4.10 2" Purge Exhaust Switching Valve Maintenance

(Model LS1250 only)

WARNING!

Ensure that the Dryer is de-energized, valve isolated, and fully depressurized before attempting to remove or disassemble any Dryer component or subassem- bly. Failure to do so may result in serious personal injury and/or equipment damage.

Note: Removal of valve body [16] from the dryer manifold is not required unless replacement of square O-rings [17] or valve body is necessary.

Note: Exploded view illustrates one-half of switching valve only. Disassembly of opposite half (not shown ex- ploded), is identical.

1.Clean and inspect all valve hardware upon disassem- bly. Replace all software and any hardware which appears damaged or abnormally worn.

2.Clean and inspect valve seat located inside the valve body [16]. As previously noted, this can be accom- plished without removing the valve body [16] from the dryer manifold.

3.Apply an ultra-thin film of O-ring lubricant to items [3], [5], [8], [11], and [17] before reassembly. Do not ap- ply lubricant to the valve seat seal [13].

4.The U-cup piston seal [5] has been fitted with a cut O- ring. Ensure that the U-cup piston seal is installed on the valve piston [4] as shown. The open side of the U-cup piston seal [5] must face the valve cover [2] upon reassembly.

5.Apply a light coat of lubricant to the sockethead cap screws, items (1) and (18). Hand tighten screws until snug. Torque to 245 in-lbs.
