1.1 Safety Cautions
Cautions and
Warnings
„
Be sure to read the following safety cautions before conducting repair work.
„
The caution items are c lassified into “
Warning
” and “
Caution
”. The “
Warning
” items are
especially important sin ce they can lead to death or serious injury if they are not followed cl osely. The
“
Caution
” items can also lead to serious accidents under some conditions if they are not fol lo wed.
Therefore, be sure to obser ve all the safety caution item s described below.
„
About the pictograms
This symbol indicates an item for which caution mus t be exercised.
The pictogram shows the item to which attention must be paid.
This symbol indicates a prohibited action.
The prohibited item or action is shown i nsi de or near the symbol.
This symbol indicates an action that must be taken, or an instruction.
The instruction is shown inside or near th e symbol.
„
After the repair work is complete, be sure to conduct a test operation to ensure that the equipment
operates normally, and explain the cautions for opera t ing th e product to the customer
1.1.1 Caution in Repa ir
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
shook.
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.
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.
Introduction Si-71A
viii
1.1.2 Cautions Regarding Products after Repair
Caution
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.
Warning
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.
Be sure to install the product correctly be using the provided standard installation frame.
Incorrect use of the installation frame and improper installation can cause the equipment
to fall, resulting in injury.
For integral units only
Be sure to install the product securely in the installation frame mounted on a window
frame.
If the unit is not securely mounted, it can fall and cause injury.
For integral units only
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 on 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.
Si-71A Introduction
ix
1.1.3 Inspection after Repair
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.
Do not mix air or gas other than the specified refrigerant (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.
If a child swallows the coin battery, see a doctor immediately.
Warning
Caution
Installation of a leakage breaker is necessary in some cases depending on the conditions
of the installation site, 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.
Be sure to install the packing and seal on the installation frame properly.
If the packing and seal are not installed properly, water can enter the room and wet the
furniture and floor.
For integral units only
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.

described in the table bel ow :
1.1.5 U si ng Ic on s Lis t
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 unsulation 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 and floor.
