1. With power removed from the balance, remove any draft shield or draft shield
glass panels, the pan, pan support and any wind ring or adapter ring (sizes and
shapes vary) to fully expose the EMC plate on the top of the balance.
2. Remove the 2 screws and the EMC plate.
NOTE: On some models with angular wind rings, be careful not to lose the 4
corner plastic locating pins where the EMC plate slots over. These are marked
"F" (front) or "B" (back) with the markings facing inwards (note their positions in
case dislodged and needing to be re-installed).
3. Disassemble the top from the bottom housing (depending on model):
a) Small frame models: Remove the 4 feet, then remove the 4 screws inside
the openings uncovered by the removal of each foot.
NOTE: While removing the feet, avoid resting the balance on its top side
(over the load cell cone assembly). If needing to do so, place the
protective plastic cone cover from the kit over the load cell cone assembly
to minimize risk of damage to the load cell (See Figure 2A).
b) Large frame models: Remove the 2 screws (and any grounding clip) on
the top of the balance that were exposed by the removal of the EMC plate.
NOTE: If the balance was trade approved, any sealing sticker covering the
housing screws will need to be removed. In effect, the balance will have to be
re-approved and re-sealed.
4. Carefully lift the top cover from the bottom housing, mindful of the cable
connected to the main PCB assembly.
5. Unplug the cable from the main PCB assembly, then set aside the top cover.
6. Remove the 2 screws securing the COM2 cover plate towards the back and
right of the bottom housing (See Figure 2B). Discard the cover plate and 2
screws.

7. Mount the 2
2 screws provided (See Figure 2C).
8. Connect the PCB cable to a) the 2
the main PC board on the front of the balance (see Figure 2D). Route the PCB
cable towards the left side of the bottom housing.
9. Re-assemble the balance in the reverse order of the disassembly process,
being careful not to pinch any cables within or between the top and bottom
housing.
