TEST RUNNING
ENGLISH
- The initial power supply must provide at least 90% of the rated voltage.
Otherwise, the air conditioner should not be operated.
- The test run is started by pressing the room temperature checking button and down timer but-
ton for 3 seconds at the same time.
- 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, voltage, current, presence of abnormal vibration and
noise, operating pressure, piping temperature, compressive pressure.
- As to the structure and appearance, check following items.
- Connect the power supply cord to the independent power supply.
Circuit breaker is required.
- Operate the unit for fifteen minutes or more.
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)
