1. Install the Support Framing and Bracket

NOTE: These instructions show one possible ceiling conﬁguration.

Adapt to ﬁt your application.

Using 2x4s, construct support framing to mount the bracket. The

face of each 2x4 should be installed ﬂush with the face of the

ceiling joists.

Ensure that each corner of the bracket can be mounted to the

support framing with at least 2 screws.

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.
