7. MAINTENANCE OF THE UV REACTOR
UV lamps and quartz sleeves must only be handled with protective gloves to avoid leaving any marks
that could alter the quality of the UV emissions and protect your hands in case of broken glass.
7.1. Lamp change procedure
Ultraviolet lamps are designed to last 16,000 hours depending on the number of times they are switched on, which is
approximately 3 years for a seasonal outdoor pool or 1 years for a 24-hour indoor pool.
In order to avoid premature wear and tear, only one start-up per day, i.e. one filtration cycle, is recommended. This
will also preserve the filtration pump.
1) The electronic unit must be turned OFF.
2) Leave the lamp to cool for 15 minutes before handling if the device was in operation.
3) Unscrew the nut on the UV lamp.
4) Remove the lamp, disconnect it from the cap and place it on a clean and soft surface. Do this carefully
without touching the glass of the lamp with your hands. Do not drop the lamp into the quartz sleeve, as this
could break and damage the quartz.
5) Pick up the new lamp, avoiding leaving fingerprints on it (If this occurs, clean with a soft cloth and
methylated spirit).
6) Reinstall the lamp into the reactor (see section 6.4) and start
7) Reconnect the device and turn it back on. The device is ready for use.
7.2. Dismantling the quartz sleeve
Every year the quartz sleeve needs to be checked to ensure that it is not clouded by limescale deposits. It must be
perfectly transparent so that ultraviolet rays are not obstructed.
1) The electronic unit must be turned OFF, and the reactor ISOLATED from the hydraulics (by-pass valves
shut).
2) Remove the lamp (see previous paragraph).
3) Pick up the quartz sleeve to remove it completely from the reactor.
4) If whitish limescale deposits are present, cleaning will be necessary. This operation must be performed using
white vinegar or an acid and a soft cloth. The quartz must not be scratched, as this would alter the
ultraviolet radiation. Be careful not to let go of the quartz sleeve until it is in its housing, otherwise it could
break or be difficult to retrieve.
5) Wearing suitable gloves, insert the quartz sleeve into the device until it is in its housing at the base of the
reactor.
6) Replace the lamp into the reactor (see section 6.4).
7) Return the installation to operation and check that there are no leaks; if this is the case, check the nuts are
tight.
