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 tumbler spin time are adjustable by mode selection switches located on the
electronic timer (as noted in the
illustration below ).

L. COMPRESSED AIR REQUIREMENTS
This model dryer requires an external supply of compressed air (3.5 cfh at 80 psi [0.09 cmh at 5.51 bar] for gas
models and 4.25 cfh at 80 psi [0.12 cmh at 5.51 bar] for steam models). For steam models, compressed air is
necessary for the air (standard) operated steam damper. (No damper is provided with [optional] steam solenoid
valve.) On both the steam models as well as the gas models, compressed air is necessary/required for blower air
jet operation to clean lint from the impellor/fan (squirrel cage).
1. Air Requirements
a. Microprocessor Controller (Computer) Dryers
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)
must be provided. It is suggested that a filter/regulator/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.
