Specifications
Indoor Unit
275
Slim Ceiling Mounted Duct Type
Notes:
1 Nominal cooling capacities are based on the following conditions:
Return air temperature: 80°FDB, 67°FWB
Outdoor temperature: 95°FDB
Equivalent ref. piping length: 25 ft (7.5 m) (Horizontal)
2 Nominal heating capacities are based on the following conditions:
Return air temperature: 70°FDB.
Outdoor temperature: 47°FDB, 43°FWB
Equivalent ref. piping length: 25 ft (7.5 m) (Horizontal)
3 Capacities are net, including a deduction for cooling (an addition for heating) for indoor fan motor heat.
4 External static pressure is changeable to change over the connectors inside electrical box, this pressure means
"High static pressure – Standard – Low static pressure".
5 Anechoic chamber conversion value, measured under JISB8616 conditions. During actual operation,
these values are normally somewhat higher as a result of installation conditions.
