10.4.12. Check the following items when installation is complete
• After completing work, be sure to measure and record trial run properties, and store measuring 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, airtight pressure.
• As to the structure and appearance, check the following items.
M3...69-98 N.cm {7-10 kgf.cm}
M4...157-196 N.cm {16-20 kgf.cm}
M5...196-245 N.cm {20-25 kgf.cm}
10.4.13. Hand over
• Teach the customer the operation and maintenance procedures, using the operation manual (air filter cleaning, temperature
control, etc.)
As to parts to be sold separately
• With regards to installation of the parts sold separately, follow the installation manual which is provided with the parts sold

• First, press the OFF/ON ( ) button.
• Then press the TEST RUN button within 1 minute of pressing the OFF/ON ( ) button.
• Next, select the operation modes.
• The temperature of the indoor unit pipes will be shown on the temperature setting
display. (At the start of the test operation, it may take up to 1 minute for air conditioner
number, switching time and other displays to appear.)
• After operation modes have been selected, stop the compressor for a moment.
• Press the OFF/ON ( ) button of the TEST RUN button once more to cancel test
operation mode.
NOTE 1 These units are equipped with connection error prevention circuits. If the units do not operate, it is possible that the connection
error prevention circuits have operated. In such cases, check that the Indoor/outdoor unit connection wire (connected to
terminals and ) and ) are connected correctly. If they are connected incorrectly, connect them correctly. Normal
operation should then commence.
NOTE 2
Do not short the remote control unit wires to each other. (The protection circuit will be activated and the units will not operate.)
Once the cause of the short is eliminated, normal operation will then be possible.
NOTE 3
When running the units in heating mode during test operation, be sure to run the units in cooling mode first before selecting this
mode. If heating mode is selected first, it may cause problems with operation of the compressor. (Heat pump model only.)
NOTE 4
Test operation should be carried out for a minimum of 5 minutes. (Test operation will be cancelled automatically after 30 minutes.)
NOTE 5
Test operation mode should always be cancelled once test operation itself has been completed.
Is circulation of air adequate?
Is draining smooth?
Is heat insulation complete (refrigerant and drain piping)?
Is there any leakage of refrigerant?
Is remote control switch operated?
Is there any faulty wiring?
Are the terminal screws loosened?
