Electrical Wiring

• Electrical construction should be made with specific mains circuit by the qualified personnel
according to the installation instruction. Electric shock and fire may be caused if the capacity of
power supply is not sufficient.
• During arranging the wiring layout, specified cables should be used as the mains line, which
accords with the local regulations on wiring. Connecting and fastening should be performed
reliably to avoid the external force of cables from transmitting to the terminals. Improper connection
or fastness may lead to burning or fire accidents.
• There must be the ground connection according to the criterion. Unreliable grounding may
cause electrical shocks. Do not connect the grounding line to the gas pipe, water pipe,
lightening rod and telephone line.
• Only copper wire can be used. Breaker for electric leakage should be provided, or electric shock
may occur.
• The wiring of the mains line is of Y type. The power plug L should be connected to the live wire and
plug N connected to null wire while
auxiliary electrically heating function, the live wire and the null wire should not be misconnected, or
the surface of electrical heating body will be electrified. If the power line is damaged, replace it by
the professional personnel of the manufacturer or service center.
• The power line of indoor units should be arranged according to the installation instruction of indoor
units.
• The electrical wiring should be out of contact with the high-temperature sections of tubing as to
avoid melting the insulating layer of cables, which may cause accidents.
• After connected to the terminal tier, the tubing should be curved into be a U-type elbow and
fastened with the pressing clip.
• Controller wiring and refrigerant tubing can be arranged and fixed together.
• The machine can't be powered on before electrical operation. Maintenance should be done while
the power is shut down.
• Seal the thread hole with heat insulating materials to avoid condensation.
• Signal line and power line are separately independent, which can't share one line. [Note: the power
line, signal line are provided by users. Parameters for power lines are shown as below: 3x1.0-1.5)

mm ; parameters for signal line: 2x0.75-1.25)mm
• 5 butt lines (1.5mm) are equipped in the machine before delivery, which are used in connection
between the valve box and the electrical system of the machine. The detailed connection is
displayed in the circuit diagram.
Supply Wiring Drawing
• Indoor units and outdoor units should be connected to the power source separately. Indoor units
must share one single electrical source, but its capacity and specifications should be calculated.
Indoor & outdoor units should be equipped with the power leakage breaker and the overflow
breaker.
