900NF Acid Neutralizing Filter Replenishment Procedure

The neutralizing media that adjusts the pH level of the water must be refilled periodically (annually). Typically,

this media is calcite and is available from WaterBoss

. To refill the neutralizing media, measure the appliance’s

media bed depth upon installation (factory freeboard). Use this measurement to determine the amount of media

to add to maintain optimum performance of the 900NF.

Tools and Materials Needed

The following tools and materials are needed to replenish the neutralizing media:

 Analog scale (do not use digital)  1/2-inch (1.3 cm), 4-ft (1.2 m) siphon hose

 Steel tape measure  Funnel with 1-inch (2.5 cm) fill tube

 5-gallon (18.9 liters) bucket with handle  36-inch (1 meter) wooden ruler or dowel rod

 Replacement media (P/N M050)  3/4-inch (19-mm) socket with ratchet

Replenishment Procedure

The replenishment procedure is as follows:

Step 1

Turn Off the Water

A. Turn off the water to the appliance.

B. Open a tap to depressurize the appliance.

C. Close the tap.

Step 2

Remove Water From Media Tank

A. Use the 3/4-inch (19-mm) socket to

remove the fill plug from the media tank.

B. Insert the siphon hose into the fill port.

C. Siphon the water into the bucket until the

media level in the tank is reached.

Step 3

Calculate Amount of Media

to Replenish

A. Measure the freeboard distance from the

top of the tank to the media.

See Figure 10.

Note: The recommended freeboard

distance is 6.5 inches (16.5 cm).

B. Add 4.5 lb (2 kg) of media per inch below

6.5 inches (16.5 cm).

Example:

Measured freeboard 8.5 inches (22 cm)

Minus factory freeboard - 6.5 inches (16.5 cm)

Equals Adjusted freeboard 2.0 inches (5 cm)

Figure 10: Maximum Freeboard Amount

Replenishment equals approximately 4.5 lb (2 kg) of media x 2.0 inches (5 cm) (adjusted freeboard) = 9 lb (4 kg).
