I. Rough in Valve Installation
Note: Use plumbers tape or equivalent to seal all threaded port joints. This valve is design to fit in
a 2" X 4" stud wall (or thicker) installation. Use stem extension kit #20-146 (sold seperately) if
valve installed is too far away from the finished wall.
1. Do not remove mud cover from valve before locating mounting surface depth in the wall.
2. Do not turn the cartridge stem - temperature settings are pre-calibrated at the factory.
3.
Mount valve to cross support using screws (not included). Valve shall be perpendicular and fixed
firmly to cross support to achieve proper trim attachment.(See Fig 1).
4.
Place the cross support with valve between wall studs. The min./max. valve depth and vertical
height desired within tub/shower enclosure determines the exact cross support placement.
Attach cross support to wall studs.(See Fig 2).
5.
Ensure opening in finished wall comes in contact with the mudcover to ensure seal with
Thermo Wall Plate shown in Fig. 4. (See TEMPLATE FOR FINISHED WALL OPENING in Fig 9).
