Safety Precautions

Service Manual 5

Do not touch electric leakage circuit breaker or switch with wet hands.

• It may cause electric shock.

Install the product in an insulated space.

•

If the product is installed outside of insulating layer(surface), it may cause a dew formation inside main body, electric shock, and dropping of condensed water.

Do not install in oily place such as kitchen and factory.

• It may cause breakdown due to oils stained to filter or electric heat exchanger.

Do not install in humid place such as bathroom.

• It may cause electric shock and breakdown.

Switch the power off during cleaning.

• It may cause fire and electric shock.

Do not connect grounding line to window frame (chassis) and tap.

• It has a danger of electric shock.

Do not carry the product alone.

• Otherwise, it may cause physical damage.

Do not use for special purposes and places including animals and plants, sensitive equipment, and art pieces.

• Otherwise, it may cause physical damage.

Do not use strong detergent such as wax or thinner in case of cleaning, instead use soft cloth.

• It ruins external appearance due to discoloration or scratches on the product.

Clean filter and heat exchanger regularly with your gloves on.

• With a large quantity of dust in the product, the effect of ventilation may be reduced. (it may not well ventilated)
