It is strictly prohibited to immerse the pulse signal line connector along with the injector into the ultrasonic pool for cleaning. Otherwise, the pulse signal line connector can be damaged easily.
ATTENTION: Make sure to turn off the ultrasonic cleaning switch on the left side of the machine after cleaning procedure.

Uniformity/Sprayability Test

Uniformity test is to find out the difference of the injectors injecting at the same working condition. This test can indicate the comprehensive influences on the injector caused by electrical nature, bore variation and clogging. Spray ability test is to inspect the spraying performance by observing the injectors.
Installing and testing procedures for injectors minimum injection pulse width among these injectors could be observed.

Backflushing
Backflushing is limited to the top-supply injector by connecting the backflushing connector under uniformity /sprayability test. Test solution enters from the outlet of the injector and flows out from the inlet during backflushing. Backflushing can wash away the dirt inside the injector and dirt attached to the filter.

Find the backflushing connector (and select a supporting “O” ring to install it on the connector) installed below the fuel separator;
Install the top-supply injector in reverse direction (outlet up, inlet down);
Select the corresponding coupling element under the injector according to the shape of injector;
Adjust the screws to fix the fuel separator and injector assembly in the fuel filler hole of the upper cover according to the height of injector and tighten the compression screws (black) on both sides evenly;
It is recommended to use manual switch to drain the remaining fuel in the transparent tube to avoid overflow of test solution before backflushing.
Connect the pulse signal line of the injector properly; set the operating parameters and press Run button to execute backflushing function; the system pressure can be adjusted by + and – buttons on the control panel during backflushing.
The system will stop automatically after completion of the cleaning.
