I’d fall back to 6.4.1.1 under the mandatory provisions for the prescriptive compliance path – that’s the section citing the 6.8 series tables for the purpose of establishing prescriptive compliance. As I’m reading/interpreting, equipment that is not listed
categorically within the 6.8-series tables by extension does not need to achieve any minimum performance rating. There is however some complementary text there you’ll want to review carefully to see if anything applies to your situation.</div>

<div class="x_yiv7758473049MsoNormal">One extra thought: Is it possible you’re dealing with a 60-ton WSHP
<i>package</i>, comprised of a combination of smaller heatpumps? In that scenario it may be easier using the individual heatpump capacity ratings to find something that fits the prescriptive mold, so to speak.</div>
