1.
Shut off the cold water valve under the sink. Release the pressure from the
system by turning on the filtration system faucet. Once there is no longer any
water coming from the filtration system faucet, you will be ready to change
the filters.
2.
Unpack the replacement filter cartridges from the box & remove the plastic
wrap from the filters. You will notice that each filter cartridge is color coded
to match the cartridge sump on the filtration system.
3.
Remove each cartridge sump from the filtration system by rotating the sump
towards the left side & pull down to detach. (Fig. A)
4.
Hold the cartridge sump over the sink, separate the two pieces of the sump
by turning the bottom portion of the sump in a clockwise direction. Pour any
excess water down the drain. Pull down on each cartridge to disconnect the
filter cartridge from the top half of the sump. (Fig. B)
5.
Insert & connect the new filter cartridge to the top half of the sump then
reattach the bottom of the sump to the top half by turning & tightening
counterclockwise. (Fig. C)
6.
Reattach sump to the bottom of the top housing by making sure all
connection points are aligned, pushing the top of the sump up & into the
bottom of the top housing & turning the sump towards the right. Ensure that
the sump is fully attached and locked in. Red on left, yellow on right. (Fig. D)
7.
Once both filter cartridges have been changed and sumps are securely
attached to the top housing, slowly turn the cold water valve back on,
confirm the RO faucet is closed & allow the tank to completely fill (this may
take around 2 hours).
8.
Once the tank has completely filled, inspect for leaks.
9.
If there are no leaks, flush the filter cartridges by opening up the RO faucet
and allowing the water to run through the filters until there is no longer any
pressure coming out of the RO faucet.
10.
Close the RO faucet, allow 2 hours for the pressure to build back up in the
system and your RO system is ready to use.
