Instructions for Replacing Cartridge
Cartridge Type: CM1 & CTO
Please read instructions fully before replacing cartridge:
Under Bench Water Filters
: Follow all steps below.
Bench Top Water Filters
: Follow from step 3
1. Turn water supply off at tapping valve or main water supply.
Tapping valve is the fitting used to connect purifier to water pipe.
2. After turning the tapping valve off, turn on the purifier tap until the flow of water stops. This will confirm that your
water has been turned off at the tapping valve.
3. Turn housing upside down and unscrew Base from Top so cartridge may be removed (unless it is wall mounted on a
bracket). If you have difficulty unscrewing the housing, remove the tubing from the head by depressing the small ring
on the housing attachment and pulling the tube at the same time.
4.Drain water from housing, and then remove the
old
cartridge.
5.Wash out inside of housing with hot water and a small amount of normal dishwashing liquid if required. Ensure that
the housing is rinsed well to remove any soap residue.
6. Remove protective wrapping from the cartridge and place into the housing.
The direction of new cartridge is not important it filters either way.
7 .Before fitting the Base and Top together: Lubricate the O-ring with some Vaseline or vegetable oil. This will help to
seal the unit. Make sure the housing O-ring is in place and not creased or buckled before screwing together tightly.
8. Re-connect housing to water supply, turn supply on and run filter for approximately 5 minutes to
activate the cartridge. The water may have a milky look for the first few hours; this is due to millions of air bubbles be-
ing forced from the carbon.
9. How do you know when it’s time to replace your cartridge?
We place your name on a database; this allows us to remember when you received your new cartridge. We will then
remind you when it is time to replace it.
Approximate life of your cartridge: One year
The life of the cartridge will vary depending on a number of factors, i.e. manufacturers recommendation, amount of
water being used through the filter, turbid water supply, amount of sediment in the water etc. If the flow through the
filter decreases or water taste deteriorates it may be time to replace the cartridge.
