Z_ Warning:
In case of A-control wiring, there is high voltage potential on the S3 terminal caused by electrical circuit design that has no electrical insulation between power
line and communication signal line. Therefore, please turn off the main power supply when servicing. And do not touch the Sl, S2, S3 terminals when the power
is energized. If isolator should be used between indoor unit and outdoor unit, please use 3-pole type.
/_ Warning:
• Turn on the main power when the ambient temperature is -20°C, -4°F or higher.
• In below -20°C, -4°F condition, it needs at least 4hr standby to operate in order to warm the electrical parts.
