INSTALLATION INSTRUCTION
3 Installation Instruction
>Secured upon the strengthened foundations for
installation.
Be sure to take reinforcement measures if required for
sufcient instalIation strength.
Improper installation may cause accident
because of the falling of the product.
> Specied number and size of the bolts should be used
for hanging the unit and they must be tightened.
May cause injury due to insufcient strength.
>Beware of C.G. and weight when moving.
Hang only as the unit is normally assembled,
or else it may drop and cause injury.
>Electrical installations should be doneaccording to the
wiring diagram and localelectrical wiring rules of xed
wiring.
Unqualied wiring may cause electric shock or
re.
>Weight of duct should not load on the unit.
May cause injury due to malfunctions or
dropping.
>Grounding should be connected.
May cause electric shocks.
2
> Precautions must be taken to avoid the back-ow of
gases into the room from the open ue of gas or other
fuel-burning appliances.
May cause back-ow gases.
>Avoid a location with high temperatures.
TroubIe may be caused and the motor life may
be shortened.
>Do not instal l the fan where the humidity is high (85%
or higher) such as near a swimming pool, public hot
spring bathing area or outdoors.
>Avoid a location with too much oil fume.
>Install a fan protection device like a motor overload
breaker in the wiring.
>There should be an all poles switch with min.3mm
contact gap in the xed wiring.
>Connect the duct avoiding the following cases.
1) Sharp bending angle;
2) Bended more than once;
3) Reduced diameter at the connection;
4) Bending near the discharge port and suction
port.
>During installation or maintenance, the power cord
should be lower than the outlet of terminal box.
May cause water ow along the power cord
into wiring box or scrape the power cord.
>The installation height of Cabinet Fan shall be more
than 2.3m above the oor.
Prevent accident
>The motor and frame should not touch any object.
May cause vibration and noise.
Caution:
1. When ventilating a room that use combustion equipment with a chimney, provide a suction port large enough.
The size of the suction port should be decided by the instruction of the combustion equipment. (Exhaust gas may
reverse into the room, which may cause carbon monoxide poisoning.)
2. For an exhaust duct to outdoor, attach a pipe hood to the end and keep at least a 1/100 slant downward. (To
prevent rain or frozen water entering.)
3. Heat insulation should be taken if there is dewfall outside of the adapter and frame when indoor heating in winter.

INSTALLATION INSTRUCTION
1. Before installation
Check the following:
1) is there any breakage or deformation?
2) check the power source of product before installation
3) to avoid insect intrusion, please purchase a separately sold insect lter unit from the market. (The lter unit
should be bought by customer and must be cleaned periodically to prevent clogging with dirt and dust.
Furthermore, the lter will make pressure losing and it may reduce the air volume.)
2. Installation method
To hang the fan, be sure to attach rmly with hanger bolts, washers and nuts. (Which should be M8~M10 and be
supplied by the customer); Install the main body horizontally.
Vibration cushion rubber set (supplied by the customer) can be used if in special condition for vibration requirement
and it must can support the weight of the product.
The structure of the ceiling and the suspending set for hanging the product must support more than 5 times weight
of the product.
Install the exterior duct with a slightly declining slope toward outer side. (1/100 ~ 1/50)
Be sure to provide an square inspection window of 45 cm or more.
Connect the circular duct to the adapter using noncombustible sailcloth.
Heat insulation should be taken if there is dewfall outside of the duct and frame.
