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:
1. Unscrew a gland nut from one end of the evoUV. This will be the end where
you want to remove the UV bulb / quartz Sleeve.
2. Unscrew the end cap from the same end of the evoUV and slide the end cap
down the cable.
3. Gently pull the bulb socket away from the UV bulb at the exposed end,
taking care not to disturb the quartz sleeve.
4. Carefully take the old bulb out, taking care not to disturb the quartz sleeve.
5. Now remove the gland nut from the other end of the evoUV.
6. Unscrew the end cap containing the bulb socket from the same end
of the evoUV.
7. Place the two end caps containing the bulb sockets out of the way on top of
the evoUV.
8. Carefully remove and keep safe the two O-Rings from quartz sleeve. There may
be some water that drains from the unit.
9. Gently slide out the sleeve, taking care not to allow it to drop inside the
UV body.
10. 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.
11. Replace the quartz sleeve by sliding it back into the evoUV, ensuring that an
equal amount of the sleeve is showing at each end.
12. Slide the two O-Rings back into position on each end of the quartz sleeve.
13. Now carefully slide the bulb back inside the quartz sleeve.
WARNING: If the end caps / electrical connections get wet during this procedure,
please ensure that they are thoroughly dried before re-connecting.
14. Attach one bulb socket to one end of the bulb.
15. On the same end screw on the end cap, but not the gland nut, finger tight only.
16. Now install the bulb socket, end cap, sleeve and gland nut at the opposite end
of the bulb – FINGER TIGHT ONLY.
17. Screw the gland nut on to the other end cap.
