PMN D-GN-LC-1394 announced Light Commercial Rooftop and Split System current and pending regulations. As a follow-up to the prior PMN announcement, this PMN identifies the Commercial Split Systems DX11S, DZ11S and DAR models that will no longer be manufactured after December 31, 2017, because of new minimum energy efficiency standards that will take effect for commercial air conditioning and heating equipment manufactured on or after January 1, 2018.

However, inventory manufactured up to December 31, 2017 can be sold or installed to depletion (note that installations are subject to local permitting or building codes which may differ from the Federal minimum efficiency standards). In order to ensure all quotes and sold jobs are accommodated, last buy purchase orders for DX11S, DZ11S and DAR models must be placed no later than October 13, 2017. All last buy orders should be clearly identified as such, cannot be cancelled and must ship by December 31, 2017. Orders placed after October 13, 2017 are subject to remaining availability.
