An integrally threaded brass insert is molded into the discharge conduit of a condensate pan such that a steel drainage pipe can be threadably engaged to the insert without causing damage to the plastic discharge conduit. Bonding between the insert and the surrounding conduit is enhanced by providing a knurled surface on the outer periphery of the insert.

Molded drain connection with insert

A mounting arrangement for securing a tubing subassembly without requiring fixturing of the tubing relative to a coupling is disclosed. A mounting bracket including arcuate openings is designed to receive the coupling. A mounting flange having fastener receiving openings is positioned to secure the coupling in position such that fasteners may be inserted through the arcuate slots to secure the mounting bracket to the mounting flange to maintain the coupling and the attached tubing subassembly in the desired configuration and orientation.

Method and apparatus for mounting coupling and tube assemblies to

An indoor fan coil unit of a split type air conditioning or heat pump system. This indoor unit has a non-metallic polygon shaped casing with duct connections extending through each side. A cylindrical heat exchanger is mounted within the casing and a blower is mounted through an opening in the top of the casing within the heat exchanger. The blower draws air through the top of the casing and directs the air through the heat exchanger and out each duct connection to the ducts connected to each space to be conditioned.

Polygon fan coil cabinet and method of assembly

A method and apparatus for forming heat exchanger assemblies with bendable tube sheet flanges is disclosed. A single tube sheet having a bending slot defined thereby and including a connecting portion for joining two portions of the tube sheet is disclosed. Separate coil cores are formed in each portion of the tube sheet such that the tube sheet may be bent to one configuration for allowing simultaneous soldering of the two coil cores in a side by side relationship. Thereafter, the tube sheet may be bent in an opposite direction to secure the ends of the coil cores together to help form an inverted V-shaped heat exchanger assembly.
