4.6 Prevention of siphoning
If the toilet is below or less than 50 cm above the waterline there
is a danger of water siphoning back into the toilet (supply pipe).
An air vent must be fitted at the highest point in the supply pipe
in order to prevent siphoning (see the installation examples).
4.7 Testing
Open the ball valve in the water supply pipe completely so that
there will be a sufficient supply of water for flushing.
The toilet is operated by the two-position switch.
• Press 'ADD WATER' until the water level in the toilet bowl is
about halfway (about 9 sec).
• Throw a few pieces of toilet paper in the toilet bowl and press
'PUMP OUT' (about 6 sec) to pump the toilet empty.
• Press 'ADD WATER' to fill the bottom of the toilet bowl with
water (about 4 sec).
The times given can be used as reference times to check that
the toilet is working properly.
Check that there are no leaks at any of the connections.
