11.6.11 PRECAUTION IN TEST RUN
For test run, refer to the “Precautions in test run” in the outdoor unit installation instructions manual.
Test run is conducted using the wired controller, emergency switch on the infrared receiver or by using the outdoor
units. For the wired controller test run see the instructions below.
TEST RUN
• Switch the power supply to ON for at least 12 hours in advance before the test run.
• First, press the ON/OFF (
) button.
• Next, select the operational modes.
• Then press the TEST RUN button within 1 minute of pressing the ON/OFF (
) button.
• Be sure to run the cooling operation test run for at least 20 minutes before starting the heating
operation test run.
• Press TEST RUN or ON/OFF (
) button again to cancel the test run mode.
NOTE 1
Detaching a connector with electrical current may cause damage to the control board. Ensure to
turn OFF the power supply and wait for at least 5 minutes before performing this operation.
NOTE 2
Do not short the remote control wires. (There is no protective circuit operation.) Normal operation
will commence once the short is solved.
NOTE 3
During the test run; ensure to operate the units in cooling mode prior to operating the units in
heating mode. Caution: Operating the units in heating mode first may cause compressor failure.
NOTE 4
Test run should be performed for a minimum of 20 minutes. (Test run using the remote controller
will change to normal operation after 30 minutes.)
NOTE 5
Use the outdoor unit to cancel the outdoor unit test run and the wired controller to cancel the wired
controller test run. For the test run method using the AUTO button on the infrared receiver, refer to
the “Emergency operation” section in the installation instruction manual for the infrared receiver.
11.6.12 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.
• As to the structure and appearance, check the following items.
Is circulation of air adequate?
Is draining smooth?
Is heat insulation complete
(refrigerant and drain piping)?
Is there any leakage of refrigerant?
Is remote controller switch operated?
Is there any faulty wiring?
Are the terminal screws loosened?
