MOUNTING BRACKET TO CABINET WALL

The bracket can be used as a template for marking the location of the mounting

screws. When determining the location of the bracket make sure you leave 1-1⁄2²

to 2² of free area under the sumps to allow for sump removal and enough space on

either side to make the tubing connections.

MAKE TUBING CONNECTIONS

1. Run the length of 3⁄8² tubing, connected to the bottom of faucet, to the filter

system outlet, Fig.1 on page 2. Allow enough slack in the tubing to be able to

place the system on the floor in front of the sink. Measure and cut the end of

the tubing square.

2. Slide a compression nut onto the end of the tubing and push a tubing insert

into the tubing.

3. Connect the tubing and tighten the compression nuts securely.

4. Repeat the preceding steps to connect a length of tubing between the filter

system inlet and the water supply/saddle valve, Fig. 1 on page 2.

BATTERY PACK INSTALLATION AND CONNECTION

1. In a dry location, within reach of the electronic base 3¢ leadwire, select a place for

the battery pack (see Fig. 1 on page 2). The battery pack attaches to most surfaces,

using the included “sticky-back” Velcro™ strip.

2. The battery pack uses two size “AA” batteries. Check to be sure they are

installed correctly. Then, remove the paper backing on the Velcro™ strip and

secure the pack in place.

3. Fasten electronic base leadwire and battery pack connector together.

FILTER CARTRIDGE INSTALLATION OR REPLACEMENT

CAUTION: Never remove sumps with water pressure in the

filtration system.

1. Close the water supply/saddle valve (Fig. 1 and 2A) to the filter. Press the vent

valve on the top of the Filter I head to relieve pressure in the system, Fig. 5, or

open the filtered water faucet.

2. Turn the sump off of the filter head as shown (use the sump wrench provided).

Be careful, the sump is full of water. Locate and save the large o-ring seal.

Remove and discard the used filter cartridge.

3. Be sure the inside of the sump is clean. Thoroughly wash with hot, soapy water

and rinse.

4. Remove the wrapper and labels from the new filter cartridge and insert the

filter cartridge in the sump. Some cartridges fit either

way, while others fit only one way. Observe markings on the end of the cartridge. The sediment/taste and odor filter cartridge should

always be placed in the Filter I location.

5. Lightly lubricate the o-ring seal, in the sump, with clean silicone grease. Be sure it is fully seated in its groove.

6. Hold the sump up to the filter head, aligning the center hole in the cartridge with the protrusion on the bottom of the head.

NOTE: If the sump will not tighten up to the head, you may have the cartridge in upside down. Take the cartridge out and check the

markings on the end of the cartridge for correct orientation.

7. Being careful not to cross-thread, turn the sump onto the filter head and hand tighten securely (see Fig.4).

8. Repeat steps 2 through 7 for the other filter.

9. Open the filtered water faucet. Then, slowly open the water supply/saddle valve and allow the filter housing to fill. While it is filling,

press the filter vent valve to release air in the filter.

10. Close the filtered water faucet. Then, check for leaks between the sump and the head.

NOTE: If leaking, turn off the water supply and open the filtered water faucet, or press the vent valve to depressurize the filter. Then,

disassemble the filter and check the o-ring for cuts, flat spots, etc., and sealing surfaces for foreign material. Clean the o-ring and lubricate

with clean silicone grease. Carefully press into the groove in the sump.

11. Remove and install two new “AA” alkaline batteries in the battery pack. Removing the batteries or momentarily disconnecting the

leadwires resets the six month electronic base timer.

12. The filter cartridges contain activated carbon, a black powder. When new, open the filtered water faucet for ten minutes to allow

fine, harmless carbon particles to purge from the cartridge. Air suspended in the water may also cause a “cloudy” appearance. This

air is harmless and should dissipate quickly.
