• Before commissioning for the first time and each time the appliance is emptied (e.g. due to work on the plumbing system, if there is a
risk of freezing or in case of maintenance), the appliance must be vented correctly in accordance with the instructions in this manual.
• Do not remove the front cover under any circumstances before switching off the mains electrical supply to the unit.
• Never make technical modifications, either to the appliance itself or the electrical leads and water pipes.

6. Description of applicance
The Zip instantaneous water heaters are compact electronically controlled water heaters. It is intended to provide economical heating of
water for a wash basin when installed together with a sanitary water fitting. When the hot-water tap is opened, the heater switches itself
on automatically when the minimum water flow rate is exceeded and heats the water as it passes through the appliance.
There are 3 available temperature settings, 35ºC, 38ºC and 45ºC (Max).
For best performance, always fit the special flow controller included with the appliance. This controller is inserted into the outler at the
end of the tap and fits into any standard sleeve size M 22/24.
The maximum possible outlet temperature is determined by the temperature of the incoming water, the rate of flow and the heating
power of the appliance.
This appliance delivers water not exceeding 50ºC in accordance with AS3498.
7. Operation
Three coloured LEDs
Touch key
Temperature setting
The “Touch” key
allows you to select one of three preset temperatures.
Every key press sets the temperature to the next level:
35 °C >
Pressing the key
> 38°C >
once again, starts the cycle all over.
45°C (MAX) >
>
>
35°C
The currently selected temperature is indicated by one of three coloured LEDs.
Key lock and temperature lock
The currently selected temperature setting can be locked against unintended changes. Thus, the temperature cannot be changed by a
single keypress.
Activate keylock / Deactivate keylock:
Press “Touch” key (for approx. 5 seconds) until the active LED goes out, then release “Touch” key.

8. Additional features
Activate / De-activate LED display
As part of the appliance’s energy saving feature, the active LED will automatically turn off 20 seconds after the last operation (e.g. tapping
or temperature selection).
To identify the current / selected setting at any time, the LED display can be enabled permanently therefore disabling the LED standby
function:
• Turn off the water at the outlet from the appliance.
• Press and hold the “Touch” key for at least 7 seconds. NB: the LEDs will go out after 5 seconds for a period of approximately 1.5 seconds then light up again.
• While still holding down the “Touch” key, turn on the outlet tap. The LED will go out as confirmation that this option is now selected.
• Release the “Touch” key and turn off the outlet tap.
If the tap is opened or the touch key is used in LED standby mode (LED off), the last active LED lights up (wake up), but the temperature
setting will not change yet. Only when pressed once again, the temperature setting will be adjusted.
The LED Standby function can be re-activated using the same process above.
NB:
This function is retained even after power failure.
