Important Information
WARNING: Risk of personal injury. Do not use the bath
filler as a grab bar or support bar when entering or exiting
the bath. The bath filler is not designed to support weight.
NOTICE: To avoid damage to the O-rings on the bottom of the
faucet, keep the faucet vertical and use care when installing the
faucet.
Observe all local plumbing and building codes.
Shut off the main water supply.
A drill bit is provided for installation to wood support. A
different drill bit is required for concrete floor installations; this
bit is not provided.
The dimensions given assume the spout and bath are mounted on
the same surface. Adjust the dimensions accordingly if the spout
and bath are mounted on different surfaces.
If this product is installed with an overflowing bath, the outer rim
of the bath should slightly overlap the 2x4 framing.
Installer supplied copper tubing must be 5/8″OD (1/2″
Nominal).
Carefully review this document and any appropriate rough-in
sheets. Design the bath enclosure accordingly.

1. Spout Orientation
When performing this installation:
Verify correct spout orientation before securing the base to the
floor.
Connect the faucet to the base with screws and washers through
the flange. Orient the spout to the inside of the bath.
Rotate the base if necessary by loosening the screws to verify the
supplies are in line with the base inlet connections. You may have
to modify the supply lines if necessary.
The cold supply should be connected where the blue mark or the
notch is located.
Test the handle to verify full rotation will not interfere with the
bathing fixture or the back wall.
