Installing the Extraction System to the Laboratory Exhaust System
The GTA viewing/fume extraction accessory is connected to the
extraction duct using an adaptor plate. Two plates are supplied with
the accessory: use the longer one if you have a 150 mm (5 in.) duct
and the smaller one if you have a 125 mm (5 in.) duct. If your duct is
a different size, contact your local Agilent field service engineer.
Leave a 2–3 mm gap between the
furnace and the rim of the
accessory.
