LM4X/LMX-DPS User Manual
8
(supersonic wind tunnels) there are two gas fittings on the rear cover. Air lines can be connected to these
fittings to provide additional cooling where the atmospheric pressure is too low. Blue air lines of ¼” tubing
will fit these fittings. One end of the provided cooling-air lines has the mating connection to connect to the
air fittings. The other end has no connector. This end can be fitted to the appropriate connection for the
cooling air setup at the end use facility or it can be connected to the nut and ferrule that are on the back of
the LM4X housing. Input pressure to these cooling ports should be low,
just above ambient pressure. To
connect the nut and ferrule to the blue cooling air lines, fully insert the open end of the air line into the open
hole in the nut. Then, using a wrench, turn the nut 1 + ¼ turns. This will press the ferrule into place around
the tubing, making an air tight connection.

2 cooling air tubing lines are supplied with each LM4X LED module.
