I have just installed ZERO, but no
water comes out when I open the tap.
Check that you have not reversed the input
and output pipes.
If the system does not supply water, check if the
inlet and outlet pipes (both white 8 mm pipes) have
been installed correctly. A sticker on the ZERO
clearly indicates where to insert the IN and where
to insert the OUT.
If the system has been commissioned with inverted
tubes, remember that the supply pipe is under
pressure, thus making the operation of detaching
the pipe more difficult.
Check that the pre- and post-cartridges
are in place.
The labels on the pre- and post-cartridges must
be facing upwards when correctly installed. If one
of the two is not fully rotated at 45°, the respective
safety check valves will not open, preventing the
passage of water.
Check the input line to the ZERO.
Check that there is hydraulic power supply to
the ZERO and that the dynamic input pressure is
greater than 2 bar. If it is not possible to carry out
the pressure check, call a specialized technician.

ZERO Troubleshooting guide
The quality of the water coming out
of ZERO is not as expected
Check whether the flow restrictor in the drain
line is used in accordance with the hardness of
the instruction manual.
It is not recommended to use the flow restrictor,
which came in the box with ZERO, if the conditions
of the incoming water do not comply with the
recommendations in the installation guide, as this
may cause fast clogging of the filters.
Check that ZERO has not been installed on the
hot water line.
ZERO should never be installed on the hot water
line, as neither the structural seal of the system nor
the optimal functionality of the filters and osmotic
membranes can be guaranteed.
Check the quality of the water entering ZERO.
Do not use ZERO to filter water unless declared
drinkable by the National Health Service. The
quality of the filtered water cannot be guaranteed if
the incoming water is not drinkable.
Check that routine/annual maintenance has
been carried out on ZERO.
Do not use the cartridges for more than one
year from the moment the water enters for the
first time, otherwise the quality of the pre- and
post-treatment cannot be guaranteed. Poor
pre-treatment would significantly affect the
durability and functionality of the reverse osmosis
membranes. For each change or a cartridge, it is
strongly recommended to sanitize the equipment.
This must be done by a specialized technician.
Check that the sanitizing procedure has been
carried out correctly.
The system must be sanitized with non-
chlorine-based products only, as chlorine can
cause a quicker deterioration of the reverse
osmosis membranes. It is recommended to use
SANI:CLEAN for sanitizing.
