• Insert the UV-C lamp, included into the package, following the instructions on the lamp replacement (see paragraph Va).
• Take a corrugated hose with the desired diameter, taking into account that the adaptors supplied in the package allow
assembling hoses with diameter of 13/20/25 mm (PL UV-C 7-9-11-18W) or 32/40mm (PLUV-C 24-36-60W). It is also
recommended to place PURE LIGHT UV-C filter at the minimum distance of 2 m from the pond edge and to divide the corrugated
hose into 2 parts of the same length.
III.a ASSEMBLING OF CONNECTING PARTS
1. (PUMP --> UV-C FILTER):
i. Cut the adaptors depending on the hose diameter you use (Fig. 8) and insert them into the corresponding screw ring.
ii. Connect the end of one of the 2 pieces of the corrugated hose to the pump outlet intended for immersion into the pond.
iii. Connect the other end of the same corrugated hose to one of the 2 adaptors, previously cut- and installed, pressing it until
the hose adjoins the adaptor base. Fasten all components with a screw-clamp
iv. Install a gasket into the adaptor nut, ensuring it adjoins the bottom of the same nut.
v. Screw the assembled adaptor to one of screw nozzles located on the PURE LIGHT UV-C filter body (Fig. 9).
For 24W-36W-60W models, the tubes can be connected in two different ways (Fig. 9). The unused outlet must be closed with
the specific cap.
2. (UV-C FILTER --> POND PUMP)
i. Connect the other adaptor previously cut and installed as mentioned above, to a free end of a second piece of corrugated
hose, pressing it until the hose adjoins the adaptor base. Fasten all components with a screw-clamp.
ii. Install a gasket into the adaptor screw ring, ensuring it adjoins the bottom of the same nut.
iii. Screw on the assembled tip to one of screw nozzles located on the canister of PURE LIGHT UV-C filter (Fig. 9).
iv. Immerse the free end of the corrugated hose into the pond.
III.b FIXATION OF FILTER TO FIXED SUPPORT
The PURE LIGHT UV-C filter is equipped with special fixing devices located on the filter body ensuring secure mounting to any
surface (Fig. 10)
To do this, follow these instructions:
i. Choose a support, the most appropriate for this purpose, such as metal, stone, ceramic or wooden plate.
ii. Put the UV-C filter on the support, search the points next to the hooks on the filter body and mark them with a pencil
iii. Drill holes in the support and fix the UV-C filter.
It is recommended to install the filter in such a manner that it cannot get into the water accidentally, make sure the area, where it is
installed, is not subject to flooding, and that the distance between the filter installation point and the pond edge is minimum 2 m.
IV. PERFORMANCE
IV.a
SWITCHING ON/OFF
After the filter is fixed on a stable base or fixed support, as described above, it can be switched on. For this purpose, follow the
instructions below:
i. Make sure that all electrical sockets comply with the applicable local standards.
ii. Insert the plug of the pump, previously immersed into the pond, into the socket: it will start working immediately.
iii. Insert the plug of the UV-C filter into the socket: it will start working immediately.
iv. Proper functioning of the UV-C filter is demonstrated by blue light on the transparent adaptor. Otherwise, refer to
section
VI – TROUBLESHOOTING
.
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). It is recommended to pay utmost attention when performing maintenance, to avoid damages which
