b.Air Connection
Air connection to system
c.No air regulator or filtration is provided with the dryer. External regulation/filtration of 80 PSI (5.51 bars) 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 insure that correct and clean air pressure is achieved.
5.Steam Damper System Operation
The
Diagram 1 shows the damper in the heating (open) mode, allowing heat into the basket (tumbler).
Diagram 2 shows the damper in the cool down (closed) mode, pulling ambient air directly into the basket (tumbler) without passing through the coils.
NOTE: With the dryer off or with no air supply, the steam damper is in cool down mode as shown in Diagram 2 (refer to the illustration on the following page).
