TUBING CONNECTION 

 

 

When the MPC Series Panel Mount MFC is panel-mounted, use tubing that does not stress the MFC 
housing.  If metal piping is directly connected to the 1/8” FNPT connector of the MFC, the MFC 
should not be panel-mounted. 

 

Connect the tubing to ensure the gas flows in the direction from ‘IN’ to ‘OUT’ as indicated on the 
housing. 

 

After connecting the tubing, check for any gas leaks.  While performing the leak check, exercise 
caution to avoid spillage or contact of the leak detection fluid to the housing, electrical wiring or 
mating electrical connector.  If fluid contact occurs, MFC malfunction or faulty operation may occur. 

 

EXTERNAL ELECTRICAL CONNECTIONS 

 
Prior to wiring, confirm: 

 

Power supply source is off prior to wiring connection. 

 

Wiring is correct prior to introducing power. 

 

The event output does not exceed the specified output rating of the MFC.  When driving a relay, 
use a relay with a built-in diode for coil surge suppression.
