UVC bulbs & quartz sleeve maintenance
The UVC bulb must be replaced yearly – it is recommended that the bulb is replaced in
the spring or early summer, in order to provide the maximum performance during the most
problematic period of the year for green water.
The quartz sleeve can become coated in lime scale build up in hard water areas.
This should be carefully removed from the quartz sleeve with a soft cloth.
A wet test must be carried out after maintenance to ensure there are no leaks before the UVC
is reconnected.
1.
Undo the four screws on the UVC electronics cover cap
2.
Unscrew the UVC electronics cover cap.
3.
Inspect the UVC cap and quartz sleeve for water leaks.
4.
If there are no signs of leakage reverse the procedure ensuring that the cover O-ring is in place.
INSTALLATION
IMPORTANT:
A wet test of the filter under operating conditions must be carried
out before the UVC or power supply are installed.
Connect the filter to the pump following all installation instructions,
check for leaks after 24 hours.

The unit is protected by a micro-switch, which prevents the UVC light from illuminating when the
cover is removed.
In order to check that the UVC lamp is operating correctly, check the indicator window above
the cable inlet gland on the UVC electronics cover cap whilst the UVC is installed into the filter.
This operation is best carried out at dusk, as UVC lamps emit a dim blue light which can be
difficult to see in daylight.
