1-481Test Run ProcedureIf there are duplicated system addresses, or if the settings for the Nos. of the indoor units are not consistent, an alarm willoccur 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 forone second or longer.Factory setting is cooling operation mode andcooling operation test run starts.If heating operation starts, short-circuit both rightside and centre of the MODE pin (centre and COOL)continuously.Ensure to conduct a test run. In addition, be sureto run the cooling operation test run for at least 20minutes before starting the heating operation testrun.To conduct heating operation test run, short-circuitleft side and centre of the MODE pin (centre andHEAT) continuously.Removing CHK pin’s and MODE pin's short-circuitstops test run.For the test run using remote control unit, pleasesee installation manual included with the remotecontrol unit.Check Before Test RunContent checkPower supply cableIndoor/outdoorconnection wireEarth wireIs the wire set up and connected as described in the instructions? Check for any phase sequence.Are the wire connection’s screws loose?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)?Check that the insulation resistant value is more than 1 MΩ.Use the 500 V mega-testers to measure the insulation.Do not use the mega-tester for any other circuit except for voltage of 220-240V or 380-415V.Are the wire connections for the indoor/outdoor units connected as described in the instructions? Are thereany 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 pipe Is the piping installed as described in the instructions?Are the pipes sizes appropriate?Does the pipe’s length adhere to the specifications?Is the branch pipe 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 piping insulation material appropriately installed? (Insulation material is necessary for both gas andliquid piping.)Is the 3-way valve for the liquid side and gas side open?Always be sure to use a properly insulated tool to operate the short-circuit pin on the circuit board. (Do not use your fi nger.)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 compressorto fail.1-14. PRECAUTIONS REGARDING TEST RUNRUN pinMODE pin*MODE pin: factory setting is coolingoperation mode.Outdoor main PCBCHK pin
