contact the dealer or an
Authorized Service Center.
• There is risk of fire, electric
shock, explosion, or injury.
Do not install the product on a
defective installation stand.
• It may cause injury, accident, or
damage to the product.
Do not let the product run for a
long time when the humidity is
very high and a door or a
window is left open.
• Moisture may condense and wet
or damage furniture.
For re-installation of the
installed product, always
contact the dealer or an
Authorized Service Center.
• There is risk of fire, electric shock,
explosion or injury.
Do not open the
maintenance cover of the
main body during operation.
• Otherwise, it may cause electrical
shock.
Use the outdoor air suction
hole with the net installed to
ensure that birds could not
come in.
• Remove estrange things like the
bird’s nest. Otherwise, it may
cause scarcity of indoor oxygen.
Install the air intake where
polluted air can not be
directly sucked in.
• It may cause various accidents,
including suffocation, due to the
suction of harmful gasses(CO, etc.)
Do not install this product in
a refrigerated warehouse,
heated swimming pool or
other location where the
temperature and humidity
are significantly different.
• There is risk of electrical shock,
malfunctioning.
Install this product in an
environment where the
temperature ranges from –10°C to
+45°C and the relative humidity is
less than 80%. It condensation is
expected to form, heat up the fresh
outside air using a duct heater etc.
Install this product in and
environments where the outside
air intake meets the following
conditions: temperature range
is between –15°C and +40°C and
the relative humidity is 80% or
less.
Use the designated electrical
wires for the terminal board
connections, and connect the
wires securely so that they will
not become disconnected.
(Failure to ensure proper
connections may cause fire.)
When passing metal ducts
through wooden buildings clad
with metal laths, wire laths or
metal, these ducts must be
installed in such a way that they
will not make electrical contact
with the metal laths, wire laths
or metal sheets. (Power leakage
can cause ignition)
Avoid fire equipment
• There is risk of fire.
When the product is soaked
(flooded or submerged), contact
an Authorized Service Center.
• There is risk of fire or eletric shock.

Safety Precautions
Be cautious that water could not enter the
product.
• If water enters the product, there is risk of re, electric
shock, or product damage.
Turn the breaker o when cleaning or
maintaining the product.
• There is risk of electric shock, if product is cleaned while the
breaker is on.
The outside ducts must be tilted at a gradient
(1/30 or more) down toward the outdoor area
from the ventilator unit, and properly insulated.

smoky and oily place like
kitchen or factory.
• Otherwise. oil may adhere to the
lter or heating exchanger and cause
trouble.
Install the product in an
insulated space from outdoor
air.
• If the product is installed outside of the
insulated layer, dewing occurs inside of
the main body in winter and it causes
electrical shock or falling of condensed
water.
Installation
Keep level even when
installing the product.
• To avoid vibration or water
leakage.
Use two or more people to
lift and transport the
product.
• Avoid personal injury.
Do not install the product where
it will be exposed to sea wind
(salt spray) directly.
• It may cause corrosion on the
product. Corrosion, particularly on
the condenser and evaporator ns,
could cause product malfunction or
inefficient operation.

not use harsh detergents, wax
or thinner, etc.
• Otherwise, color or surface of the
oroduct mav deteriorate.
Clean the lter and the heat
exchanger regularly and use
the gloves for cleaning.
• Accumulation of dust or debris
causes the deterioration of air volume.
Do not use the product for special
purposes, such as preserving
foods, works of art, etc. It is a
consumer ventilator, not a
precision refrigeration system.
• There is risk of damage or loss of
property.

right figure.
• For the ceiling fixing bolt, perform work less than
50mm(1.97in) under the ceiling fixing bracket.
Connection of Duct
1. After securely connect the duct with the duct connection flange, wrap it
with a commercial aluminium tape so that air cannot be leaked.
2. Adjust the duct from the ceiling so that no force is applied to the main
body of the ventilation system.
3. Always use two ducts at the outdoor with the heat insulating material for
prevention of dewing.

CAUTION:
• Check that there are no foreign
materials (paper, vinyl, etc) or cutoff
powders in the duct before connecting
the duct.
• Take care so that shock may not be
applied to the damper plate within the
main body when performing the duct
connection work.
• It is recommended to perform
adiabatic treatment even to the duct
pipe at the indoor side where ambient
temperature is expected higher than
room temperature when the main body
of the ventilation system for cooling in
summer.
• Take care so that work may not be
performed as in the left figure.
Otherwise, it may cause reduction of
air volume or abnormal noise.
CAUTION:
•
In -10℃ below ambient temperature, when ventilation is installed the equivalent space in
the outdoor and outdoor, It may cause condensation, you must install drainage
facilities(Drain Pan) and MD(Moterized Damper) at SA/RA duct.

• For wiring, use the designated power wire and connect firmly, then secure to prevent outside pressure
being exerted on the terminal block.
• Use an appropriate screwdriver for tightening the terinal screws. A screwdriver with a small head will
strip the head and make proper tighterning impossible.
• Over-tightening the terminal screws may break them.
When none are available, follow the instructions below.
• Do not connect wiring of different thicknesses to the power terminal block. (Slack in the power
wiring may cause abnormal heat.)
• When connecting wiring which is the same thickness, do as shown in the figure below.

Refer to the product manual for more detail.
When controlling multiple indoor units with event communication function with one remote
controller, you must change the master/slave setting from the indoor unit.
- Indoor units, the master/slave configuration of the product after completion of indoor unit power
‘OFF’ and then ‘ON’ the power after 1 minutes elapsed sign up.
- For ceiling type cassette and duct product group, change the switch setting of the indoor PCB.
- For wall-mount type and stand type product, change the master/slave setting with the wireless
remote controller. (Refer to wireless remote controller manual for detail)
❈When installing 2 remote controllers to one indoor unit with event communication function, set
the master/slave of the remote controller. (Refer to remote controller master/slave selection)
When controlling the group, some functions excluding basic operation setting, fan level
Min/Mid/Max, remote controller lock setting and time setting may be limited.
<When simultaneously connecting
