While mounting the fan avoid the casing compression!
Deformation of the casing may result in the motor jam and excessive
noise.
Misuse of the fan and any unauthorised modifications are not allowed.
Take steps to prevent ingress of smoke, carbon monoxide and other
combustion products into the room through open chimney flues or
other fire-protection devices. Sufficient air supply must be provided
for proper combustion and exhaust of gases through the chimney of
fuel burning equipment to prevent back drafting.
Transported air must not contain any dust or other solid impurities,
sticky substances or fibrous materials.
