Safety Cautions
Warning !
Do not touch the fins on the heat exchanger
with bare hands:they are sharp and
dangerous.
When installing the unit in a small room,
safeguard against hypoxia that results from
leaked refrigerant reaching the threshold
level.
In the event of a refrigerant gas leak,
Consult the dealer for necessary measures to take.
provide adequate ventilation to the room.
If leaked refrigerant gas is exposed to a heat
source, noxious gases may form.
With All-Fresh type air cinditioners, outdoor
air may be directly blown into the room
upon thermo off. Take this into consideration
when installing the unit.
Direct expesure to outdoor air may present a
health hazard, and it may also cause food items
to deteriorate.
Do not try to defeat the safety features of
the devices, and do not change the settings.
Defeating the safety features on the unit such as
the pressure switch and temperature switch or
using parts other than the dealer or specialist
may result in fire or explosion.
When relocating the air conditioner,
consult the dealer or a specialist.
Improper installation may result in water leak,
electric shock, or fire.
After completing the service work, check
for a refrigerant gas leak.
If leaked gas refrigerant is exposed to a heat
source such as fan heater,stove,and electric grill,
noxious gases may form.
Only use specified parts.
Have the unit professionally installed.
Improper installation may cause water leak,
electric shock,smoke, or fire.
Precautions for handling Units for Use with R410A
Caution!
Do not use the existing refrigerant piping
The old refrigerant and refrigerator oil in the
existing piping contain a large amount of
chlorine, which will cause the refrigerator oil in
the new unit to deteriorate.
R410A is a high-pressure refrigerant,and the use
of the existing piping may result in bursting.
Keep the inner and outer surfaces of the
pipes clean and free of contaminants such
as sulfur, oxides, dust/dirt shaving particles,
oils,and moisture.
Contaminants inside the refrigerant piping will
cause the refrigerant oil to deteriorate.
Use a vacuum pump with a reverse-flowcheck valve.
If other types of valves are used, the vacuum
pump oil will flow back into the refrigerant cycle
and cause the refrigerator oil to deteriorate.
Do not use the following tools that have
been used with the conventional
refrigerants. prepare tools that are for
exclusive use with R410A.
(Gauge manifold, charging hose, gas leak
detector,reverse-flow check valve,
refrigerant charge base,vacuum gauge,
and refrigerant recovery equipment.)
If refrigerant and/or refrigerant oil left on these
tools are mixed in with R410, or if water is
mixed with R410A, it will cause the refrigerant
to deteriorate.
Since R410A does not contain chlorine, gas-leak
detectors for conventional refrigerators will not
work.

Safety Cautions
Caution!
Store the piping to be used during
installation indoors, and keep both ends of
the piping sealed until immediately before
brazing.(keep elbows and other joints
wrapped in plastic.)
If dust, dirt, or water enters the refrigerant cycle,
it may cause the oil in the unit to deteriorate or
may cause the compressor to malfunction.
Use a small amount of ester oil,ether oil, or
alkylbenzene to coat flares and flange
connections.
A large amount of mineral oil will cause the
refrigerating machine oil to deteriorate.
Use lipuid refrigerant to charge the system.
Charge the unit with gas refrigerant will cause
the refrigerant in the cylinder to change its
composition and will lead to a drop in
performance
Before Installing the Unit
Warning!
Do not use a charging cylinder.
The use of charging cylinder will change the
composition of the refrigerant and lead to power
loss.
Exercise special care when handling the
tools.
An introduction of foreign objects such as dust,
dirt, or water into the refrigerant cycle will cause
the refrigerating machine oil to deteriorate.
Only use R410A refrigerant.
The use of refrigerants containing chlorine(i.e.
R22) will cause the refrigerant to deteriorate.
Do not install the unit in a place where there
is a possibility of flammable gas leak.
Leaked gas accumulated around the unit may
start a fire.
Do not use the unit to preserve food,
animals, plants,artifacts, or for other special
purposes.
