DIMENSIONS (IN)
Capacity Ratings are based on sensible heat removal with a TEV fed, medium frosted coil when:
- SST (saturated suction temp.) is above -20°F. Derate 10% for -30%°F SST.
- Medium temp. selection – use 10 to 15°F TD. Low temp. selection – use 8 to 12°F TD. (TD is the the temp. difference between room and SST.)
- Derate 12% for 50 Hertz (0.88 multiplier) or increase TD to compensate for lower fan RPM – use 11.4°F for 10°F TD or 13.6°F for 12°F for TD.
