Code Compliant Specifications

The International Mechanical Code (IMC) is published by the International Code Council (ICC) and protects public health and safety for all building heating, cooling and ventilation related design, installation and inspection by providing minimum safeguards for people at homes, schools and workplace. Fuel burning appliances, cooling systems, heating systems appliance venting, location and protection of appliances and many other such issues are addressed in the IMC.

The IMC is the most widely used mechanical code in the United States and is also used as the basis for the mechanical code of several other countries. The IMC is in use or adopted in 43 states, the District of Columbia, NYC, Guam, Puerto Rico and the U.S. Virgin Islands.

Resource Conservation Technologies provides contractors with the flexibility to meet or exceed international code requirements and multiple municipality codes being enforced in many states today with our code compliant condensate overflow switches and secondary drain pan product lines including:

International Mechanical Code
307.2.3 Auxiliary and Secondary Drain Systems

In addition to the requirements of Section 307.2.1, where damage to any building components could occur as a result of overflow from the equipment primary condensate removal system, one of the following auxiliary protection methods shall be provided for each cooling coil or fuel-fired appliance that produces condensate:

  1. An auxiliary drain pan with a separate drain shall be provided under the coils on which condensation will occur. The auxiliary pan drain shall discharge to a conspicuous point of disposal to alert occupants in the event of a stoppage of the primary drain. The pan shall have a minimum depth of 11/2 inches (38 mm), shall not be less than 3 inches (76 mm) larger than the unit or the coil dimensions in width and length and shall be constructed of corrosion-resistant material. Galvanized sheet steel pans shall have a minimum thickness of not less than 0.0236 inch (0.6010 mm) (No. 24 gage). Nonmetallic pans shall have a minimum thickness of not less than 0.0625 inch (1.6mm).
  2. A separate overflow drain line shall be connected to the drain pan provided with the equipment. Such overflow drain shall discharge to a conspicuous point of disposal to alert occupants in the event of a stoppage of the primary drain. The overflow drain line shall connect to the drain pan at a higher level than the primary drain connection.
  3. An auxiliary drain pan without a separate drain line shall be provided under the coils on which condensate will occur. Such pan shall be equipped with a water-level detection device conforming to UL 508 that will shut off the equipment served prior to overflow of the pan. The auxiliary drain pan shall be constructed in accordance with Item 1 of this section.
  4. A water-level detection device conforming to UL 508 shall be provided that will shut off the equipment served in the event that the primary drain is blocked. The device shall be installed in the overflow drain line, or in the equipment-supplied drain pan, located at a point higher than the primary drain line connection and below the overflow rim of such pan.

Exception: Fuel-fired appliances that automatically shut down operation in the event of a stoppage in the condensate drainage system.
