Installation
Attach The Filter To Your Faucet
Position the filter system so that the unit is on the left side of your faucet and the
Filter Monitor is facing you. Attach the threaded mounting nut to the faucet and
turn until hand tight.
The filter assembly may be moved back and forth while holding the mounting nut
to help tighten the faucet mount.

Installation
Determine The Need For An Adapter
If there are threads on the outside of the faucet – Proceed to Step 3.
If there are threads on the inside of the faucet:
Select the adapter and washer that fit your faucet. Place the washer into the
recessed end of the adapter. Apply plumbing tape (provided) to the threads on
both ends of the adapter. The tape acts as an extra seal and strengthens the
connection. Screw the adapter into the faucet. Hand tighten. A coin may be
inserted into the notch in the bottom of the adapter to help tighten it by an
additional 1/2 turn.

Flush The Filter
The Water Selector Switch is located on the far right end of the filter unit. Turn
the Water Selector Switch to the vertical position. Turn on the cold water tap
and allow water to run through the filter until the meter changes from “Flh” to
“ooo”. Do not drink or use the filtered water during the flush cycle.
This flush will remove any carbon particles and activate the filter for use. It is
normal to see some carbon particles rinsed from the filter during the initial flush.
The flush does not affect the cartridge life. The
cartridge included with this system is good for up
to 200 gallons of water, and the gallons used are
only measured after the filter has been activated.
Please refer to the Replacement Cartridge section
for expected life of your filter and contaminant
reductions.
