7.1 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 e
lectrical work, it can lead to shock,
fire, unit and property damage.
• Connect the power cable to the
terminalsand 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 a 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 theindoor 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.
GB-15 7
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.
