ICC-ES AC332 – Acceptance Criteria for Air Conditioner Condensate Drain Traps and Overflow Switches

Scope

ICC-ES AC332 outlines the acceptance criteria for air conditioner condensate drain traps and overflow switches. This criteria covers the following:

  • Drain traps:
    • Water-filled traps designed to maintain a water seal to prevent sewer gases from entering the building.
    • Mechanically sealed traps that use a float or other mechanism to seal the drain line when not in use.
  • Overflow switches:
    • Float-operated switches designed to shut off the air conditioner or trigger an alarm if the condensate drain line becomes clogged or overflows.

The scope of AC332 includes the following aspects:

  • Materials: specifies the requirements for the materials used in the construction of drain traps and overflow switches, ensuring their compatibility with condensate and their durability.
  • Design and construction: details the design and construction requirements for the traps and switches, including their dimensions, sealing mechanisms, and electrical components.
  • Performance: outlines the testing methods and acceptance criteria for evaluating the performance of the traps and switches, including their ability to maintain a seal, prevent overflows, and operate reliably under various conditions.
  • Installation: provides guidelines for the proper installation of drain traps and overflow switches, ensuring they are correctly positioned and connected to function effectively.

The AC332 acceptance criteria are used by manufacturers to obtain an evaluation report from ICC Evaluation Service (ICC-ES), which demonstrates that their products comply with the applicable plumbing and mechanical codes.
