ABSTRACT:
A quick-release mounting apparatus for securing a unit controller assembly to the upper housing of an inlet vacuum valve for a vacuum sewerage system, for facilitating quick removal of the unit controller assembly, is disclosed. A base member, having slot-like shoulder portions on each respective side, is heat-staked to the top surface of the upper housing of the inlet vacuum valve. A quick-release mounting key member is then inserted into each of the respective shoulder slot openings on top of the mounting feet. The mounting key has respective keyed apertures to enable it to fit around certain portions of the unit controller. The mounting key has a centrally disposed spacer portion and a pair of elongated tine members, which are tapered and rounded at their respective ends. The mounting key is then pushed into the slot-like openings to secure a tight press fit of the mounting key, the mounting feet of the unit controlled assembly, within the slot-like openings of mounting base member. An alternative embodiment of the present invention allows the quick-release mounting key to have one of the tines to be longer than the other, at the end of which there is positioned an integral hook-shaped end fastener which fastens over the end of one of the mounting feet of the unit controller assembly. The quick-release mounting key has a handle portion at one end for easy insertion and removal of the mounting key from the base member.
