The RCD 5389.0 is a drain trap assembly designed to manage condensate drainage in HVAC systems. It creates a water seal that prevents air bypass and backdrafting through the condensate drain line, protecting system efficiency and indoor air quality. The assembly measures 4.6 inches in length, 2 inches in width, and 10 inches in height, making it a compact fit for tight equipment installations. At 1.55 pounds, it is lightweight and straightforward to handle during service calls. CSA Listed and manufactured in the USA, this part meets recognized safety and quality standards expected in residential and light commercial HVAC applications.
This drain trap assembly is suited for use in forced-air cooling systems, air handlers, and furnaces with cooling coils that produce condensate during normal operation. It is typically installed at the condensate outlet of the evaporator coil or drain pan, where maintaining a proper trap seal is essential for correct system operation. HVAC technicians install this part during new equipment startup, seasonal maintenance, or when replacing a failed or clogged drain trap on existing equipment.
Designed as an OEM-style replacement drain trap assembly for residential and light commercial HVAC systems requiring a condensate drain trap at the evaporator coil or air handler drain outlet.
Installation should be performed by a licensed HVAC technician. Shut off power to the air handling unit or furnace at the disconnect before beginning work. Ensure the trap is oriented correctly per equipment manufacturer guidelines to maintain the condensate seal under both positive and negative cabinet pressure conditions. Check local mechanical codes for required trap depth and priming procedures before returning the system to service.
