11. PRECAUTIONS REGARDING TEST RUN
Check Before Test Run
Outdoor unit Check that the insulation resistant value is more than 1MΩ.
●
Use the 500 V mega-testers to measure the insulation.
Check point : between power supply terminal block (L1, L2, L3, or L, N) to earth.
Do not use the mega-tester for any other circuit except for voltage of 220-230-240V~ or 380-400-415V 3N~.
Power supply cable Is the wire set up and connected as described in the instructions? Check for any phase sequence.
●
Indoor/outdoor connection wire Are the wire connection's screws loose?
●
Earth wire Is the open and close device / leakage breaker installed?
●
Is the power supply cable's thickness and length appropriately measured as described in the instructions?
●
Is it earthed (grounded)?
●
Are the wire connections for the indoor/outdoor units connected as described in the instructions? Are there any looped wires?
●
Was the "N-phase" surely connected when connecting the power supply wire on the three-phase model?
●
If N-phase is not connected, only the fan may repeat turning ON/OFF without the compressor operating. In that case, check if there is
any problem with N-phase connection.
Refrigerant tube Is the tubing installed as described in the instructions?
●
Are the tubes sizes appropriate?
●
Does the tube's length adhere to the specifications?
●
Is the branch tube slant being appropriately done as described in the instructions?
●
Was vacuum removal sufficiently carried out?
●
Was the leak tightness test carried out with nitrogen gas? Use the testing pressure of 4.15 MPa.
●
Is the tubing insulation material appropriately installed? (Insulation material is necessary for both gas and liquid tubing.)
●
Is the 3-way valve for the liquid tube and gas tube open?
●
Always be sure to use a properly insulated tool to operate the short-circuit pin on the circuit board. (Do not use your finger.)
●
Never switch the power supply ON until the installation has completed.
●
Supply electrical current through all indoor units and check the voltage.
●
Supply electrical current through all the outdoor units and check each inter-phase voltage.
●
Before the test run, ensure to check that the 3-way valve is open. Operating while the valve is closed causes the compressor to fail.

Test Run Procedure
If there are duplicated system addresses, or if the settings for the Nos. of the indoor units are not consistent,
●
an alarm will occur and the system will not start.
Switch the power supply ON both indoor and outdoor unit.
●
Short-circuit CHK pin on the outdoor main PCB.
●
Do not remove CHK pin until test run is completed.
Removing CHK pin stops test run.
Short-circuit RUN pin on the outdoor main PCB for one second or longer.
●
Factory setting is cooling operation mode and cooling operation test run starts.
If heating operation starts, short-circuit both right side and centre of the MODE pin (centre and COOL)
continuously.
Ensure to conduct a test run. In addition, be sure to run the cooling operation test run for at least 20 minutes
●
before starting the heating operation test run.
To conduct heating operation test run, short-circuit left side and centre of the MODE pin (centre and HEAT)
●
continuously.
Removing CHK pin's and MODE pin's short-circuit stops test run.
●
For the test run using remote controller, please see installation instructions included with the remote controller.
●
Caution for Pump Down
Pump down means refrigerant gas in the system is returned to the outdoor unit. Pump down is used when the unit is
to be moved, or before servicing the refrigerant circuit.
How to perform Pump-Down (Refrigerant recovery) properly
(1) Stop operation of the unit (cooling, heating etc.).
(2) Connect the pressure gauge to the service port of the gas tubing valve.
U-250
(3) Short-circuit the "PUMPDOWN" pin on an outdoor unit control PCB (CR) for more than 1 second to release.
Pump-Down begins and the unit starts operating.
S-1014 S-1014 ●
During Pump-Down, LED1 blinks and LED2 is lit on an outdoor unit control PCB (CR).
●
"CHK" blinks on the remote controller.
●
(4) Fully close the liquid tubing valve 2-3 minutes later.
The Pump-Down will begin.
(5) When the pressure gauge drops to 0.1-0.2MPa, close the gas tubing valve tightly and short-circuit the
"PUMPDOWN" pin for more than 1 second to release. That is the end of Pump-Down.
When running for more than 10 minutes, it stops even if the Pump-Down is not completed. Check the blocked
●
U-250
state of the liquid tubing valve.
lt also stops when the "PUMPDOWN" pin is short-circuited during the operation.
●
S-6071 S-6071 S-6071
* For compressor protection, do not operate to the point where the unit wiring side reaches negative pressure.
Note : In the case that inter-unit wiring is 30m or longer, you cannot pump-down. (lt may trigger the operation of the overload protection device.)
In this case, perform pump-down with pump-down device.
12. CHECKS AFTER INSTALLATION HAVE COMPLETED
Check the following items after completing installation.
●
 Is there a short circuit with the intake air flow?
 Is the insulation secure? (Refrigerant tubing)
 Are there any errors with the wiring?
 Are the terminal screws loose? Tightening torque (Unit: N•m {kgf•cm})
M4...1.57~1.96{16~20}, M5...1.96~2.45{20~25}
 Is the drain water flowing smoothly?
 Is the insulation material properly installed?
 Is the earth wire securely connected?
 Is the front panel and the indoor unit air conditioner firmly fixed and was the installation completed without any leakage from the refrigerant?
 Are the indoor and outdoor units secured firmly installed with bolts at secured locations?
