Wiring Precautions
WARNING
BEFORE PERFORMING ANY ELECTRICAL WORK, READ THESE REGULATIONS.
All wiring must comply with local and
●
national electrical codes, regulations
and must be installed by a licensed
electrician.
All electrical connections must be made
●
according to the Electrical Connection
Diagramlocated on the panels of the
indoor and outdoor units.
If there is a serious safety issue with the
●
power supply, stop work immediately.
Explain your reasoning to the client, and
refuse to install the unit until the safety
issue is properly resolved.
Power voltage should be within 90-110%
●
of rated voltage. Insu cient power
supply can cause malfunction, electrical
shock, or fire.
If connecting power to fixed wiring, a
●
switch or circult breaker that dis-
connects all poles and has a contact
separation of at least 1/8in (3mm) must
be incorporated in the fixed wiring. The
qualified technician must use an
approved circuit breaker or switch.
Only connect the unit to an individual
●
branch circuit. Do not connect another
appliance to that outlet.
Make sure to properly ground the air
●
conditioner.
Every wire must be firmly connected.
●
Loose wiring can cause the terminal to
overheat, resulting in product
malfunction and possible fire.
If connecting power to fixed wiring,
●
install a surge protector and main power
switch with a capacity of 1.5 times the
maximum current of the unit.
Do not let wires touch or rest
●
against refrigerant tubing, the
compressor, or any moving parts
within the unit.
If the unit has an auxiliary electric
●
heater, it must be installed at
least 1 meter (40in) away from
any combustible materials.
To avoid getting an electric
●
shock, never touch the electrical
components soon after the power
supply has been turned o . After
turning o the power, always
wait 10 minutes or more before
you touch the electrical
components.
Make sure that you do not cross
●
your electrical wiring with your
signal wiring. This may cause
distortion, interference.
The unit must be connected to
●
the main outlet. Normally, the
power supply must have a
impedance of 32 ohms.
No other equipment should be
●
connected to the same power
circuit.
Connect the outdoor wires before
●
connecting the indoor wires.
WARNING
BEFORE PERFORMING ANY
ELECTRICAL OR WIRING
WORK, TURN OFF THE MAIN
POWER TO THE SYSTEM.
