Prepare filter for use
1. With the user faucet open, slowly turn on the mains water to allow the system to
fill gradually and run the filtered water to waste for 10 minutes (or 15 litres).
2. Close the faucet and check for leaks.
3. Leave to stand for 24 hours to condition the ceramic filter element, then run
water to waste for a further 10 minutes. The filter is now ready for use.
Servicing the filter - removal of the filter element
1. Grip the textured rim of the grey filter cap, twist to the ‘unlock’ position, taking
care not to trap fingers and pull down to disengage -
see figure 7
.
Note:
If filter
has had little use prior to servicing, twist to the ‘V’ vent position and open the user
faucet (to relieve pressure in the filter) twist the grey cap to the ‘unlock’ position
and pull down to disengage the filter whilst the faucet remains open.
2. The water supply is automatically turned off when the filter is dismantled.
Note:
If filter is to be left unattended whilst dismantled for an extended period of
time (i.e. over 1 hour) then the upstream mains water supply should be isolated.
3. Take the filter cartridge to the sink - remembering that it is still full of water.
4. Unscrew filter cap to remove the filter body and empty the water into the sink,
taking care not to contaminate the open ended neck of the filter cap with
unfiltered water
5. Disconnect the filter element by either twisting and pulling or unscrewing
(depending upon the type of element used) whilst holding the filter cap. Care
must be taken to prevent contamination of the neck of the filter cap and filter
element mount stem.
6. Replace the filter element or clean as described in the following section and then
wash your hands.
Note:
If replacing with a new filter element, prepare the filter for use as described
in the ‘prepare filter for use’ stage above, or as per the Operating and Exchange
Instructions supplied with the filter element.
Cleaning the filter element - figures 8 & 9
Due to filtration of particulate contaminants from the water during use, the flow of the
water from the filter may reduce over a period of time. To restore the water flow to it’s
normal level, simply clean the cartridge as follows:
Hold the filter element in a bowl of water or under running water, taking care to ensure
that the open ended plastic mount is clear of the water - to avoid contamination -
see
figure 8.
Take a clean kitchen scouring pad in one hand and cup it around the circumference of
the filter element at the top - next to the mount.
Press gently onto the candle surface with the kitchen pad, whilst quickly turning the
element with the other hand.
Applying a gentle even pressure with the scouring pad slowly work down the length of
the filter element once, ensuring that the cleaning is uniform over the whole candle -
see figure 9.
