Cartridge Replacement Instructions

CAUTION

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

•The disposable filter cartridge MUST be replaced every 6 months or at the rated capacity or if a noticeable reduction in flow rate occurs.

1.Turn off incoming water supply.

IMPORTANT NOTES

•For those systems with internal shut-off valves, turn the valve on the filter head to “OFF” position.

•For those systems with external shut-off valves, depress the pressure relief button on top of filter head to relieve pres- sure in filter.

2.Unscrew sump from filter head. Empty water from sump and dispose of spent cartridge.

3.Clean and inspect all components, including the o-ring seal. Lubricate o-ring seals with a light coating of food grade lubricant. Replace o-ring if there is visible damage.

4.Install new cartridge(s) into sump (over center post in a two high unit).

5.Screw sump into head until sump becomes snug and cartridge is sealed. HAND TIGHT IS SUFFICIENT. The use of a wrench for tightening is not recommended and may result in damage.

6.Turn on incoming water supply.

IMPORTANT NOTES

•For those systems with internal shut-off valves, turn handle to “ON” position. Wait until the filter is filled with water and check for leaks. Open and close the valve once to release trapped air.

•For those systems with external shut-off valves, depress pressure relief button on filter head until air is purged from system.

•Flush new cartridge for 5 minutes prior to service.

•Replace cartridge when there is a decided drop in water flow at faucet or tap or line pressure downstream of filter system drops below 20 psi (138 kPa). Do not leave valve in the “OFF” position for an extended period of time or use as a substitute for main water line valve.
