Toshiba HWS-455H-E Installation Manual page 6

WARNING
• Installation work must be requested from the supplying retail dealership. Self-
installation may cause water leakage, electrical shock, or fi re as a result of
improper installation.
• Specifi ed 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
specifi ed pipe parts, and ensure correct installation, otherwise damage and/or
injury may be caused. At the same time, water leakage, electrical shock, and fi re
may occur.
• Be sure to install the unit in a place which can suffi ciently 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 qualifi ed supplying retail dealership
in accordance with the code governing such installation work, internal wiring
regulations, and the manual. A dedicated circuit and the rated voltage must be
used. Insuffi cient power supply or improper installation may cause electrical
shock or fi re.
• Use a cabtyre cable to connect wires in the hydro/outdoor units. Midway
connection, stranded wire, and single-wire connections are not allowed.
Improper connection or fi xing may cause a fi re.
• Wiring between the hydro unit and outdoor units must be well shaped so that
the cover can be fi rmly placed. Improper cover installation may cause increased
heat, fi re, or electrical shock at the terminal area.
• Be sure to use only approved accessories or the specifi ed parts. Failure to do so
may cause the unit to fall, water leakage, fi re 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 fi re 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 fl ammable gas may leak. If there is any gas leakage
or accumulation around the unit, it can cause a fi re.
• 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 fi re.
