OPERATING THE SHOWER

To start the shower

Turn the power selector to the red or blue 
symbol positions and water will start to flow.

To stop the shower

Switch the power selector to the ‘STOP’ position 
and water will cease to flow.

To use the power selector

The power selector has four positions — STOP, 
COLD, ECONOMY and HIGH — as shown in 

fig.20

.

STOP is to switch off the electric and water 
supply at the shower — no flow or power used.
Blue symbol  is for cold water only.
Adjustment of the temperature control at this 
setting will only alter the force of the water 
from the shower head. IT WILL NOT ALTER THE 
WATER TEMPERATURE.
Single red symbol  is the economy setting 
for using less power during warmer months. 
Temperature adjustment at this setting is via the 
temperature control.

Note:

 If the stated flow rate required for the unit 

cannot be met due to low water pressure, it will 
be necessary to operate the unit on ‘ECONOMY’ 
setting during the warmer months because of 
flow rate limitations entering the unit.
Double red symbol    is the high setting which 
allows the highest flow achievable for your 
preferred temperature.  

WARNING!

Before normal operation of the 

shower, it is essential that the 

commissioning procedure has been 

completed correctly.

WARNING!

If restarting immediately after 

stopping, be aware that a slug of hot 

water will be expelled for the first 

few seconds.
