2) A: Only the switch on either the OC or OS needs to be set for the setting to be effective on both units.
B: The switches on both the OC and OS need to be set to the same setting for the setting to be effective.
C: The setting is effective for the unit on which the setting is made.
3) The noise level is reduced by controlling the compressor frequency and outdoor fan rotation speed.
Setting of CN3D is required.(page 27)
4) Set SW3-6 to OFF (ºC setting) after servicing.
5) The refrigerant oil recovery operation can be cancelled and normal operation can be started if Stage 3 in the cooling mode or Stage
