Notes
(a) the refrigerant charge for the 8/10kW model is as high as 1.84kg. It is the allowed maximum charge for the
split type unit. If more charge is required, the indoor ventilation equipment must be equipped. Therefore, in the
case of increasing the length of the connecting tube, there is no need to add refrigerant to the unit.
