!
CAUTION
Install certainly the decorative panel.
Cool air leakage causes sweating.
Water drops fall.
Good example
Fit the insulator (this part) and
be careful for cool air leakage
Bad example

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 opera-
tion 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 min-
utes 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, out-
side temperature, suction temperature, blow
out temperature, wind velocity, wind vol-
ume, voltage, current, presence of abnormal
vibration and noise, operating pressure, pip-
ing 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 cord to the inde-
pendent 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
temperature and the discharge one is more
than 8 °C (Cooling) or reversely (Heating).
