• Do not let children play with the water purifier.
• Never leave packaging material lying around so that children
can play with it.
use
• The water purifier is intended to produce water for applica-
tions that require purified water.
• Purified water should only be used when the control panel's
lights II or III (purification levels) are lit. It can take up to 60
seconds before the water purifier indicates good water quality.
• The water purifier must be connected to water and electricity
in order for the automatic flushing system to work. Automatic
flushing takes place approximately every 12 hours.
• The top of the water purifier should not be used as a place for
storing anything.
• Do not use purified water in aluminium vessels. There is a
risk of corrosion of the vessel and a higher concentration of
aluminium in the purified water.
• Do not change or modify the water purifier in any way. This
can result in personal injury and/or damage to property which
is not covered by any warranty.
• If the water purifier is to be disconnected from water and
electricity for an extended period (several days), it should be
stored, see " in the user manual. This also provides
STORAgE"
protection against freezing.
• The water purifier may not be used without prefilters (un-
less otherwise specified in maintenance procedures, see user
manual). It could be seriously damaged.
• If the water purifier contains chemicals from maintenance
procedures, it must be flushed before the purified water may
be used, see "
flUShINg"
• Once a month, check that the connections are watertight.
Leaks outside the water purifier cannot be detected by the
internal safety system. If leakage occurs, immediately switch
off the water supply and break the current to the product by
pulling the plug out of the wall socket or remove the correct
fuse in the electrical distribution board.
• If the mains lead has been damaged in some way, it must be
replaced by a qualified person to avoid damage or injury.

• Once a month, check that all the connections are in place and
are watertight. Wipe off any condensation that has collected
on the base plate.
• Make sure that you always replace prefilters in time. The
lifetime of the prefilters depends on your feed water.
• Depending primarily on the hardness of the feed water and
its content of microorganisms, the water purifier should be
cleaned when the flow is reduced or at least every 6 months
and disinfected if the water smells or tastes bad.

RO400a/RO400B
The model name for RO400A is actually RO400 (without
letter). The A is added in this document to distinguish from
RO400 when used as a family name.
RO400A and RO400B are domestic models. Most functions
and features are however common with the commercial (c-)
models.
• The water purifier is designed to produce the quantity of wa-
ter normally required for cooking, drinks, washing dishes and
general household duties.
• The water purifier may only be installed with the drinking
water faucet supplied with the product.
• The water purifier must not be connected to supply the whole
dwelling with water. Neither may the water purifier be in-
stalled in connection with valves, switches or tanks. Be aware
of the risk of corrosion in water pipes and water heaters.
• Any faults that arise in a water purifier that has been incor-
rectly installed are not covered by any warranty.
RO400B/RO400BC/RO400BCV
(BRaCkisH mOdel)
Brackish (B-) models are used when the inlet water has a high
content of salt, more than the maximum level for normal, sweet
water models, up to a maximum of 7,500 ppm (mg/l).
It might be wise to chose the brackish also if the salt content is
just below limit, if it is known that the value varies widely over
time.
Sea water cannot be purified with these models, even if the
purification technology is the same.
Especially important remarks for the brackish models:
• It is very important that the purifier is always connected to
water and electricity. Brackish water often contains organic
materials that will increase the bacteria growth. To prevent
this an automatic flush is performed approximately every 12
hour.
• concerning the installation, the material in all components at
the inlet- and drain connections must be resistant to corrosion,
for example in plastic or stainless steel.
