MAINTENANCE
Cleaning the grid
The grid blocks larger particles and is situated by the feed connection. If the “filter I” light for blocked filter or
low inlet pressure is lit, the grid may be blocked.
1. Pull out the plug.
2. Close the shut-off valve at the water connection.
3. Disconnect the feed water hose from the water
purifier.
4. Using pliers or similar, grip and pull out the grid in
accordance with fig. G.
5. Clean out and rinse before replacing the grid in the
inlet (turn the mounting for the pliers outwards),
see fig. G.
6. Screw on the feed water hose.
7. Open the shut-off valve and check that no water
leaks.

INDICATION FAULT CAUSE REMEDIAL ACTION
Time to replace filter or clean the
grid. •
There is time before the water purifier
experiences an emergency stop. Prepare to
replace filter I and to clean the grid.
The feed water’s pressure is too
low, i.e. less than 1.5 bar
(150 kPa).
•
Check the feed pressure. If necessary, increase
the pressure to 1.5–10 bar (150–1000 kPa)
Alarm for blocked filter I or II. •
Check that there is nothing in the filter containers
that is obstructing the water flow.
•
If necessary, replace filter I or II.
Alarm for dirt in the grid.
•
Check the grid according to “Cleaning the grid”.
Alarm for water
leak/condensation on the base
plate under the pre-filters.
•
Check that all the connections are watertight.
•
If there is water on the base plate, lean the
appliance forward and wipe it up.
The feed water’s pressure is too
low, i.e. less than 1.5 bar
(150 kPa).
•
A pressure increase pump for the feed water can
alleviate this.
•
Check the parts that can affect the feed water’s
pressure (water line, coarse filter, extra pre-filter).
Warning about used filter.
•
Change filter II in accordance with “Replacing the
filters”.
Alarm for poorer water quality.
•
If the water purifier is new and not yet calibrated,
rectify according to the section “Calibration”.
•
Pull out and reconnect the plug so that the water
purifier flushes. Repeat this procedure two or
more times.
