Before You Begin
IMPORTANT! Risk of product damage. Do not apply direct heat to the transfer valve body. Excessive heat will damage the plastic valve components and plaster guard.
Observe all local plumbing and building codes.
Do not remove the plaster guard from the transfer valve until instructed to do so.
A mixed water supply is required for this transfer valve.
If less than three accessories will be installed, do not plug any outlets on this transfer valve without completing the two-way conversion. The transfer valve is not intended to be used as a shut-off valve.

Three-Way Valve Installation
NOTE: When the valve is converted to two way operation, handle rotation is limited to 120 degrees. The plug at the center connects the left and right hand ports allowing either port to be used for an additional accessory.
Install 1/2″ copper tubing or 1/2″ piping for all accessories. Securely fasten the piping and outlet ells to the framing.
Install temporary 1/2″ nipples in the outlet ells so they extend a minimum of 2″ (5.1 cm) beyond the finished wall.
Turn on the water supply to the transfer valve and check the transfer valve for proper operation and leakage. Once everything is verified, turn off the water.
Install caps on the temporary bath and shower nipples. Turn on the water and check for leaks. Once no leakage is verified, turn off the water.
