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 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.
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.
• Is the circulation of air adequate?
• Is the draining smooth?
• Is the heat insulation complete refrigerant and drain piping?
