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.
CAUTION: Risk of personal injury. If the bracket is not
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.

4. Install the Dropped Ceiling
Construct a 4″(102 mm) minimum to 4-1/2″(114 mm) maximum
dropped ceiling in the shower area. The framed cutout should be
centered around the bracket, with the framing 18-1/8″(460 mm)
+/- 1/8″(3 mm) apart in both directions.
IMPORTANT! Risk of product damage. Ensure cutout and framed
opening of dropped ceiling meet the required dimensions listed. If
the finished ceiling thickness exceeds 4-1/2″(114 mm), shim behind
the mounting bracket.
Trim copper inlet pipe to 1-1/4″(32 mm) above the plane of the
finished ceiling opening.
De-burr, clean, and lubricate copper inlet pipe to prevent damage
to the water inlet gasket when the shower unit is installed.

stick through the shower unit. The copper inlet pipe should stick
through the water inlet gasket. Loosely install four sealing
washers (metal side down) and nuts on the leveling nuts.
Place a level across the shower unit and level by adjusting the
leveling nuts.
Hold the leveling nuts and tighten the nuts.
