• Be sure to use only approved accessories or the specified parts.
Failure to do so may cause the unit to fall, water leakage, fire or
electrical shock.
• After the installation work, ensure that there is no leakage of
refrigerant gas. If the refrigerant gas leaks out of the pipe into the
room and is heated by fire or something else from a fan heater,
stove or gas range, it causes generation of poisonous gas.
• Make sure the equipment is properly earthed. Do not connect the
earth wire to a gas pipe, water pipe, lightning conductor, or
telephone earth wire. Improper earth work may be the cause of
electrical shock.
• Do not install the unit where flammable gas may leak. If there is
any gas leakage or accumulation around the unit, it can cause a
fire.
• Do not select a location for installation where there may be
excessive water or humidity, such as a bathroom. Deterioration of
insulation may cause electrical shock or fire.
• Installation work must be performed following the instructions in
this installation manual. Improper installation may cause water
leakage, electrical shock or fire. Check the following items before
operating the unit.
- Be sure that the pipe connection is well placed and there are no
leaks.
- Check that the service valve is open. If the service valve is
closed, it may cause overpressure and result in compressor
damage. At the same time, if there is a leak in the connection
part, it may cause air suction and overpressure, resulting burst or
injury.
• In pump down operations, ensure to perform the following
procedures.
- Do not inject air into the refrigeration cycle.
EN-7
- Be sure to close both service valves and stop the compressor
before removing the refrigerant pipe. If removing the refrigerant
pipe while the compressor is operating with the service valves
opened, it may cause to air absorbed and abnormal high
pressure inside the refrigeration cycle and resulting burst or
injury.
• Do not modify the power cable, connect the cable midway, or use a
multiple outlet extension cable. Doing so may cause contact failure,
insulation failure, or excess current, resulting in fire or electrical
shock.
• Do not use any refrigerant different from the one specified for
complement or replacement. Otherwise, abnormally high pressure
may be generated in the refrigeration cycle, which may result in a
failure or explosion of the product or an injury to your body.
• Be sure to comply with local regulations/codes when running the
wire from the outdoor unit to the indoor unit. (Size of wire and
wiring method etc.)
• Places where iron or other metal dust is present. If iron or other
metal dust adheres to or collects on the interior of the air
conditioner, it may spontaneously combust and start a fire.
• If you detect any damage, do not install the unit. Contact your
supplying dealer immediately.
• Do not install in a place which cannot bear the weight of the unit.
Personal injury and property damage can result if the unit falls.
• When installing the air conditioner in a small room, provide
appropriate measures to ensure that the concentration of
refrigerant leakage occur in the room does not exceed the critical
level. It is not dangerous refrigerant; it has not toxicity or
combustibility. However, a concentration above 0.3 kg/m³ as
criterion still causes suffocation. The volume of refrigerant charged
to the Multi System air conditioner is more than the volume
charged to a conventional individual system.
