Note:
All the wires should be copper core wires.
The power cable of indoor unit should be equipped according to the operation manual indoor unit.
When connecting the indoor & outdoor wire, check the number of the indoor & outdoor terminals, the
terminals with the same number connected together with one wire.
Incorrect wiring will damage the controller of the air conditioner or make the unit work abnormally.
The air conditioner must use special power circuit and special air switch (40A), groundign wire. The
wiring work should be done by a qualified electrician according to the national wiring rule.
The creepage breaker must be installed. The grounding line and the neutral line of the receptacle must
be strictly separated. It is incorrect to connect the neutral line with the grounding line.
The connection type of power cord is Y connection. If the soft power cord is damaged, to avoid risk, it
must be replaced by the manufacturer or their specific repair department or similar professional worker.
(Sketch map)
1. Power supply
Air conditioner must use an exclusive line (over 30A)
When installation air conditioner in a wet place, try to use a circuit breaker against
Current leakage.
For installation in other places, use circuit breaker as far as possible.
The parameter of power cord is over 2.5mm .
Others
The breaker of the air conditioner should be all-pole switch ; and the distance between its
two contacts should be no less 3 mm.
Note: The terminal blocks mark at the two ends of the
connection wire should be corresponding one by one,
otherwise the air conditioner cannot work normally.
Electric wiring
Connect wire between indoor & outdoor unit
As the wiring diagram show to arrange the connection
wire.
2.The wiring method of straight terminal For those
connection wires whose end are not orbicular terminals,
their wiring method is: Loosen the connecting screw, insert
the end of the wire directly into the terminal block, and then
tighten screw. Pull the wire outwards slightly to confirm it
is held tightly.
3.Pressing method of connection wire:
After wiring, the connection wire must be pressed with
wire holding clamp. The wire holding clamp should press
on the out cover of the connection wire. As the right figure
shown:

1.The wiring method of orbicular terminal
For the connection wire which end is orbicularterminal, its
wiring method is as the right figure shown. Dismantle the
screw and put it through the ring at the end of the connection
wire, then connect it to the terminal block and tighten the
screw.
