3 Appliance
description
This tap is intended for operation with an open vented (zero
pressure) oversink water heater.
The pivoting spout is fi tted with a jet controller, except WDM.
The volume of water expands as the water heater
is heated up. Expansion water drains from the tap.
This is a necessary and normal process.
4 Operation
You can draw hot water by just activating the right hand tap
handle. You can draw cold water by just activating the left hand
tap handle.
When you activate both handles you can mix the required
temperature by opening and closing the water streams as
appropriate.
With the WBM tap you can switch between the pivoting spout
and the hand shower. For this press the changeover control while
drawing water.
After drawing has fi nished the tap automatically resets itself so
that when next time water is drawn, it will fl ow from the pivoting
spout again.
5
Cleaning, care and maintenance
Clean the taps with a damp cloth. Never use abrasive or corrosive
cleaning agents.
Descale the perlator if it is clogged with limescale. Remove it from
the pivoting arm to do this.
