1. Introduction
1.1 Safety Cautions
Cautions and
Warnings
"Be sure to read the following safety cautions before conducting repair work.
"The caution items are classified into “ Warning” and “ Caution”. The “ Warning”
items are especially important since they can lead to death or serious injury if they are not
followed closely. The “ Caution” items can also lead to serious accidents under some
conditions if they are not followed. Therefore, be sure to observe all the safety caution items
described below.
"About the pictograms
This symbol indicates an item for which caution must 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 inside or near the symbol.
This symbol indicates an action that must be taken, or an instruction.
The instruction is shown inside or near the 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 operating the product to the
customer
1.1.1 Caution in Repair. 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 Si04-115

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 by 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 or fire.

Si04-115 Introduction

1.1.3 Inspection after Repair
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.
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.

1.1.4 Using Icons
Icons are used to attract the attention of the reader to specific information. The meaning of each
icon is described in the table below:
1.1.5 Using Icons ist
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
and floor.
