THERMAL SHUT OFF
This is a safety feature for Thermostatic valves
manufactured to Australian Standard AS4032.4 - 2014
Basic terms, should the Cold or Hot water supply suddenly fail,
the mixing valve will shut off , preventing harm or
thermal shock.
This valve CT100 complies with Clauses 4.4.2 and 4.4.3 of the above standard.
Explanation as written in the standard AS4032.4 as follows;
Cold water isolation
When tested in accordance with Appendix D, the thermal shut - off under cold
water isolation of each thermostatic tap, when pre - adjusted to supply mixed
water at temperatures of 38
+/ -
2°C, 45
+/ -
2°C and the manufacturer ’ s nominated
maximum setting, shall not exceed the temperature rises and durations given in
Table 4.1 during both the period of shut - off of the cold water supply and
immediately following the restoration of the cold water supply.
The mixed water shall stabilize to within 2°C of the preset temperature, in not
more than 20.0 seconds following restoration of the cold water supply.
Heated water isolation
When tested in accordance with Appendix D, the thermal shut - off under heated
water isolation of each thermostatic tap, when pre - adjusted to supply mixed
water at temperatures of 38
+/ -
2°C, 45
+/ -
2C and the manufacturer ’ s nominated
maximum setting, shall not exceed the temperature rises and durations given in
Table 4.1. of the standard AS4032.4
The amount of water discharged following thermal shut - off under heated water
isolation of each thermostatic tap shall not exceed 0.75 L within 5 – 35 seconds
following heated water supply isolation.
The mixed water shall stabilize to within 2°C of the preset temperature, in not
more than 20.0 seconds following restoration of the heated water supply .
