Wiring - EAS Electric EFMV2 Series Instruction Manual

Wiring

BEFORE PERFORMING ANY
ELECTRICAL WORK, READ
THESE REGULATIONS
1. All wiring must comply with local and
national electrical codes, regulations and
must be installed by a licensed electrician.
2. All electrical connections must be made
according to the Electrical Connection
Diagram located on the panels of the
indoor and outdoor units.
3. 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.
4. Power voltage should be within 90-110% of
rated voltage. Insufficient power supply can
cause malfunction, electrical shock, or fire.
5. If connecting power to fixed wiring, a
surgeprotector and main power switch
should be installed.
6. If connecting power to fixed wiring, a
switch or circuit breaker that disconnects
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.
7. Only connect the unit to an individual
branch circuit outlet. Do not connect
another appliance to that outlet.
8. Make sure to properly ground the air
conditioner.
9. Every wire must be firmly connected.
Loose wiring can cause the terminal to
overheat, resulting in product malfunction
and possible fire.
10. Do not let wires touch or rest against
refrigerant tubing, the compressor, or any
moving parts within the unit.
11. If the unit has an auxiliary electric heater, it
must be installed at least 1 meter (40in)
away from any combustible materials.
12. To avoid getting an electric shock, never
touch the electrical components soon after
the power supply has been turned off. After
turning off the power, always wait 10
minutes or more before you touch the
electrical components.
13.
Make sure that you do not cross your
electrical wiring with your signal
wiring. This may cause distortion and
interference.
14.
The unit must be connected to the
main outlet. Normally, the power
supply must have a impedance of 32
ohms.
15.
No other equipment should be
connected to the same power circuit.
16.
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.
NOTE ON AIR SWITCH
When the maximum current of the air
conditioner is more than 16A, an air switch
or leakage protection switch with protec-
tive device shall be used (purchased sepa-
rately). When the maximum current of
the air conditioner is less than 16A, the
power cord of air conditioner shall be
equipped with plug (purchased separately).
In North America, the appliance should be
wired according to NEC and CEC require-
ments.
