Test running
1.PRECAUTIONS IN TEST RUN
•The initial power supply must provide at least 90% of the rated voltage. Otherwise, the air conditioner should not be operated.
Caution
Carry out the test run more than 5 minutes without fail. (Test run will be cancelled 18 minutes later automatically)
•The test run is started by pressing the down room temperature checking button and ON/OFF button for 3 seconds at the same time.
•To cancel the test run, press ON/OFF button.
CHECK THE FOLLOWING ITEMS WHEN INSTALLATION IS COMPLETE
•After completing work, be sure to measure and record trial run properties, and store measured data, etc.
•Measuring items are room temperature, outside temperature, suction temperature, blow out temperature, wind velocity, wind volume, voltage, current, presence of abnormal vibration and noise, operating pressure, piping temperature, compressive pressure.
•As to the structure and appearance, check following items.
Is the circulation of air adequate?
Is the draining smooth?
Is the heat insulation complete (refrigerant and drain piping)?
Is there any leakage of refrigerant?
Is the remote controller switch operated?
Is there any faulty wiring?
Are not terminal screws loosened?

2.Connection of power supply
1.Connect the power supply cord to the independent power supply.
• Circuit breaker is required.
2.Operate the unit for fifteen minutes or more.
3.Evaluation of the performance
1.Measure the temperature of the intake and discharge air.
2.Ensure the difference between the intake temperature and the discharge one is more than 8°C(46.4°F) (Cooling) or reversely (Heating).
