Operation
AHo 40 MTH
With the twin-handle tap, you draw hot water by turning
the right handle. You can draw cold water by turning the
left handle only.
If you turn both handles you can mix the required tem-
perature by opening and closing off the water flow as
appropriate.
5. Cleaning, care and
maintenance
Clean the taps with a damp cloth. Never use abrasive or
corrosive cleaning agents.
Descale the jet controller if it is clogged with limescale.
Remove it from the pivoting spout to do this.
6. What to do if ...
6.1
... there is no hot water
Although the draw-off valve is fully opened. In this case, it
could be that the small instantaneous water heater has not
heated the water because there is no power. Check the
MCB/fuse and residual current device in your fuse box.
6.2 ... the water flow rate is weak
It could be that the jet controller in the tap is contamina-
ted or scaled up. In this case clean the jet controller or
descale it. You can order the jet controller from us as a
spare part:
◦ AHEu 40 MTH part number 254568
◦ AHEu 40 MTH / AHEu 40 MTH part number 254574
