3. Technical data

The Zip instantaneous water heaters are compact electronically controlled water heaters. It is intended to provide economical heat-

ing 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 appli-

ance.

There are 3 available temperature settings, 35°C, 38 °C and 45 °C.

For best performance, always fit the special flow controller included with the appliance. This controller is inserted into the outlet 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 appliances deliver water not exceeding 50°C in accordance with AS3498.

6. Operation

Temperature setting

The touch key allows you to select one of the three preset temperatures.

Every key press sets the temperature to the next level:

35 °C 38 °C 45 °C (max.)

Press the key once again starts the cycle all over.

The current selected temperature is indicated by one of three coloured LEDs.

Key lock and temperature lock

The current selected temperature setting can be locked against unintended alteration. Thus, the temperature cannot be changed by

a single keypress anymore.

Activate keylock / Deactivate keylock:

Press and hold touch key for approx. 5seconds until the active LED goes out, then release the touch key.

Three coloured LEDs

Touch key

Additional features

As the control panel’s energy saving feature, the active LED turns off automatically about 20seconds after the last operation (e.g.

tapping or temperature selection).

To identify the selected setting at any time, the LED can be enabled permanently and the LED standby function will then be disabled

with the following procedure:

• Close tap (water stop).

• Keep sensor key touched permanently for more than 7seconds. Due to the keylock function the LED always goes out after 5sec-

onds for about 1.5seconds and lights up again.

• While still holding down the key, open the tap now, the LED will go out shortly as confirmation.

• Then release the touch key and close tap (water stop).

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 tempera-

ture setting will not change yet. Only when pressed once again, the temperature setting will be adjusted.

The LED Standby function can be activated in the same way again.

NB:

This function is retained even after power failure.

7. Cleaning and Maintenance

• The appliance and the fittings should only be cleaned with a damp cloth. Do not use

abrasive or chlorine-based cleaning agents or solvents.

• Keep the control panel area dry!

• Clean the flow controller or the hand-shower regularly and replace as necessary.

• Dirt and scale deposited in the pipes and heater will affect the function of the

heater. Typical indications include reduced rate of flow or noisy flow. In such cases,

have the heater inspected by a technician and, if necessary, have the filter in the

cold-water inlet cleaned.

Instructions for user - MCX - 801052 - January 2020 v1.20 Art.no: 9120-15036
