Adjusting the Tiling Frame
Each shower drain is provided with a series of #10-24 x 7/8 flat head hex socket screws that thread into sealed blind-hole
inserts, which are crimped to the shower channel. The screws have dual functions within the shower drain assembly:
1.) A number of screws serve as leveling devices for the tiling frame to support the frame at its required height location.
These screws are located below the tiling frame and can be accessed through tool holes directly above the screw heads.
2.) Other screws are located above the frame and secure the tiling frame down to the channel, once it is positioned
appropriately.
All of these screws are the same type and require a 1/8 [3] Allen wrench (provided) to adjust them.
To Adjust the Tiling Frame:
STEP 8:
Measure the required finish floor height from the top surface of the waterproofing membrane to the top edge of
the tiling frame.
STEP 9:
Loosen each #10-24 FHHSS that secures the tiling frame until the frame can move freely up and down.
STEP 10:
With the tiling frame resting on the leveling screws underneath, use the 1/8 [3] Allen wrench provided and insert
into the access holes to adjust the height of the #10-24 leveling screws upwards as needed. The leveling screws can be
adjusted at various elevations to raise the frame upward and to also help set the frame at a required pitch to meet the
finished floor surface.
To prevent damage to the channel inserts, DO NOT over-tighten the leveling screws lower
than the preset screw height furnished.
WARNING - TO AVOID DAMAGE TO OR COMPROMISE OF
THE THREADED INSERT SEAL, DO NOT OVER-TIGHTEN
THE FRAME SECURING SCREWS AND LEVELING
SCREWS BEYOND A TORQUE OF 20 IN-LBS.
THE FRAME LEVELING SCREWS ARE PRESET AT THEIR
LOWEST HEIGHT AND CANNOT BE TORQUED ANY
LOWER DURING INSTALLATION.
