The Generator is designed for indoor use only.
The unit should be installed adjacent to the Mass Spectrometer it is supplying. If this is not convenient
then the unit can be sited elsewhere, however, consideration should be made of the lengths of pipe
runs as pressure drops can result from extended runs of pipe. Please see the “Useful Information”
section for further details.
Performance of the generator (like all sophisticated equipment) is affected by ambient conditions. Note
should also be taken to the proximity of Air Conditioning outlets. These can sometimes give rise to
“pockets” of air with high relative humidity. Operation of the unit within such a pocket could adversely
affect its performance. Consideration should also be given to the air flow around the unit. It is
recommended that an air gap of 75mm (3”) should be maintained down both sides, at the rear and
across the top of the unit. Please refer to the drawing below for the general dimensions of the unit.
Maximum Ambient Conditions: 25°C (dry bulb) 70%RH (Max)
General Dimensions
Unit must always be placed on a level surface. Failure to do so will effect the
performance of the Generator.
