INSTALLATION GUIDELINES
Page 2 of 3 6.13.2014
These guidelines have been prepared for the professional contractor to aid in the installation of:
UNIVERSAL 1/2" THERMOSTATIC VALVE STYLE NO. GUTH56, GU56TH (UK)
All dimensions are based on original specification and are subject to change and variation.
Please consult your Design Associate for current specifications.
7. The bottom port of the valve body is not plugged
and can be used to supply water to other fittings.
Install a 1/2" NPT plug (not supplied) if the port will
not be used.
8. Install the TILE GUARD to protect the valve during
the completion of the finished wall and to create the
exact opening for access to the service stops and
future servicing.

INSPECT THE INSTALLATION:
9. Remove TILE GUARD and turn on water supply and
inspect all connections for leaks.
10. Turn off the water supply and turn off the SERVICE
STOPS, seen in Figure-02.
11. Reinstall TILE GUARD.
TEMPERATURE CALIBRATION:
¾ The risk of scalding exists until the installer has
properly calibrated/adjusted the temperature
setting prior to final trim installation.
12. Remove the TILE GUARD and THREADED TUBE.
Slide the O-RING and LIMIT STOP up the
CARTRIDGE STEM. DO NOT REMOVE OR DAMAGE
THE O-RING. See Figure - 05.

4. Run 1/2" (15mm) copper supply lines to the proper
height of the valve inlets and be sure to secure all
piping and fittings.
¾ Note: The valve body has 4 mounting tabs; 2 of
these tabs are used to hold the tile guard to the
valve body and the other 2 can be used to secure
the valve body to adequate blocking.
5. DO NOT APPLY DIRECT HEAT TO THE VALVE. Pre-
solder 1/2" male NPT adapters (not supplied) prior
to threading into the valve body.
6. For each fitting that will have water flowing to it,
install a wall valve or diverter valve (both sold
separately) at the same rough in depth and
according to the flow direction arrow marked on the
wall valve or diverter valve body.
