Instructions for Replacing Cartridge
Cartridge Type: CM1
Please read instructions fully before replacing cartridge:
1.
Turn water supply off to water purifier.
2.
After turning the water off, turn the outlet tap on from water purifier i.e cold tap until the
water stops. This will confirm that your water has been turned off, and
relieves the water pressure, inside the housing.
3.
Undo the sump of the housing. Depending on how the plumber has installed the unit the
sump should unscrew anti-clockwise from the base. Be aware that there may still be water
left inside the unit upon opening. It may be best to put an old towel under the unit to soak
up any possible spillage.
4.
Once the sump of the housing is undone, remove the old cartridge and it can now be
discarded.
5.
Wash the inside of housing with hot water and a small amount of dishwashing liquid if
required. Ensure that the housing is rinsed well to remove any soap residue.
6.
Remove protective wrapping from the new cartridge. Fit the
new
cartridge into the
housing.
If direction of new cartridge is important, we will inform you.
7.
Make sure housing O-ring is in place before refitting the base and sump together. A good
tip is to smear a small amount of Vaseline or vegetable oil around the O-ring. This will stop
the O-ring from twisting and will also help to seal the unit. Make sure base and sump are
screwed together tightly.
8.
Turn water supply on and check the unit is sealed correctly.
