CAUTION
Indicates a potentially hazardous situation that may result in
minor or moderate injury or damage to property.
Read carefully all safety information written in this manual before you install or use the
air conditioner.
Install the product by following local codes and regulations in force at the place of instal-
lation, and the instructions provided by the manufacturer.
This product is part of a set constituting an air conditioner. The product must not be
installed alone or be installed with non-authorized device 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 3 mm for this product.
To protect the persons, earth (ground) the product correctly, and use the power cable
combined with an Earth Leakage Circuit Breaker (ELCB).
The product is not explosion proof, and therefore should not be installed in explosive
atmosphere.
To avoid getting an electric shock, never touch the electrical components soon after the
power supply has been turned off. After turning off the power, always wait 5 minutes or
more before you touch the electrical components.
Do not touch the fins of the heat exchanger. Touching the heat exchanger fins could
result in damage to the fins or personal injury such as skin rupture.
This product contains no user-serviceable parts. Always consult experienced service
technicians for repairing.
When moving or relocating the air conditioner, consult experienced service technicians
for disconnection and reinstallation of the product.
Do not place any other electrical products or household belongings under the product.
Condensation dripping from the product might get them wet, and may cause damage or
malfunction of the property.
2. ABOUT THIS PRODUCT
2.1. Precautions for using the R410A refrigerant
WARNING
• Do not introduce any substance other than the prescribed refrigerant into the
refrigeration cycle.
If air enters the refrigeration cycle, the pressure in the refrigeration cycle will become
abnormally high and cause the piping to rupture.
• If there is a refrigerant leakage, make sure that it does not exceed the concentration
limit.
If a refrigerant leakage exceeds the concentration limit, it can lead to accidents such
as oxygen starvation.
• Do not touch refrigerant that has leaked from the refrigerant pipe connections or
other area. Touching the refrigerant directly can cause frostbite.
• If a refrigerant leakage occurs during operation, immediately vacate the premises
and thoroughly ventilate the area.
If the refrigerant comes in contact with a flame, it produces a toxic gas.
2.2. Special tool for R410A refrigerant
WARNING
• To install a unit that uses the R410A refrigerant, use dedicated tools and piping
materials that have been manufactured specifically for R410A use.
Because the pressure of the R410A refrigerant is approximately 1.6 times higher than
the R22, failure to use dedicated piping material or improper installation can cause
rupture or injury.
Furthermore, it can cause serious accidents such as water leakage, electric shock, or
fire.
Tool name Contents of change
Gauge manifold
• Pressure is huge and cannot be measured with a conventional
gauge. To prevent erroneous mixing of other refrigerants, the
diameter of each port has been changed.
It is recommended to use a gauge manifold with a high
pressure display range –0.1 to 5.3 MPa and a low pressure
display range –0.1 to 3.8 MPa.
Charging hose
• To increase pressure resistance, the hose material and base
size were changed.
Vacuum pump
• A conventional vacuum pump can be used by installing a
vacuum pump adapter.
Gas leakage
detector
• Special gas leakage detector for HFC refrigerant R410A.
1. SAFETY PRECAUTIONS
• 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.
WARNING
Indicates a potentially or imminently hazardous situation which,
if not avoided, could result in death or serious injury.
Installation of this product must be done by experienced service technicians or profes-
sional installers only in accordance with this manual. Installation by nonprofessional or
improper installation of the product may cause serious accidents such as injury, water
leakage, electric shock, or fire. If the product is installed in disregard of the instructions
in this 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 when you are working, ventilate the area. If the leaking refrigerant
is exposed to a direct flame it may produce a toxic gas.
Do not use this equipment with air or any other unspecified refrigerant in the refriger
-
ant lines. Excess pressure can cause a rupture.
Installation must be performed in accordance with regulations, codes, or standards for
electrical wiring and equipment in each country, region, or the installation place.
This appliance is not intended for use by persons (including children) with reduced
physical, sensory or mental capabilities, or lack of experience and knowledge, unless
they have been given supervision or instruction concerning use of the appliance by a
person responsible for their safety. Children should be supervised to ensure that they
do not play with the appliance.
To avoid danger of suffocation, keep the plastic bag or thin film used as the packaging
material away from young children.
