8. Operation

When the shower is turned on, rain droplets will gradually drip
from the rain nozzles and water will briefly stream from the
deluge nozzles until the panel reaches full flow.

Activate the deluge function by pressing the push button valve or
the icon on the digital valve user interface. Water will stream
from the centermost deluge nozzles for about eight seconds.

NOTE: For optimal deluge performance, wait about 30 seconds
between activations of the deluge function. Activating the deluge
function more frequently may reduce the amount of water streaming
from the deluge nozzles and dripping from the rain nozzles.

NOTE: When the water is turned off, the deluge function will
activate automatically. Water will continue to drip until no water is
retained in the showerhead.
