rmly so that the unit will not topple or fall.
Before starting installation work, turn off the power of this unit and the
connection destination. Do not turn on the power again until installation
is completed. Otherwise, it will cause electric shock or re.
Use the accessories or specied connection cables. Do not modify
connection cables other than those specied, do not use extension
cords, and do not use independent branch wiring. The allowable current
will be exceeded and cause electric shock or re.
Install the remote controller cables securely to the terminal block.
Conrm that external force is not applied to the cable. Use remote
controller cables made of the specied wire. If intermediate connection
or insertion xing are imperfect, it will cause electric shock, re, etc.
When connecting the remote controller cable, route the cables so that
the rear case of this unit is securely xed. If the rear case is imperfectly
xed, it may cause re or overheating of the terminals.
Always fasten the outside covering of the connection cable with the
cable tie. If the insulator is chafed, electric discharge may occur.
CAUTION
Do not set the DIP switch of this unit except as specied in this manual
or the operating manual supplied with the air conditioner. Setting the
switches other than specied will cause an accident or trouble.
