(THE FOLLOWING IS TO BE PERFORMED DAILY OR AS NEEDED.)
1. Drain unit by placing switch in the off/drain position.
2. Open the door and allow the unit a few minutes to cool off.
3. Remove the pin holding the rinse feed pipe. Pull the feed pipe out of the nipple and lay it to one
side.
4. Remove wash head assembly by pulling out the holding pin and lifting assembly. Place the wash
head on a table for disassembly.
5. Locate Allen head set screw in the wash head cap, insert Allen wrench and loosen screw by turning
counterclockwise.
6. Turn wash head cap counterclockwise until cap is removed and put cap in safe place.
7. Remove
1/4
"
stainless ball bearings carefully and put it in a receptacle in a safe place.
8. Lift and remove small manifold with short tubes. Put it in a safe place.
9. Remove
1/4 " ball bearing in similar method to step #7.
10. Lift and remove large manifold with large length tubes similar to step #8.
11. Clean ball bearings by soaking in de-liming solution.
12. Ball bearing race ways may be cleaned by either brushing with de-liming solution
(toothbrush makes excellent tool) or gently clean by rubbing with fine sandpaper or emery cloth.
13. Rinse ball bearings and manifolds thoroughly.
14. To reassemble, first fill lower race to capacity with
1/4 " ball bearings, then remove one. This will
give proper movement needed during rotation of assembly.

16. Replace upper manifolds and repeat necessary parts of step #14.
17. Replace wash cap by screwing on center shaft clockwise, finger tight.
18. Back off wash cap about
1/4 turn and tighten Allen set screw.

8"
and no more
than 1/4"
.
