Installation
This valve is designed for either CC or IPS connections, depending on the discretion of the installer. If
using the IPS connections, thread sealing tape should be used liberally on all threads.
Connect the valve to the supply lines by either means desired. The hot supply should be on the left, the
cold supply on the right.
Connect the shower riser pipe to the top outlet and the tub drop pipe to the bottom outlet. Make all
connections firm and tight. Block and secure all pipes to the inside wall.
Flow Director
For water supply lines plummed ceiling to floor, please follow these instructions:
Hold the valve with the valve connections in the down position as illustrated below. Use a large flat blade screwdriver and
remove the flow director, located in the center port, as illustrated. After removing the flow director, turn the valve over so
that the valve connections are in the up position, and reinstall the flow director.
Now the casting can be turned over, with the valve connections facing the ceiling, to accept ceiling-to-valve water supplies.
Trim
MAKE SURE ALL WATER SUPPLIES ARE OFF
SHOWER: Assemble shower arm flange to the long end of shower arm. Put thread seal tape on the threads at both
ends of the shower arm. Screw shower arm into ell inside wall, do not install showerhead at this time. When a pipe
lookout nipple is used, put thread seal tape on the pipe thread and screw the tub diverter spout into the lookout
nipple. * CAUTION: spout is ABS plastic and will crack upon contact with some pipe thread compounds. We
recommend the use of thread seal tape. Pull out while turning so as not to scratch the wall. If a final turn by a
wrench is needed, use a small one with smooth jaws to grip spout end. Do NOT insert a tool into the spout end to
turn. You could damage the spout.
Flushing
IMPORTANT:
Pipe chips, sand, stones, and other solids found in new and renovated plumbing can damage the sealing
surface of the cartridge and cause a leak. To avoid damage, DO NOT TURN ON THE SUPPLY VALVES until
instructed below:
1. After installing and connecting your new faucet, install shower arm and tub spout, open both hot and cold cartridges.
2. Turn on both hot and cold water supply valves and allow the water to run from tub spout for 15 seconds.
3. Pull up on the diverter knob on the tub spout and run water through the shower riser for 15 seconds.
4. Turn off the hot and cold cartridges, install the showerhead and check the system for leaks.
