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.
