Steam Damper Air Piston (Flow Control) Operation Adjustment
Steam damper operation was tested and adjusted prior to shipping at 80 PSI (5.51 bars). If steam damper
adjustment is necessary, locate the flow control valve and make the necessary adjustments as noted below.
Diagram 1 shows the damper in the heating (open) mode, allowing heat into the tumbler (basket).
Diagram 2 shows the damper in the cool down (closed) mode, pulling ambient air directly into the
tumbler (basket) without passing through the coils.
NOTE: With the dryer off or with no air supply, the damper is in the cool down mode as shown in
Diagram 2.
