INSTALLATION
Unscrew the aerator from the end of your faucet to reveal the thread connections and check to
confirm whether this connection is male or female. Your diverter valve comes with a standard
3/8” female thread connection and will connect directly to a 3/8” male faucet connection. If
you have a 3/8” female faucet connection, then you will need to use the universal adapter that
has een provided as part of your Permaflo Purity connection kit.
Lu ricate the new diverter valve with vegeta le oil. Pour a drop of oil into the top of the valve
in the hole and then work the stem ack and forth.
Note: This procedure should be done every few months to keep the valve lubricated internally.
Using finger pressure only, screw the diverter valve onto the faucet threads. The threads are
easily damaged so e careful to prevent cross threading.
If you cannot thread it on by hand, then something is wrong. Stop and investigate.
Once the valve is screwed on finger tight, a pair of pliers can then e used to snug it up. It does
not require a large force. Position the hose so that it does not interfere with the sink efore the
final tightening. You can use elastic ands to hold the hose tight to the faucet so that it remains
out of the way.
Unscrew the countertop housing top. Remove the u le wrap packaging from the ceramic
cartridge. If the ceramic is not already installed, inspect the new ceramic for any damage or
cracks. Make sure the lack o-ring is in place. Gently thread the ceramic into the ase of the
housing until it is snugly seated. Extensive force is not required and no tools should e used.
Carefully replace the top over the ceramic and thread it into the ase. Again, hand tight is all
that is required.
Place the complete unit into the sink. Turn on the cold water slightly so that it flows through
the diverter valve into the sink. Inspect for leaks around the diverter valve faucet connection
and the aerator connection. Turn on the diverter valve stem (sending water to the filter
housing) and again inspect for any leaks from the diverter valve connections or the sump o-ring.
Note: If a leak is observed, simply turn off the cold water tap, wait for the pressure to drop and
then snug up the leaking connection as required.
Increase the water pressure and again o serve for leaks for at least two minutes. While
o serving, rotate the filter unit onto each side so that the top of the sump is held lower than
the ase. This will allow excess air to escape from inside the unit ena ling it to work more
efficiently. Allow the water to run to waste for five minutes.
