Selection Of Installation Location - Toshiba Carrier MMD-AP0076BHPUL Manuel D'installation

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 fl ammable gas leaks are
possible. If the gas leak and accumulate around the unit, it may
ignite and cause a fi re.
• 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 8'2" (2.5 m) above the fl oor level
since otherwise the users may injure themselves or receive
electric shocks if they poke their fi ngers 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
Suction duct length must be longer than 33.46" (850 mm).
•
• 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 specifi ed 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 fi re, noxious gas may generate.
Use forklift to carry in the air conditioner units and use winch or
•
hoist at installation of them.
• 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 a injury.
• Tighten the fl are nut with a torque wrench in the specifi ed
manner. Excessive tighten of the fl are nut may cause a crack in
the fl are nut after a long period, which may result in refrigerant
leakage.
• After the installation work, confi rm that refrigerant gas does not
leak. If refrigerant gas leaks into the room and fl ows near a fi re
source, such as a cooking range, noxious gas may be generated.
• When the air conditioner has been installed or relocated,
follow the instructions in the Installation Manual and purge
the air completely so that no gases other than the refrigerant
will be mixed in the refrigerating cycle. Failure to purge the air
completely may cause the air conditioner to malfunction.
• Nitrogen gas must be used for the airtight test.
The charge hose must be connected in such a way that it is not
•
slack.
