1.Safety Precautions
Safety Precautions
Important!
This air conditioning system meets strict safety and
operating standards. As the installer or service person,
it is an important part of your job to install or service the
system so it operates safely and efficiently.
Follow each installation or repair step exactly as shown.
Observe all local, state, and national electrical codes.
Pay close attention to all warning and caution notices
given in this manual.
To prevent injury to the user or other people and
property damage, the following instructions must
be followed.
About the pictures:
Erroneous handing gives a high possi-
bility to induce serious results such as
death or heavy injury.
Erroneous handing may induce serious
injury depending on the situation.
Do not supply power to the unit until all wiring and tubing
are completed or reconnected and checked.
Highly dangerous electrical voltages are used in this
system. Carefully refer to the wiring diagram and these
instructions when wiring. Improper connections and inad-
equate grounding can cause accidental injury or death.
Ground the unit following local electrical codes.
Connect all wiring tightly. Loose wiring may cause over-
heating at connection points and a possible fire hazard.
All electric work must be performed by licensed technician, ac-
cording to local regulations and the instructions given in this
manual.
There is risk of fire, electric shock, explosion, or injury.
Ask your dealer or specialized subcontractor for installation or
repair work.
Make sure the ceiling/wall is strong enough to hold the
unit’s weight. The outdoor unit should be installed in a
location where air and noise emitted by the unit will not
disturb the neighbors.
Properly insulate any tubing run inside a room to prevent
"sweating" that can cause dripping and water damage to
walls and floors.
The outdoor unit must be installed on stable, level surface,
in a place where there is no accumulation of snow, leaves
or rubbish.
The unit should be installed according to the instructions
in order to minimize the risk of damage from earthquakes,
typhoons or strong winds.
When the refrigerant touches the fire etc., it was decomposed
and a poisonous gas is generated.
Use only the specified refrigerant to charge the refrigerant
circuit.
Do not mix it with any other refrigerant and do not allow air to
remain in the circuit.
Air enclosed in the circuit can cause high pressure resulting
in a rupture and other hazards.
After completing installation work, make sure that refriger-
ant gas has not leaked.
The limit density is made not to be exceeded even if the refrig-
erant leaks by any chance.
Turn the power off at the main power box (mains) before open-
ing the unit to check or repair electrical parts and wiring.
Keep your fingers and clothing away from any moving parts.
Clean up the site after you finish, remembering to check that
no metal scraps or bits of wiring have been left inside the unit
being serviced.
The unit must be properly earth connected.
Caution
Warning
Warning
Caution
Never install on the place where a combustible gas might
leak. The gas may ignite or explode when the gas leaks and
collects in surround of the unit.
When the unit is installed at telecommunication centers or
hospitals, take a proper provision against noise.
When installing at a watery place, provide an electric leak
breaker.
Do not wash the unit with water.
Be very careful about unit transportation. The unit should not
be carried by only one person if it is more than 20kg. It occasion-
ally causes the damage of theunit and health to be impaired.
Do not touch the heat exchanger fins with your hands.
Doing so may cut your hands.
Do not touch the compressor or refrigerant piping without
wearing glove on your hands. Touching directly such part can
cause a burn or frostbite as it becomes high or low temperature
according to the refrigerant state.
Do not operate the air conditioner without the air filter set
place. Dust may accumulate, and cause a failure.
At emergency (if you smell something burning), stop opera-
tion and turn the power source switch off.
