Set-up Procedures

DANGER:  Do not fill while plugged in to wall outlet. Risk of electric shock!!!!

CAUTION: Do not use pump prior to filling and do not fully invert apparatus. 

  1. Place apparatus on stable structure.
  2. Fill system with potable water.
  3. Insert propeller assembly.
  4. Wire in accordance with Figure 1.
  5. Connect to 120 VAC source.

Assembling Propeller and Motor

First, place the motor assembly through the wooden 1” hole. Then simply screw the 4” brass propeller into the shaft. After that release the motor mount onto the wooden support.

Connecting Motor, Power Supply, and Ammeter

CAUTION:  Before connecting the motor assembly to the power supply make sure that the power supply is off.

CAUTION:  Make sure that the voltage dial is on zero (0) reading so that when power supply is turned on the propeller won’t start automatically.

Simulation Procedures

 

         NOTE: For all procedures, tank and piping system must be filled with water from a near-by supply.  A 120 VAC outlet is required for operation.

 

Figure 2 Piping and Valve assignments

Accelerating Ship

1.      Ensure system is wired in accordance with Figure 1.

2.      The main pump will remain off.

3.      The propeller will initially be stopped.

4.      All valves will remain closed.

5.      Receive data.

6.      Apply full propeller power.

7.      Slow propeller to stop when test is complete.

Cruising Ship

         NOTE: Please reference Figure 2 for valve assignment.

1.      Ensure system is wired in accordance with Figure 1.

2.      The pump will initially be stopped.

3.      The propeller will initially be stopped.

4.      Valves 1 and 2 are one-sixteenth turn open.

5.      Valve 3 is fully open.

6.      Valve 4 is one-eighth open.

7.      Valve 5 is fully open.

8.      Slowly increase propeller power until propeller reaches 55% full power.

WARNING: TURN OFF PUMP IF TANK FLOW BECOMES UNSTABE OR UNCONTROLLED

9.      While monitoring tank flow, turn on main pump.

10.   Open valves 1 and 2 one-sixteenth turn.

11.   Slowly open valve 4 less than one-sixteenth.

12.   Open valves 1 and 2 one-sixteenth turn.

13.   Close valve 3 one-sixteenth turn.

14.   Alternate between simantaous opening of valves 1 and 2 with closing of     valve 3 until desired flow is achieved.

15.    Receive data.

16.    Shut off main pump when test is complete.

17.    Slow propeller to stop.

Coasting Ship

         NOTE: Please reference Figure 2 for valve assignment.

1.      Ensure system is wired in accordance with Figure 1.

2.      The pump will initially be stopped.

3.      The propeller will initially be stopped.

4.      Valves 1 and 2 are one-sixteenth turn open.

5.      Valve 3 is fully open.

6.      Valve 4 is one-eighth open.

7.      Valve 5 is fully open.

          WARNING: TURN OFF PUMP IF TANK FLOW BECOMES UNSTABE

OR UNCONTROLLED

8.      While monitoring tank flow, turn on main pump.

9.       Open valves 1 and 2 one-sixteenth turn.

10.   Slowly open valve 4 less than one-sixteenth.

11.   Open valves 1 and 2 one-sixteenth turn.

12.   Close valve 3 one-sixteenth turn. Alternate between simantaous opening of valves 1 and 2 with closing of valve 3 until desired flow is achieved.

13.    Receive data.

14.    Shut off main pump when test is complete.

Crash Astern Maneuver

        NOTE: Please reference Figure 2 for valve assignment.

 

        WARNING:  TURN OFF PUMP IF TANK FLOW BECOMES UNSTABE OR

             UNCONTROLLED

1.      Complete Cruising Ship Checklist steps 1 though 15 to establish smooth flow.

2.       Receive data.

3.       Fully reverse propeller power.

4.       Shut off main pump when test is complete.

5.        Slow propeller to stop.

Disassembly Procedures

CAUTION:  Do not remove water while pump is in operation. 

CAUTION:   Do not fully invert apparatus. 

CAUTION:    Incline only to drain far pipes.

  1. Disconnect system from wall outlets.
  2. Disconnect all temporary wire connections.
  3. Remove and store propeller assembly.
  4. Utilizing supplied siphon drain water into bucket or drain.
  5. Tip apparatus to drain all water from piping system into tank.

*  Remove any remaining water with a sponge or paper towel
