Troubleshooting Guide

Water Leaks at Threaded Fittings: Tighten slightly more until leak stops. Water leaks at Push-in Connections Push tubing in as far as it will go.If leaking continues, shut off

water at the original valve and remove water line by pushing in on the connector collar while pulling the tubing away. (See Push-in Fittings Section) Inspect tubing for cracks and scratches.If tubing is cracked or scratched, simply cut that portion away and reinsert tubing into fitting.

Make sure tubing is cut straight.If not, recut.

Installation Instructions

For Use With Cold Water Only NOTE: Remove items from under the sink. Place a catch basin

there to collect small amounts of water that may run out when disconnecting water supply lines.

1.Turn off cold water supply valve and remove existing fitting and/or tubing from cold water side of faucet.

2. Loosely assemble sump to filter head and attach filter bracket. Use this assembly to mark a location under the sink that is not in the way but allows for easy access to change filter. Allow room to operate housing wrench and a minimum of 2 1/2” clear space below the unit to facilitate changing cartridge. Once this is done disassemble components for installation.

3. Determine length of tubing required from filter head/bracket to faucet and from water supply line to filter head/bracket by holding tubing in place ensuring it is of appropriate length. Do not kink tubing as this will impede water flow. If necessary, loop tubing around to avoid it being kinked.

Cut tubing straight with a utility knife or tube cutter (for copper piping). (See Figure 1.)

4. Install faucet adapter fitting to faucet (see Figure 2). Do not overtighten to prevent damage to fitting. Referring to section “Using Push-In Fittings”, insert a section of plastic tubing into fitting, making sure end of tubing is firmly seated to backstop.

5. Onto one end of the remaining section of tubing, slide the compression hex nut and ferrule onto the tubing and put in the tube insert (see Figure 3). Fasten this assembly onto 3/8”water supply outlet. Do not overtighten (see Figure 4). Overtightening will cause tubing to separate from fitting.

• Install away from direct sunlight as prolonged exposure to light can weaken plastic components.

• Some local codes may require the use of a licensed plumber or certified installer when disrupting a potable water line. Determine and follow any and all local codes and requirements.
