Safety Considerations SiUS091133

1. Safety Considerations

Read these SAFETY CONSIDERAT IONS carefully before perf orming any repair work. Comply with these safety symbols without fail.Meanings of DANGER, WARNING, CAUTION, and NOTE Symbols:

DANGER .............. Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury.

WARNING ............ Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.

CAUTION ............. Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. It

may also be used to alert against unsafe practices.

NOTE .................. Indicates situations that may result in equipment or property-damage accidents only.

1.1 Safety Considerations for Repair

• If refrigerant gas leaks during repair or service, ventilate the area immediately. Refrigerant gas may produce toxic gas if it comes into contact with flames. Refrigerant g as is hea vier than ai r and replaces o xygen. In the event of an accident, a massive leak could lead to oxygen depletion, especially in basements, and an asphyxiation hazard could occur leading to serious injury or death.

• Do not start or stop the air conditioner operation by plugging or unplugging the power cable plug if a plug is used. Plugging or unplugging the power cable plug to operate the equipment may cause an electrical shock or fire.

• Use parts listed in the service parts list and appropriate tools to conduct repair work. The use of inappropriate parts or tools may cause an electrical shock or fire.

• Disconnect power before disassembling the equipment for repairs. Working on the equipment that is connected to the power supply may cause an electric shock. If it is necessary to supply power to the equipment to conduct repairs or to inspect the circuits, do not touch any electrically charged sections of the equipment.

• The step-up capacitor supplies high-voltage electricity to the electrical components of the outdoor unit. Discharge the capacitor completely before conducting repair work. A charged capacitor may cause an electrical shock.

• If refrigerant gas is discharged during repair work, do not touch the discharged refrigerant gas. The refrigerant gas may cause frost bite.

• Use only pipes, flare nuts, tools, and other materials designed specifically for R410A refrigerant systems. Never use tools or materials designed for R22 refrigerant systems on an R410A refrigerant system. Doing so can cause a serious accident or an equipment failure.

• Check to see if the parts and wires are mounted and connected properly, and if the connections at the soldered or crimped terminals are secure. Improper installation and connections may cause excessive heat generation, fire, or electrical shock.

• Prior to disconnecting the suction or discharge pipe from the compressor at the welded section, pump-down the refrigerant gas completely in a well-ventilated place first. If there is refrigerant gas or oil remaining inside the compressor, the refrigerant gas or oil can discharge when the pipe is being disconnected and it may cause an injury.

• Wear a safety helmet, gloves, and a safety belt when working at an elevated height of more than 6.5 ft (2 m). Insufficient safety measures may cause a fall resulting in injury.

• Do not mix air or gas other than the specified refrigerant R410A to the refrigerant system. If air enters the refrigerant systems, it can cause an excessive high pressure resulting in equipment damage and injury.

• When relocating the equipment, check if th e new installation site has sufficient strength to withstand the weight of the equipment. If the installation site does not have sufficient strength and the equipment is not properly secured, the equipment may fall and cause injury.

• Securely fasten the outside unit terminal cover (panel). If the terminal cover/panel is not fastened properly, dust or water may enter the outside unit causing fire or electric shock.

• When relocating the system, keep the refrigerant circuit free from substances other than the specified refrigerant (R410A) such as air. Any presence of air or other foreign substance in the refrigerant circuit can cause an abnormal pressure rise or rupture, resulting in injury.

• If refrigerant gas leaks, locate the leaking point and repair it before charging refrigerant. After charging refrigerant, check for refrigerant leaks. If the leaking point cannot be located and the repair work must be stopped, perform a 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.

viii

SiUS091133 Safety Considerations

• 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 by splashing water on it. Washing the unit with water may cause an electrical shock.

• Ground the unit when repairing equipment in a humid or wet place to avoid electrical shocks.

• 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. W orki ng on the unit when the refrigerant lines are hot may cause burns.

• All welding and cutting operations m ust be done in a well-ventilated p lace to prevent th e accumulation of toxic f umes or possibly oxygen deficiency to occur.

• Check the grounding and repair it if the equipment is not properly grounded. Improper grounding may cause an electrical shock.

• Measure the insulation resistance after the repair. The resistance must be 1M or higher. Faulty insulation may 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.

1.2 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 ma y cause an electrical s hoc k 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 p lu g 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 contro ller, dispose of th e old battery to pre vent ch ildren fr om s wallo wing 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 pan el with be nzene, thinner, chemical du st 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.
