Replacing / Cleaning Quartz sleeve
ALWAYS ISOLATE THE UNIT FROM ANY ELECTRICITY AND WATER SUPPLIES
BEFORE CARRYING OUT MAINTENANCE ON THE UNIT.
To Replace / Clean the Quartz Sleeve:
Switch off pumps and if possible isolate the evoUV by closing any valves.
1. Drain the water from the evoUV by unscrewing the drain plug.
(You may need to bleed some air, do this by partially unscrewing the connection
on the inlet or outlet.)
2. Once completely drained, remove the UV bulb as described on page 14. You will
need to undo both end caps.
3. Unscrew the locking nuts which hold the quartz sleeve in place. Taking care not
to lose the O-rings.
4. Gently slide out the sleeve, taking care not to allow it to drop inside the UV body.
5. Clean the sleeve and polish with a soft cloth or paper towel. If you live in a
hard water area, you may get limescale on the quartz sleeve; this can be easily
removed by using vinegar or a cold water descaler.
6. Replace the quartz sleeve by sliding it back into the evoUV, ensuring that an
equal amount of the sleeve is showing at each end.
7. Slide the two O-rings back into position on each end of the quartz sleeve,
and screw on the locking nuts tightly until the seals are compressed.
8. Now replace the bulb as described on page 14.
WARNING: If the end caps / electrical connections get wet during this procedure,
please ensure that they are thoroughly dried before re-connecting.
During this procedure or if you notice water leaking from around the end caps you
should check the following:
1) Check the O-ring is undamaged.
2) Check there are no cracks and breaks in the quartz sleeve.
3) Check that the locking nut is compressing the O-ring to form a water tight seal.
4) Check that the gland nut and gland nut sleeve are installed correctly
and are tight.
5) Check that the end caps are sufficiently tight.
6) All components are clean and free from dirt and debris.
