• (*) When ambient temperature is less than 30 ºC, outdoor fan volume decrease.
• The above curves indicate pressures under the following conditions:
– Indoor fan speed: HIGH
– Indoor total capacity: 100% compared with the capacity of the outdoor unit. (Connected 1indoor unit for
RAS-(2-6)HVRN(1)(S)(E) and connected to two indoor for RAS-(8/10)HRNSE)
– Piping length: 7.5 m (main piping: 5m, branch piping for RAS-(2-6)HVRN(1)(S)(E): 2.5 m x 4, branch piping
for RAS-(8/10)HRNSE): 2.5 m x 2).
• Do not use the above data for the refrigerant charge procedure.
– These data should be used as a reference for the checking of operating conditions.
