Page 40
5. Steam Damper System Operation The steam damper, as shown in the illustration below, allows the coil to stay constantly charged eliminating repeated expansion and contraction. When the damper is opened, the air immediately passes through the already hot coil, providing instant heat to start the drying process. When the damper is closed, ambient air is drawn directly into the basket (tumbler), allowing a rapid cool down.
Page 41
6. 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. NOTE: Adjust both flow control valves equally, so that both pistons operate at the same time.
J. PREOPERATIONAL TESTS ALL dryers are thoroughly tested and inspected before leaving the factory. However, a preoperational test should be preformed before the dryer is publicly used. It is possible that adjustments have changed in transit or due to marginal location (installation) conditions. 1.
