WARNING
!
Please read carefully before proceeding with
installation. Your failure to follow any attached
instructions or operating parameters may lead to the
product’s failure.
Keep this Manual for future reference.
WARNING
!
Do not use with water that is microbiologically unsafe or of
unknown quality without adequate disinfection before or
after the system.
If you are unsure about installing your WATTS water filter, con-
tact a WATTS representative or consult a professional plumber.
Test the water periodically to verify that the system is per-
forming satisfactorily. Discard small parts remaining after
the installation.
Failure to install the system correctly voids the warranty.
Handle all components of the system with care. Do not drop,
drag or turn components upside down.
Be sure the floor under the water filter system is clean, level
and strong enough to support the unit.
