Apparatus for connecting a first pre-charged section of an air conditioning system to refrigerant lines connecting the section to a second section of the system. A service unit is employed to connect each refrigerant line to the pre-charge section which includes a body fabricated from a square or rectangular piece of bar stock. A main channel is formed through the bar stock and one end of the main channels is coupled to a suitable system component in the pre-charged section by a tube. A connector having a penetratable seal is mounted in the opposite end of the channel. The connector has a male fitting that is threaded into a female fitting. One fitting is mounted in the opposite end of the main channel and the other fitting is mounted in the refrigerant line. The seal is ruptured or broken when the male fitting is threaded into the female fitting a sufficient depth to establish a leak proof joint therebetween. A process valve is also mounted on the bar stock body and communicates with the main channel via an auxiliary channel. The process valve is used in the factory to charge refrigerant into the section prior to the section being shipped into the field.

A multipoise furnace cabinet includes right and left sides with top and bottom plates connecting upper and lower parts of the right and left sides together. In one embodiment, top and bottom plates include vent cutouts. A side of the top plate has a first partially cut section that aligns with a second partially cut section in a door to the furnace cabinet, wherein the first and second partially cut sections substantially describe a circle, such that when the first and second partially cut sections are removed from the door and the cabinet, a resulting opening permits entry of a flue vent pipe. Front edges of the right and left cabinet sides are flanged, as are the front edges of the top and bottom plates. In another embodiment, the vent cutouts are entirely within the door.
