REVERSING TIMER SPIN/DWELL ADJUSTMENTS
Timer models have an electronic reversing timer in the electrical service box, which is located in the upper left
rear area of the dryer.
Both the Dwell (stop) Time and the basket (tumbler) Spin Time are adjustable by mode selection switches
located on the electronic timer (as noted in the illustration below).
M. COMPRESSED AIR REQUIREMENTS
Steam dryers require an external supply of compressed air, with a volume of 4.25 cfh @ 80 psi (0.12 cmh @ 5.51
bar, 551 kPa). Compressed air is necessary for the air operated steam damper.
1. Air Requirements
Shaded areas are stated in metric equivalents
2. Air Regulation
No air regulation or air filtration is provided with the dryer. External regulation/filtration of 80 psi (5.51 bar,
551 kPa) 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.
