POLISHING CARTRIDGE INSTALLATION
The Polishing Cartridge contains carbon that will offer a finished
taste to the drinking water. This is the last cartridge to filter the
water before the water flows from the newly-installed Chrome
Faucet.
WATER STORAGE TANK INSTALLATION
The Water Storage Tank included with your kit is more than meets
the eye. Inside the tank is a bladder made of a butyl rubber
designed for drinking water applications. Water will never touch
the actual metal tank as it enters and leaves the tank. To learn more
about the Tank, refer to the section on Unit Maintenance.
Step 2 – Choose a location that
is easy to access for when the
cartridge needs to be replaced
and secure the two clips to the
cabinet wall using the screws
provided.
Step 1 – Apply three rounds of
the plumbers tape to the nipple
on the top end of the Water
Storage Tank.
Step 2 – Thread the Pressure
Tank Valve onto the ¼” nipple
on the end of the Water Storage
Tank and hand tighten.
Step 1 – Apply three rounds
of the plumbers tape to the
¼” MPT x ¼” Press Fit Adapters
and then thread the Adapters
into the ends of the Polishing
Cartridge. Use an Adjustable
Wrench to tighten. Use caution
not to over-tighten the plastic.
