After taking the housing off, take out the dirty filters and
put the new 3 pre-filters in. Remember, Stage 2 and
Stage 3 use the same carbon filters.

3) Discard 3 used filters, wash housings with mild soap, rinse off. Put 3 new filters into their respective
housings: sediment filter in stage-1, carbon block filters in stages 2 & 3.
4) Close up the housings. Make sure each housing has a
black O-ring in the threaded groves. First hand
tighten the housing, then use filter wrench to fully tighten each housing. Do not over-tighten.
5) Keep tank ball valve CLOSED and Turn ON the cold water supply as well as RO faucet lever. Please let
purified water run for 10-15 minutes to relieve built-up pressure inside the RO unit.
6 ) Turn OFF the RO faucet lever and Turn ON the tank ball valve.
7) Check for leaks!
How to Replace Stage-4 Membrane:
1) Turn OFF the cold water supply to RO system. Turn OFF tank ball valve. Turn on RO faucet lever briefly
to relief the built-up pressure inside the RO system. This will make opening the housings easier.
2) See Fig.14C Page 21. 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.14A . Using a plier, remove the used membrane for dispos-
al.
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.14B . The membrane cannot filter water if it’s inserted in the WRONG direction!
