How to Replace Stage-3 Membrane:
1) Turn OFF the cold water supply to RO system. Turn OFF tank ball-valve. Lift up RO faucet lever briefly to
relief the built-up pressure inside the RO system. This will make opening the housings easier.
2) See Fig. 1. Locate the Membrane housing on the system (labeled “Membrane”). Remove the WHITE
tubing from the housing’s cap at point D. To remove 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. Open up the cap
(turn counter-clockwise) See Fig. 2. Using a plier, remove the used membrane for disposal.
3) Once the membrane is removed, please tilt the RO system at an angle to drain out residual water from
inside the membrane housing and insert the new membrane using a plier. Push membrane into housing.
Avoid touching the Membrane with your hands to prevent contamination!
4) Important! Make sure the “double-ring” end of the membrane goes into the housing first as shown in
Fig. 3. The membrane cannot filter water if it’s inserted in the WRONG direction!
How to Replace Stage-4 Carbon Filter:
The Stage-4 Pre-Carbon filter is located above the 1st stage sediment filter (See Fig. 1).
For ease of access, please tilt the filters to a convenient position then do the following:
Step 1. Disconnect tubing from Point H & Point J, discard used Filter.
Step 2. Snap on the new filter onto the 2 holding clips. Make sure the Flow direction “arrow ”
the filter is pointing towards the output direction. Reconnect tubing to both ends of the new
filter.
Add a little bit lubricant on double o-rings.
Turn counter-clockwise to
open the membrane
housing cap.

NOTE: The QC fittings come with an End Plug that needs
to be removed before the tubing can be connected.
