GENERAL CHECK
1. Ensure that the field-supplied electrical components (mains
power switches, circuit breakers, wires, connectors and
wire terminals) have been properly selected according to
the electrical data indicated. Make sure that they comply
with national and regional electrical codes.
2. Check to ensure that the power supply voltage is within
+/-10% of the rated voltage.
3. 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.
4. Check to ensure that the ground wire is connected.
5. Connect a fuse of specified capacity.

DANGER:
Do not connect of adjust any wiring or connections unless

CAUTION:
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
unprotected parts, and at the worst, a fire 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, regulations, etc.
Check that the ground wire is securely connected.
-
Connect a fuse of specified capacity.
