Changing Stages-1, 2, 3 Pre-Filters: (should be changed at least every 6-12 months)

1. Turn OFF cold water supply to RO system. Turn OFF the tank ball valve. Turn on the RO faucet lever briefly to relieve 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 1st 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 housings is too tight, use a hammer and gently 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 threaded groves. First hand tighten the housing, then use a 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!

After Taking the housings 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.

Turn counterclockwise to open the membrane housing cap.

Changing Stage-4 Membrane: (should be changed every 2-3 years)

1.  Turn OFF the cold water supply to RO system. Turn OFF the tank ball valve. Turn on RO faucet lever briefly to relieve the built-up pressure inside the RO system. This will make opening the housings easier.
2.  See Fig. B. Locate the Membrane housing on the system (labeled “Membrane”). Remove the WHITE tubing from the housing cap at point D. 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. Open up the cap (turn counter-clockwise) see Fig. A1. 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 of 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. A2. above. The membrane cannot filter water if it’s inserted in the WRONG direction!
5. Close the housing cap. Reconnect the WHITE tubing to the cap. Turn on the cold water supply and tank valve. Let the RO system run to re-fill the tank (takes about 2-3 hours).
6. Check for leaks!
7. Drain the first tank of water (through the faucet) to flush out the new membrane! The 2nd tank of water is ready for use.

Changing Stage-5 Carbon TCR Filter: (should be changed every 2-3 years). The new stage-5 carbon filter (5-TCR-QC) includes a new Tee Fitting on one end. The stage-5 filter is easily replaced by disconnecting the tubings from the old filters and connecting the filter.

1. Remove the OLD filter: See Fig. B. Disconnect the output tubing from point H and tubings at points 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 1 plastic port 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 the Membrane for it will damage the membrane!

4. Connect New Filter: See Fig. B. Attach the new filter to 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!

Changing Stage-6 PH Filter: (should be changed every 6 months).

1. Turn OFF cold water supply to the RO system. Turn OFF the tank ball valve by turning the blue handle 90 degrees. Turn on the RO faucet briefly to relieve the built-up pressure inside the RO system. This will make removing the tubing easier.
2. Remove the CLEAR outlet tubing at point P See Fig. B. 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 tubing can be removed. Once the outlet tubing is disconnected, please remove the inlet tubing at point O. Remove old filter and discard.
3. The new PH filter will come with 2 End Plugs. Please remove the plugs before connecting the tubing to the filter.
4. To reconnect the tubing to points O and P, push the tubing into the Quick Connect fitting, then gently pull back on the tubing to make sure the connection was secure. Make sure “FLOW “ on filter is pointing to the drinking water faucet.

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