To ensure safety of the building occupants, the air
handler is equipped with a refrigerant leak detection
system. The system is comprised of a refrigerant
sensor and a mitigation control board. The system
automatically detects leaks in the indoor coil and
initiates actions to mitigate the risk of ignition of the
leaked refrigerant, including:
• Turning on the blower of the indoor unit to dilute
leaked refrigerant;
• Fully opening any zoning dampers, when
applicable;
• Turning off the compressor of the outdoor unit;
• De-energizing potential sources of ignition
connected to the system;
• Energizing an audible alarm, if so equipped.
Examples of potential ignition sources that are de-
energized include electrostatic air cleaners.

Refrigerant sensors for refrigerant leak detection
systems shall only be replaced as specified by the
manufacturer.
Minimum Conditioned Space
The installer must verify that the total space
conditioned by the system is large enough to safely
dilute any leaked refrigerant in the event of a
refrigerant leak of the indoor coil.
The minimum space conditioned by the appliance shall
be according to Table 3, p. 10. The conditioned space
includes any parts of the space connected via an air
duct system. The altitude of installation is the altitude
above sea level of the site where the equipment is
installed.
