If you are unsure how electric showers work, please read through the
Operation
section before continuing.
1.
Make sure that the
TOP
control knob is in the
'STOP'
position and that the
electrical supply has been isolated.
2.
Turn the
BOTTOM
control knob fully anticlockwise to the full cold position.
3.
Turn the water supply fully on at the isolating valve, check that water is not
leaking from the bottom of the case.
4.
Switch on the electrical supply at the double pole switch.
5.
Turn the
TOP
control knob to the
'LOW'
position. Check that water flows freely
from the shower within a few seconds. If not, refer to the
Maintenance
section.
The water from the handset will be at full force and at a cool temperature.
6.
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.
7.
Turn the
TOP
knob to the
'MEDIUM'
position. 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.
8.
Turn the
TOP
knob to the
'HIGH'
position. The temperature of the water will rise
further - this shows that the full power setting is operating correctly.
9.
Set the shower temperature by rotating the
BOTTOM
knob as necessary. Turn
the knob clockwise for hotter water and anticlockwise for cooler water.
Note!
When the temperature is changed the flow rate will change.
10.
When the required temperature is reached, turn to the
STOP
position to stop the
flow. Water may continue to flow from the handset for a few moments during
shut-down, as water is purged from the tank. Isolate the power at the double pole
switch.
11.
A small amount of water may be retained in the shower fitting after the shower
control has been turned off. This may drain over a few minutes.
Note!
A slight hissing sound may be heard from the appliance during operation.
High mains water pressure and high shower temperatures will effect the tone.
This is quite normal when the shower is in use.
