NOTES
In case of using a central remote control, connect it to the unit in accordance with th attached installation manual.
X24A, X33A and X335A are connected when the optional accessories are being used.
Remote control model varies according to the combination system, confirm engineering data and catalogs, etc. before connecting.
Confirm the method of setting the selector switch (SS1, SS2) by installation manual and engineering data, etc.
In case of self cleaning panel follow the self cleaning panel installation instruction.
