To replace or reinstall the EGA furnace:
1. Plug the AIR COOL line into the bottom of
the furnace arm/base as shown in Figure D.5
on page D-11.
2. Slip the water cooling hoses over the EGA
furnace water connections and secure them
with the wire ties.
3. Tighten the upper two mounting screws
fully, then loosen each of them no more than
one full turn, so that the flat sides of the
cleats are aligned vertically as shown in
Figure D.4 on page D-10.
Now tighten the lower two mounting screws
fully, then loosen each of them two full
turns, plus a fraction of a turn, so that the
flat sides of the cleats are aligned vertically
as shown in Figure D.4 on page D-10.
Loosening the upper two mounting screws
any more than one full turn may cause the
screws to interfere with the inside of the
instrument cabinet, causing damage to the
instrument.
4. Press the FURNACE key to raise the
furnace carriage until the lower mounting
screws are just below the top edge of the
enlarged cutout in the instrument faceplate.
Then press the STOP key.
