TIPS FOR SAVING ENERGY
ENGLISH
Here are some tips that will help you minimize the power consumption when you use the air condi-
tioner. 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 elec-
tricity.
• 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.

BEFORE USE
ENGLISH
About the system
This system of air conditioner can be used for heating/cooling applications.
Preparing for operation
• Contact an installation specialist for installation.
• Use a dedicated circuit.
Usage
• Being exposed to direct airflow for an extended period of time could be hazardous to your health. Do
not expose occupants, pets, or plants to direct airflow for extended periods of time.
• Due to the possibility of oxygen deficiency, ventilate the room when used together with stoves or
other heating devices.
• Do not use this air conditioner for non-specified special purposes (e.g. preserving precision devices,
food, pets, plants, and art objects). Such usage could damage the items.
Cleaning and maintenance
• Do not touch the metal parts of the unit when removing the filter. Injuries can occur when handling
sharp metal edges.
• Do not use water to clean inside the air conditioner. Exposure to water can destroy the insulation,
leading to possible electric shock.
• When cleaning the unit, first make sure that the power and breaker are turned off. The fan rotates at a
very high speed during operation. There is a possibility of injury if the unit’s power is accidentally trig-
gered on while cleaning inner parts of the unit.
Service
For repair and maintenance, contact your authorized service dealer.
Disposal
The unit uses hydrofluorocarbon. Contact your dealer when discarding this unit. It is required by law to
collect, transport and discard the refrigerant in accordance with the “hydrofluorocarbon collection and
destruction” regulations.
