(2) This packaged air-conditioner is manufactured and tested in conformity with the ISO.
(3) Sound pressure level indicates the value in an anechoic chamber. temperature. During operation these value are somewhat
higher due to ambient.
(4) The operation data indicates when the air-conditioner is operated at 400V50Hz or 380V60Hz.
(5) The factory E.S.P. setting is set within the range of 80-150 Pa. If SW8-4 is turned to "ON", E.S.P. setting range can be
changed to 10-200 Pa.
(6) If wireless remote control is used, only 3-speed fan setting (Hi-Me-Lo) is available.
