Cut Out Dimensions – The cut out in wall should be 8.81” 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 trim comprises of well finished trim plate and handle knobs. The trim plate is used to cover the wall and has markings for ON/OFF, 1/2/OFF and HOT/COLD for temperature control handle and volume control handles. 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. Any *4501 series trim can be used with this valve. Depending upon the shower model, trims can be of different shape and size, varying from square to circular shower handles.
