If Stage 1 & 2 pre-filters are changed regularly, the Stage-3 Membrane can last 2-3 years depending on
your input water’s quality. The Membrane needs replacing when: The TDS (total dissolved solids) level
in the pure water starts to increase (detected by a TDS meter from APEC), or when the water taste qual-
ity starts to decline. A lost in water flow/pressure can be an indication of clogged filters/membrane also.
Replace the Membrane as follows:
Disconnect tubing from the Membrane-Housing
Cap. Remove membrane-housing cap by turning
it counter-clockwise. Pull out the old membrane
using pliers. Then insert the new membrane into
the housing using pliers. Make sure the end
with “2 small black rings” goes in first as
shown (See Figure D1 & D2).
Close the cap on membrane-housing.
Reconnect tubing to the cap.
Let RO run for 10-15 minutes to flush out the new membrane – discard the output water.
When done flushing, the pure water is ready for use.

Follow the same procedures as for changing the
Stage-2 carbon filter.
Disconnect tubing from Point J & Point K. To
remove the Pure water output line at Point K,
use a pair of pliers and remove the tubing lock
(red clip) (See Figure E).
Snap on the new filter onto the 2 holding clips.
Make sure the Flow direction “arrow ” on
the filter is pointing towards the right direction
(See Figure E). Re-connect tubing to both ends
of the new filter.
