How to Replace Stage-5 Carbon Filter:
Replace this last filter at the same time you replace the stage-4 membrane.
1) Remove the OLD filter: See
Fig. 14C.
Disconnect the output tubing from
point H
and tubings at
point
G & F
. To remove the tubing, push in and hold down on the collet ring square against the fitting. With
the collet held in this position the tube can be removed.
2) Unclip the old filter from the membrane housing and discard the used filter.
3) Sanitize: Use some mild bleach solution to rinse the 2 plastic ports of the Tee fitting and the open port of
the new filter. This is to prevent contamination.
NOTE:
Only this filter change needs bleach sanitizing.
Do not
apply chlorine/ bleach in any way to
Membrane for it will damage the membrane!
4) Connect New Filter:
See Fig. 14C.
Attach the new filter onto the clips. Make sure the
“FLOW
”
arrow
on the filter is pointing towards the pure water output direction
.
Reconnect the tank yellow tubing and
clear tubing from
C4
back to
point
G & F
on the Tee fitting. Then, connect the output tubing to
point H
.
5)
Check for leaks!

6) Check for leaks!
7) Drain the first tank of water (through faucet) to flush out the new membrane!
The 2
nd
tank of
water is ready for use.
