TEST RUNNING

PRECAUTIONS IN TEST RUNNING
- 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.
- To cancel the test run, press any button.
Check the following items when
installation is complete
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, volt-
age, current, presence of abnormal vibration and
noise, operating pressure, piping temperature,
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 independ-
ent power supply.
- Circuit breaker is required.
Operate the unit for fifteen minutes or more.
Evaluation of the performance
