4. Steam Damper Air System Connections

In standard format, this dryer is manufactured with a pneumatic (piston) damper system, which requires an
external supply of compressed air. (Note: this dryer may be provided with an optional steam solenoid valve
in which case no steam damper system is provided.) 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.

Shaded areas are stated in metric equivalents

b. Air Connection

Air connection to system — 1/8” N.P.T.

c. Air Regulation

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.
