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
• 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
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
