Important
Flexible hoses/couplings must be used. Coil
failure due to hard plumbing connections will void
the warranty.
Steam Damper Air System Connections
This 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.
Air Requirements
There is no air requirement for dryers with the
electromechanical steam damper option.
Shaded areas are stated in metric equivalents
Air Connection
Air connection to system — 1/8” N.P.T.
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.
