• 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
result in injury.
• 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 result in an abnormal pressure rise or rupture,
and may result in injury.
• 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 or this could result in injury.
• Let the refrigerant lines cool down before performing
any repair work. Working on the unit when the
refrigerant lines are hot may result in 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
result in an electrical shock.
• Measure the insulation resistance after the repair.
The resistance must be 1M
insulation may result in an electrical shock.
• Check the drainage of the indoor unit after finishing
repair work. Faulty drainage may result in water
entering 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.
1.1.2 Safety Considerations for Users
DANGER
• Never attempt to modify the equipment. Doing so will
result in electrical shock, excessive heat generation or
fire.
WARNING
• If the power cable and lead wires have scratches or
have become deteriorated, have them replaced.
or higher. Faulty
Damaged cable and wires could result in 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 could result in an electrical
shock or fire.
• Use an exclusive power circuit for the equipment.
Insufficient circuit amperage capacity could result in
an electrical shock or fire.
• Never remove the fan guard of the unit. A fan rotating
at high speed without the fan guard is very
dangerous and could result in injury.
• 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 which
may result in injury. If the installation platform or
frame has corroded, have it replaced. A corroded
platform or frame could result in the unit falling and
possible injury.
CAUTION
• Do not damage or modify the power cable. Damaged
or modified power cables may result in an electrical
shock or fire. Placing heavy items on the power
cable or pulling the power cable may result in
damage to the cable.
• 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 result in electrical shock or fire.
• 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.
• 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.
NOTE
• 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.
