Toshiba RAV-GM901BTP-E Installation Manual page 5

Selection of installation location
• When the air conditioner is installed 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.
• Do not install in a location where flammable gas leaks are
possible. If the gas leak and accumulate around the unit, it may
ignite and cause a fire.
• To transport the air conditioner, wear shoes with additional
protective toe caps.
• To transport the air conditioner, do not take hold of the bands
around the packing carton. You may injure yourself if the bands
should break.
• Install the indoor unit at least 2.5 m above the floor level since
otherwise the users may injure themselves or receive electric
shocks if they poke their fingers or other objects into the indoor
unit while the air conditioner is running.
• Do not place any combustion appliance in a place where it is
directly exposed to the wind of air conditioner, otherwise it may
cause imperfect combustion.

Installation
• When the indoor unit is to be suspended, the designated hanging
bolts (M10 or W3/8) and nuts (M10 or W3/8) must be used.
• Install the air conditioner securely in a location where the base
can sustain the weight adequately. If the strength is not enough,
the unit may fall down resulting in injury.
• Follow the instructions in the Installation Manual to install the
air conditioner. Failure to follow these instructions may cause
the product to fall down or topple over or give rise to noise,
vibration, water leakage or other trouble.
• Carry out the specified installation work to guard against the
possibility of high winds and earthquake. If the air conditioner is
not installed appropriately, a unit may topple over or fall down,
causing an accident.
• If refrigerant gas has leaked during the installation work,
ventilate the room immediately. If the leaked refrigerant gas
comes in contact with fire, noxious gas may generate.
• Use forklift to carry in the air conditioner units and use winch or
hoist at installation of them.
• Suction duct length must be longer than 850 mm.
• Helmet must be worn to protect your head from falling objects.
Especially, when you work under an inspection opening, helmet
must be worn to protect your head from falling objects from the
opening.
Refrigerant piping
• Install the refrigerant pipe securely during the installation
work before operating the air conditioner. If the compressor
is operated with the valve open and without refrigerant pipe,
the compressor sucks air and the refrigeration cycles is over
pressurized, which may cause an injury.
• Tighten the flare nut with a torque wrench in the specified
manner. Excessive tighten of the flare nut may cause a crack in
the flare nut after a long period, which may result in refrigerant
leakage.
• After the installation work, confirm that refrigerant gas does not
leak. If refrigerant gas leaks into the room and flows near a fire
source, such as a cooking range, noxious gas may be generated.
