Function

The open vented (non-pressurised) appliance is only suitable for
undersink installation. The appliance is intended to heat cold
water for supplying a single draw-off point. It must only be used
with a non-pressurised tap.
Thermostop function
The thermostop function (thermal separation) prevents the tap
becoming hot in standby mode.
Anti-drip function
The anti-drip function prevents expansion water from escaping
from the tap during heating. When water is heated, gas bubbles
are formed. The amount of gas bubbles depends on the water
quality. At temperatures >75 °C, the rising gas bubbles can
cause residual water to drip from the tap outlet.
Subject to design, some taps have a tendency to drip for a short
while after being closed. This dripping is caused by residual wa-
ter escaping from the tap outlet and is not linked to expansion
water.
