Safety Precautions
WARNING
• Be sure to disconnect the power supply
before performing any electrical work.
• All electrical wiring must be in accordance
with all local and national regulations.
• Electrical wiring must be done by a
qualified technician. Improper connections
may lead to electrical malfunction, injury,
and fire.
• An independent circuit and circuit breaker
must be used for this unit. DO NOT power
another appliance through the same circuit
breaker. If the electrical circuit capacity
is not enough, or there is a defect in the
electrical work, it can lead to shock, fire, or
unit and property damage.
• Connect the power cable to the terminals
and fasten it with a clamp. An unsecured
connection may lead to fire.
• Make sure that all wiring is done correctly
and that the control board cover is properly
installed. Failure to do so can cause
overheating at the connection points, fire,
and electrical shock.
• Ensure that if the main supply connection is
made through a switch, that it disconnects
all poles, with a contact gap of a least 3mm
(1/8").
DO NOT use temporary power wiring or
•
an extension cord. Use only hard wiring.
CAUTION
• Connect the outdoor unit wires before
connecting the indoor unit wires.
• Make sure that the unit is grounded. 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 a 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.

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.
