WARNING: This system/device must be set by the installer to ensure safe, maximum temperature. Any change in
the setting may raise the discharge temperature above the limit considered safe and may lead to scalds.
CAUTION: As the installer of this valve, it is your responsibility to properly install and adjust this valve per the
instructions given. This valve does not automatically adjust for inlet temperature changes, therefore, it is necessary
to adjust the Rotational Limit Stop at the time of installation. You must inform the owner/user of this requirement by
following the instructions below. After installation and adjustment, you must write in the temperature and the date
you adjusted the Rotational Limit Stop on the warning label provided and apply or attach it to the hot water heater.
Be sure this instruction sheet is delivered to the owner/user.
WARNING: This pressure balanced bath valve is designed to minimize the effects of outlet water temperature
changes due to inlet pressure changes, commonly caused by dishwashers, washing machines, toilets and the like.
It may not provide protection from scalding when there is a failure of other temperature controlling devices elsewhere
in the plumbing system if the Rotational Limit Stop is not properly set, or if the hot water temperature is changed after
the Rotational Limit Stop is set, or if the water inlet temperature changes due to seasonal changes.
INSTALLER: LEAVE THIS INSTRUCTION MANUAL FOR OWNER'S/USER'S REFERENCE

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 mounting 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).
For s howe r h ead
installation connect
plumbing from top
outlet of transfer valve
to shower head arm
with proper fi ttings. Do
