unit is to be installed, and run refrigerant and drain piping,
remote controller cord, and outdoor/indoor transmission
wiring to the unit's piping and wiring hole. (For wiring pro-
cedure, refer to "WIRING EXAMPLE AND HOW TO SET
THE REMOTE CONTROLLER." For piping procedure,
refer to the attached installation manual of the outdoor
