If you are unsure how electric showers work, please read through, Section 10, Operation
before continuing.
1.1. Make sure that the START/STOP button is in the
outermost position and that the electrical supply has
been isolated.
1.2. Turn the BOTTOM control knob fully anticlockwise to
the full cold position.
1.3. Turn the water supply fully on at the isolating valve,
check that water is not leaking from the bottom of the
case.
1.4. Turn the TOP control knob to the low position.
1.5. Switch on the electrical supply at the double pole
switch. The 'POWER' neon will provide a visual
indication that the electrical supply is connected.
1.6. Press the START button. Check that water flows
freely from the shower within a few seconds. If not
refer to Section 11, Maintenance. The water from the
handset will be at full force and at a cool temperature.
1.7. Turn the BOTTOM 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
knob anticlockwise to full cold position.
