4. Steam Damper Air System Connections
The dryer is manufactured with a pneumatic (piston) damper system, which requires an external supply of compressed
air. The air connection is made to the steam damper solenoid valve, which is located at the rear inner top area of
the dryer just in front of the electric service relay box. (Refer to the bottom illustration on the next page.)
a. Air Requirements
Shaded areas are stated in metric equivalents
b. Air Connection
Air connection to system – 1/4” Quick Connection
c. No air regulator or filtration is provided with the dryer. External regulation/filtration of 80 psi (5.51 bar) must be
provided. It is suggested that a regulator/filter gauge arrangement be added to the compressed air line just
before the dryer connection. This is necessary to ensure that correct and clean air pressure is achieved.
