To Clean The Grid; Regular Care Of Water Purifier; Points To Remember - Dometic RO 400 User Instructions

To clean the grid

The grid (a coarse filter) is designed to intercept large par-
ticles and is located inside the connection for the feed
water on the appliance. If the indicator lamp for filter I
shows that the intake pressure is too low, the reason may
be that the grid is clogged.
1 Turn off the tap for purified water. Disconnect
the appliance from the electrical supply.
2 Close the valve on the water supply pipe.
3 Undo the feed water hose connector on the
appliance.
4 Use suitable pliers to grip and remove the grid
(Fig. D).
5 Clean the grid and run water through it before
putting it back inside the connector.
6 Reconnect the feed water hose to the appliance.
7 Open the valve on the cold water supply pipe
and check that there are no leaks.
8 Connect the appliance to the electrical supply
again. It will flush automatically.
Listed below are the things you need to remember in the regular care of your water purifier.
The points are listed in the order of frequency, starting with daily checks.

Points to remember

• Check the indicator lights every day, in case there is
some state or function which needs attention.
• The everyday care of the water purifier consists basi-
cally of keeping it clean. The outside of the appliance
should be cleaned with a damp cloth only. Do not
use a wet cloth and do not pour water over it for
cleaning. Do not use any cleaning agents.
• Once a month check that all connections to the appli-
ance are properly secured and watertight. Wipe dry
any condensation which may have accumulated inside
the appliance base. Leakages outside the appliance can-
not be detected by the appliance's leakage protection
system.
• The appliance needs to be descaled at regular inter-
vals. The frequency depends on the hardness of the
water supply and its microbial content.

REGULAR CARE OF WATER PURIFIER

• Be sure to replace the filters as soon as necessary. The
life of these filters is determined by (amongst other
factors) the levels of impurities in your water supply.
If the water supply has been classified as unfit for
drinking, the water from the appliance should be
tested once per year.
• After replacing filters leave the discarded filter insert
to drain for a few minutes. These filters can be dis-
carded in your ordinary household refuse, since they
do not contain any substances which are hazardous
to the environment.
