INSTALLATION OF DECORATIVE PANEL(ACCESSORY)
28
CAUTION
!
Install certainly the decorative panel.
Cool air leakage causes sweating.
⇨ Water drops fall.
Good example
Decorative panel
Fit the insulator (this part) and
be careful for cool air leakage
Bad example
Cool Air
Leakage
(not good)
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 volume,
voltage, current, presence of abnormal vibra-
tion and noise, operating pressure, piping tem-
perature, compressive pressure.
- As to the structure and appearance, check fol-
lowing 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).
