TEST RUNNING
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
!
• For test run, carry out the cooling
operation firstly even during heating
season. If heating operation is carried out
firstly, it leads to the trouble of
compressor. Then attention must be paid.
• Carry out the test run more than 5
minutes without fail.
(Test run will be cancelled 18 minutes
later automatically)
- To cancel the test run, press any button.
CHECK THE FOLLOWING ITEMS WHEN
INSTALLATION IS COMPLETED
- 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?

Connection of power supply
- Connect the power supply cable to the
independent power supply.
Circuit breaker is required.
- Operate the unit for 15 minutes or more.
Evaluation of the performance
- Measure the temperature of the intake and
discharge air.
- Ensure the difference between the intake
