If you are unsure how electric showers work, please read through Section 10,
Operation before continuing.
1.1. Turn the Temperature control knob fully anticlockwise to the full cold position.
1.2. Turn on the water supply fully on at the isolating valve, check that water is
not leaking from the bottom of the case.
1.3. Switch on the electrical supply at the double pole switch. The 'Standby' neon
will provide a visual indication that the electrical supply is connected.
1.4. Press the 'Low' button. Check that water flows freely from the shower within
a few seconds. If not refer to Section 12, Fault Diagnosis. The water from
the handset will be at full force and at a cool temperature.
1.5. Turn the Temperature control knob slowly clockwise. As the knob is rotated
the flow will be reduced and the temperature will remain cool - this shows that
the flow regulator assembly is operating correctly. Return the Temperature
control knob anticlockwise to full cold position.
1.6. Press the 'Medium' button. The temperature of the water should rise slightly.
Allow a few seconds for the warm water to reach the handset - this shows that
the 'Medium' power setting is operating correctly.
1.7. Press the 'High' button. The temperature of the water will rise further - this
shows that the full power setting is operating correctly.
1.8. Set the shower temperature by rotating the Temperature control knob as
necessary. Turn the Temperature control knob clockwise for hotter water and
anticlockwise for cooler water.
Note! When the temperature is changed the flow rate will change.
1.9. When the required temperature is reached, push the STOP button to stop the
flow. Water will continue to flow from the handset for a few seconds, as water
is purged from the tank. Isolate the power at the double pole switch.
Note! A slight hissing sound may be heard from the Mira Sport during
operation. High mains water pressure and high shower temperatures will
affect the tone. This is quite normal in use.
