RETRACTABLE THRUSTER BTQR18 DP - IT GB - REV001A
Installation positioning
Directly access inside the hull, where the thruster will be installed.
Record the heights (
X Y Z
) detected on the larger side of the support.
Repeat the operation to also detect the heights of the shorter sides and adapt the support to the shape of the hull. Once trimmed
the support, temporarily lock in position marked (
REF
) to enable verifications of the final dimensions.

Position the thruster in stand-by position (closed) inside the hull, making it rest on the metal plate integral to the tunnel. Detect
the heights (
X Y Z
) between the lower part of the flange and the hull. Realise references (
REF
) that, once the thruster is removed,
enable arranging the support in the same position.
