1. Start by transferring the cables from the old display card
to the new card. Start with connection G1 and then
transfer all cables of terminal G.
When all cables have been transferred, there will be four
spare connections at the top of the terminal (G17-G20).
2. In the same way, transfer the cables of terminal F from
the old display card to the new card.
Start with connection F1 and then transfer the other
cables. Connection F9 will then be empty.
3. Remove cable 11 from the defrosting device and attach
it to connection F9 on the display card.
4. Remove cable 16 from the defrosting device and
attach it to connection 8 of terminal X1 (cable 12 is to
be removed from the terminal and from the defrosting
device).
5. Remove cable 103 from the defrosting device and
attach it to an active ground connection.
6. Connect the defrosting sensors to the display card
terminal G17-G18 (sensor 1) and G19-G20 (sensor 2)
and then in the evaporator. Use the clips that come
with the delivery to attach the sensors in the evaporator.
Position the sensors, depthwise, in the middle of the
evaporator. Attach the sensors 200 mm from the right
hand side (seen from the front) and 200mm from the
bottom edge and the upper edge respectively.
