Faucet Installation
Gather and identify the faucet pieces.
Step A - Remove faucet base and faucet spout from their respective
plastic bags . From above the sink, feed the faucet tubing
& toggle bolt down through the 1¼" mounting hole in the
sink . Ensure that the soft rubber gasket has the protec-
tive white paper removed from both sides and is uniformly
positioned in between the base of the faucet and the top of
the sink .
Step B - Align the faucet base so that the handle is on the right side
and the base is sitting flush on the sink top . Using a phillips
head screwdriver, turn the screw located down the hole
where the spout will be installed, clockwise until the toggle
bolt secures the faucet base snug onto the sink top .
Step C - Once the faucet base is securely fastened to the sink top,
insert the faucet spout into the faucet base until it is fully
seated . Turn the handle up (away from you) to the “OFF”
position .
Step D - Connect the loose end of the
