Instructions / Assembly

Adding an Acid Neutralizing Filter (PH Plus Kit)

To Your R.O. System

1. Shut off Cold water supply to RO system. Close the tank valve. Turn ON the drinking water faucet to release pres-

sure in system.

2. Fittings: The fittings on the In and Out ports of the filter are the Quick-Connect type fittings. To connect, sim-

ply push the tubing into the fitting tightly. To disconnect, push in and hold down on the “collet” ring (a moveable

sleeve) at the filter port, and pull out the tubing.

3. Remove protective plug from both ends of the pH filter (See Fig. 4). Make sure the “Flow --->” arrow on the pH

filter points to the pure water output direction (to drinking water faucet). If you need to make a longer connec-

tion, extra 1/4” or 3/8” tubing and quick connect union connector are provided.

4. Connection Option 1: To add the pH plus filter onto your RO system

• Cut the water line between Point H and Z, which originally connects the stage-5 filter to the

drinking water faucet. (See Fig. 1).

• Connect Point H to O (In port of the pH filter).

• Connect Point P to Z (Out port of the pH filter). Use the two clips provided to mount pH filter

onto stage-5 filter. (See Fig. 2).

5. Connection Option 2: To add the pH plus filter to the line

• Cut the water line between Point H and Z. (See Fig. 1)

• Add the pH filter to the line (shown as FI-PHPLUS). Please Note: Due to the weight of this filter,

please lay this filter on a flat surface. Do not let it hang on its own weight. (See Fig. 3).

6. Turn on Cold water supply to RO system.

Open the tank valve.

7. Flushing:

Flush 2-3 gallons of water through filter before

using the filtered water.

The pH filter should be added to your R.O. system as a Stage-6 Specialty Filter. Add this filter between the Stage-5

filter and the dispensing faucet as shown in Fig. 2 and Fig. 3.

Connect the Acid Neutralizing filter as follows: See Diagram Below
