4. Steam Damper Air System Connections
The MLS-55 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.

c. No air regulator or filtration is provided with the dryer. External regulation/filtration of 80 PSI (5.52

compressed air line just before the dryer connection. This is necessary to insure that correct and clean
air pressure is achieved.
