Using The Water Purifier; To Draw Purified Water - Dometic RO 400 User Instructions

Once the water purifier has been installed and calibrated according to the "Installation" instructions, it is
ready for use.
The water purifier has an electronic control system which makes it easy for you to use. Normally you will
only need to remember a few points:
• 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 water purifier 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 water purifier has not been used for a time, it may
take up to 60 seconds before the optimum water purifi-
cation level is reached, as shown by lights on the tap and
control panel.
The water purifier has automatic features designed to opti-
mise 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 appli-
ance 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 (approxi-
mately), provided the water and power supplies are con-
nected. This periodic flushing takes place no matter
when the appliance was last used.
When using the water purifier, 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 water purifier also switches to flushing
mode after it is used.
