Handle Operation - The handle is used to control temperature of water flowing through the outlet. This handle does not control the volume of water flowing through the valve.

Cut Out Dimensions - The cut out in wall should be 4.44” X 4.44” 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 well finished trim plate and handle. The trim plate is used to cover the wall and has markings for HOT/COLD for temperature control handle. 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, temperature of the water is regulated. Covering this ring is the handle knob which has a push button on the side. To adjust the water temperature, one needs to press this button and move the handle to 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 during installation) for it to function properly.

Depending upon the shower model, trims can be of different shape and size, varying from square to circular shower handles.
