Warning - Toshiba RAS-B10N3KV2-E Service Manual

• Installation work must be requested from the supplying retail dealership or professional vendors. Self-installation may
cause water leakage, electrical shock, or fire as a result of improper installation.
• Specified tools and pipe parts for model R410A are required, and installation work must be done in accordance with
the manual. HFC type refrigerant R410A has 1.6 times more pressure than that of conventional refrigerant (R22).
Use the specified pipe parts, and ensure correct installation, otherwise damage and/or injury may be caused. At the
same time, water leakage, electrical shock, and fire may occur.
• Be sure to install the unit in a place which can sufficiently bear its weight. If the load bearing of the unit is not enough,
or installation of the unit is improper, the unit may fall and result in injury.
• Electrical work must be performed by a qualified elecrical engineer in accordance with the code governing such
installation work, inernal wiring regulations, and the manual. A dedicated circuit and the rated voltage must be used.
Insufficient power supply or improper installation may cause electrical shock or fire.
• Use a cabtyre cable to connect wires in the indoor/outdoor units. Midway connection, stranded wire, and single-wire
connections are not allowed. Improper connection or fixing may cause a fire.
• Wiring between the indoor unit and outdoor units must be well shaped so that the cover can be firmly placed.
Improper cover installation may cause increased heat, fire, or electrical shock at the terminal area.
• 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. It 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 elestrical 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.
- Be sure to close both service valves and stop the compressor before removing the refrigerant pipe. It 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.
• Never modify this unit by removing any of the safety guards.
• 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.
