CAUTION: Always isolate the unit from the electricity and water supplies before carrying out any maintenance on
the unit.
1. Loosen the screws and remove the blue end covers from either end of the unit. Carefully pull off the white plastic
electrical lampholder.
2. Carefully slide the lamp out of the unit. Next, unscrew the two compression fittings located at either end of the
main body (see diagram) and slide off the two "O" rings from either end of the quartz sleeve.
3. Carefuly slide out the quartz sleeve.
4. Clean the sleeve and polish with a soft cloth or paper towel. If you live in a hard water area there may be some
limescale on the quartz sleeve; this can be easily removed by soaking the sleeve in a proprietary plastic kettle
descaling solution. Failure to remove the limescale will limit the effectiveness of the UV lamp.

6. Ensure that you locate the two "O" rings carefully on the ends of the quartz sleeve. Failure to do so will result in
leaks when the water is turned on. If you are carrying out the annual lamp change, use new "O" rings.
7. Hand tighten the compression fittings. Replace the lamp or fit a new one.
8. Relocate the white electrical end caps onto the pins of the lamp and slide the rubber endcaps over the compression
fittings.
9. Reconnect and turn on the water supply, carefully checking for any leaks before switching on the electricity supply.
