1 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.
- The test run is started by pressing the
room temperature checking button and
down timer button for 3 seconds at the
same time.
- To cancel the test run, press any button.
- After completing work, be sure to meas-
ure and record trial run properties, and
store measured data, etc.
- Measuring items are room temperature,
outside temperature, suction tempera-
ture, blow out temperature, wind velocity,
wind volume, voltage, current, presence
of abnormal vibration and noise, operating
pressure, piping temperature, compres-
sive 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

CHECK THE FOLLOWING
ITEMS WHEN INSTALLATION IS
COMPLETE
Thermometer
CAUTION
• For test run, carry out the cooling op-
eration firstly even during heating sea-
son. If heating operation is carried out
firstly, it leads to the trouble of com-
pressor. Then attention must be paid.
• Carry out the test run more than 5
minutes without fail.(Test run will be
cancelled 18 minutes later automati-
