TO BE USED WITH THE TVH.4511 OR TVH.4371 VALVE Handle Operation – The handle of the *4511 trim set is used to control volume of water flowing through the valve. It can be used to set the water to a trickle all the way to full volume flow. Valve Installation – This trim is paired with the TVH.4511 or the TVH.4371 valve. As the valve is installed, care should be taken to maintain proper distance from the back of the valve to the surface of finished tile which should be between 2.77? and 3.44?. Also, the valve must be installed vertical and not at an angle. In case, a tile is thicker, or wall is deep, extensions are used for elongating both handles of the valve to ensure proper setting of the trim (length of extensions for TVH.4511 valve is 1.40? inches). Cut Out Dimensions – The cut out in wall should be 1.65? X 1.65? inches which is properly covered by the trim plate. This will ensure that the trim plate will cover the cut out hole in the wall.
