APEC R.O. System Filter Change Instruction

Changing Stages 1, 2, 3 Pre-Filters: (should be changed at least every 12 months)

1) Turn OFF cold water supply to RO system. Turn OFF the 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) Open housing: Have the RO standing upright. Slip the plastic wrench onto the #1 housing. Looking down from a top view,

you should open the housing turning clockwise. If necessary, lay RO down on the floor to get a better leverage. If the

housing is too tight, use a hammer and tap on the wrench handle to help turn the wrench.

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 thread groves. Use wrench to tighten each

housing.

5) Remember: Turn ON the cold water supply and OPEN the tank valve after finished changing filters!

6) Check for leaks!

Changing Stage-4 Membrane: (should be changed every 3-5 years)

1) Turn OFF the cold water supply to RO system. Turn OFF the 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. B1. Locate the Membrane housing on the system (labeled “Membrane”). Remove the RED tubing from the

housing’s cap at point D. For Quick Connect fitting, 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. For threaded fitting, unscrew the plastic nut (not the L-shape

fitting) and pull out tubing. Open up the cap (turn counter-clockwise). Remove the used membrane. Discard. Insert the new

membrane using a pair of pliers. Push membrane into housing tightly. Avoid touching the Membrane with your hands to

prevent contamination!

3) Important! Make sure the “double-ring” end of the membrane goes into the housing first as shown in Fig. A. above. The

membrane cannot filter water if it’s inserted in the WRONG direction!

4) Close the housing cap. Reconnect the RED tubing to the cap. Turn on the cold water supply and open the tank valve. Let

the RO system run to re-fill the tank (takes about 2-3 hours).

5) Check for leaks!

6) Drain two tanks of water (through faucet) to flush out the new membrane! The 3rd tank of water is ready for use.
