Estimated time: 1h

Tools needed:

Screwdriver, Wire strippers, Multimeter

Supplies needed:

Mounting screws, Terminal connectors, Gasket

  1. Unpack and Inspect the Equipment

    Carefully unpack the MSL2-024AR unit and inspect it for any damage that may have occurred during transit. If damaged, do not proceed with installation and file a claim with the carrier.

  2. Mount the Base

    Remove the colored lenses by twisting the bottom lens counter-clockwise until it unlocks. Lift the bottom lens off. Remove the two Phillips head #6 screws to disassemble the sleeve from the base. Mount the base onto a 3/4" NPT pipe or a flat surface using the provided screws, ensuring it is securely fastened.

  3. Make Electrical Connections

    Feed the control wires through the NPT opening in the base. Connect the wires to the female terminal block plug according to the labeled terminals (1-5). Ensure power is off during this process to avoid electrical shock hazards.

  4. Reassemble the Unit

    Reattach the sleeve(s) to the base by sliding the printed circuit board into the channels and securing with the screws removed earlier. Ensure that O-rings are in place to maintain a watertight seal.

  5. Install the Colored Lenses

    Reassemble the colored lenses onto the base unit, ensuring an O-ring is placed between each lens for a watertight seal. Twist each lens clockwise until it locks into place.
