Port 4 is connected to the micro switch chamber.
For this reason, pipes carrying gas must not be con-
nected to port 4!
If necessary, port 4 (1/8" NPT) can be used to connect
the venting line.
A filter pad at port 4 protects the electrical contacts in
the pressure switch from dirt particles in the surround-
ing air or in the medium.
