Notes (1) The data are measured at the following conditions.
Item Indoor air temperature Outdoor air temperature
Standards
Operation DB WB DB WB
Cooling 27ºC 19ºC 35ºC 24ºC ISO-T1, JIS C9612
Heating 20ºC – 7ºC 6ºC ISO-T1, JIS C9612
(2) The operation data are applied to the 220V, 230V or 240V districts respectively
(3) The refrigerant quantity to be charged includes the refrigerant in 7 m connecting piping. (Purging is not required even in the short piping.)
If the piping length is longer. (When it is 7 to 15 m, add 20 g refrigerant per meter.)
(4) When the unit is operated in cooling or dehumidification mode at the outside air temperature of 1ºC and less, there is a possibility that water leakage
occurs at the indoor unit.
