Bakeout procedure
The standard ALM-133/PNM feedthrough must be dis-assembled for bakeout.
Dis-assembly Procedure:
Actuate cylinder to the “out” position.
Insert two 1/8” OD by approximately 1” long pins through the two lock pin holes into the holes in the traveling head assembly.
Disconnect supply air and power to the control valve.
Remove three flat head screws (A) and gently pull back on the cylinder assembly, allowing the cylinder shaft to extend, while not
allowing the lock pins to be dislodged. Continue to support the cylinder assembly through the rest of the dis-assembly
procedure.
With an open end wrench, loosen the lock nut on the end of the cylinder shaft.
By hand, unthread cylinder shaft from traveling head assembly and remove the cylinder assembly.
Proceed with bakeout with lock pins in place.
Automatic temperature control with the sensor (s) correctly located in the top of the area being heated is highly recommended.
Re-assembly is the reverse of the removal procedure.
We recommend a maximum bakeout temperature of 200 degrees C.
