BIO-UV
The ultraviolet lamps are designed to last for 13,000
hours or be switched on 1,000 times, i.e. approximately 2
years for a seasonal outdoor pool, or 1 year for an indoor
pool operating 24 hours a day.
In order to prevent premature wear, it is recommended
that they be switched on (i.e. 1 filtration cycle) once a
day which will also preserve the filtration pump.
Changing the lamp:
It is essential to work with the
lamp
stopped.
Whether the equipment is installed vertically or
horizontally, check that there is sufficient space to
remove the lamp in the equipment room.
Disassembly (see part numbers on the diagram on
page 7-8)
- Remove the unit (22).
- Take hold of the 4-pin connector (21) and gently pull
the lamp upwards rotating it.
- As soon as the lamp is a few centimetres out,
remove the connector, take hold of the ceramic base and
disengage the lamp from the quartz sleeve keeping it
correctly in the axis.
- Carry out the operation with care.
Do not drop the lamp in the quartz
sleeve as it could break and damage
the quartz.
Re-assembly
- Take hold of the new lamp, avoiding touching it with
bare fingers outside the upper and lower ceramic bases
(if you do touch it, clean it with a soft cloth using
methylated spirits).
- Engage the lamp in the quartz sleeve, keeping it
correctly in the axis, inside the equipment.
- Having engaged it ¾ of the way in, connect up the
lamp using the connector (21) on the lamp's 4 pins,
making sure you get it the right way round (locating pin).
Do not force it.
- Engage the lamp fully inside the quartz sleeve.
- Refit the unit (22).

Cleaning the quartz sleeve:
Every year you must check that the quartz sleeve has not
become opaque due to scale deposits. It should be
completely transparent so as not to reduce the amount of UV
radiation passing through it.
- Stop the filtration and work with the lamps off.
- Close all the valves on the installation.
Dismantling the quartz sleeve
WARNING: they are not guaranteed
against breakage.
-
Remove the lamp (see previous paragraph).
- Place it on a soft surface where it cannot get broken.
- Undo the stainless steel nut by hand (16)
- Remove the plastic washer (15),
- Insert your thumb or a finger into the sleeve, and gently
slide it until the O-ring (14) disengages from its housing.
- Take hold of the quartz sleeve in order to fully extract it
from the equipment ensuring that it remains aligned with
the equipment's axis.
If the sleeve is clean and completely transparent: reassemble
it in accordance with the instructions below.
If whitish calcium deposits are present, you must clean it. This
is done using spirit vinegar or acid and a soft cloth. The quartz
must not be scratched as this would change the
ultraviolet radiation qualities.
Re-assembling the quartz sleeve:
-
Carefully insert the sleeve in the equipment, keeping it
aligned with the equipment's axis.
- Using your finger inside the sleeve, position the quartz in
its holder at the bottom of the equipment. The quartz should
protrude slightly (by the thickness of the O-ring), it should not
fall right to the bottom. If the quartz is correctly positioned in
the holder, when it is pressed it feels springy (pneumatic
effect).
- Position the O-ring (14) around the sleeve having moistened
it beforehand. Push it fully into its housing using your nail (do
not use any tools).
- Place the plastic washer (15) inside the stainless steel
thread.
- Retighten the stainless steel nut (16) by hand, tightening
normally.
- Refit the lamp (see previous paragraph).
- Refit the unit (22).
- Reconnect.
