CARTRIDGE CLEANING INSTRUCTIONS: DOULTON
ULTRACARB (ONLY)
Water flow from the cartridge may reduce over time due to a build-up of filtration particulate contaminants (e.g. dirt,
sediment, algae, rust). To return the flow to its normal level simply remove, clean and replace the filter cartridge as
follows:
STEP 1. Removing and cleaning the filter cartridge
1. Unscrew the filter housing from the base and remove the ceramic
cartridge from the filter housing.
2. Take the cartridge to the sink and hold the cartridge under running water,
taking care at all times not to contaminate the inside of the filter cartridge
with either unfiltered water or dirty hands.
3. Scrape 0.5 to 1mm off the outer surface with a kitchen scourer.
4. Clean the inside of the housing with a food-grade sterilising solution or
white vinegar. Rinse the housing well afterwards.
5. Place the filter cartridge inside the housing. Ensure the open end of the
filter cartridge with white writing is facing UP and towards you (the filter
cartridge can only be installed one way). Make sure the rubber seals on
both ends of the filter cartridge are seated correctly.
6. Ensure that the black o-ring is properly seated in the groove of the
housing base. With the system still upside down, screw the base back
onto the housing.
STEP 2. Flush the cartridge
1. With the system still upside down, raise the spout half a turn as per
Figure 1
- ensure the spout is positioned over the sink.
2. Turn on the cold water tap and turn the diverter lever on your faucet up to
the horizontal position. Run water through the system for a few minutes.
3. Return the spout and system to its upright position
Figure 2
.
4. Your system is now ready for use.
Note: As well as periodic cleaning, the cartridge should also be replaced
every 12 months / 2300 litres, whichever comes first, to avoid a build-up of
potentially harmful bacteria.
