Perform Pressure Relief Procedure , page 13.

1.Plug sprayer into correct voltage, grounded outlet.

2.Turn the ON/OFF switch OFF wait 30 seconds and then turn power back ON again (this ensures sprayer is in normal run mode).

3.Turn pressure control knob clockwise 1/2 turn.

4.View digital display or remove control box cover to view control board status light. To determine which code (or any other code besides voltage supply) refer to the control board status light. Turn the ON/OFF switch OFF, remove the control cover then turn power back ON. Observe the status light. Blinking LED total count equals the error code (for example: two blinks equals CODE 02).

Keep clear of electrical and moving parts during troubleshooting procedures. To avoid electrical shock hazards when covers are removed for troubleshooting, wait 7 seconds after disconnecting power cord for stored electricity to dissipate.
