Furnace Installation - TA Instruments TGA5500 Getting Started Manual

Lay the furnace assembly down on the left side of the instrument so that the hose connections are posi-
tioned over the drip pan. Then carefully snip the wire ties and disconnect the cooling water lines from the
housing. (A small amount of cooling water will drain out into the pan when the hoses are disconnected.)
The furnace is now completely free from the instrument.

Furnace Installation

To replace or reinstall the Wire-wound or EGA furnace use the following procedure. Refer to the figures
on previous pages, if needed.
1 Plug the AIR COOL line into the bottom of the furnace arm/base.
2 Slip the water cooling hoses over the furnace water connections and secure them with the wire ties.
3 Tighten the 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.
CAUTION: 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.
MISE EN GARDE: Desserrer les deux vis supérieures de fixation plus d'un tour complet peut
entraîner les vis d'interférer avec l'intérieur de l'armoire de l'appareil , causant des dommages à
l'instrument .
4 Plug the furnace arm into the connector on the carriage and tighten the four mounting screws using the
ball driver. To reach the upper left mounting screw, insert the ball driver between the water and air
connections on the left side of the furnace housing.
5 Connect the purge hose to the gas purge inlet on the right side of furnace.
CAUTION: Hold onto the glass purge tube with one hand while you install the purge hose to avoid
breaking the glass on the EGA furnace.
MISE EN GARDE: Tenez le tube de purge de verre avec une main pendant que vous installez le
tuyau de purge pour éviter de casser le verre sur le four EGA.
