FILTER REPLACEMENT INSTRUCTIONS

To reduce the risk associated with property damage due to water leakage:

• The disposable replacement ﬁ lter must be replaced every six months or sooner if a noticeable reduction in ﬂ ow

rate occurs.

Note: Refer to Figure 1 and visually inspect your system for the following instructions.

1. Turn valve handle to "OFF" position. The inlet and outlet lines are now closed off from the filter assembly and the

pressure has been released at the built-in vent port.

2. Unscrew sump to the left (counterclockwise) from the filter head using provided filter wrench if necessary, remove

filter and empty water from sump.

3. Clean and inspect all components. Ensure that the o-ring is seated into the sump groove, moisten o-ring with

water. Replace o-ring if there is visible damage.

4. Install new replacement filter into sump, making sure that it is centered and seated.

5. Screw sump with o-ring to the right firmly onto head until a definite stop is felt and replacement filter is sealed.

Hand tight is sufficient. However, be sure not to overtighten or force sump.

6. Turn valve hand to the "ON" Position. Wait until filter system is filled with water and check for leaks. Open and close

the valve once to released trapped air. Allow a slight pause in the "OFF" position. Change filter when there is a

decided drop in water flow at the faucet or tap.

To reduce the risk associated with property damage due to water leakage:

• DO NOT leave valve-in-head models in "OFF" position for an extended period of time or use as a substitute for main water

line valve if line must be shut off for servicing.
