Vehicles and ships.
 
Locations where cosmetic or special sprays are
often used.
 
Locations with direct exposure of oil mist and
steam such as kitchen and machine plant.
 
Locations where any machines which generate
high frequency harmonics are used.
 
Locations with salty atmospheres such as
coastlines.
 
Locations with heavy snow (If installed, be sure
to provide base fl ame and snow hood mentioned
in the manual).
 
Locations where the unit is exposed to chimney
smoke.
 
Locations at high altitude (more than 1000m
high).
 

 
Locations where heat radiation from other heat
source can aff ect the unit.
 
Locations without good air circulation.
 
Locations with any obstacles which can prevent
inlet and outlet air of the unit.
 
Locations where short circuit of air can occur (in
case of multiple units installation).
 
Locations where strong air blows against the air
outlet of outdoor unit.
It can cause remarkable decrease in performance,
c o r r o s i o n a n d d a m a g e o f c o m p o n e n t s ,
malfunction and fi re.
Do not install the outdoor unit in the
locations listed below.
 
Locations where discharged hot air or operating

neighborhood.
 
Locations where outlet air of the outdoor unit
blows directly to plants.
 
Locations where vibration can be amplifi ed and
transmitted due to insufficient strength of
structure.
 
Locations where vibration and operation sound
generated by the outdoor unit can affect
seriously. (on the wall or at the place near bed
room)
 
Locations where an equipment aff ected by high
harmonics is placed. (TV set or radio receiver is
placed within 5m)
 
Locations where drainage cannot run off safely.
It can aff ect surrounding environment and cause a
claim.
Do not install the remote controller at
the direct sunlight.
It can cause malfunction or deformation of the
remote controller.
Do not use the unit for special purposes
such as storing foods, cooling precision
instruments and preservation of
animals, plants or art.
It can cause the damage of the items.
Take care when carrying the unit by
hand.
If the unit weights more than 20kg, it must be
carried by two or more persons. Do not carry by
the plastic straps, always use the carry handle
when carrying the unit by hand. Use gloves to
minimize the risk of cuts by the aluminum fi ns.
Dispose of any packing materials cor-
rectly.
Any remaining packing materials can cause
personal injury as it contains nails and wood. And
to avoid danger of suff ocation, be sure to keep the
plastic wrapper away from children and to dispose
after tear it up.
Pay attention not to damage the drain
pan by weld spatter when welding
work is done near the indoor unit.
If weld spatter entered into the indoor unit during
welding work, it can cause pin-hole in drain pan
and result in water leakage. To prevent such
damage, keep the indoor unit in its packing or
cover it.
Be sure to insulate the refrigerant pipes
so as not to condense the ambient air
moisture on them.
Insufficient insulation can cause condensation,
which can lead to moisture damage on the ceiling,
fl oor, furniture and any other valuables.
Be sure to perform air tightness test
by pressurizing with nitrogen gas after
completed refrigerant piping work.
If the density of refrigerant exceeds the limit in
the event of refrigerant leakage in the small room,
lack of oxygen can occur, which can cause serious
accidents.
Do not touch any buttons with wet hands.
It can cause electric shocks.
Do not shut off the power supply imme-
diately after stopping the operation.
Wait at least 5 minutes, otherwise there is a risk
of water leakage or breakdown.
Do not control the system with main
power switch.
It can cause fi re or water leakage. In addition, the
