WARNING
First-Time
Installation
D–6
Make sure that you place the heater power
switch in the off position before removing
or installing the furnace on the TGA 2950
instrument.
Version 3.3B (or higher) of the TGA 2950
instrument software is required for the EGA
furnace.
The first time that you install the EGA furnace
involves the removal of the standard TGA
furnace and replacement of the four furnace
mounting screws and cleats with those supplied
with the EGA furnace.
After this has been completed according to the
following directions, you may interchange the
two types of furnaces without changing the
mounting hardware. Refer to page D-13 "Re-
moving and Reinstalling the EGA Furnace" for
subsequent furnace exchanges.
1. Place a drip pan to the left of the instrument
to catch the coolant that will leak from the
hose connections when the standard furnace
is removed.
2. Remove the standard TGA furnace using
steps 1 through 5 found in Chapter 5 "Re-
moving and Reinstalling the Furnace."
