WARNING
Risk of scalding!
This appliance may deliver water at high temperature.
▶ Refer to the plumbing code of Australia (PCA), local requirements
and installation instructions to determine if additional delivery
temperature control is required.
▶ This appliance is supplied with the CH control set at approximately
65 °C, a temperature that should be suitable for most installations
that comply with current Building Regulations. When the boiler
switches from CH to DHW, the temperature of the hot water may
2
briefly exceed the DHW set point if the CH temperature is set higher
than the DHW temperature. If the CH temperature is changed to
above 65 °C, it is advisable to fit a thermostatic mixing valve (TMV) at
the point of use (e.g. before the bath hot tap or shower) to protect
vulnerable people from scalding.
