10 1300905-W2-A
Temperature
Minimum Cold Water Temperature: 1°C
Maximum Hot Water Temperature: 70°C*
Factory Preset:
43°C
under ideal installation conditions
Optimum Thermostatic Control Range:
35°C - 46°C
*Note! For optimum performance reasons it is recommended that the maximum hot water
temperature is limited to 65°C.
Caution!
During thermal disinfection the mixing valve can operate up to
85°C
for short
periods. Ensure safety precautions are followed during discharge. Chemical disinfection
agents e.g.chlorine/chloramines combined with higher temperatures will affect the life of the
product adversely and could detrimentally affect the thermostatic performance.
Flow Rates
Minimum Flow Rate:
6 l/min
at mid blend with nominally equal supply pressures.
Maximum Flow Rate: 120 l/min
Flow Control
Rada 320 mixing valves do not have integral flow control; appropriate provision must be made
for this in the outlet pipework. This can be in the form of a stop-cock, mechanical timed-flow
controller, solenoid or basin/bath tap. The device chosen must be non-concussive in operation.
Connections
320 IC

320 IF - Inlets & outlet connections: 1” BSP female thread.
320 F - Inlet & outlet adaptors 1” BSP female thread.
320 M - Inlet & outlet adaptors 3/4” BSP male thread .
