 Check that cabling will not be subject 
to wear, corrosion, excessive pressure, 
vibration, sharp edges or any other 
adverse environmental effects.
  The check shall also take into account 
the effects of aging or continual vibration 
from sources such as compressors or 
fans.
  This equipment is strongly 
recommended to be installed with 
Earth Leakage Circuit Breaker (ELCB) 
or Residual Current Device (RCD). 
Otherwise, it may cause electrical 
shock and fire in case of equipment 
breakdown or insulation breakdown.
When Transporting
• It may need two or more people to carry
out the installation work.
• Be careful when picking up and moving
the indoor and outdoor units. Get a 
partner to help, and bend your knees 
when lifting to reduce strain on your 
back. Sharp edges or thin aluminum 
fins on the air conditioner can cut your 
fingers.
When storing…
 WARNING
• The appliance shall be stored
in a well-ventilated area where 
the room size corresponds to 
the room area as specified for 
operation.
• The appliance shall be stored
in a room without continuously 
operating open flames (for 
example: an operating gas 
appliance) and ignition sources 
(for example: an operating 
electric heater).
• The appliance shall be stored so as
to prevent mechanical damage from 
occurring.
When Installing…
• Select an installation location which is
rigid and strong enough to support or 
hold the unit, and select a location for 
easy maintenance.
• In cases that require mechanical
ventilation, ventilation openings shall be 
kept clear of obstruction.
…In a Room
Properly insulate any tubing run inside 
a room to prevent “sweating” that can 
cause dripping and water damage to 
walls and floors.
 CAUTION
Keep the fire alarm and 
the air outlet at least  
1.5 m away from the 
unit.
…In Moist or Uneven Locations
Use a raised concrete pad or concrete 
blocks to provide a solid, level foundation 
for the outdoor unit. This prevents water 
damage and abnormal vibration.
…In an Area with High Winds
Securely anchor the outdoor unit down 
with bolts and a metal frame. Provide a 
suitable air baffle.
…In a Snowy Area (for Heat Pump-
type Systems)
Install the outdoor unit on a raised 
platform that is higher than drifting snow. 
Provide snow vents.
(Type K2) 
...At least 1.8m 
Indoor unit of this air conditioner shall be 
installed in a height of at least 1.8 m.
…In laundry rooms
Do not install in laundry rooms. Indoor 
unit is not drip proof.
When Connecting Refrigerant 
Tubing
Pay particular attention to refrigerant 
leakages.
(Type Y2)
(Type U2, Type T2, Type F1, Type N1)
...At least 2.5m
Indoor unit of this air conditioner shall be

 WARNING
• When performing piping work, do 
not mix air except for specified 
refrigerant (R410A) in refrigeration  
cycle. It causes capacity down, and  
risk of explosion and injury due to  
high tension inside the refrigerant 
cycle.
• If the refrigerant comes in contact
with a flame, it produces a toxic 
gas.
• Do not add or replace refrigerant
other than specified type. It may 
cause product damage, burst and 
injury, etc.
• Ventilate the room immediately, in the
event that is refrigerant gas leaks during 
the installation. Be careful not to allow 
contact of the refrigerant gas with a 
flame as this will cause the generation 
of toxic gas.
• Keep all tubing runs as short as
possible.
• Use the flare method for connecting
tubing.
• Apply refrigerant lubricant to the
matching surfaces of the flare and union 
tubes before connecting them, then 
tighten the nut with a torque wrench for 
a leak-free connection.
• Check carefully for leaks before starting
the test run.
• Do not leak refrigerant while piping work
for an installation or re-installation, and 
while repairing refrigeration parts.  
Handle liquid refrigerant carefully as it 
may cause frostbite.
• Under no circumstances shall potential
sources of ignition be used in the 
searching or detection of refrigerant 
leaks.
• A halide torch (or any other detector
using a naked flame) shall not be used.
• Electronic leak detectors may be used
to detect refrigerant leaks but, the 
sensitivity may not be adequate, or 
may need re-calibration. (Detection 
equipment shall be calibrated in a 
refrigerant-free area.)
• Ensure that the detector is not a
potential source of ignition and is 
suitable for the refrigerant used.
• Leak detection fluids are suitable for
use with most refrigerants but the use of 
detergents containing chlorine shall be 
avoided as the chlorine may react with 
the refrigerant and corrode the copper 
pipe-work.
• If a leak is suspected, all naked flames
shall be removed/extinguished.
• If a leakage of refrigerant is found which
requires brazing, all of the refrigerant 
shall be recovered from the system, or 
isolated (by means of shut off valves) 
in a part of the system remote from the 
leak. Oxygen free nitrogen (OFN) shall 
then be purged through the system both 
before and during the brazing process.
When Servicing
• Contact to the sales dealer or service
dealer for a repair.
• Be sure to turn off the power before
servicing.
• Turn the power OFF at the main
power box (mains), wait at least 10 
minutes until it is discharged, then 
open 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.

 WARNING
• This product must not be
modified or disassembled under 
any circumstances. Modified or 
disassembled unit may cause fire, 
electric shock or injury.
• Do not clean inside the indoor and
outdoor units by users. Engage 
authorized dealer or specialist for 
cleaning.
• In case of malfunction of this
appliance, do not repair by 
yourself. Contact to the sales 
dealer or service dealer for a 
repair and disposal.
 CAUTION
• Ventilate any enclosed areas
when installing or testing the 
refrigeration system. Leaked 
refrigerant gas, on contact 
with fire or heat, can produce 
dangerously toxic gas.
• Confirm after installation that
no refrigerant gas is leaking. If 
the gas comes in contact with a 
burning stove, gas water heater, 
electric room heater or other 
heat source, it can cause the 
generation of toxic gas.
Others
When disposal of the product, comply 
with national regulations.
 WARNING
• Do not sit or step on the 
unit. You may fall down 
accidentally.
 CAUTION
• Do not touch the air inlet or 
the sharp aluminum fins of  
the outdoor unit. You may get  
injured.
• Do not stick any object into 
the FAN CASE.  
You may be injured and the  
unit may be damaged.
