installation is complete
Precautions in test running
TEST RUNNING
- The initial power supply must provide at
least 90 % of the rated voltage.
Otherwise, the air conditioner should not be
operated.
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).
Thermometer
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
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 completed
(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.
• For test run, carry out the cooling oper-
ation 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)
