Frequently Asked Questions

Check your sprayer’s exact model number and serial range in the official parts manual. Confirm the pressure control assembly part number listed there matches 24X289 (or that 24X289 supersedes your current part).

Erratic pressure, surging, inability to hold set pressure, frequent over- or under-atomization, or a knob that has little/no effect on output are common signs the pressure control assembly needs replacement.

Many references list 24X289 as the updated kit for older numbers like 249005 and 255169. Always verify by model/serial in the parts manual to be certain for your specific unit and region/voltage.

The kit is commonly referenced with a 3300 PSI system rating, but you should never exceed the rated working pressure of your sprayer model. Start low and verify stable control through your normal operating range.

Keep electrical connections clean/dry, avoid pressure spikes, and address pump/packings wear promptly—unstable hydraulic load can shorten the life of the pressure control assembly.
