4.4. Perform operations 2.2-2.4 in the reverse order. Fans VN-1 80 KV, VN-1 80 KK and VN-1 80 KP contain fan assembly VN-1 80 and fan casing KV 80, KK 80 and KP 80, respectively. These fans are installed in two stages - i.e. the casing installation is followed by the final assembly: The casing is installed at the structural works stage.
