SPECIFICATIONS
For Type 2 Valves, the supply conditions specified
in section:
‘Type 2 Valves - Application’
take
precedence over the operating parameters which
follow.
Pressures
•
Max Static Pressure:
10 Bar
.
•
Max Maintained Pressure:
5 Bar
.
•
Min Maintained Pressure (Gravity System):
0.1 Bar
(0.1 bar = 1 Metre head from cold
tank base to showerhead outlet).
•
Note!
For gravity fed or other low pressure
systems (0.5 bar or below) do not fit the
outlet flow regulator.
•
For optimum performance supplies should
be nominally equal.
Temperatures
• Factory Pre-set (Blend) Shower:
41°C
.
• Note! Due to variations in site conditions
the maximum temperature may need
adjustment.
• Temperature Overide set at
5°C
below Factory
Preset.
• Optimum Thermostatic Control Range:
35°C
to 43°C
(achieved with supplies of 15°C cold,
65°C hot and nominally equal pressures).
• Recommended Hot Supply:
60°C to 65°C
Note!
The mixing valve can operate at
higher temperatures for short periods without
damage, however this could detrimentally
affect thermostatic performance. For safety
and performance reasons it is recommended
that the maximum hot water temperature is
limited to 65°C.
• Cold Water Range: up to
25°C
.
• Minimum Recommended Differential between
Hot Supply and Outlet Temperature:
12°C
.
Thermostatic Shut-down
• For safety and comfort the thermostat will
shut off the mixing valve
within 2 Seconds
if
either supply fails (achieved only if the blend
temperature has a minimum differential of
12°C from either supply temperature).
Connections
• Inlets: 15 mm Compression.
• Outlet: ½” BSP Flat Face / 15 mm
Compression
• Standard connections are:
hot - left, cold -
right, outlet - bottom (EV models), top (BIV
and BIR models)
.
