Electrical Wiring - Airwell AW-CFV09/07-N11 Manual De Usuario E Instalacion

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 should be connected to the ground wire. For the type with 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: 3×(1.0-1.5)mm
parameters for signal line: 2×(0.75-1.25)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.

• 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.
