Do not clean the air conditioner by splashing water.
Washing the unit with water can cause an electrical shock.
Be sure to provide the grounding when repairing the equipment in a humid or wet place,
to avoid electrical shocks.
Be sure to turn off the power switch and unplug the power cable when cleaning the
equipment.
The internal fan rotates at a high speed, and cause injury.
Do not tilt the unit when removing it.
The water inside the unit can spill and wet the furniture and floor.
Be sure to check that the refrigerating cycle section has cooled down sufficiently before
conducting repair work.
Working on the unit when the refrigerating cycle section is hot can cause burns.
Use the welder in a well-ventilated place.
Using the welder in an enclosed room can cause oxygen deficiency.
Warning
Besuretousepartslistedintheserviceparts list of the applicable model and appropriate
tools to conduct repair work. Never attempt to modify the equipment.
The use of inappropriate parts or tools can cause an electrical shock, excessive heat
generation or fire.
When relocating the equipment, make sure that the new installation site has sufficient
strength to withstand the weight of the equipment.
If the installation site does not have sufficient strength and if the installation work is not
conducted securely, the equipment can fall and cause injury.
Be sure to install the product correctly by using the provided standard installation frame.
Incorrect use of the installation frame and improper installation can cause the equipment
to fall, resulting in injury.
For integral units only
Be sure to install the product securely in the installation frame mounted on a window
frame.

Do not mix air or gas other than the specified refrigerant (R-407C) in the refrigerant
system.
If air enters the refrigerating system, an excessively high pressure results, causing
equipment damage and injury.
If the refrigerant gas leaks, be sure to locate the leak and repair it before charging the
refrigerant. After charging refrigerant, make sure that there is no refrigerant leak.
If the leak cannot be located and the repair work must be stopped, be sure to perform
pump-down and close the service valve, to prevent the refrigerant gas from leaking into
the room. The refrigerant gas itself is harmless, but it can generate toxic gases when it
contacts flames, such as fan and other heaters, stoves and ranges.
When replacing the coin battery in the remote controller, be sure to disposed of the old
battery to prevent children from swallowing it.
If a child swallows the coin battery, see a doctor immediately.
Warning
Caution
Installation of a leakage breaker is necessary in some cases depending on the
conditions of the installation site, to prevent electrical shocks.
Do not install the equipment in a place where there is a possibility of combustible gas
leaks.
If a combustible gas leaks and remains around the unit, it can cause a fire.
Be sure to install the packing and seal on the installation frame properly.
If the packing and seal are not installed properly, water can enter the room and wet the
furniture and floor.
For integral units only
Warning
Check to make sure that the power cable plug is not dirty or loose, then insert the plug
into a power outlet all the way.
If the plug has dust or loose connection, it can cause an electrical shock or fire.
If the power cable and lead wires have scratches or deteriorated, be sure to replace
them.
Damaged cable and wires can cause an electrical shock, excessive heat generation or
fire.
Do not use a joined power cable or extension cable, or share the same power outlet with
other electrical appliances, since it can cause an electrical shock, excessive heat
generation or fire.
Caution
Check to see if the parts and wires are mounted and connected properly, and if the
connections at the soldered or crimped terminals are secure.
Improper installation and connections can cause excessive heat generation, fire or an
electrical shock.

1.2 Outline of New Series Products
In addition to the use of a new refrigerant (R-407C), the new series products incorporate a function-unit-less structure
for significantly improved flexibility and ease of installation.
System outline

No function unit
All models combine master units and slave units or master units, slave units and Plus units.
All models use a new refrigerant with low ozone destruction potential and global warming potential to
minimize environmental loads (see Feature (1)).
With a value of 1 given to the ozone destruction potential and global warming potential of the R11
refrigerant, smaller values mean less environmental impact.
Feature (1)
Use of new refrigerant (R-407C) that does not deplete the ozone layer
Reduction of refrigerant charge volume (approx. 75% as compared to R22-refrigerant unit with 20 HP
and 5-m pipe)
--- Mainly by elimination of function units, simplification of refrigerant circuits and reduction of internal
volume.
< Global warming potential >
Water vapor and carbon gas allow solar rays to pass through, but they hinder the penetration of heat rays
from the surface of the earth. Methane, chlorofluorocarbons and dinitrogen monoxide have similar
characteristics. When the amounts of these gases in the atmosphere increase, heat that normally escapes
through the atmosphere remains near the earth's surface, thus increasing the temperature of air. The
degree of the effect to the earth caused by the atmospheric temperature rise due to these gases is
numerically expressed by global warming potential (GWP).
Feature (2)
Dramatically improved flexibility and ease of field installation by function-unit-less structure
--- Simpler piping work at installation sites
--- Reduced unit installation area
