Using The Ro 400; To Draw Purified Water - Electrolux RO 400 User Manual

Once the RO 400 has been installed and calibrated according to the " Installation " instructions, it
is ready for use.
The RO 400 has an electronic control system which makes it easy for you to use. Normally you
will only need to remember a few points:
• To use the tap connected to the appliance only when you want to draw off water of good
quality, as indicated on the front panel.
• To replace Filters I and II once or twice a year, or when the indicators on the front panel show
they need replacing.
• To descale the water purifier at the intervals recommended.

To draw purified water

The RO 400 produces purified water when the tap is
moved to either of the "On" positions shown in Fig. B.
When the tap lever is moved to Position 1, the tap will stay
on (hands-free) at maximum flow until the lever is moved
back manually to the "Off" position.
The lever has to be pressed and held when Position 2 is
used (also maximum flow).
The indicator lights on the tap show the current water
quality:
• green light: optimum water purification level
• red light: unacceptable water purification level
If the RO 400 has not been used for a time, it may
take up to 60 seconds before the optimum water
purification level is reached, as shown by lights on the
tap and control panel.
The RO 400 has automatic features designed to
optimise the service life of the membrane:
• Just after you draw water each time, the appliance will
switch to flushing mode automatically, to clean the
membrane. The length of this flushing will vary (5 to 90
seconds) according to how long the tap was open.
• If the tap is left on for longer than 20 minutes, the
appliance will shut down automatically. To restart it,
follow the instructions in the "Trouble-shooting table".
• The appliance will switch automatically to flushing mode
for a brief period once every 12 hours (approximately),
provided the water and power supplies are connected.
This periodic flushing takes place no matter when the
appliance was last used.
When using the RO 400, it is sensible to fill a jug with
drinking water while it is operating. Try to avoid starting it
working just to fill a single glass at a time. This helps save
water, because each time the appliance purifies water, a
certain amount is lost (via the reject water outlet) before the
optimum purification level is reached, and the RO 400 also
switches to flushing mode after it is used.
