Installation
For packing purposes the Sample Concentrator is supplied unassembled in three parts; the base board, the column
and carriage, and the gas chamber. The unit is re-assembled as follows:
1. Unscrew the column fastening knob from the column support bracket already fixed to the base board.
Locate the column on the two pins in the support bracket. Screw the fastening knob through the rear of the
column and tighten firmly.
2. Align the threaded hole on the back of the gas chamber with the mounting on the carriage. Tighten the
locking knob to secure the gas chamber in position.
3. Connect the intake nozzle at the rear of the gas chamber to a suitable supply of gas via a pressure reducing
valve. The gas pressure should be adjusted as required at the reducing valve but should not exceed 2 psi.
Pressure in excess of 2 psi will cause gas to be vented and wasted.
4. Place the Techne Dri-Block
®
heater onto the base of the Sample Concentrator. It is positioned by means of
two spigots on the base board which align with two centrally located screw heads on the underside of the
Dri-Block
®
unit.
