ELECTRICAL SAFETY REQUIREMENTS
1. The power supply must be of rated voltage with
special circuitry for air-conditioning. The
diameter of the power cord must comply with
requirements.
2. Applicable voltage range: the normal operating
range of voltage is 90%~110% of rated
voltage.
3. Never pull the power cord.
4. Ensure safe grounding and a grounding wire
connected with the special grounding system of
the building, installed by professionals. The
mains must be fitted with electrical leakage
protection switch and an air switch with
sufficient capacity (Refer to the following chart).
The air switch must also have a magnetic and a
thermal tripping function to ensure protection
in case of short-circuit and overload.
5. The minimum clearance between air
conditioner and any flammable surface is 1.5m.
Minimum size of earthing cable is 1.0 mm
2
The live wire, neutral wire and earthing wire
inside the power socket must be connected.
Connect these wires correctly and reliably
without short circuit inside. Incorrect
connection might cause fire.
Grounding Requirement
1. As the air-conditioning unit is a Class 1 electrical
appliance, reliable grounding measures must be
taken;
2. The yellow and green cable inside the air
conditioner is for grounding and must not be
used for other purposes or cut. Do not tighten
with tapping screws; this could cause
electrocution;
3. The user power supply shall have a reliable
grounding terminal. It is prohibited to connect
the grounding wire to the following items:
1) Water Supply Pipe
2) Gas Pipe
3) Sewage Pipe
4) Other positions that are considered unsafe
professionals.
Other:
1. The connection between the air conditioner
and power cables and the connection between
separate elements shall be in accordance with
the wiring diagram attached on the machine;
2. The model and rating of fuse shall be in
accordance with the stencil on the control or
fuse tube;
3. External static pressure of air conditioner at test
position is 0Mpa;
4. All the electrical work must be done by
qualified personnel according to relative wiring
regulation and this manual;
5. The power supply is type Y connection. If the
supply cord is damaged, it must be replaced by
the manufacturer or its service agent or a
similarly qualified person in order to avoid a
hazard;
6. The rated voltage and the exclusive circuit must
be used.
