Temporarily set up the complete installation to ensure no confl icts during the fi nal operation of the thruster.
1. Use silicon in the 4 corners of the SRF fl ange and set it over the hatch. Attach the motor unit to the SRF fl ange with 4 corner screws to hold
securely in place. use silicon to attach the hatch to the propeller unit. (NB: Ensure correct orientation for the thruster to open the hatch facing the
direction of water fl ow. Remember attachment is for temporary checking of thruster operation only.)
2. Temporarily connect 12 or 24 DC cables (refer to the label on actuators for correct voltage) to the 6 mm cables on the terminals on the controller.
Set switch no. 4 on the DIP-switch marked “SETTINGS” to ON. Remove the wooden safety part located above the propeller.
3. Press “DOWN” to extend the retract mechanism and check the hatch opens fully without touching the hull. If the hatch is obstructed by the hull, lift
the aft end of the SRF fl ange maintaining the reference height in front - until the hatch clears the hull when opened.
4. Press “UP” to retract the propeller mechanism. Ensure when the hatch is closed extra pressure is on the contact surface between the hatch and
the hull only. If the hatch is not closing with pressure on the contact surfaces the entire SRF fl ange must be raised. (NB:
After all, pre-checks are compleated the SR system can be installed.
