3)Adjust the bottom heat reclaimer nuts down to their desired positions to obtain the proper piston stroke.

Example: If the desired piston stroke is 2-inches (5.1 cm), then the distance "X" in the

illustration below must be 2-inches (5.1 cm).

4) Tighten the top heat reclaimer nuts down onto the bottom heat reclaimer nuts.

Intake Air Damper/Cool Down Damper - steam model dryers require the use of both an intake air damper and a cool down damper. During the heat cycle, the intake air damper is opened to allow fresh air to be drawn across the steam coils. On the cool down cycle, the inlet air damper closes and the cool down damper opens. This draws fresh air into the tumbler (basket) section exhausting ALL of the 13,000 cfm (368 cmm) airflow, which insures a fast cool down of the load. (Refer to the bottom illustration on page 66.)

a.Intake Air Damper Replacement

1)Discontinue electrical service to the dryer.

2)Discontinue the air supply to the dryer.

3)Remove the character panel on the right hand side of the dryer - the 464 perforated panel - to access the pneumatic piston of the air intake damper.

4)Remove the two (2) 1/4" poly x 1/4" M.P.T. connectors from the piston.

5)Remove the C-clip from one end of the 1/2" clevis pin.

6)Remove the 7/16-20 clevis rod from the piston.

7)Remove the piston from the piston support.

8)To install new intake air damper piston, reverse Step #8 thru Step #3.

9)Reestablish the air supply to the dryer.

10)Reestablish electrical service to the dryer.
