LG AT-Q12GULA0 Installation Manual page 27

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?

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.
INSTALLATION OF DECORATIVE PANEL(ACCESSORY)
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).
! CAUTION
After the confirmation of the above condi-
tions, prepare the wiring as follows:
• Never fail to have an individual power
specialized for the air conditioner. As for
the method of wiring, be guided by the
circuit diagram pasted on the inside of
control box cover.
• Provide a circuit breaker switch
between power source and the unit.
• The screw which fasten the wiring in
the casing of electrical fittings are liable
to come loose from vibrations to which
the unit is subjected during the course
of transportation. Check them and make
sure that they are all tightly fastened. (If
they are loose, it could give rise to burn-
out of the wires.)
• Specification of power source
• Confirm that electrical capacity is suffi-
cient.
• Be sure that the starting voltage is
maintained at more than 90 percent of
the rated voltage marked on the name
plate.
