Replacing the Desiccant Wheel
Assembly
(D1300 - 5000)
If you need to service the desiccant wheel assembly (wheel, motor, belts, etc.), use the fol-
lowing procedure to remove the entire assembly from the dryer.
1 Stop the dryer, disconnect and lockout the main power.
2 Remove the upper and lower side panels from both sides of the
dryer.
3 Remove the top cover from the dryer by removing the securing bolts.
4 Note the position of all the hoses, RTDs, and wiring connections then remove or
disconnect these from the desiccant wheel assembly.
5 Remove the bolts securing the desiccant wheel assembly to the dryer frame.
6 Note the orientation of the desiccant wheel assembly. Using an overhead crane or
similar device, use the lifting rings provided and lift the desiccant wheel assem-
bly out of the dryer.
To replace the wheel assembly, reverse the procedure above.
NOTE: If your dryer is configured with a hard pipe kit, disconnect the hard piping from the top of the
dryer at this time.
