Before You Begin (cont.)
IMPORTANT! If the supplied toggle anchor fasteners are not used
to install the shower column:
Ensure that adequate strength wall backing materials and stud
bracing are properly positioned behind the finished wall.
Obtain proper fasteners (not provided) taking into account the
type of stud bracing material and thickness of the mounting
collar, finished wall, wall backing, and stud bracing.
Fasteners must be corrosion-resistant and capable of 300 lbs (136
kg) load bearing per fastener.
A minimum of two fasteners are required per mounting collar.
Fasteners must be securely anchored into the stud bracing to
adequately support the product.
IMPORTANT! For retrofit/remodel installations: Check the existing
shower enclosure for adequate clearances before proceeding with the
shower column installation. Refer to the Roughing-in for the shower
column and showerhead.
Verify the distances between:
• The ceiling and the center of the existing shower arm at the
finished wall surface.
• The shower floor and the center of the existing shower arm at the
finished wall surface. Ensure sufficient clearance under the
showerhead.
• The center of the existing shower arm and the center of the
mixing valve trim.
