Installation
Fig. A Always install the UVC device outside the aquarium, with the aquarium water flowing through the UVC device and
through the external filter. As the purification bacteria in the filter do not come into contact with the UV light, the
biological filtration is not adversely affected.
Fig. B Cut the hose connectors (a) on the same diameter as the diameter of the hose. Unscrew the hose connectors from
the UVC device before starting the sawing, to avoid damaging the UVC device.
• Screw the hose connectors with the rubber gaskets (b) back onto the UVC device.
• Connect the hoses from the external filter to the hose connectors of the UVC device. Secure the hoses with hose
clamps.
• Switch on the filter pump and check for any leaks.
• Then turn on the UVC device by plugging in the power cord.
Fig. C Check the operation of the UV lamp via the light indicator on the UVC device.
• To avoid UVC overheating, switch off the UVC device when no water is flowing past it.
Maintenance
• Check monthly if UV lamp is burning via the light indicator on the UVC device.
• Remove the plug from the socket before carrying out maintenance!
• The UVC device should be cleaned twice a year.
• The lamp is hot, wait 10 minutes after switch off before opening the UVC device.
• Ensure that the water is drained out of the UVC device first, before opening the device.
Fig. D Slide the red switch lock (o) to unlock the electrical part/unit head and housing.
• Turn the unit head (p) counter-clockwise against the stop and carefully pull it out of the housing.
• Clean the inside of the housing (e) with a clean brush or cloth and rinse with clean tap water.
Fig. E Loosen the locking screw (n) from the unit head, screw off the locknut (g). Pull off the quartz glass (h) including
the gasket (l) by a slight rotary movement.
• Clean the quartz glass outer face with a soft cloth and SuperFish Pump & UVC Clean carefully. After cleaning,
thoroughly rinse the quartz glass with clean tap water and check for damage. Replace the quartz glass if it shows
any damage (to prevent glass breakage). Quartz glass replacement kit for the AquaClear UVC 9W (Art. 06010350)
and for the AquaClear UVC 18W (Art. 06010355).
• The UV-lamp should be replaced yearly. Although the lamp may still burn, it no longer emits enough UV radiation
(maximum 8000 operating hours). Replacement lamp for AquaClear UVC 9W: SF UV PL-lamp 9 W G23-167 mm
(Art. 06011015) and for AquaClear UVC 18W: SF UV PL-lamp 18 W G23-236 mm SP (Art. 06010140).
Fig. F Remove the old lamp (j) together with clip (i) and tube protection ring (k) and remove the O-ring.
Fig. G Slide the tube protection ring (k) over a new UV-lamp, and put the clip (i) on the end of the UV-tube.
Fig. H Insert the new UV-lamp (j) in the fitting of the unit head.
Fig. I Slide the quartz glass (h) gently over the UV-lamp and insert the quartz glass with the gasket in the unit head.
Fig. J Slide the locknut (g) over the quartz glass and tighten it onto the unit head.
• Place back the locking screw (n) to lock the locknut.
Fig. K Place the unit head (p) with fitted UV-lamp and quartz glass back into the housing (e) correctly and lock the red
switch (o).
• Check the whole assembly for possible leaks and check if the UV lamp is working.
