Page 5 KSSSI116

Precautions:

Warning:

Be sure to disconnect the power cable plug from the plug socket before

disassembling the equipment for a repair.

Working on the equipment that is connected to a power supply can cause an

electrical shock.

If it is necessary to supply power to the equipment to conduct the repair or

inspecting the circuits, do not touch any electrically charged sections of the

equipment.

If the refrigerant gas discharges during the repair work, do not touch the

discharging refrigerant gas.

The refrigerant gas can cause frostbite.

When disconnecting the suction or discharge pipe of the compressor at the

welded section, release the refrigerant gas completely at a well-ventilated

place first.

If there is a gas remaining inside the compressor, the refrigerant gas or

refrigerating machine oil discharges when the pipe is disconnected, and it can

cause injury.

If the refrigerant gas leaks during the repair work, ventilate the area. The

refrigerant gas can generate toxic gases when it contacts flames.

The step-up capacitor supplies high-voltage electricity to the electrical

components of the outdoor unit.

Be sure to discharge the capacitor completely before conducting repair work.

A charged capacitor can cause an electrical shock.

Page 6 KSSSI116

Warning:

Do not start or stop the air conditioner operation by plugging or unplugging the

power cable plug.

Plugging or unplugging the power cable plug to operate the equipment can

cause an electrical shock or fire.

Do not repair the electrical components with wet hands.

Working on the equipment with wet hands can cause an electrical shock.

Do not clean the air conditioner by splashing water.

Washing the unit with water can cause an electrical shock.

Be sure to provide the grounding when repairing the equipment in a humid or

wet place, to avoid electrical shocks.

Be sure to turn off the power switch and unplug the power cable when cleaning

the equipment.

The internal fan rotates at a high speed, and cause injury.

Do not tilt the unit when removing it.

The water inside the unit can spill and wet the furniture and floor.

Be sure to check that the refrigerating cycle section has cooled down

sufficiently before conducting repair work.

Working on the unit when the refrigerating cycle section is hot can cause burns.

Use the welder in a well-ventilated place.

Using the welder in an enclosed room can cause oxygen deficiency.

Caution:

Be sure to use parts listed in the service parts list of the applicable model and

appropriate tools to conduct repair work. Never attempt to modify the

equipment.

The use of inappropriate parts or tools can cause an electrical shock,

excessive heat generation or fire.

When relocating the 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 can fall and cause injury.

Page 7 KSSSI116

Warning:

Incorrect use of the installation frame and improper installation can cause the

equipment to fall, resulting in injury.

If the unit is not securely mounted, it can fall and cause injury.

Be sure to use an exclusive power circuit for the equipment, and follow the

technical standards related to the electrical equipment, the internal wiring

regulations and the instruction manual for installation when conducting

electrical work.

Insufficient power circuit capacity and improper electrical work can cause an

electrical shock or fire.

Be sure to use the specified cable to connect between the indoor and outdoor

units. Make the connections securely and route the cable properly so that there

is no force pulling the cable at the connection terminals.

Improper connections can cause excessive heat generation or fire.

When connecting the cable between the indoor and outdoor units, make sure

that the terminal cover does not lift off or dismount because of the cable.

If the cover is not mounted properly, the terminal connection section can cause

an electrical shock, excessive heat generation or fire.

Do not damage or modify the power cable.

Damaged or modified power cable can cause an electrical shock or fire.

Placing heavy items on the power cable, and heating or pulling the power cable

can damage the cable.

Page 8 KSSSI116

Warning:

Do not mix air or gas other than the specified refrigerant (R-410A / R22) in the

refrigerant system.

If air enters the refrigerating system, an excessively high pressure results,

causing equipment damage and injury.

If the refrigerant gas leaks, be sure to locate the leak and repair it before

charging the refrigerant. After charging refrigerant, make sure that there is no

refrigerant leak.

If the leak cannot be located and the repair work must be stopped, be sure to

perform 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 can

generate toxic gases when it contacts flames, such as fan and other heaters,

stoves and ranges.

When replacing the coin battery in the remote controller, be sure to disposed

of the old battery to prevent children from swallowing it.

Caution:

Installation of a leakage breaker is necessary to prevent electrical shocks.

Do not install the equipment in a place where there is a possibility of

combustible gas leaks.

If a combustible gas leaks and remains around the unit, it can cause a fire.

If the packing and seal are not installed properly, water can enter the room and

wet the furniture and floor.

Page 9 KSSSI116

Warning:

Check to make sure that the power cable plug is not dirty or loose, then insert

the plug into a power outlet all the way.

If the plug has dust or loose connection, it can cause an electrical shock or fire.

If the power cable and lead wires have scratches or deteriorated, be sure to

replace them.

Damaged cable and wires can 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, since it can cause an electrical shock,

excessive heat generation or fire.

Caution:

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 can cause excessive heat generation,

fire or an electrical shock.

If the installation platform or frame has corroded, replace it.

Corroded installation platform or frame can cause the unit to fall, resulting in

injury.

Check the grounding, and repair it if the equipment is not properly grounded.

Improper grounding can cause an electrical shock.

Be sure to measure the insulation resistance after the repair, and make sure

that the resistance is 1 Mohm or higher.

Faulty insulation can cause an electrical shock.

Be sure to check the drainage of the indoor unit after the repair.

Faulty drainage can cause the water to enter the room and wet the furniture.
