3. Selecting Installation Position / 選擇安裝位置 (continued / 續)
[Electrical work / 電氣作業]
- Ensure the power cable and control switch
connection cable have a spare length of
around 2 m to allow the main unit to be
lowered. (If the cables are short, maintenance
becomes impossible)
- 確保電源線和控制開關連接電纜的備用長度約為2
m，以便降低主機。(如果電纜太短，則無法進行維
護)
[Duct piping / 管道配置]
- Use incombustible materials.
- 使用不可燃材料。
- Ensure the piping is for exclusive use with this
product.
- 確保配管為本產品專用。
- Tilt the piping downwards towards the outside
with a slant of at least 1/100 to prevent entry of
rainwater into the exhaust ducts and backflow
of condensed water.
- 將管道朝戶外向下傾斜至少1/100，以防止雨水進
入排氣管和冷凝水回流。
- To the end of the exhaust duct, attach a vent
cap (system component) to prevent entry of
rainwater or birds, or attach a hood (system
component) to prevent entry of rainwater.
- 在排氣管末端安裝通風蓋(系統組件)以防止雨水或鳥
類進入，或安裝罩蓋(系統組件)以防止雨水進入。
- Do not use a commercial outdoor hood with
a large pressure loss. (Could reduce the air
volume or increase noise)
- 請勿使用壓力損失大的市售戶外罩蓋。(可能導致風
量減小或噪音增大)
- Take note of the following. (Could reduce the air
volume or increase noise)
- 請注意以下事項。(可能導致風量減小或噪音增大)
・ Bend angle (R) / 彎曲角度(R)
・ Multiple bends / 多次彎曲
R＝
100mm
90°
・ Bend just next to the discharge opening
/
靠近排放口彎曲
At least 150 mm
至少150 mm
・ Pipe narrowing /
[Others / 其他]
- To use this product for general ventilation of
the house requires ventilation measures (such
as an undercut) in the door of the room.
- 若要將本產品用於房屋的一般換氣，需要針對房門
採取換氣措施(例如底切)。
- Provide an air vent.

- Do not use an impact driver to tighten the
screws in the panel. Tighten by hand.
- 請勿使用衝擊起子緊固面板中的螺絲。請用手緊
固。

Bend angle: At least 90˚
Bend radius (R): At least
the diameter of the duct
(For a ø100 spiral duct, have
R
a radius of at least 100 mm)
Prohibited
彎曲角度：至少90˚°
禁止
彎曲半徑(R)：至少為管
道直徑
(對於ø100的螺旋管道，半
徑至少為100 mm)
The distance that air
flows through straight
pipes will become shorter
as the number of bends
increase.
彎曲次數增加使空氣流過
直管的距離變短。
Ensure the bend is at
least 150 mm away from
the discharge opening.
確保彎曲離開排放口至少
150 mm。
管道變窄
Do not conduct pipe
narrowing.
請勿將管道收窄。
Prohibited
禁止
100 mm
