Installation instructions
Wiring
●
Turn OFF the main power switch to the indoor unit and the outdoor unit and wait for more than 3 minutes before
electrical wiring work or a periodical check is performed.
●
Check to ensure that the indoor fan and the outdoor fan have stopped before electrical wiring work or a periodical check
is performed.
●
Protect the wires, electrical parts, etc. from rats or other small animals. If not protected, rats may gnaw at unprotected
parts and at the worst, a fire will occur.
Avoid the wiring from touching the refrigerant pipes, plate edges and electrical parts inside the unit.
●
If not do, the wires will be damaged and at the worst, a fire will occur.
●
Install an ELB (Electric Leakage Break) in the power source.
If ELB is not used, it will cause electric shock or fire at the worst.
●
This unit uses an inverter, which means that it must be used an earth leak detector capable handing harmonics in order
to prevent malfunctioning of the earth leak detector itself.
●
Do not use intermediate connection wires, stranded wires(see <Attentions when Connect the power supply wiring>),
extension cables or control line connection, because the use of these wires may cause fever, electric shock or fire.
●
The tightening torque of each screw shall be as follows.
M4: 1.0 to 1.3 N·m
M5: 2.0 to 2.5 N·m
M6: 4.0 to 5.0 N·m
M8: 9.0 to 11.0 N·m
M10: 18.0 to 23.0 N·m
Keep the above tightening torque when wiring work.
●
With tape material along the wire wrapped, sealed wiring holes, prevent the condensed water and insects.
●
Tightly secure the power source wiring using the cord clamp inside the unit.
NOTE: Fix the rubber bushes with adhesive when conduit tubes to the outdoor unit are not used.
General Check
(1) Make sure that the field-selected electrical components (main power switches, circuit breakers, wires, conduit connectors and
wire terminals) have been properly selected according to the electrical data.
Make sure that the components comply with National Electrical Code (NEC).
(2) Check to ensure that the voltage of power supply is within +10% of nominal voltage and earth phase is contained in the power
supply wires. If not, electrical parts will be damaged.
(3) Check to ensure that the capacity of power supply is enough.
If not, the compressor will not be able to operate cause of voltage drop abnormally at starting.
(4) Check to ensure that the earth wire is connected.
(5) Install a main switch, multi-pole main switch with a space of 3.5mm or more, single phase main switch with a space of 3.0mm
or more between each phase. Please use the special three-phase power switch for 3-Phase product.
(6) Check to ensure that the electrical resistance is more than 2MΩ, by measuring the resistance between ground and the
terminal of the electrical parts. If not, do not operate the system until the electrical leakage is found and repaired.
