Abstract
This invention relates to an inlet valve assembly for central vacuum systems and the method of installing the same. In particular, this invention relates to an inlet valve assembly including an inlet face plate, a mounting plate, having a deformable mounting flange, and an electrical receptacle integrally formed with a high voltage wire. In some uses, the inlet valve assembly also can include a low voltage wire which can be used to complete a low voltage circuit to initiate a central vacuum motor. The mounting plate can accommodate the electrical receptacle in a temporary position and the inlet face plate can rear mount the receptacle into a locked position where the receptacle is securely attached to the inlet face plate. In this manner, the receptacle may be mounted to the inlet face plate even though one end of the high voltage wire is already wired into an electrical box.
