INSTALLATION

 

 
3.01  GENERAL 
 
The Signal NOXGEN III comes in a 19” rack type, 3 units high enclosure.  It can 
be bench top used or fitted into a 19” rack console.  For bench top use there are 
extendible feet at the front which can be used to tilt the angle of the instrument 
back for ease. 
 
When using this instrument in a 19” rack, the feet will need to be removed.  To do 
this, undo the 4 cross-head screws on the under cover and slide back the cover 
to remove it.  With the cover removed you can easily unscrew the four feet before 
replacing the cover for installation. 
 
This instrument is fitted with Parker CP1 stainless steel tube fittings.  Because of 
the presence of nitric oxide, nitrogen dioxide and ozone, all of which are toxic 
gases, great care should be taken to ensure that no leaks occur throughout the 
tube work.  Make the compression fittings off in accordance with the 
manufacturers recommendations and do not over-tighten the nut.
