INSTALLATION GUIDE
Connections on the built-in mixer body are
¾" BSP (female) and are marked “hot in”, “cold
in” and “mixed out” on the body casting. There
are two mixed outlet ports, one of which must be
plugged with the blanking plug supplied. For
maximum flow performance the unplugged out-
let should be connected to the wall elbow or the
fixed overhead shower using 22mm copper. The
¾"/22mm connectors must be jointed to the valve
body using jointing compounds or PTFE tape.
Under no circumstances should soldered joints be
used near the valve body as this will damage the
fitting. It is recommended that isolation valves
be fitted upstream of the valve body.
TREVI THERM A3000
The valve is supplied as per position 1 (Figure 8)
with options for installation in positions 2, 3 & 4.
Should positions 2, 3 or 4 be required then the
temperature adjustment carrier will need to be
repositioned so that the triangular raised mark at
the rear is positioned at the top. The front handle
carrier is rotated if necessary until the triangular
indent is again at the top. The handle can then be
pushed into position with the override button to
the top.
TREVI OUTLINE THERMOSTAT A3700
This valve is supplied as per position 3. Since the
wall plate is designed to be mounted vertically,
position 4 is the only alternative orientation
advised.
