INSTALLATION

The E30 consists of two separate parts, the process connection and the electrical 
housing.  The two parts are locked together by an Allen screw located under the 
electrical housing.  As supplied, the two parts are separate allowing the process 
connector to be screwed onto pipework using a suitable 1/4” BSP pipe nipple (not 
included).   The provision of a separate process connector means the E30 can be 
easily installed in awkward locations  particularly when the tapping point is located 
close to pipe bends or other obstructions.  In effect, the process connection acts 
as a union and can be screwed onto a pipe nipple and  installed in the pipework.  
The electrical housing can then be 

fi

 tted onto the process connection and locked 

in place with the Allen screw.  

To lock the two parts of the E30 together, with the electrical housing located on 
the spigot and in position, press down with the 

fl

 at of your hand on the top face of 

the lid of the electrical enclosure.  While pressing down, screw the 4mm Allen 
screw fully through the housing using the 3mm Allen Key (supplied).  Tighten the 
screw and then release your hand from the top of the housing.   Pressing down 
with your hand on the housing preloads the O-ring seal between the housing and 
the process connection.  It enables the M4 Allen screw to easily screw fully through 
the side of the housing.  Do not screw the Allen screw through the housing without 

fi

 rst preloading the O-ring in the manner described above.  To do so will result in 

the Allen screw cutting a thread through the housing and reducing the designed 
preload against the O-ring.  This in turn will compromise the seal between the two 
parts of the pressure switch.
