A Residual Current Device (RCD), also known as the Residual Current

Circuit Breaker (RCCB), with a tripping current not exceeding 30mA must be installed in the

supply circuit. A means of disconnection from the supply having a contact separation of

at least 3mm in all poles must be incorporated in the wiring.

Please note all electrical work on garden lighting and power installations must comply

with part P of the building regulations. Failure to comply is a criminal offence. If the installation of this

MAINTENANCE & CLEANING

Annual maintenance

Check for wear

Once a year you should dismantle your PRO UVC. Dismantle the UVC examining all the parts for wear

or damage, replacing any parts show obvious signs of wear or damage. (see getting to know your

PRO UVC for replacement codes and parts descriptions on pages 2 and 3).

Winter storage

The UVC can be run year round if the pump flow is maintained, this is the best option. Alternatively in

winter the UVC may be switched off. Follow annual maintenance procedure and store frost-free in the

house or garage until spring.

TROUBLESHOOTING

In order to correctly identify if you have green water or cloudy/brown water, a settlement

test should be carried out.

Take a glass of pond water and allow to settle for a few hours. When the glass is stirred a

small layer of settled waste can be seen at the base of the glass. This indicates that you have

brown or cloudy water and that your UVC is working correctly. If there is no settlement it

indicates that you have green water and the UVC is not working correctly.

UVC leaks

•

Check that the UVC inlet/outlet caps and O-ring have been correctly assembled and that they are

hand tight.

•

PTFE tape may be needed to give a water tight seal and should be applied to the inlet or outlet hosetails.

•

Always secure the UVC inlet hose and outlet hose with a jubilee clip.
