The RO 400 Direct Flow is a very safe appliance, but even so it is important that everyone using
it should be thoroughly familiar with the way it works and its safety features. To prevent mishaps
and problems you should read the "
Safety Information
" on these pages, and carefully follow the
instructions in the "
Installation
" section. Take care of this manual and make sure that it
accompanies the water purifier if it is moved or sold.
SAFETY INFORMATION
• Check that the water you intend to purify meets
the requirements listed under "Requirements of
feed water", in the section "Technical data".
• When the RO 400 is brand-new, the purified
water must not be consumed until after the
calibration and flushing procedures have been
completed.
• Calibration of the RO 400 should only be carried
out:
– the first time that the water purifier is used
– if the appliance is moved to a different place
(locality) where the water quality is different
– after the membrane has been replaced
• When the RO 400 is new or the membrane
contains the special products for storage or
descaling, it will have to be cleaned by following
the "Flushing procedure" before the water from the
water purifier may be used again.
• The water produced by the appliance may only be
consumed if Purification Level indicator II or III
on the control panel was lit when it was being
purified. A green indicator light on the spigot will
come on at the same time.
Do not use the water purifier where the feed
water is microbiologically unsafe or with water
of unknown quality.
• If the feed water supply to the appliance is unfit for
consumption, have the purified water from the
appliance tested after installation. You should
subsequently have the purified water tested once a
year, or if any change in its taste or smell occurs, to
ensure that the water purifier is functioning well.
If the result is unsatisfactory, do not drink the
water. Contact your dealer.
• If any leakage arises, turn off the supply of water to
the appliance immediately and disconnect the
appliance from the electrical supply by removing
the electrical plug from the wall socket, or if
necessary, removing the relevant fuse (or switching
off a circuit breaker) at the electrical distribution
board (consumer unit).
• If the RO 400 is not going to be used for more
than four months, or if the purifier is going to be
disconnected from water and electricity for a long
period (several days), it must be protected by
following th ”Preparing the RO 400 for storage and
protecting it against freezing”.
• Do not attempt to modify or otherwise alter the
RO 400 in any way. Doing so could result in
personal injury and/or damage to property which
would not be covered by any warranty.
• Once every month you should check that the
connections are all watertight. Leakages outside
the appliance cannot be detected by the appliance's
leakage protection system.
• If the water purifier is malfunctioning, it should be
isolated from the electrical supply by removing the
electrical plug from its socket. If this is not
possible, remove the relevant fuse or switch off the
circuit breaker at the electrical distribution board
(consumer unit).
Be sure to follow applicable local plumbing
and sanitary codes when installing the RO
400 water purifier.
• At the end of the appliance's useful life, disconnect
the electrical plug from the power supply, then cut
the electrical lead at the point where it enters the
appliance. Make quite sure that children will not
be able to play with the severed lead and plug.
To find out how best to dispose of the appliance,
contact your dealer or the local authority.
