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.
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.
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?
M4......118 N.cm{12 kgf.cm}
M5......196 N.cm{20 kgf.cm}
M6......245 N.cm{25 kgf.cm}
M8......588 N.cm{60 kgf.cm}
- To cancel the test run, press any button.
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)
!
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).
