Precautions for safety
Installing, starting up, and servicing air conditioning equipment can be hazardous due to system pressures,
electrical components, and equipment location (roofs, elevated structures, etc.).
Only trained, qualified installers and service mechanics should install, start up, and service this equipment.
Untrained personnel can perform basic maintenance functions such as cleaning indoor unit air filter. All other
operations should be performed by trained service personnel.
Before working on the equipment, observe precautions in the literature and on tags, stickers, and labels attached
to the equipment.
Follow all safety codes. Wear safety glasses and work gloves. Use care in handling, rigging, and setting bulky
equipment.
Read these instructions thoroughly and follow all warnings or cautions included in literature and attached to
the unit. Consult local building codes and National Electrical Code (NEC) for special requirements. Recognize
safety information. This is the safety alert symbol
. When you see this symbol on the unit and in instructions or
manuals, be alert to the potential for personal injury. Understand these signal words: DANGER, WARNING, and
CAUTION. These words are used with the safety alert symbol.
DANGER identifies the most serious hazards which will result in severe personal injury or death. WARNING
signifies hazards which could result in personal injury or death. CAUTION is used to identify unsafe practices
which may result in minor personal injury or product and property damage. NOTE is used to highlight suggestions
which will result in enhanced installation, reliability, or operation.
The manufacturer shall not assume any liability for the damage caused by not observing the description of this
manual.
WARNING
General
•
Carefully read Owner’s Manual before starting the air conditioner. There are many important things to keep in mind for daily
operation.
•
Ask for installation to be performed by the dealer or a professional. Only a quali
fi
ed installer is able to install an air
conditioner. If a non-quali
fi
ed person installs an air conditioner, it may result in problems such as
fi
re, electric shock, injury,
water leakage, noise and vibration.
•
Do not use any refrigerant different from the one speci
fi
ed 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.
•
Do not install outdoor units where the operation sound may cause a disturbance. (Especially at the boundary line with a
neighbor, install the air conditioner while considering the noise.)
Installation
•
Only a quali
fi
ed installer or quali
fi
ed service person is allowed to carry out the electrical work of the air conditioner. Under
no circumstances must this work be done by an unquali
fi
ed individual since failure to carry out the work properly may result
in electric shocks and/or electrical leaks.
•
After the installation work has been completed, have the installer explain about the circuit breaker positions. In the event
that trouble has occurred in the air conditioner, set the circuit breaker to the OFF position, and contact a service person.
•
If the unit is installed in a small room, take appropriate measures to prevent the refrigerant from exceeding the limit
concentration even if it leaks. Consult the dealer from whom you purchased the air conditioner when you implement the
measures. Accumulation of highly concentrated refrigerant may cause an oxygen de
fi
ciency accident.
•
Do not install the air conditioner in a location that may be subject to a risk of exposure to a combustible gas. If a
combustible gas leaks and becomes concentrated around the unit, a
fi
re may occur.
•
If separately sold products are used, use TOSHIBA/Carrier speci
fi
ed products only. Using unspeci
fi
ed products may cause
fi
re, electric shock, water leak or other failure.
•
Connect ground wire. (grounding work) Incomplete grounding may cause an electric shock.
