1. Install the Faucet

IMPORTANT! If you are mounting the faucet to an uneven surface
(such as tile grout lines), apply a suitable sealant in addition to the
O-rings provided. Do not use petroleum based sealant.

Insert the O-ring into groove of each escutcheon.
Slide an escutcheon over each of the threaded shanks.
Position the faucet through the mounting surface.

NOTE: The handles will rotate toward the user when properly
installed.

Partially thread two screws into the threaded ring until the
screws barely protrude from the backside of the threaded ring.

Slide a metal washer onto each threaded shank from underneath
the mounting surface.

Thread the threaded ring onto the shank until the threaded ring
is about 1/4″ (6 mm) away from the underside of the mounting
surface.

Turn the threaded ring so the screws are to the front and back.

2. Install the Supplies

CAUTION: Risk of restricted waterflow and product
damage. Use extreme care to avoid kinking and twisting the

supply hoses. The supply hoses must not be taut after
installation.

NOTE: If the sink installation requires that you coil the supply hoses
to obtain a good connection, maintain an inside coil diameter of at
least 3″ (7.6 cm).

Carefully position the hot and cold water supplies so they will
not interfere with other hoses or items below the mounting
surface.

Connect the supply hoses to the supply stops. Left is hot, right is
cold.

Tighten all connections.
