The ground must be connected.
6.
Don't pull the power wire strongly.
3.5.2 Requirements for Electric Safety
1.
First install wire of outdoor unit and then wire of indoor unit. After finishing wiring and piping,
connect the unit to the power supply.
2.
Please strictly follow the instruction of this manual when installing indoor unit and its piping.
3.
The unit is subject to change without prior notice.

Please read this manual carefully before installation. If the unit power is too large, the power
supply circuit supplied for the unit should accord with the followings:
a. Installed the air switch with suitable capacity, please refer to the following, the air switch must
have the functions of magnetic tripping and heat tripping. (Note: never use the fuse to protect the
branch circuit.)
b. The capacity of wire diameter should be 1.5 times larger than the unit max. current.
c. Installed the creepage protector with enough capacity.
d. Make sure to divide the branch circuit for the special circuit.
f. The min. clearance between combustible surface and the air conditioner is 1.5 meters.
g. The indoor unit and outdoor unit must be reliably earthed.

Notes:
①
Please pay attention to surrounding conditions (eg. Ambient temp., direct sun shine, rain drops etc.)
②
Power cord or power connecting wire must be copper cored cable according with national criteria.
③
The indoor unit and outdoor unit must be reliably earthed.
④
The outdoor signal line leading out of the electric box must be separated from the power cord and
shall not be tied together. They must be kept at a distance of 10cm to the least. If they cannot be
routed separately in actual application, make utmost to avoid routing in parallel.
3.5.3 Requirements for Earthing
1.
The air conditioner is the first class electric appliance:
2.
The yellow and green dual color wire in the air conditioner is earth wire, it cannot be used for other
purposes, do not cut off it. Do not fix it by the tapping screw: otherwise, it can cause the electric
shock.
3.
The power supply must be reliably earthed and please do not connect the earth wire to the
following places:
①
Water pipe
②
gas pipe
③
Drainage pipe
④
The place where unreliable is
suggested by the professional.
