The TVH.4101 Thermostatic valve features 3/4″ NPT connections and has 1 water output. The bottom handle sets the temperature and the top handle controls the water volume.
SUPPLY STOPS – There are two safety stops at each water inlet to prevent water flow in case of installation and repairs.
HANDLE OPERATION – The bottom handle is used to control the temperature of water flowing through the outlet. The top handle is capable of controlling the volume of water from full flow to a trickle.
ANTI-SCALD RING – Over the temperature control knob, is an anti-scald temperature stop ring which is a safety feature in this thermostatic value. With the help of this ring, the temperature of the water is regulated. Covering this ring is the handle knob which has a push-button on the side. In order to adjust the water temperature, one needs to press this button and move the handle to a hot or cold direction. Without pressing it, the user will not be able to rotate the handle to the full HOT position – as an anti-scald prevention mechanism. The anti-scald temperature stop ring should be fitted tightly over the valve (tapping using a rubber mallet might be required) for it to function properly.
VALVE INSTALLATION – As the valve is installed, care should be taken to maintain a proper distance from the back of the valve to the finished tile which should be between 2.77” and 3.44” inches [Rough In Spec]. Also, the value must be installed straight and not at an angle or upside down. In case, the tile is thicker or valve installed in the wall is too deep, extension kits are available and can be used for elongating both handles of the valve.
CUT OUT DIMENSIONS – The cut out in wall should be 6.49” x 4.44” 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.
TRIMS – The trims comprise of a well-finished cover plate and handle knobs. The trim plate is used to cover the wall. Depending upon the shower model, trims can be of different shape and size, varying from square to circular shower handles.
