Safety Considerations

1. Safety Considerations

Read these SAFETY CONSIDERATIONS carefully before repairing air conditioners and heat pumps. After completing repairs, check if the unit operates properly. All electrical repairs and work must be carried out by qualified personnel in accordance local, state, and national regulations. Follow all instructions that are listed under each hazard sign (DANGER, WARNING, CAUTION, NOTE) as they are important for ensuring safety.

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.

1.1During Repairs

WARNING

Disconnect power before disassembling the equipment for repairs. Working on the equipment that is connected to a power supply could 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.

Prior to disconnecting the suction or discharge pipe of the compressor at welded sections, pump-down the refrigerant gas completely. If there is gas or oil remaining inside the compressor, the refrigerant gas or oil can discharge when the pump is being disconnected and it could cause an injury.

If refrigerant gas is discharges during repair work, do not touch the discharged refrigerant gas. The refrigerant gas could cause frostbites.

If refrigerant gas leaks during repair or service, ventilate the area immediately. Refrigerant gas could produce toxic gas if it comes into contact with flames.

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 charge capacitor could cause an electrical shock.

Do not start or stop the air conditioner or heat pump operation by plugging or unplugging the power cord. Plugging or unplugging he power cord to operate or disconnect the equipment could cause an electrical shock or fire.

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

Use only pipes, flare nuts, tools, and the 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 could cause a serious accident or an equipment failure.

If the installation platform or frame has corroded, have it replaced. A corroded platform or frame could cause electrical shock or fire.

When relocating equipment, make sure that the new installation site has sufficient strength to withstand the weight of the equipment. If the installation site does not have sufficient strength and if the installation work is not conducted securely, the equipment could fall and cause injury.

When relocating equipment, keep the refrigerant circuit free from all substances other than the specified refrigerant, such as air. Any presence of air or other foreign substance in the refrigerant circuit could cause an abnormal pressure rise or rupture, resulting in injury.

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 could fall and cause injury.

CAUTION

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.

Equipment must be grounded when carrying out repairs 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 may cause injury.

Do not tilt the unit when removing it. The condensate water inside the unit may spill and wet furniture and floors.

Safety Considerations

vii

Safety Considerations

Do not touch the refrigerant pipes during and immediately after operation for any repair work as the refrigerant pipes may be hot or cold, depending on the condition of the refrigerant flowing through the refrigerant piping, compressor, and other refrigerant cycle parts. Your hands may suffer burns

All welding and cutting operations must be done in a well-ventilated place. Welding and cutting operations done in an enclosed room may cause deficiency in oxygen in the enclosed room.

Dismantling of the unit, disposal of refrigerant, oil, and additional parts, should be done in accordance with the relevant local, state, and national regulations.

1.2After Repairs

WARNING

Use an exclusive power circuit for the equipment. Insufficient circuit amperage capacity could cause an electrical shock or fire.

Use specified cable to connect indoor and outdoor units. Make the connections securely, and route the cable properly so that there is no force pulling the cable a the connection terminals. Improper connections could cause excessive heat generation or fire.

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

Do not damage or modify the power cable. Damaged or modified power cables could cause an electrical shock or fire. Placing heavy items on the power cable could damage the cable.

Do not charge air or gas other than the specified refrigerant to the refrigerant system. If air enters the refrigerant system, it could cause excessive high pressure resulting in equipment damage and injury.

If refrigerant gas leaks, locate the leaking point and repair it before charging refrigerant. After charging the refrigerant, check for refrigerant leaks. If the leaking pint cannot be located and the repair work must be stopped, perform a pump-down. Close the service valve to prevent the refrigerant gas from leaking into the room. the refrigerant gas itself is harmless, but it could generate toxic gases if it comes into contact with flames.

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, consult with a doctor immediately.

1.3Inspections after Repairs

WARNING

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 could cause electrical shock or fire.

If the power cable and lead wires have scratches or are deteriorated, replace them. Damaged cable and wires could cause an electrical shock, excessive heat generation, or fire.

Do not use a joined power cable or extension cable, or share the same power outlet with other electrical appliances as it could cause an electrical shock, excessive heat generation, or fire.

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

Measure the insulation resistance after the repair.

The resistance must be 1M or higher. Faulty insulation could cause an electrical shock.

CAUTION

Check the drainage of the indoor unit after the repair. Faulty drainage may cause the water to enter the room resulting in wet floors and furniture.

1.4Safety for Users

DANGER

Never attempt to modify the equipment. Doing so will cause electrical shock, excessive heat generation, or fire.

WARNING

Never remove the fan guard of the unit while the unit is operating. A fan rotating at high speed without the fan guard is very dangerous.

CAUTION

Before cleaning the unit, stop the operation of the unit by turning the power off or by pulling the power cord out from its socket. Otherwise, an electrical shock or injury may result.

NOTE

Do note wipe the controller operation panel with benzene, thinner, chemical dust cloths, or similar. The panel may get discolored or the coating can peel off. if it is extremely dirty, soak a cloth in a waterdiluted neutral detergent, squeeze it well, and wipe the panel clean. Then wipe it with another dry cloth.
