1) Unless otherwise specified, leave the switch to OFF where indicated by "-," which may be set to OFF for a reason.
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 24)
4) The table below shows the combination of SW2-9 and SW3-5 settings and the target evaporating temperature setting that
