; page 13.
1.
Plug sprayer into correct voltage,
grounded outlet.
2.
Set power switch OFF for 30 seconds
and then ON again (this ensure sprayer
is in normal run mode).
3.
Turn pressure control knob clockwise
1/2 turn.
4.
View digital display.
To determine error code for units without
display, 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 5 minutes after unplugging power cord
for stored electricity to dissipate.
