Installation instruction

Connection to duct

The return air damper in LQVF is connected to the

duct on the side (b = 1) or on the bottom (b = 2) using

the following accessories: fabric sleeve LQVZ-02,

transition piece LQVZ-03 and counterflange LQVZ-

04. Alternatively, an edged duct can be screwed

directly to the casing. Sealing strip LQAZ-10 is requi-

red in every case. Ensure that the ducts do not impose
