Clear Tip Clogs - Graco SaniSpray HP 20 Operation - Repair - Parts

How to Spray
•
Make certain the Cup Lid is properly
threaded to the Cup Support. If threads
are visible below the Cup Lid when tight,
then the cover is cross-threaded. Fully
remove the Cup Lid and reinstall to the
Cup Support so no threads are visible
when tight.
•
Repeat steps 6 – 8 on pages 14 – 15 to
ensure all the air is evacuated from the
FlexLiner.
•
Make certain the Spray Tip is not
clogged. See Clear Tip Clogs, page 18.
•
If sprayer sprays disinfectant while
holding sprayer upside down, there is air
in the cup. See Starting a New Job,
page 13, steps 6 – 8.
•
Replace VacuValve Cap. Two new
VacuValve caps came with your sprayer.
•
If sprayer still does not spray, see
Troubleshooting, page 25.

Clear Tip Clogs

To avoid injury, never point sprayer at your
hand or into a rag!
In the event debris clogs the Spray Tip, the
sprayer is designed with a reversible Spray
Tip that quickly and easily clears the particles
without disassembling the sprayer.
1. To unclog Spray Tip, turn Prime Knob
downward to PRIME position.
2. Reverse Spray Tip to UNCLOG position.
3. Set Speed Control to 10.
