SPECIFICATIONS
For Type 2 Valves, the supply conditions
specified in the TMV2 Requirements Manual
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 shower handset outlet.)
Note!
For gravity fed / other low pressure
systems (0.5 bar or below) do not fit the outlet
flow regulator.
•
For optimum performance supplies should be
nominally equal.
Flow Regulator Installation
Flow regulators are supplied with this product
and should be fitted in high pressure systems
to either;
•
Reduce excessive force and flow rate.
•
Reduce noise through the mixer due to high
or unequal pressures.
•
Stabilise incoming supply temperatures.
Temperatures
•
Factory Pre-set (Blend) Shower:
41°C
.
•
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).
