Before You Begin
CAUTION: Risk of property damage. Before finishing the
wall, make sure the supply lines are connected to the mixer
valve with the cold line plumbed on the left and the hot line
plumbed on the right.

document show installation for a handle located to the right of the
spout. The valve is designed for handle installation on the right.
Special steps will need to be performed to position the handle to the
left of the valve.
