Wiring
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.
• 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 outlet
cannot handle the load or there is a defect
in the wiring, it can lead to shock, fire, and
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 power 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.
If the supply cord is damaged, it must be
•
replaced by the manufacturer, its service
agent or similarly qualified persons in order
to avoid a hazard.
CAUTION
•
Connect the out door 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.
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.
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
before preparing it for connection. Be sure
to use H07RN-F cables.
