Important notes for installation

When installing the front panel, please pay attention to correctly insert the square tube into the latch, the square tube is marked with “THIS SIDE UP”. The wrong angle of the square tube will cause the door to not lock after installation. There are two small protrusions on the bottom of the rosette of the door handle, which are used to fix it firmly on the wooden door. Pay attention to the protrusions when you install it on the metal door. After installation, check whether the front and rear handles can return to their original positions or not after they are turned every time. If not, please adjust the front and rear panel fixing screws to ensure that the handle will return to the original position, otherwise the code will not be unlocked occasionally. Because the knob is a heavy-duty design,if use the key to access, PLEASE NOTE:rotate the knob help the key to turn the latch, so this makes it easy to open the door.
