Connect top outlet (1) to shower pipe with
proper fittings. Connect bottom outlet (2) to tub
spout pipe with proper fittings. Pipe (3) between

pipe in a straight drop no less than 8" (203 mm)
but no more than 18" (457 mm) long with only
one iron pipe or copper 90 degree elbow to the
tub spout nipple. Do not use PEX tubing for

Turn cartridge stem counter clockwise until it will
no longer rotate. Plug both outlets with proper
fittings. Check for leaks. After testing, remove
