TIPS FOR SAVING ENERGY
TIPS FOR SAVING ENERGY
Here are some tips that will help you minimize the power consumption when you use the air
conditioner. You can use your air conditioner more efficiently by referring to the instructions
below:
• Do not cool excessively indoors. This may be harmful for your health and may consume more
electricity.
• Block sunlight with blinds or curtains while you are operating the air conditioner.
• Keep doors or windows closed tightly while you are operating the air conditioner.
• Adjust the direction of the air flow vertically or horizontally to circulate indoor air.
• Speed up the fan to cool or warm indoor air quickly, in a short period of time.
• Open windows regularly for ventilation as the indoor air quality may deteriorate if the air
conditioner is used for many hours.
• Clean the air filter once every 2 weeks. Dust and impurities collected in the air filter may block the
air flow or weaken the cooling / dehumidifying functions.

: Measure the resistance across the power terminals (L,N) using a multi meter.
- Resistance value of a normal connection: 1MΩ or more
- Incorrect wiring resistance value: 500MΩ or less
CAUTION
!
After the confirmation of the above conditions, prepare the wiring as follows:
1) Never fail to have separate power specially for the air conditioner. As for the method of
wiring, follow the circuit diagram pasted on the inside of control box cover.
2) Provide a circuit breaker switch between power source and the unit.
3) 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.)
4) Confirm the Specification of power source
5) Confirm that electrical capacity is sufficient.
6) Be sure that the starting voltage is maintained at more than 90 percent of the rated voltage
marked on the name plate.
7) Confirm that the cable thickness is as specified in the power sources specification.
(Particularly note the relation between cable length and thickness.)
8) Do not install the leakage breaker in a place which is wet or moist.
Water or moist may cause short circuit.
9) The following troubles would be caused by voltage drop-down.
- Vibration of a magnetic switch, damage on the contact point there of, fuse breaking,
disturbance to the normal function of a overload protection device.
- Proper starting power is not given to the compressor.
10) Before applying power to the indoor unit, be sure to check for incorrect wiring of the power
and communication lines.

Airborne Noise Emission
The A-weighted sound pressure emitted by this product is below 70 dB.
** The noise level can vary depending on the site.
The figures quoted are emission level and are not necessarily safe working levels. Whilst there is
a correlation between the emission and exposure levels, this cannot be used reliably to
determine whether or not further precautions are required. Factor that influence the actual level
of exposure of the workforce include the characteristics of the work room and the other sources
of noise, i.e. the number of equipment and other adjacent processes and the length of time for
which an operator exposed to the noise. Also, the permissible exposure level can vary from
country to country. This information, however, will enable the user of the equipment to make a
better evaluation of the hazard and risk.
Limiting concentration
Limiting concentration is the limit of Freon gas concentration where immediate measures can be
taken without hurting human body when refrigerant leaks in the air. The limiting concentration
shall be described in the unit of kg/m
