Safety precautions
WARNING
• Disconnect the power supply before working on the unit.
• All wiring must be performed according to local and
national regulations.
• Wiring must be done by a qualified technician.
Improper connections may cause electrical
malfunction, injury, or fire.
•
Do not
connect another appliance into the same
circuit. If the unit cannot handle the load or there is
a defect in the wiring, it can lead to shock, fire, and
property damage.
• Connect the power cable to the terminals and fasten it
with a clamp. An insecure connection may cause fire.
• Make sure that all wiring is done correctly and the
control board cover is properly installed. Failure to do
so can cause overheating at the connection points,
fire, and electrical shock.
• Ensure that main power supply connection is made
through a switch that disconnects all poles, with
contact gap of at least 3mm.
CAUTION
• Connect the outdoor wires before connecting the
indoor wires.
• Make sure you ground the unit. The grounding wire
should be located away from gas pipes, water pipes,
lightning rods, telephone wires or other grounding
wires. Improper grounding may cause electrical shock.
•
Do not
connect the unit to the power source until all
wiring and piping is completed.
• Make sure that you
do not
cross your electrical wiring
with your signal wiring. This may cause distortion and
interference.
To prevent distortion when the compressor starts (you can find
the unit’s power information on the rating sticker):
• No other equipment should be connected to the same
power circuit.
• To prevent distortion when the compressor starts (you can
find the unit’s power information on the rating sticker), no
other equipment should be connected to the same
power circuit.
Take note of fuse specifications
The air conditioner’s printed circuit board (PCB) is
designed with a fuse that provides overcurrent protection.
The specifications of the fuse are printed on the
circuit board; examples of such are T5A/250VAC and
T10A/250VAC.
Outdoor unit wiring
WARNING
Before performing any electrical or wiring work, turn off the
main power to the system.
1. Prepare the cable for connection
a. You must first choose the right cable size. Be sure to
use H07RN-F cables.

b. Using wire strippers, strip the insulation from both
ends of the signal cable to reveal approximately
15cm of wire.
c. Strip the insulation from the ends.
d. Using a wire crimper, crimp u-lugs on the ends.
NOTE:
When connecting the wires, strictly follow the
wiring diagram found inside the electrical box cover.
