Ex.3: Avoid reduced hose diameter,
E.g., reduced mid-section diameter prohibited.
Ex.4: Avoid bending close to outlet.

Air Hose Minimum Bend Radius:
Dia.100mm Hose: 100mm; Dia.150mm Hose: 150mm; Dia.200mm Hose: 300mm; Dia.250mm Hose: 375mm
c.
To prevent air leakage, joint section between flange and air hose shall be wrapped with aluminum foil.
d.
To prevent short circuit, indoor air inlet shall be installed as far away from air outlet as possible.
e.
Please choose air hoses with specs conforming to unit model.
f.
Install two external air hoses with regular
obliquity (not below 1/30) to prevent rain water
from back- flowing. At the same time, heat
insulant shall be available for all three air hoses
(two outdoor and one indoor) lest condensed
water ensues. (Insulant material: glass wool
25mm thick) (Refer to diagram on the right)
g.
In case of constant high temperature and
humidity in suspended ceiling, install ventilation
device in ceiling.

Soft hose and wind softening hose can
effectively reduce exhaust noises.
Fan strength and operating noise shall be
considered when choosing material. Distributors
of products shall be entrusted to choose
material.
i.
Default distance between air outlet EA and air inlet OA shall be two times longer that hose diameter.
j.
Do not use bent service lid or dome shield as external shield; otherwise, rain water will directly enter. (Deepened
shield is recommended).
k.
Make sure that air hose is at least 1 meter away from shield.
Air Hose Joint Flange
