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
Touch key
Three coloured LEDs
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 >
> 38°C >
>
45°C (MAX) >
>
35°C
Pressing the key
once again, starts the cycle all over.
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 sec-
onds 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.

9. Maintenance
• The appliance and fittings should only be cleaned with a damp cloth. Do not use abrasive or chlorine-based cleaning agents or sol-
vents.
• Keep the control panel area dry!
• Clean the jet regulator regularly and replace as necessary.
• Dirt and scale deposited in the pi
pes and appliance will affect its function. Typical indications of this are a reduced flow rate or noisy
flow. In such cases, have the appliance inspected by a qualified technician and, if necessary, have the filter in the cold-water inlet
cleaned.
10. Fault finding
