pump-down and close the service valve to prevent the refrigerant gas from leaking into the room. The refrigerant
gas itself is harmless, but it may generate toxic gases if it comes into contact with flames.
• Do not repair the electrical components with wet hands. Working on the equipment with wet hands may cause an
electrical shock.
• Do not clean the air conditioner or heat pump by splashing water on it. Washing the unit with water may cause an
electrical shock.
• Turn off the power when cleaning the equipment to prevent internal fans that rotate at high speed from starting
suddenly as they can cause injury.
• Let the refrigerant lines cool down before performing any repair work. Working on the unit when the refrigerant
lines are hot may cause burns.
• All welding and cutting operations must be done in a well-ventilated place to prevent the accumulation of toxic
fumes or possibly oxygen deficiency to occur.
• Check the grounding before repairing equipment in a humid or wet place to avoid electrical shocks. Improper
grounding may cause an electrical shock.
• Measure the insulation resistance after the repair. The resistance must be 1M
cause an electrical shock.
• Check the drainage of the indoor unit after finishing repair work. Faulty drainage may cause water to enter the
room resulting in wet floors and furniture.
• Do not tilt the unit when removing it. The water inside the unit may spill resulting in wet floors and furniture.
• Dismantling of the unit, disposal of the refrigerant, oil, and additional parts, should be done in accordance with the
relevant local, state, and national regulations.

Safety Considerations for Users

• Never attempt to modify the equipment. Doing so can cause electrical shock, excessive heat generation, or fire.
• If the power cable and lead wires have scratches or have become deteriorated, have them replaced. Damaged
cable and wires may cause an electrical shock or fire.
• Do not use a joined power cable or an extension cord, or share the same power outlet with other electrical
appliances as it may cause an electrical shock or fire.
• Use an exclusive power circuit for the equipment. Insufficient circuit amperage capacity may cause an electrical
shock or fire.
• Do not damage or modify the power cable. Damaged or modified power cables may cause an electrical shock or
fire. Placing heavy items on the power cable or pulling the power cable may damage the cable.
• Check the unit foundation for damage on a continual basis, especially if it has been in use for a long time. If left
in a damaged condition, the unit may fall and cause injury. If the installation platform or frame has corroded, have
it replaced. A corroded platform or frame may cause the unit to fall resulting in injury.
• If the unit has a power cable plug and it is dirty, clean the plug before securely inserting it into a power outlet. If
the plug has a loose connection, tighten it or it may cause electrical shock or fire.
• After replacing the battery in the remote controller, dispose of the old battery to prevent children from swallowing
it. If a child swallows the battery, see a doctor immediately.
• Never remove the fan guard of the unit. A fan rotating at high speed without the fan guard is very dangerous.
• Before cleaning the unit, stop the operation of the unit by turning the power off or by pulling the power cable plug
out from its receptacle. Otherwise an electrical shock or injury may result.
• Do not wipe the controller operation panel with benzene, thinner, chemical dust cloth, etc. The panel may get
discolored or the coating can peel off. If it is extremely dirty, soak a cloth in a water-diluted neutral detergent,
squeeze it well, and wipe the panel clean. Then wipe it with another dry cloth.
