damper. The steam damper plate now covers the steam coil and allows room air to bypass the coil
before entering the basket (tumbler) for a rapid cool down.
The steam damper plate should open and close slowly and smoothly. This speed can be
modulated by adjusting the needle valve knob. Turning the knob clockwise restricts the compressed
airflow and slows down the steam damper movement. Counterclockwise adjustment speeds up the
steam damper motion. Upon completion of adjustment, tighten the needle valve’s locking nut.
