discharged refrigerant gas.
Refrigerant gas may cause frostbite.
When disconnecting the suction or discharge pipe of the
compressor at the welded section, evacuate the refrigerant gas
completely at a well-ventilated place first.
If there is gas remaining inside the compressor, the refrigerant gas or
refrigerating machine oil discharges when the pipe is disconnected, and it
may cause injury.
If refrigerant gas leaks during repair work, ventilate the area.
Refrigerant gas may generate toxic gases when it contacts flames.
2 Introduction
SiUS121827E Safety Cautions
Caution
Warning
Be sure to discharge the capacitor completely before conducting
repair work.
The step-up capacitor supplies high-voltage electricity to the electrical
components of the outdoor unit.
A charged capacitor may cause an electrical shock.
Do not turn the air conditioner on or off by plugging in or
unplugging the power cable.
Plugging in or unplugging the power cable to operate the equipment may
cause an electrical shock or fire.
Be sure to wear a safety helmet, gloves, and a safety belt when
working in a high place (more than 2 m (6.5 ft)).
Insufficient safety measures may cause a fall.
In case of R-32 / R-410A refrigerant models, be sure to use pipes,
flare nuts and tools intended for the exclusive use with the R-32 / R410A refrigerant.
The use of materials for R-22 refrigerant models may cause a serious
accident, such as a damage of refrigerant cycle or equipment failure.
Do not mix air or gas other than the specified refrigerant (R-32 / R410A / R-22) in the refrigerant system.
If air enters the refrigerant system, an excessively high pressure results,
causing equipment damage and injury.
Do not repair electrical components with wet hands.
Working on the equipment with wet hands may cause an electrical shock.
Do not clean the air conditioner with water.
Washing the unit with water may cause an electrical shock.
Be sure to provide an earth / 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 may cause injury.
Be sure to conduct repair work with appropriate tools.
The use of inappropriate tools may cause injury.
Introduction 3
Safety Cautions SiUS121827E
Caution
Warning
Be sure to check that the refrigerating cycle section has cooled
down enough before conducting repair work.
Working on the unit when the refrigerating cycle section is hot may cause
burns.
Conduct welding work in a well-ventilated place.
Using the welder in an enclosed room may cause oxygen deficiency.
1.2 Warnings and Cautions Regarding Safety of Users
Do not store the equipment in a room with fire sources (e.g., naked
flames, gas appliances, electric heaters).
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 may cause an electrical shock,
excessive heat generation or fire.
If the power cable and lead wires are scratched or have deteriorated,
be sure to replace them.
Damaged cable and wires may 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 may
cause an electrical shock, excessive heat generation or fire.
Be sure to use an exclusive power circuit for the equipment, and
follow the local 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 may cause
an electrical shock or fire.
Be sure to use the specified cable for wiring 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 may cause excessive heat generation or fire.
When wiring 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 may
cause an electrical shock, excessive heat generation or fire.
Do not damage or modify the power cable.
Damaged or modified power cables may cause an electrical shock or fire.
Placing heavy items on the power cable, or heating or pulling the power
cable may damage it.
4 Introduction
SiUS121827E Safety Cautions
Caution
Warning
Do not mix air or gas other than the specified refrigerant (R-32 / R410A / R-22) in the refrigerant system.
If air enters the refrigerant system, an excessively high pressure results,
causing equipment damage and injury.
If the refrigerant gas leaks, be sure to locate the leaking point and
repair it before charging the refrigerant. After charging the
refrigerant, make sure that there is no leak.
If the leaking point cannot be located and the repair work must be
stopped, be sure to pump-down, and close the service valve, to prevent
refrigerant gas from leaking into the room. Refrigerant gas itself is
harmless, but it may generate toxic gases when it contacts flames, such
as those from fan type and other heaters, stoves and ranges.
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 or the installation
work is not conducted securely, the equipment may fall and cause injury.
Check to make sure that the power cable plug is not dirty or loose,
then insert the plug into a power outlet securely.
If the plug is dusty or has a loose connection, it may cause an electrical
shock or fire.
When replacing the coin battery in the remote controller, be sure to
dispose of the old battery to prevent children from swallowing it.
If a child swallows the coin battery, see a doctor immediately.
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 combustible gas leaks and remains around the unit, it may cause a fire.
Check to see if parts and wires are mounted and connected
properly, and if connections at the soldered or crimped terminals
are secure.
Improper installation and connections may cause excessive heat
generation, fire or an electrical shock.
If the installation platform or frame has corroded, replace it.
A corroded installation platform or frame may cause the unit to fall,
resulting in injury.
Check the earth / grounding, and repair it if the equipment is not
properly earthed / grounded.
Improper earth / grounding may cause an electrical shock.
Introduction 5
