INSTALLATION INSTRUCTIONS
WARNING: Failure to follow these instructions could
prevent the mixer/transfer valve from functioning
properly.
1. Shut OFF water supplies.
2. Install the body (1) so the surface of the fi nished
wall is fl ush with the front of the plasterguard (2).
The plasterguard is
mounted on the body
using the two stringer
mounting holes (3) on
the bracket. NOTE:
Remove cover (4) to
access body mount-
ing holes. Ensure the
word "UP" (5) is on top
of the valve body when
installing.
3. Install transfer valve
so that the transfer valve inlet connects to the top port
of the mixer valve. See below. The transfer valve must
be located at least 4-15/16" (center to center) away from
the mixer valve. A left-hand thread to sweat adaptor
and gasket are required for this connection. Use a 1/2"
copper pipe size, a taper to sweat adaptor, and a female
thread to sweat adaptor to fi nish the connections from
transfer valve to mixer valve. Copper pipe and adaptors
not provided.
Connect hot and cold supply lines to left and right inlets of
mixer body. Left is hot and right is cold (as viewed from
front). Threaded inlets are 1/2" NPT (iron pipe size). Use
an approved thread sealant for threaded connections.
Remove bonnet (1) and test cap (2) before soldering.
Leave screen (3) installed. WARNING: Avoid soldering
at high temperature. Exposure to high temperatures
may damage screen.
4. Rotate the cartridge (1) so the words “hot side” (2)
appear on the left. Insert cartridge into valve body as
shown. Make sure the cartridge tubes and o-rings (3)
are properly seated in holes at the base of the body.
Ensure the keys on the body are fully engaged with the
slots in the body (4).

plumbing from top
outlet of transfer valve

NOT install the shower
head onto arm at this
