s The contents of this section are vital to ensure safety. Please pay special attention to the following sign.
WARNING .......... Incorrect methods of installation may cause death or serious injury.
CAUTION .......... Improper installation may result in serious consequence.
Make sure to connect earth line.
This sign in the figures indicates prohibition.
Be sure that the unit operates in proper condition after installation. Explain to customer the proper operation and maintenance of
the unit as described in the user' s guide. Ask a customer to keep this installation manual together with the instruction manual.
WARNING
s Please request your sales agent or qualified technician to install your unit. Water leakage, short circuit or fire may occur if you do the
installation work yourself.
s Please observe the installation stated in the installation manual during the process of installation. Improper installation may cause
water leakage, electric shock and fire.
s Make sure that the units are mounted at locations which are able to provide full support to the weight of the units. If not, the units may
collapse and impose danger.
s Observe the rules and regulations of the electrical installation and the methods described in the installation manual when dealing
with the electrical work. Use cables which are approved official in your country. Be sure to use the specified circuit. A short circuit and
fire may occur due to the use of low quality wire or improper work.
s Be sure to use the specified cables for connecting the indoor and outdoor units. Please ensure that the connections are tight after the
conductors of the wire are inserted into the terminals to prevent the external force is being applied to the connection section of the
terminal base. Improper insertion and loose contact may cause over-heating and fire.
s Please use the specified components for installation work. Otherwise, the unit may collapse or water leakage, electric shock, fire or
stronger vibration may occur.
s
Be sure to use the specified piping set for R410A. Otherwise, this may result in broken copper pipes or faults.
s
When installing or transferring an air conditioner to another location, make sure that air other than the specified refrigerant (R410A)
does not enter the refrigeration cycle. If other air should enter, the pressure level of the refrigeration cycle may increase abnormally
which could result in a rupture and injury.
s Be sure to ventilate fully if a refrigerant gas leak while at work. If the refrigerant gas comes into contact with fire, a poisonous gas may
occur.
s After completion of installation work, check to make sure that there is no refrigeration gas leakage. If the refrigerant gas leaks into the
room, coming into contact with fire in the fan-driven heater, space heater, etc., a poisonous gas may occur.
s Unauthorized modifications to the air conditioner may be dangerous. If a breakdown occurs please call a qualified air conditioner
technician or electrician. Improper repairs may result in water leakage, electric shock and fire, etc.
s Be sure to connect the earth line from the power supply wire to the outdoor unit and between
the outdoor and indoor unit. Do not connect the earth line to the gas tube, water pipe, lighting rod or the earth line of the
telephone unit. Improper earthing may cause electric shocks.
s When finishing the refrigerant collection (pumping down), stop the compressor and then remove the coolant pipe.
If you remove the refrigerant pipe while the compressor is operating and the service valve is released, air is sucked and a
pressure in the freezing cycle system will build up steeply, causing an explosion or injury.
s When installing the unit, be sure to install the refrigerant pipe before starting the compressor.
If the refrigerant pipe is not installed and the compressor is operated with the service valve released, air is sucked and the
pressure level of the refrigeration cycle may increase abnormally which could result in a rupture and injury.
A circuit breaker must be installed in the house distribution box for the direct
connected power supply cables to the outdoor unit. In case of other
installations
a main switch with a contact gap or more than 3mm has to be installed.
Without a circuit breaker, the danger of electric shock exists.
Do not install the unit near a location where there is flammable gas.
The outdoor unit may catch fire if flammable gas leaks around it.
Please ensure smooth flow of water when installing the drain hose. Improper
installing may wet your fu niture.
An IEC approved power cord should be used. Power cord type:
NYM.
