Temperature & ow adjustment
(Authorised Technicians Only)
The factory setting is 38°C. A maximum outlet temperature may be set between 30°C. And 43°C.
Water too hot
• If the water is too hot reduce the temperature on the appliance by turning the potentiometer
(g.10 p13) anticlockwise instead of mixing with cold water.
Any cold water added is not controlled by the electronic circuitry meaning that precise
temperature control can no longer be guaranteed.
• Note! Adding cold water wastes the energy used to heat it! This unit is not intended
for use with a ‘thermostatic mixing valve’ or tap.
