NOTE: “Front” on the base (a) must
face the front of the sink. The two
mounting plates (b) on the base (a)
must be loose and movable during the
installation of the base (a).
Step 1a: Installing the easy install assembly (without escutcheon)
Shut off the water supply. Remove the
old faucet. Clean the mounting surface.
Check for the proper thickness of the
sink. Insert the base (a) into the sink. If
your model does have a escutcheon,
skip to step 1 b.
Step 1b: Installing the easy install assembly (with escutcheon)
Place the escutcheon (C) and the
gasket (D) on the sink. Insert the base
(a) into the escutcheon (C). NOTE:
“Front” on the base (a) must face the
front of the sink. The two mounting
plates (b) on the base (a) must be
loose and movable during the
installation of the base (a). If the sink
is uneven, use silicone under the
gasket (D).

Fig 1 Fig 2
Press the base (a) and escutcheon (C) so that they can not move, then turn the screws
with the provided hex wrench (M, HEX: 6.0mm) clockwise, as shown Fig 1. When the
mounting plates (b) make contact with the sink (1), continue to turn the screw with the
provided hex wrench (M, HEX: 6.0mm) clockwise, as shown Fig 2, until the base (a) is
completely tightened and secured, as shown Fig.4.

to ensure proper installation. Ensure
they are tightly connected by firmly
pushing together. Secure the
connection by hand tightening the nut
(3) in a clockwise direction onto the
threaded sensor cable.

To open the battery housing, squeeze
the tabs (1) on the cover (2), then

on the battery (3) to the (+) and (-)
markings in the battery pack (4). The

always connect to the spring end of
the battery slots in the battery pack (4).
