Selection Of Installation Location; Electrical Wiring - Toshiba MMD-AP0056SPH-E Manual Del Usuario

• When work is performed at heights, use a ladder which complies with the
ISO 14122 standard, and follow the procedure in the ladder's instructions.
Also wear a helmet for use in industry as protective gear to undertake the
work.
• Before cleaning the filter or other parts of the outdoor unit, set the circuit
breaker to OFF without fail, and place a "Work in progress" sign near the
circuit breaker before proceeding with the work.
• Before working at heights, put a sign in place so that no-one will approach
the work location, before proceeding with the work. Parts and other
objects may fall from above, possibly injuring a person below. While
carrying out the work, wear a helmet for protection from falling objects.
• The refrigerant used by this air conditioner is the R410A.
• The air conditioner must be transported in stable condition. If any part of
the product is broken, contact the dealer.
• When the air conditioner must be transported by hand, carry it by two or
more people.
• Do not move or repair any unit by yourself. There is high voltage inside the
unit. You may get electric shock when removing the cover and main unit.

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
• Suction duct length must be longer than 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 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.
• 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.
• The unit can be accessed from the service panel shown in the figure.
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 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.
• 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.

Electrical wiring

• Only a qualified installer (*1) or qualified service person (*1) is allowed to
carry out the electrical work of the air conditioner. Under no circumstances
must this work be done by an unqualified individual since failure to carry
out the work properly may result in electric shocks and/or electrical leaks.
