TIPS FOR SAVING ENERGY

ENGLISH

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.

IMPORTANT SAFETY INSTRUCTIONS

ENGLISH

• Indoor/outdoor wiring connections must be secured tightly and the cable should be routed properly

so that there is no force pulling the cable from the connection terminals. Improper or loose
connections can cause heat generation or fire.

• Safely dispose off the packing materials. Like screws, nails, batteries, broken things etc after

installation or svc and then tear away and thraw away the plastic packaging bags. Children may
play with them and cause injury.

• Make sure to check that the power cable plug is not dirty, loose or broken and then only insert the

plug completely. Dirty, loose or broken power plug can cause electric shock or fire.

• In outdoor unit the step-up capacitor supplies high voltage electricity to the electrical components.

Be sure to discharge the capacitor completely before conducting the repair work.
An charged capacitor can cause electrical shock.

• When installing the unit, use the installation kit provided with the product. Otherwise the unit may

fall and cause severe injury.

• Be sure to use only those parts which are listed in the svc parts list. Never attempt to modify the

equipment. The use of inappropriate parts can cause an electrical shock, excessive heat generation
or fire.

• Do not use the product in a tightly closed space for a long time. Perform ventilation regularly.

Oxygen deficiency could occur and hence harm your health.

• Do not open the front grille of the product during operation. (Do not touch the electrostatic filter, if

the unit is so equipped.) There is risk of physical injury, electric shock, or product failure.

• If strange sounds, smell or smoke comes from product.Immediately turn the breaker off or

disconnect the power supply cable. There is risk of electric shock or fire.

• Ventilate the product room from time to time when operating it together with a stove, or heating

element etc. Oxygen deficiency can occur and hence harm your health.

• Turn the main power off and unplug the unit when cleaning or repairing the product. There is risk of

electric shock.

• When the product is not to be used for a long time, disconnect the power supply plug or turn off the

breaker. There is risk of product damage or failure, or unintended operation.

• Take care to ensure that nobody especially kids could step on or fall onto the outdoor unit. This

could result in personal injury and product damage.

• Take care to ensure that power cable could not be pulled out or damaged during operation. There is

risk of fire or electric shock.

• Do not place anything on the power cable. There is risk of fire or electric shock.

• Do not plug or unplug the power supply plug to turn the unit ON/OFF. There is risk of fire or electric

shock.

ENGLISH

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
triggered on while cleaning inner parts of the unit.
