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.

- Additional Information : serial number is refer to the barcode on the product.

- Max allowable pressure High side :

4.2 MPa / Low side : 2.4 MPa

- Refrigerant : R32

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.

THE INDOOR UNIT INSTALLATION

ENGLISH

- Select and mark the position for fixing bolts and piping hole.

- Decide the position for fixing bolts slightly tilted to the drain direction after considering the direction of drain hose.

- Drill the hole for anchor bolt on the wall.

CAUTION

• This air-conditioner uses a drain pump.

• Install the unit horizontally using a level gauge.

• During the installation, care should be taken not to damage electric wires.

NOTE

Avoid the following installation location.

1 Such places as restaurants and kitchen

where considerable amount of oil steam and flour is generated. These may cause heat exchange efficiency reduction, or water drops, drain pump mal-function. In these cases, take the following actions;

- Make sure that ventilation fan is enough to cover all noxious gases from this place.

- Ensure enough distance from the cooking room to install the air conditioner in such a place where it may not suck oily steam.

2 Avoid installng air conditioner in such

places where cooking oil or iron powder is generated.

3 Avoid places where inflammable gas is

generated.

4 Avoid place where noxious gas is generat-

ed.

5 Avoid places near high frequency genera-

tors.

Install the unit leaning to a drainage hole side as a figure for easy water drainage.

Position of console Bolt

- A place where the unit will be leveled and that can support the weight of the unit.

- A place where the unit can withstand its vibration.

- A place where service can be easily performed.
