Introduction
Thank you for your purchase of a Watts Pure H2O Whole House
Water Filter. Water quality concerns are quickly becoming more of a
focus for the public. This Watts Pure H2O whole house water filter
has been designed and tested to provide you with a higher quality
of water.
This filter is designed to reduce the amount of sediment that would
normally enter your home water system. Reducing the amount of
sediment in your home water system will allow your fixtures and
water use appliances to work better.
It is important to change out your filters at the recommended inter-
vals as indicated in this system manual. When replacing the filter
elements, pay special attention to any cleaning instructions. Should

Prior To Installation
Watts Pure H2O’s Whole house filter is designed to be installed on
the main waterline servicing the house. It should be installed indoors
where it is not subject to cold temperatures or long term exposure
to direct sunlight. Watts Pure H2O does not take any responsibility
for the plumbing of the system into the water line. All water filtration
systems must be installed in accordance with local plumbing codes
and regulations.
Note: For installation, you will need to purchase fittings based on
the pipe size and material of the incoming water line that you will be
tapping into.
Whole House Filter Installation
Step 1 -
Determine placement of the unit. Make sure the installation
location allows for easy servicing of the system, including a
clearance beneath the filter bowl for filter changes.
Step 2 –
Shut off main water supply and open a faucet beyond the
connection to relieve water pressure. Then close the faucet
when depressurized.
Step 3 –
Make sure water flow direction coincides with the “IN” and
“OUT” ports marked on the unit.
Step 4 –
Cut the water line where the Whole House Filter is to be
installed. The amount of pipe to be removed will be depen-
dent on the type of fittings used. Copper pipes need to be
cleaned & de-burred of any imperfections.
Step 5 –
Using the fittings previously purchased, make sure that the
flow direction is correct through the filter system and plumb
the system to the waterline.
For copper pipes we recommend using brass 3/4" MPT
x plumbing size (1/2" or 3/4") compression style fittings.
For all other material types, check with your plumbing
professional.
Make sure not to overtighten threaded port to the unit!
CAUTION
Operational Paramaters
NOTICE
This unit must be installed vertically with the lid on top.
NOTICE
If pipes will be sweat soldered, do not connect into the unit
until the pipes have cooled. Make sure to use Teflon tape on
all male pipe threading used.
