Recommended Guidelines for Maintenance/Service
When servicing a system, it is recommended to do these:
• Do the baseline service checks and verify the original setup values in this manual.
• Identify individual performance problems. Evaluate possible causes and corrections for
performance issues.
• Troubleshoot individual components and replace, if needed.
Important: The primary service tool will be a voltmeter that can measure voltage and resistance
(ohms).
Baseline Evaluation Process
1. Make sure that the voltage readings are correct.
2. Do a visual check of all wire connections, harnesses, and connectors. Make sure that there are
no loose, broken, or damaged parts.
3. Make sure that the correct tip size is used for the application.
4. Compare the current settings with those recorded in the manual during setup.
5. Make sure that the liquid product plumbing and the strainer(s) are clean.
6. Do a like component swap test to see if the failure follows the component.
7. Repair or replace any damaged components.
8. Do the system tests.
See the system testing information in this manual.
Strainers and Screens
Important: Clean the strainers on a regular basis.
Check the mesh size of the strainers and replace the screens if they are too coarse. Use 80-mesh or
finer strainer screens. The filter manufacturer is specified only on the strainer housing. Only a color
code identifies the strainer mesh size, which is not consistent between filter suppliers. An 80-mesh
screen is required to prevent nozzles from plugging. When selecting a strainer, do not rely on the
color coding. Check with the strainer manufacturer to be sure and select the 80-mesh strainer.
Plugged strainers will cause a reduction in system operating pressure.
When replacing the mesh screen on a Tee-jet Strainers:
1. Install and set the mesh screen in the strainer head.
2. Install the strainer cap.
Important: Failure to do this will likely result in a damaged mesh screen and overall strainer
failure.
