Proper Installation

Please read all instructions, specifications, and precautions before installing and using your water filter system.

This filter must be protected from freezing, which can cause cracking
of the filter and water leakage.

CAUTION

Precautions:
For cold water use only.

After prolonged periods of non-use (such as during a vacation), it is recommended that the system be flushed thoroughly. Let water run for
10 minutes before using.

The filter cartridges used with this system have a limited service life. Changes in taste, odor, and/or flow of the water being filtered indicate
that the cartridge should be replaced.

Do not install where system will be exposed to direct sunlight.
Your water filtration system will withstand up to 100 psi water pressure. If your house water supply pressure is higher than 100 psi, install a

pressure reducing valve before the system is installed.

Before You Begin

n Locate the main water supply line to your home and check to see what type of plumbing is in place (ex: plastic, copper, galvanized).

The main water supply line is typically located in a basement, crawlspace or garage. Connect to cold water line only.

n Measure the diameter of the existing pipe to determine what size fittings and/or valves (not included) will be required.
n Choose a location in the main supply line to install the Filter System. Make sure to place the Filter System in an area after the water

meter or pressure tank and before the water heater. Also select a location that will be easily accessible when changing filter cartridges.

n Consult your local plumbing codes and install accordingly.

STEP 3

Assemble the System

1 Dry assemble the complete system (according to the configuration chosen), including all fittings and valves.

OPTIONAL: If using a mounting bracket (not included), position it on the Filter System Head in alignment with the inlet and outlet ports.

2 Measure the overall length (see diagram) of the configured system.
3 Reduce this measurement enough to allow for the amount of engagement (X) to determine how much pipe to remove from the line.

STEP 4

Mark Measurements and Cut the Plumbing Pipe

CAUTION

Please wear safety glasses to protect eyes when cutting.

1 Mark the section of the plumbing pipe that will need to be removed (X) to allow for the configured system (as determined in Step 3).

NOTE: Measure twice, cut once!

2 Using a pipe cutter or hacksaw, cut the marked section from the plumbing pipe.

NOTE: Use a pan or bucket to catch any remaining water in the pipes.

3 Remove any burrs or debris from the cut edges with a file.

STEP 5

Hang the Filter System Head

1 Align the System Head A on the pipes so that the inlet and outlet are in the correct locations. The “in” port on the Filter System should

be facing the incoming water supply.

2 Allow the System Head to temporarily hang between the two cut plumbing pipes.
3 Apply plumber’s tape or appropriate sealant to the fittings and lines, according to your system configuration.
4 Make all connections and tighten fittings.

NOTE: Keep the Filter System in an upright position.

A grounding kit (not included) must be installed on water pipes if they are used to ground electrical systems, appliances or phones.

CAUTION

STEP 6

Install the Filter Housing

1 Insert the Filter Cartridge C over standpipe in the bottom of the Filter Housing A.
2 Screw the Filter Housing back onto the System Head and hand-tighten D.

IMPORTANT: Do not over tighten.
