Safety Considerations SiUS04-904

vi Safety Considerations

1. SAFETY CONSIDERATIONS

Read these SAFETY CONSIDERATIONS carefully before
performing any repair work. Comply with these safety
symbols without fail.

Meanings of DANGER, WARNING, CAUTION, and NOTE
Symbols:

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.

1.1 Safety Considerations for Repair

DANGER

• If refrigerant gas leaks during repair or service,
ventilate the area immediately. Refrigerant gas may
produce toxic gas if it comes into contact with flames.
Refrigerant gas is heavier than air and replaces
oxygen. In the event of an accident, a massive leak
could lead to oxygen depletion, especially in
basements, and an asphyxiation hazard could occur
leading to serious injury or death.

• Do not start or stop the air conditioner operation by
plugging or unplugging the power cable plug if a
plug is used. Plugging or unplugging the power
cable plug to operate the equipment may cause an
electrical shock or fire.

• Use parts listed in the service parts list and
appropriate tools to conduct repair work. The use of
inappropriate parts or tools may cause an electrical
shock or fire.

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

• 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 charged capacitor
may cause an electrical shock.

• If refrigerant gas is discharged during repair work,
do not touch the discharged refrigerant gas. The
refrigerant gas may cause frostbite.

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

• 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 may cause excessive
heat generation, fire, or electrical shock.

WARNING

• Prior to disconnecting the suction or discharge pipe
from the compressor at the welded section,
pump-down the refrigerant gas completely in a well­ventilated place first. If there is refrigerant gas or oil
remaining inside the compressor, the refrigerant gas or
oil can discharge when the pipe is being disconnected
and it may cause an injury.

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

• Do not mix air or gas other than the specified
refrigerant R410A to the refrigerant system. If air
enters the refrigerant systems, it can cause an
excessive high pressure resulting in equipment
damage and injury.

• When relocating the equipment, check if the new
installation site has sufficient strength to withstand
the weight of the equipment. If the installation site
does not have sufficient strength and the equipment
is not properly secured, the equipment may fall and
cause injury.

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

• When relocating the system, keep the refrigerant
circuit free from substances other than the specified
refrigerant (R-410A) such as air. Any presence of air
or other foreign substance in the refrigerant circuit
can cause an abnormal pressure rise or rupture,
resulting in injury.

• If refrigerant gas leaks, locate the leaking point and
repair it before charging refrigerant. After charging
refrigerant, check for refrigerant leaks. If the leaking
point cannot be located and the repair work must be
stopped, perform a 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 may generate toxic gases if it comes
into contact with flames.

SiUS04-904 Safety Considerations

Safety Considerations vii

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 by splashing water
on it. Washing the unit with water may cause an
electrical shock.

• Ground the unit when repairing equipment 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 can cause injury.

• Let the refrigerant lines cool down before performing
any repair work. Working on the unit when the
refrigerant lines are hot may cause burns.

• All welding and cutting operations must be done in a
well-ventilated place to prevent the accumulation of
toxic fumes or possibly oxygen deficiency to occur.

• Check the grounding and repair it if the equipment is
not properly grounded. Improper grounding may
cause an electrical shock.

• Measure the insulation resistance after the repair.

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

NOTE

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

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

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

1.2 Safety Considerations for Users

DANGER

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

• If the power cable and lead wires have scratches or
have become deteriorated, have them replaced.
Damaged cable and wires may cause an electrical
shock or fire.

• Do not use a joined power cable or an extension
cord, or share the same power outlet with other

electrical appliances as it may cause an electrical
shock or fire.

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

WARNING

• 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 pulling the power cable may damage the
cable.

• 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 may fall and
cause injury. If the installation platform or frame has
corroded, have it replaced. A corroded platform or
frame may cause the unit to fall resulting in injury.

• 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 may cause electrical shock or fire.

CAUTION

• 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, see a
doctor immediately.

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

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

• Do not wipe the controller operation panel with
benzene, thinner, chemical dust cloth, etc. The panel
may get discolored or the coating can peel off. If it is
extremely dirty, soak a cloth in a water-diluted neutral
detergent, squeeze it well, and wipe the panel clean.
Then wipe it with another dry cloth.
