How to connect wiring
Remove the control box lid of the indoor unit.
Remove the cover of the outdoor unit.
Follow the "Wiring diagram label" attached to the indoor unit's
control box lid to wire the outdoor unit, indoor unit and the
remote controller.
Securely fix the wires with a field supplied champ.
Attach the cover of the outdoor unit.
Precautions
1
Observe the notes mentioned below when wiring to the power
supply terminal board.
-
Do not connect wires of different gauge to the same power
supply terminal. (Looseness in the connection may cause
overheating.)
-
When connecting wires of the same gauge, connect them
according to the figure.
Use the specified electric wire. Connect the wire securely to
the terminal. Lock the wire down without applying excessive
force to the terminal. (Tightening torque: 1.31N.m 10%).
-
When attaching the control box lid, make sure not to pinch
any wires.
-
After all wiring connections are done, fill in any gaps in the
casing wiring holes with putty or insulation material (field
supply) thus to prevent small animals or dirt from entering
the unit from outside and causing short circuits in the control
box.
2
Do not connect wires of different gauge to the same grounding
terminal. Looseness in the connection may deteriorate the
protection.
Use only specified wires and tightly connect wires to the terminals.
3
Be careful that wires do not place external stress on the terminals.
Keep wiring in neat order so that they do not obstruct other
equipment such as popping open the service cover. Make sure
the cover closes tight. Incomplete connections could result in
overheating, and in the worst case, electric shock or fire.

TEST OPERATION
Make sure the control box lids are closed on the indoor and outdoor
units.
Refer to ''For the following items, take special care during construction
and check after installation is finished'' on page 4.
After finishing the construction of refrigerant piping, drain piping, and
electric wiring, conduct test operation accordingly to protect the unit.
1
Open the gas side stop valve.
2
Open the liquid side stop valve.
3
Electrify crank case heater for 6 hours.
4
Set to cooling operation with the remote controller and start
operation by pushing ON/OFF button.
5
Check the following points. If there is any malfunction, please
resolve it according to the chapter "Troubleshooting" in the
"Owner's Manual".
The indoor unit
-
Whether the switch on the remote controller works well.
-
Whether the buttons on the remote controller works well.
-
Whether the air flow louver moves normally.
-
Whether the room temperature is adjusted well.
-
Whether the indicator lights normally.
-
Whether the temporary buttons works well.
-
Whether there is vibration or abnormal noise during operation.
- Whether the drainage flows smoothly.
The outdoor unit
-
Whether there is vibration or abnormal noise during operation.
-
Whether the generated wind, noise, or condensed of by the air
conditioner have influenced your neighborhood.
-
Whether any of the refrigerant is leaked.
6
Turn off the main power supply after operation.
A protection feature prevents the air conditioner from being
activated for approximately 3 minutes when it is restarted
immediately after shut off.
