3.1 I Prepare the pool
• For op mal opera on, the pool water must comply with the following condi ons:
Water temperature Between 15°C and 35°C
pH Between 6.8 and 7.6
Chlorine < 3 mg/ l
• Stop the lter pump.
• Clean the skimmer basket, the lter pump pre- lter and the lter where necessary.
• Start the lter pump.
• Start the booster pump. Bleed the water circuit for 2-3 minutes.
• Stop the lter pump and booster pump.
• Place the hose beside the pool in the sun for 2-3 minutes to unwind it. This will reduce tangling of the hose during
cleaning.
• When the pool is dirty, especially when rst installing the cleaner, remove the largest debris using a manual brush
and a net.
• Remove any thermometers, toys and other objects that might damage the appliance.
Tip : Preserve the cleaner
A er cleaning or backwashing, let the ltra on system run for at least ve minutes before connec ng the
cleaner.
3.2 I Checking the rota onal speed of the wheel
• Do not place your hair, loose clothing, jewellery etc. in the vicinity of the open end of the hose.
• Do not handle the cleaner while it is opera ng (except when checking the wheel RPM).
• Before starting the cleaner, check the rotational speed of the wheel (rpm). For maximum efficiency, the cleaner must
rotate and a speed of:
- between 28 and 32 rpm (P280-P380).
- between 32 and 34 rpm (P3900 Sport).
• Place the cleaner on its side (2 wheels in contact with the ground) and make a marking on the wheel (
).
• Install the quick disconnect on the suc on port.
• Turn on the filter pump and leave it to prime.
• Turn on the booster pump.
• Immerse the cleaner and count the number of rotations completed in 1 minute ( ).
