    Place the fiber holder into the thermal stripper to strip
    the fiber.

    The stripped fiber must be cleaned with a tissue dampened
    with 99% Isopropyl alcohol or with the Stickler Connector
    Cleaner.

    A properly cleaned fiber is necessary for a successful cleave
    and splice.

    Place the outdoor fiber holder into the cutting device close
    the cover slowly, firmly pressing the “pusher-pin” the cutting
    is performed by the movement of the circular blade.
    Remove the fiber holder with the cleaved fibre from the device.

    Place the fiber holder into the splicer.

    Fit the Alberino in the universal holder.

    To fit the Alberino in the universal holder make sure to match
    the point 1 with the point 2 (see picture A/B)
    - After, push down the functional cup (see picture C).

    Place the universal holder in the splicer and proceed with the
    splicing procedure.

                                                                      Marks on the screen

    Place the two fibers equally distant from the central reference
    line of the screen;
    please refer to the marks on the screen to obtain the desired
    distance (see a screenshot below). Then check the state of
    the fibers.

    This is the ideal case.
    Clean fibers with a good cutting angle (fibers perpendicular
    to the splicing axis).

                                                                         Approx. 1.5 x fiber diameter

    In case of slightly dirty fibers, press “PREFUSE" to clean them.
    Press several times if necessary until the fibers are OK. In case
    of too dirty fibers, the cleaning procedure must be repeated
    by removing the fiber holders from the fusion splicer.

    If the fiber of the Fusion alberino (the fiber on the left side of
    the display) is not OK, the Fusion alberino must be replaced.

    If the fiber to be spliced (the fiber on the right side
    of the display) is not OK, please repeat the fiber preparation
    and check your tools.

    If the fibers look OK, place the fibers for splicing and proceed
    as described.

    Move the fiber to be spliced by rotating the knob on the
    right clockwise until the cleaved end of the fiber is positioned
    as close as possible to the reference line in the center of the
    display.

    Move the Fusion alberino by rotating the left disc in the
    direction indicated on the picture until the cleaved end of the
    fiber touches the end of the other fiber. Be sure not to put any
    pressure on the fibers.

    Move the fiber to be spliced by turning the right knob by 2
    clicks in the direction shown on the picture. Pressure is exercised
    on the two fibers.

    Splice the two fibers by pushing the “SPLICE” button then
    check the splice quality. If the splicing is OK, the cladding
    surface is regular. If the splicing shows deformed areas as
    shown on the right, there could be the following causes of
    the incorrect splicing:

    -Insufficient quality of fiber surface.
    -unsuitable program number was chosen.
    -Dirt on the fiber surface.
    -Excessive or insufficient pressure on the fibers.

    After performing the splicing, perform the following operations:

    open the protection cover then press the mobile electrode
    support down, until it engages and make sure that it stays in
    this position.

    Place a protection layer over the electrodes so they are protected
    from eventual epoxy falling down.

    Mix a small amount of epoxy, mix the epoxy well with a mixing
    stick.
    The special quick epoxy glue pack Loctite 608 is split in two
    parts. Place the resin in one syringe and the hardener in
    another. In this way you may use the necessary quantity and
    the package will last longer.

    Prepare the ferrules to be mounted into their termini.

    Take the termini assembler (1074680) with the red point
    facing up.

    Press the lever and insert the termini by lining up the key
    with the red dot.

    Once the termini is half way in, release the lever and push the
    termini all the way till it clicks.

    Remove the cap from one ferrule being very careful not to
    bump its front face into the termini edges and damage it.

    Hold the fiber about 1,5 inches from the ferrule’s front and
    rotate it so that the key faces up.

    Carefully insert the ferrule into the termini until it clicks. If all
    the parts are properly aligned, the ferrule slides in and gets
    locked effortlessly.

    Push the termini assembler lever to release termini and fiber
    and pull them out.

     Put back the protective cap onto the ferrule.

     Repeat sequence for all 4 ferrules.

     At this point your ferrules should look like this.

     To remove the ferrules from the termini proceed as follows:
     Take the ferrule extractor (1074651).
     Slide the fiber in the instrument’s slit.

     Push the instrument into the termini until it clicks.

     Hold the fiber and pull the termini out as shown in the picture.
