ENCLOSURE
Vectronics has designed a matching enclosure just for your VEC-422K SCA
Decoder Kit. The matching enclosure is an all metal box which includes knobs,
hardware, decals, and rubber feet. Enclosure Model Number: VEC-422KC.
To install your decoder in the VEC-422KC matching enclosure follow these instructions
(read all instructions before beginning ... take your time):
1. Find the front panel decal and rear panel decal; separate using scissors. Be sure to
leave excess decal material around the edges. Put the rear panel decal on first. This
is done by: a.) Remove all debris and oil from the chassis. This should be done
using a piece of cloth and alcohol. b.) Remove the crack and peel to expose the
adhesive. c.) Place the decal on the rear panel without securing it completely. d.)
Gently rub the alignment circles with your finger--if the circles are centered in the
enclosure holes (also check the corner alignment marks) secure the decal by rubbing
and removing all air bubbles. e.) If the alignment circles are not centered, adjust the
decal accordingly then secure. f.) Use a penknife, or small Exacto
TM knife, to cut
away the unused edges (cut from the adhesive side) and cut out the component holes
(cut from the description side). g.) Repeat this procedure for the front panel.
2. Next, install the two L-brackets on the chassis using two of the 3/16" screws. The
longer side of the L-bracket must be connected to the chassis using the two holes
centered on each edge of the enclosure. Refer to the diagram on the next page for
location and orientation.
3. Install the two 1/2" mounting screws next. Insert the screws, from the bottom,
through the four holes relatively close to each corner of the chassis.
4. Place the two 3/16" round spacers on the mounting screws.
5. Now insert the PC board. This must be done by: a.) Remove the nuts and washers
from R16 and R17. b.) Insert the front of the PC board at an angle, so the controls
enter their respective holes. c.) Push down on the rear of the board. Make sure the
mounting screws align with the mounting holes in the PC board before pushing.
6. Use the two hex nuts to secure the PC board. Be certain all appropriate components
are centered with the enclosure holes before tightening. Put the washers and nuts--
removed from R16 and R17--back on and tighten.
7. Find the knobs and switch cap. Align the switch cap with SW1 and push it on. If it
is difficult to push on, then rotate it 90° and try again. Now put the knobs on R16
and R17. You may need to loosen the set screw. Align appropriately then tighten
the set screw.
8. Locate the piece of double-sided tape. This is to be used for holding the 9-volt
battery clip in place. Locate a place on the underside of the top cover where the
battery will not interfere with any components. Peel off the backing of the tape and
stick it to the chosen location, then install the battery clip.
9. The top should be installed next. Use the two remaining 3/16" screws for securing
the top to the L-brackets. Make sure the L-brackets are aligned properly.
10. Finally, place the four rubber feet on the bottom of the enclosure at the corners.
