connector marked P2. On this same display board, the connector marked P6 should have a red
and white power jack cable plugged into it, and the connector marked P3 should have a 9-pin
ribbon cable connected to it. All three of these connections are necessary in order for the Setra
balance to function.
6. Position the balance so that the pins on the platform support plate are directly beneath the four
tube ports in the bottom of the furnace chamber.
7. Open the furnace door. Insert the four ceramic support tubes through the tube ports located in the
bottom of the furnace chamber. Adjust the position of the balance until the four ceramic support
tubes are seated on the appropriate pins on the balance plate. Finely adjust the position of the
balance until the tubes are centered in their ports, but not touching the sides of the ports.
8. Place the 10" x 11" gray silicon carbide hearth tray on the four ceramic support tubes with the

11" dimension from front to back. Position the front of the hearth tray about one inch back from
the lip of the bottom element plate. Center the hearth tray on the four support tubes, equally
distant from side to side.
9. Close the lower case by returning the control panel to its original position. Secure the control
panel with the four screws you removed in step 1.
10. Switch the main circuit breaker (located on the lower left rear corner of the case when facing the
front of the furnace) on. Close the furnace door and switch the power switch “on”. The balance
display board will read 0.0 grams after approximately 20 seconds of initialization. Turn power
“off” and reposition the balance if the display is unstable or reads anything other than 0.0 grams.
Instability may be caused by one of the support tubes rubbing.
