Installation
Connect the Heavy Duty model using the 12 V power pack (supplied) to a 240 V power outlet, which needs to be located outside the bathroom. A power outlet can sometimes be found in the roof cavity, servicing the ceiling fan.
The flat finished surface of the wall must extend at least 80mm above the centre of the water outlet. That may require a few extra tiles.

The shower head is not supplied. Your existing shower head can often be re-used. Or, to save even more money, replace your current shower head with a Water Saving shower head.
How It Works
Once in the shower, push the ‘Start’ button and turn on the water. The hot and cold water taps still control the temperature and water flow, as per usual.
The LED visual display will then begin counting down your remaining available showering time in minutes. An audible ‘beep’ will occur at the completion of every minute.
At the 99 second point, the display will switch to indicating remaining time in seconds. To support this, audible ‘beeps’ will occur at 30, 20,10, 5, 4,3, 2, 1 seconds.
The water is now automatically cut off and the now ‘flashing’ visual display will begin counting down remaining waiting time till the shower can be re-used.
Please note
Pressing the ‘Start’ button at any time during the available showering time or waiting time has no effect.
Programming
Program your available showering time choosing from 0 – 12 minutes.
Pre-Program your waiting time (between showers), choosing from 0, 15, 30, 60, 120, 300 second options.
The available showering time displays as a steady glow and the waiting time displays in a flashing format.
Power failure will not change these settings.

Trouble Shooting
Screen blank
Check that 12 Volt power is reaching the circuit board. No display when power is connected suggests reversed polarity. Remove the plug from the socket on the circuit board, remove the back of that plug from the 2 pin socket on the end of the lead and reverse it. The centre of this plug should be positive with respect to the sleeve of the plug.
Cold water feeding back into hot system
If there is significant difference in pressure between hot and cold water, this can be a problem when the user leaves hot and cold taps turned on after the shower is finished.
That can cause back flow when there are multiple showers and the hot water is cooled by the cold coming from those open taps. One solution is to fit a one way valve in the hot feed to the shower.
