REFILLABLE DEIONISATION CARTRIDGE
1. Begin by removing the cap from the cartridge and setting the cap & foam insert aside.
2. With the cartridge on a
fl
at working surface, begin
fi
lling the cartridge with DI resin by slowly
shaking and tapping the bag, avoiding any spills.
3. Once you have
fi
lled the cartridge 3/4 of the way, stop and give the cartridge a few gentle taps
on a bench top to make sure that the resin is packed as tight as possible.
4. Continue
fi
lling the cartridge. Once completed, tap it a few more times to ensure it is packed
tightly, making sure that you have left enough room for the foam insert and cap to replaced,
about half a centimetre.
5. Make sure the threads are clear of any resin beads before replacing the foam insert and cap.
This will make it easier to screw the cap back on as well as ensure a water tight seal.
6. Using the palm of your hand, apply even pressure to the cap whilst screwing it back on.
7. When installing the DI cartridge into the housing, ensure that the rubber seal is on the top facing
up.
FILTER INSTALLATION INSTRUCTIONS
Packing the resin as tightly as possible is critically important to reduce the risk of
channelling during the production of water. Channeling will allow high TDS water to
bypass the the resin during water production.
!
The frequency in which you will need to replace your Carbon & Sediment pre-
fi
lters will
vary dramatically based on the the quality of your home’s tap water and how much
water you have produced/
fi
ltered with the system. We recommend changing your
pre-
fi
lters every 6 months as a general rule.
