Closing the Balance Assembly
After you have finished the procedures on the previous pages, lower the balance cover carefully over the
balance assembly and tighten the two screws as shown in
“Unpacking the Balance” on page 29
. Then place
the Autosampler cover over the tray.
The installation procedure is now complete. However, since the balance housing has been opened during
this installation, balance conditioning is required.
Balance Conditioning
Balance conditioning is required for the Discovery TGA in order to achieve optimum performance from
your instrument and keep the balance housing dry. Perform a balance conditioning when:
•
The instrument is first installed
•
Whenever the balance housing is opened
•
Whenever the instrument is powered off for an extended period of time.
For more information related to conditioning the balance, see
“Conditioning the Balance” on page 63
detailed instructions.
Filling the Heat Exchanger Reservoir
The heat exchanger contains a liquid reservoir that supplies the instrument with coolant to dissipate heat
from the furnace. The coolant exits the heat exchanger through the supply line, circulates to the furnace,
and returns to the reservoir via the return line. To fill the heat exchanger, follow the directions given below.
For instructions on how to connect the water lines, see
“Connecting the Heat Exchanger Cable and Water
.
1
Disconnect the heat exchanger control harness and water lines from the instrument cabinet.
2
Unscrew and remove the water reservoir cap.
