.
To switch PURE LIGHT UV-C filter off, simply disconnect the plug from the socket. Do not pull the power cord to avoid its possible damage.
V. MAINTENANCE
WARNING
: The PURE LIGHT UV-C filter is equipped with a protective device that automatically switches the lamp off if the filter
head is accidentally opened without disconnecting it from the socket. The device is activated by means of a pivot located on the
filter body basis (Fig. 11 page 6). It is recommended to pay utmost attention when performing maintenance, to avoid damages
which may require replacement of the entire filter.
WARNING:
Prior to maintenance of the appliance, you must disconnect the plug from the socket.
To ensure optimum performance of the filter, it is recommended to replace the lamp every 5000-6000 hours, depending on the
season, when used in ponds, and every 8-10 months – when used in aquariums.
