Lewmar Swing Thruster Product and Installation Manual ref 500146 iss.3 | 3
IMPORTANT: These notes must be read before attempting installation.
‣ This product requires detailed fitting and set-up to suit the particular installation. Failure
to correctly install or set-up the unit can damage the unit or result in premature failure.
‣ The thruster must be installed such that the hatch opens towards
the normal water flow direction. Failure to do so will result in
excess stresses being placed on the hatch, leg and actuator, which
could result in failure. See diagram below.
2.3- Common Installation Errors
⚠
water flow
‣ NEVER power the motor flange via the actuator without the motor bolted in
place. This will cause the motor flange to crack.
‣ The thruster uses two methods to determine the limits of the tunnel
movement.
- When deploying the tunnel, the actuator must be allowed to reach its
own internal “minimum extension” microswitch.
- When retracting the tunnel, the electronics sense a current spike when
the lid contacts with the hull and automatically cut power.
‣ When deployed, ensure that the leg of the thruster does not impact on the edge of the hull. If it does, the hull
should be filed away to give clearance.
‣ When laminating the box into the hull, the laminate layers should
extend up and over the coach bolt heads on each side of the box.
‣ NEVER cut the original cables, or attempt to connect cables with anything other than the original plugs and sockets.
