IMPORTANT: Any economizer that meets the economizer
requirements as laid out in California’s Title 24 mandatory
section 120.2 (fault detection and diagnostics) and/or
prescriptive section 140.4 (life-cycle tests, damper leakage,
5 year warranty, sensor accuracy, etc), will have a label on
the economizer. Any economizer without this label does
not meet California’s Title 24. The five year limited parts
warranty referred to in section 140.4 only applies to factory
installed economizers. Please refer to your economizer on
your unit.
