Table 23: ARNU183TSA4, ARNU243TSA4 Cooling Capacity Table.
ARNU183TSA4, ARNU243TSA4
TWO-WAY CEILING CASSETTE
TC: Total Capacity (MBh); SHC: Sensible Heat Capacity (MBh).
Cooling range with the Low Ambient Baffle Kit (sold separately) installed on the outdoor unit(s) is -9.9°F
to +122°F, and is achieved only when all indoor units are operating in cooling mode. Does not impact
heat recovery system synchronous operating range.
The System Combination Ratio must be between 50–130%.
Rated capacity is certified under AHRI Standard 1230. Ratings are subject to change without notice.
Current certified ratings are available at www.ahridirectory.org.
For outdoor unit performance data, see the respective outdoor unit performance data manuals on
www.lg-vrf.com.
