terminal cover firmly to avoid overheating, electric shock or even fire risk.
In the case of a refrigerant leakage during unit installation, keep the room well ventilated.
Check the unit upon installation. Be sure there is no leakage. Refrigerant will induce a poisonous
gas subject to heat.
Isolate power supply before touching terminal block.
WARNING
To maintain good picture or reduce noise, keep the unit at least 1m from T.V. or radio,
when installing the communication wire and power supply. (If the radio wave is relatively strong,
1m is not enough to reduce the interference).
