elements contained in the tank body of the shower Mira Advance.

1.3. The showering temperature is adjusted by turning the temperature control knob,
which varies the flow of cold water across the elements. The slower the rate of
flow, the warmer the water and vice versa. The holes in the spray plate of the
shower handset should always be kept clean to maintain a consistent flow and
stable shower temperatures.

mains electrical voltage, will mean that the
flow rate of waterflow rate of water
flow rate of waterflow rate of water
flow rate of water at accustomed
'TEMPERATURE' control knob settings will vary as follows:
Summer: Due to the thermostatic response of the shower the flow from the
Advance on medium/high flow setting in the summer may be lower than the flow
in the autumn or spring.
Winter: Due to the thermostatic response of the shower the flow from the
Advance on low/medium flow setting in the winter may be higher than the flow
in the autumn or spring.
