Assembly of Outlet Connections
There are 3 outlets of the transfer valve, providing 3 separate, discrete functions.
Suggested outlet designations are as follows:
• Outlet #1: Handshower
• Outlet #2: Showerhead
• Outlet #3: Tub Spout, Additional Showerhead, or Handshower
NOTE: Do not block any outlet. If any outlets are not to be used (i.e. tub spout), the outlet should
be plumbed into the line of one of the other outlets. This valve is not intended to be used as
a shut-off valve. Damage to the shower system may result if the valve is used as a shut-off
valve. To prevent the potential of cross flow, check valves must be integral to the supply
valve or installed in both hot and cold water supply lines.
Rough-in Body Casting
1. The distance from the supply valve center to the center of the transfer valve must be a minimum of 12"
(305mm) to assure proper clearance of the transfer valve escutcheon and supply valve escutcheon.
2. In the finished wall, make a minimum hole of 2-1/2" (64mm) diameter for the transfer valve installation.
FINISHED
3. The plaster ground is used as a guide to help install the valve at the proper depth within the wall. The
WALL
plaster ground should be flush with the finished wall once the transfer valve is installed. The inlet of the
transfer valve may not be aligned with the outlet of the shower valve. For example, the transfer valve
installed with Posi-Temp has an offset as shown in the Figure at left.

5. With the valve castings "IN" port facing
directly down, connect the outlet of the
main supply valve to the inlet of the
transfer valve using a 1/2" copper water
tube. If the supply valve has 2 outlets, one
of these outlets must be plugged.
CAUTION:
For all installations, the cartridge must
be removed from the valve body before
heating the valve. Failure to do so will
result in cartridge damage. Please refer
to the instructions 'Removing Cartridge for
CC Connection/Servicing.'
