Exposed Thermostatic Valve
U

Introduction
Installation notes
This exposed valve is suitable for use with all water systems up to a
maximum operating pressure of 72 psi and static pressure of 144 psi,
beyond which pressure
-
reducing valves must be
installed
. The
minimum water pressure requirement is 14.5 psi.
The outlet is controlled by a flow control cartridge, commonly used for
a main shower head.

in dimensions
Tools required
The installation must comply with all plumbing codes including local
codes. This valve is a mixing device and therefore requires the water
supplies to be reasonably balanced, otherwise we recommend a
pressure
-
reducing valve to be
installed
.
The valve is fitted with integral single
-
check valve cartridges,
therefore the exposed valve is protected against cross-flow due to
unbalanced line pressures.
Installing shut-off valves on incoming supply lines is recommended
for ease of maintenance.
I
MPORTANT
:
T
urn off the main water supply before connecting
to any existing pipework.
WARNING! Please check for any hidden pipes and cables, electric
or otherwise
,
before drilling holes in a wall
or floor.
