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.

securely held in place during installation, the product may
fall causing personal injury.
Align the bracket so that its edges are parallel to the shower
walls. Orient the inlet pipe hole for the easiest connection to the
water supply.
Install the bracket with at least 2 #8 1-1/2″screws per corner.
Screws may be installed in any two of the four holes per corner.

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.
