Description
The Heatcraft Refrigeration 40496003 Secondary Drain Pan is a condensate collection component placed beneath to capture overflow water when the primary drain system does not remove moisture effectively. It works by providing a containment area that channels excess vapour away from essential components, reducing the water leakage and structural damage. In air conditioning and refrigeration HVAC systems, it acts as a backup safeguard beneath evaporator units or air handlers. Positioned under the equipment during setup or replacement, it contributes to proper moisture management.
