In this blog post, we provide step-by-step assembly instructions that will help you get started with your LSP-500 configured in the flow-through mode. In addition, a link to a video on this topic is included at the end. In our next post, we will describe the disassembly steps for this processor.

  
**Let's begin with the assembly.**

![LSP-500 installation: place mylar acoustic washer over the connecting stud and turn horn clockwise](https://blog.sonomechanics.com/hs-fs/hubfs/General_Images/LSP-500_installation_place_mylar_washer_over_stud_turn_horn_clockwise1.0.jpg?width=191&name=LSP-500_installation_place_mylar_washer_over_stud_turn_horn_clockwise1.0.jpg "LSP-500 installation: place mylar acoustic washer over the connecting stud and turn horn clockwise")**1.** Inspect the Mylar acoustic washer for damage (make sure it's clean and free of scratches or particles) and place it over the connecting stud of the [**horn**](http://sonomechanics.com/technology/ultrasonic_horn_designs_and_properties/). If in doubt, replace it with a new one;

**2.** Thread the horn all the way into the [**transducer**](http://sonomechanics.com/technology/ultrasonic_transducers/)’s front mass by hand;

**3.** Use the provided spanner wrenches to tighten the assembly (see picture below):         
          a) Insert the pin of the first spanner wrench into a hole in the transducer’s front mass and set it up to provide **counterclockwise** torque.  
          b) Insert the pin of the second spanner wrench into a hole in the horn’s input end and set it up to provide **clockwise** torque.  
          c) Tighten by firmly pressing down with your palms on the wrenches, using the weight of your body. Please note, that *power overload* error during system operation may indicate an insufficiently tightened transducer-horn assembly;

**5.** Thread the support arm into the transducer and adjust the counter-nut by turning it clockwise by hand. Tighten using an adjustable wrench; 

![LSP-500 attach the support arm to the transducer](https://blog.sonomechanics.com/hs-fs/hubfs/General_Images/support_arm_thread-4.jpg?width=236&name=support_arm_thread-4.jpg "LSP-500 attach the support arm to the transducer")

**6.** Secure the ultrasonic stack in the support stand;

**7.** Briefly activate the ultrasonic output to check the power reading; 

| **TEST INSTRUCTIONS:** - Turn on the generator; - Press the AMPL button and use the up and down arrows to set the amplitude to 50%;               ![LSP_500 screen at 50 percent amplitude](https://blog.sonomechanics.com/hs-fs/hubfs/General_Images/50.jpg?width=275&name=50.jpg "LSP_500 screen at 50 percent amplitude") - Press ENTER; - Press the Stop/Start button to activate the ultrasound; - Press the ENTER button four times to get to the power reading screen; - Power reading should be under 15 W;               ![LSP_500 screen power reading watts](https://blog.sonomechanics.com/hs-fs/hubfs/General_Images/LSP_-_Manual_14-4_-_A.jpg?width=275&name=LSP_-_Manual_14-4_-_A.jpg "LSP_500 screen power reading watts") - Press the Stop/Start button to deactivate the ultrasound; - Repeat the same test at 100% amplitude;                ![LSP-500 screen amplitude reading at 100 percent](https://blog.sonomechanics.com/hs-fs/hubfs/General_Images/100.jpg?width=275&name=100.jpg "LSP-500 screen amplitude reading at 100 percent") - Power reading should be under 30 W;                ![LSP-500 system power screen reading watts](https://blog.sonomechanics.com/hs-fs/hubfs/General_Images/LSP_-_Manual_14-4_-_B.jpg?width=274&name=LSP_-_Manual_14-4_-_B.jpg "LSP-500 system power screen reading watts") - If the power reading is higher, disassemble and re-assemble the horn with transducer, tightening the connection; - All good? Turn off the generator and let's proceed to the next step.                |

To continue, we are going to place the reactor chamber on the support stand: 

**![LSP-500 assembly: insert the support arm in the reactor chamber](https://blog.sonomechanics.com/hs-fs/hubfs/General_Images/LSP-500_insert_the_support_arm-1.jpg?width=172&name=LSP-500_insert_the_support_arm-1.jpg "LSP-500 assembly: insert the support arm in the reactor chamber")8.** Thread the support arm into the reactor chamber and adjust the counter-nut by turning it clockwise by hand. Tighten using an adjustable wrench;

**9.** Secure the reactor chamber on the support stand;

**10.** Lower the ultrasonic stack, bringing the tip of the horn concentrically into the reactor chamber;

**11.** Make sure that the support arms of the transducer and reactor chamber are well-aligned and that the assembly is straight;

**12.** Place the 1.5” clamp over the horn and the reactor chamber (picture below) in such way that it is not blocking the outlet of the main working liquid lines; 

**13.** Tighten the 1.5" clamp and adjust the position of support stand clamp holders if necessary to relieve stress in the assembly;

**![LSP-500 assembling the flow-cell to horn flange connection ](https://blog.sonomechanics.com/hs-fs/hubfs/General_Images/flange_connection-1.jpg?width=361&name=flange_connection-1.jpg "LSP-500 assembling the flow-cell to horn flange connection ")14.** Briefly activate the ultrasonic output to check the power reading;

| **TEST INSTRUCTIONS:** - Repeat the test described above, at 50 % and 100 % amplitude settings;      ![LSP-500 second test: Amplitude screen reading at 50 percent](https://blog.sonomechanics.com/hs-fs/hubfs/General_Images/50.jpg?width=274&name=50.jpg "LSP-500 second test: Amplitude screen reading at 50 percent") ![LSP-500 second test: Amplitude screen reading at 100 percent](https://blog.sonomechanics.com/hs-fs/hubfs/General_Images/100.jpg?width=274&name=100.jpg "LSP-500 second test: Amplitude screen reading at 100 percent") - The power reading values should be under 20 W and 40 W, respectively.      ![LSP-500 power reading screen at 50 percent amplitude](https://blog.sonomechanics.com/hs-fs/hubfs/General_Images/LSP_-_Manual_14-4_-_C.jpg?width=274&name=LSP_-_Manual_14-4_-_C.jpg "LSP-500 power reading screen at 50 percent amplitude") ![LSP-500 power reading screen at 100 percent amplitude](https://blog.sonomechanics.com/hs-fs/hubfs/General_Images/LSP_-_Manual_14-4_-_D.jpg?width=274&name=LSP_-_Manual_14-4_-_D.jpg "LSP-500 power reading screen at 100 percent amplitude") |

**15.** Deactivate the ultrasonic output and turn off the generator;

**16.** Assemble the reactor chamber’s inlet and outlet hose connections using the ½" clamps;

**17.** If desired, connect a chiller or another cold water source to the reactor chamber’s cooling jacket for temperature control;

**18.** The working liquid will be pumped though the **[bottom fitting](http://sonomechanics.com/files/ultrasonic_systems/m_LSP-500%20all%20parts%20photo.jpg)** (the inlet) into the reactor chamber and collected through the [**upper right fitting**](http://sonomechanics.com/files/ultrasonic_systems/m_LSP-500%20all%20parts%20photo.jpg) (the outlet);

**19.** The LSP-500 system is now assembled and ready for continuous operation.
