If other than 7.62m of tubing is used and/or indoor unit is located above outdoor unit, a slight variation in capacity may occur. † Total and sensible capacities are net capacities. Blower motor heat has been subtracted. ‡ Sensible capacities shown are based on 27°C entering air at the indoor coil. For sensible capacities at other than 27 °C, deduct 245 kw per 480 L/S of indoor coil air for each degree below 27°C, or add 245 kw per 480 L/S of indoor coil air per degree above 27 °C. When the required data falls between the published data, interpolation may be performed. ** Unit kw is total of indoor and outdoor unit kilowatts.
