair-dryer for this.
• Possible ballast failure. The ballast in your aquarium can easily be replaced,
visit our website www.evolutionaqua.com and check the aquarium UV section
for further information.
The unit is leaking from the bulb fittings
This could be caused by an incorrectly fitted, damaged or overtightened O-ring on
the quartz sleeve. Please check the quartz sleeve O-ring, reposition it or if necessary
replace it with a new one.
IMPORTANT: Do not fit the bulb socket or end cap until the issue is solved.
If water enters the bulb socket it can cause irreparable damage to bulb socket and
ballast. Damage caused by improper fitting of the quartz sleeve, o-rings and locking
nuts are not covered under warranty.
Since fitting the evoUV my pump flow is restricted
In order to be an effective steriliser the void space inside evoUV has been narrowed
to force the water closer to the harmful UV. This is deliberate and a reduction in
pump flow is expected. For greater flow capability connect multiple evoUV devices
in parallel. Note high flow rates are not conducive to effective sterilisation results.
For optimum sterilisation through an evoUV a small, restricted flow should always
be used. This helps to ensure a long exposure to harmful UV, every time disease
pathogens pass.
Water is dripping from the hosetails
This means that the hose used is not a perfect match in terms of its internal diameter
and wall diameter. A marine safe hose clip (not supplied,) will prevent this by fitting
one on each hosetail and tightening it.
Water is dripping from the hosetail nut
This means that the nut has not been correctly tightened, or has not properly
threaded onto the male thread. Check that the rubber washer is inside the nut
(important,) then refit it and do it up. PTFE tape can be added for a greater seal
around the male thread (not supplied).
