See Roughing-in Drawing on cover page. The port with the BATH TUB picture is the high flow.
The DIVERTER can be installed with the inlet rotated in any position.
Supply connections are 1/2" NPT connections.
For proper positioning the finished wall must be within side of PLASTER GUARD.
Connect water to valve. The reverse side of the body is marked with arrows.
CAUTION: Do not solder near the VALVE. Damage to the SEAL may occur.
Do not seal any outlets. The DIVERTER cannot be used as a stop valve.
For support use pipe braces secured to wooden braces. 
Check that the DIVERTER operates correctly and does not leak.
To do this, screw off the PLASTER GUARD, turn around, and
insert using the fluted pin into the fluting on the DIVERTER SPINDLE
and use as a diverter knob. Screw the PLASTER GUARD back on.
Have the wall tiled only with the PLASTER GUARD screwed on.
