Safety Precautions
WARNING
• Be sure to disconnect the power supply
before working on the unit.
• All electrical wiring must be done according
to local and national regulations.
• Electrical wiring must be done by a qualified
technician. Improper connections may
cause electrical malfunction, injury and fire.
• An independent circuit and single outlet
must be used for this unit. DO NOT plug
another appliance or charger into the same
outlet. If the electrical circuit capacity is not
enough or there is a defect in the electrical
work, it can lead to shock, fire, unit 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 supply connection is made
through a switch that disconnects all poles,
with contact gap of at least 3mm (0.118").
• DO NOT modify the length of the power
cord or use an extension cord.
CAUTION
• Connect the outdoor wires before
connecting the indoor wires.
• Make sure you ground the unit. The
grounding wire should be away from gas
pipes, water pipes, lightning rods,
telephone or other grounding wires.
Improper grounding may cause electrical
shock.
• DO NOT connect the unit with the power
source until all wiring and piping is
completed.
• Make sure that you do not cross your
electrical wiring with your signal wiring, as
this can cause distortion and interference.
Follow these instructions to prevent distortion
when the compressor starts:
• The unit must be connected to the main
outlet. Normally, the power supply must
have a low output impedance of 32 ohms.
• No other equipment should be connected
to the same power circuit.
• The unit's power information can be found
on the rating sticker on the product.
TAKE NOTE OF FUSE SPECIFICATIONS
The air conditioner's circuit board(PCB) is
designed with a fuse to provide overcurrent
protection. The specifications of the fuse are
printed on the circuit board, such as:
Outdoor unit: T20A/250VAC(for <24000Btu/h
unit), T30A/250VAC(for >24000Btu/h unit)
NOTE: The fuse is made of ceramic.
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
before preparing it for connection. Be sure
to use H07RN-F cables.
