16.1 GENERAL CHECK
1 Ensure that the eld-supplied electrical components (mains
power switches, circuit breakers, wires, connectors and wire
terminals) have been properly selected according to the elec-
trical data indicated. Make sure that they comply with national
and regional electrical codes.
2 Following the Council Directive 2004/108/EC(89/336/EEC),
relating to electromagnetic compatibility, next table indicates:

4 Check to ensure that the power supply voltage is within +/-
10% of the rated voltage.
5 Check to ensure that power supply has an impedance low
enough to warranty not reduce the starting voltage more than
85% of the rated voltage.
6 Check to ensure that the ground wire is connected.
7 Connect a fuse of specied capacity.
NOTE
Check and test to ensure that if there is more than one source of
power supply, that all are turned OFF.
CAUTION
• Check to ensure that screws for terminal block are tightly
tightened.
• Check to ensure that the indoor fan and the outdoor fan have
stopped before electrical wiring work or periodical check is
performed.
• Protect the wires, drain pipe, electrical parts, from rats or
other small animals. If not protected, rats may damage unpro-
tected parts, and at the worst, a re will occur.
• Wrap the accessory packing around the wires, and plug the
wiring connection hole with the seal material to protect the
product from any condensed water and insects.
• Tightly secure the wires with the cord clamp inside the indoor
unit.
• Lead the wires through the knockout hole in the side cover
when using conduit.
• Secure the cable of the remote control switch with the cord
clamp inside the electrical box.
• Electrical wiring must comply with national and local codes.
Contact your local authority in regards to standards, rules, re-
gulations, etc.
• Check that the ground wire is securely connected.
• Connect a fuse of specied capacity.
DANGER
• Do not connect of adjust any wiring or connections un-
less the main power switch is OFF.
• Check that the earth wire is securely connected, tagged
and locked in accordance with national and local codes.
