BEFORE PERFORMING ANY
ELECTRICAL WORK, READ
THESE REGULATIONS
1. All wiring must comply with local and
national electrical codes, regulations
and must be installed by a licensed
electrician.
2. All electrical connections must be made
according to the Electrical Connection
Diagram located on the panels of the
indoor and outdoor units.
3. If there is a serious safety issue with the
power supply, stop work immediately.
Explain your reasoning to the client,
and refuse to install the unit until the
safety issue is properly resolved.
4. Power voltage should be within 90-
110% of rated voltage. Insufcient
power supply can cause malfunction,
electrical shock, or re.
5. 5. If connecting power to xed wiring,
install a surge protector and main power
switch with a capacity of 1.5 times the
maximum current of the unit.
6. If connecting power to xed wiring,
a switch or circuit breaker that
disconnects all poles and has a contact
separation of at least 1/8in (3mm) must
be incorporated in the xed wiring.
The qualied technician must use an
approved circuit breaker or switch.
7. Only connect the unit to an individual
branch circuit outlet. Do not connect
another appliance to that outlet.
8. Make sure to properly ground the air
conditioner.
9. Every wire must be rmly connected.
Loose wiring can cause the terminal
to overheat, resulting in product
malfunction and possible re.
10. Do not let wires touch or rest against
refrigerant tubing, the compressor, or
any moving parts within the unit.
11. If the unit has an auxiliary electric
heater, it must be installed at least 1
meter (40in) away from any combustible
materials.
12. To avoid getting an electric shock,
never touch the electrical components
soon after the power supply has been
turned off. After turning off the power,
always wait 10 minutes or more before
you touch the electrical components.
WARNING
BEFORE PERFORMING ANY
ELECTRICAL OR WIRING WORK,
TURN OFF THE MAIN POWER TO
THE SYSTEM.
Step 6: Connect signal cable
The signal cable enables communication
between the indoor and outdoor units. You
must rst choose the right cable size before
preparing it for connection.
Cable Types
● Indoor Power Cable (if applicable):
H05VV-F or H05V2V2-F
● Outdoor Power Cable: H07RN-F
● Signal Cable: H07RN-F
Minimum Cross-Sectional Area of Power
and Signal Cables (For reference)
Rated Current
of Appliance (A)
Nominal Cross-Sectional
Area (mm²)
> 3 and ≤ 6 0.75
> 6 and ≤ 10 1
> 10 and ≤ 16 1.5
> 16 and ≤ 25 2.5
> 25 and ≤ 32 4
> 32 and ≤ 40 6
CHOOSE THE RIGHT CABLE SIZE
The size of the power supply cable,
signal cable, fuse, and switch needed is
determined by the maximum current of the
unit. The maximum current is indicated on
the nameplate located on the side panel of
the unit. Refer to this nameplate to choose
the right cable, fuse, or switch.
WARNING
ALL WIRING MUST BE PERFORMED
STRICTLY IN ACCORDANCE WITH
THE WIRING DIAGRAM LOCATED ON
THE BACK OF THE INDOOR UNITʼS
FRONT PANEL.
