SAFETY PRECAUTIONS
11
Be sure to read this Manual thoroughly before installation.
•
The warnings and precautions indicated in this Manual contain important
•
information pertaining to your safety. Be sure to observe them.
Hand this Manual, together with the Operating Manual, to the customer. Request
•
the customer to keep them on hand for future use, such as for relocating or
repairing the unit.
After installation, explain correct operation to the customer, using the operating
•
manual.
WARNING
This mark indicates procedures which, if improperly
performed, might lead to the death or serious injury of the
user.
Never touch electrical components immediately after the power supply has been
•
turned off. Electrical shock may occur. After turning off the power, always wait
10 minutes or more before touching electrical components.
Request your dealer or a professional installer to install the indoor unit in
•
accordance with this Installation Manual. An improperly installed unit can cause
serious accidents such as water leakage, electric shock, or fire. If the indoor unit
is installed in disregard of the instructions in the Installation Manual, it will void
the manufacturer’s warranty.
Do not turn ON the power until all work has been completed. Turning ON the
•
power before the work is completed can cause serious accidents such as
electric shock or fire.
If refrigerant leaks while work is being carried out, ventilate the area. If the
•
refrigerant comes in contact with a flame, it produces a toxic gas.
Installation work must be performed in accordance with national wiring
•
standards by authorized personnel only.
Do not use this equipment with air or any other unspecified refrigerant in the
•
refrigerant lines.
Excess pressure can cause a rupture.
During installation, make sure that the refrigerant pipe is attached firmly before
•
you run the compressor.
Do not operate the compressor under the condition of refrigerant piping not
attached properly with 2-way or 3-way valve open. This may cause abnormal
pressure in the refrigeration cycle that leads to rupture and even injury.
When installing and relocating the air conditioner, do not mix gases other than
•
the specified refrigerant (R410A) to enter the refrigerant cycle.
If air or other gas enters the refrigerant cycle, the pressure inside the cycle will
rise to an abnormally high value and cause rupture, injury, etc.
Do not remove the connection pipe while the compressor is in operation with
•
2-way or 3-way valve open.
This may cause abnormal pressure in the refrigeration cycle that leads to
rupture and even injury.
For the air conditioner to operate satisfactorily, install it as outlined in this
•
installation manual.
Connect the indoor unit and outdoor unit with the air conditioner piping and
•
cords available standards parts.
This installation manual describes the correct connections using the installation
set available from our standard parts.
Also, do not use an extension cord.
•
Do not purge the air with refrigerants but use a vacuum pump to vacuum the
•
installation.
There is not extra refrigerant in the outdoor unit for air purging.
•
Use a vacuum pump for R410A exclusively.
•
Using the same vacuum pump for different refrigerants may damage the
•
vacuum pump or the unit.
Use a clean gauge manifold and charging hose for R410A exclusively.
•
CAUTION
This mark indicates procedures which, if improperly
performed, might possibly result in personal harm to the
user, or damage to property.
Read carefully all security information before use or install the air conditioner.
•
Do not attempt to install the air conditioner or a part of the air conditioner by
•
yourself.
This unit must be installed by qualified personnel with a capacity certificate for
•
handling refrigerant fluids. Refer to regulation and laws in use on installation
place.
The installation must be carried out in compliance with regulations in force in the
•
place of installation and the installation instructions of the manufacturer.
This unit is part of a set constituting an air conditioner. It must not be installed
•
alone or with non-authorized by the manufacturer.
Always use a separate power supply line protected by a circuit breaker operating
•
on all wires with a distance between contact of 3mm for this unit.
The unit must be correctly grounded and the supply line must be equipped with
•
a differential breaker in order to protect the persons.
The units are not explosion proof and therefore should not be installed in
•
explosive atmosphere.
Do not turn on the power until all installation work is complete.
•
Never touch electrical components immediately after the power supply has been
•
turned off. Electric shock may occur. After turning off the power, always wait 5
minutes before touching electrical components.
This unit contains no user-serviceable parts. Always consult authorized service
•
personnel to repairs.
When moving, consult authorized service personnel for disconnection and
•
installation of the unit.
Children should be monitored to ensure they do not play with the device.
•
This product is not intended to be used by people (including children) with
•
physical, sensory or mental disability, or persons lacking experience or
knowledge unless they have been given by the through a person responsible for
their safety, supervision or instruction concerning the use of the device.
