Operating Parameters
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 shower handset outlet).
Note!
For gravity fed / other low pressure systems (0.5 bar or below) do not fit the
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.
Important! The fitting of flow regulators will invalidate any TMV2 compliance
due to minimum flow rate requirements. Do not fit the flow regulator in TMV2.
applications.
Temperatures
• Factory Pre-set (Blend) Shower:
43°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
.
