The Flushing Procedure; Calibration; Moving The Water Purifier - Dometic RO 400 User Instructions

The flushing procedure

You have to work through the steps of the flushing proce-
dure when the water purifier:
• is brand-new and has never been used before
• is being brought back into use after having been
stored using the Preservative/Antifreeze liquid
• has been cleaned, to wash away the cleaning agent
• has been fitted with a new membrane
No water from the appliance should be con-
sumed until you have completed the full
"Flushing procedure".
First check:
- that the drinking water tap is turned off
- that the shut-off valve on the cold water pipe for
the feed water is open
- that there are no leaks at the connection
between domestic water supply and appliance
- that the reject water and purified water hoses are
connected, with no leaks
- that the filter containers are properly tightened
1 Remove the electrical plug from the wall socket.
2 Connect the electrical plug to the wall socket
again. The water purifier will now switch auto-
matically to flushing mode.
3 When it stops, pull out the electrical plug, then
plug it back in to make the appliance go through
another flushing cycle.
4 Repeat step 3, so the appliance goes through a
third flushing cycle.
5 Turn on the purified water tap, and leave it run-
ning for ten minutes. Then turn the tap off. The
appliance will switch automatically to flushing
mode again.
... when the appliance is brand-new, or when the mem-
brane has just been replaced:
6 Follow the calibration procedure described below.
... when just flushing:
6 Repeat step 5 above.
The water purifier will now be ready for use!

Calibration

The water purifier needs to be calibrated specifically for
your water supply, to ensure the correct purification level.
Calibration should only be carried out when:
• the water purifier is new and has never been used
before
• the quality of the water supply has changed for
some reason, such as if you move the appliance
to a different locality
• the membrane has just been replaced
The water produced by the appliance during the
calibration procedure must not be consumed!
To calibrate the water purifier:
1 Turn on the tap for purified water. Leaving the
tap running, you must now – within 10 seconds
– press the calibration button (see Fig. A) and
then keep it pressed until the indicator lights for
Purification Levels I and II come on and then go
out. Then release the button.
A
If any of the Purification Level lights I-III
stay on (lit), check the five points under the
heading "First check:" in the section "The
flushing procedure", then start the calibra-
tion procedure again from the beginning.
2 Allow the appliance to go on producing purified
water for at least 10 minutes. The lights for
Purification Levels I and II will now flash once
and the current water quality level will be dis-
played when the light for Purification Level III
comes on and remains lit, indicating the highest
purification level.
If the lights for Purification Levels I, II and
III flash intermittently in sequence, this
means that calibration has not been carried
out properly. If so, start again from step 1 of
this "Calibration" procedure.
3 Turn off the tap for drinking water. The appli-
ance will switch to flushing mode, then stop
automatically.
The water purifier will now be ready for use!

Moving the water purifier

If you move the water purifier to a different location, you
must observe the following points:
• Close the shut-off valve on the cold water supply
pipe.
• Disconnect the electrical plug from the socket.
• Always transport the appliance in its normal
upright position.
• To re-install it, follow the original installation
instructions.
• The appliance will only need to be recalibrated if
the water supply is of a different quality, or if the
membrane has been replaced.
If the appliance is to be stored without being
used for longer than 4 months, see section
"Preparing the water purifier for storage".
