7.7 SHUT DOWN AFTER USE (FLUSHING)
PRO/pak should be flushed with water after each use to prevent agent concentrate from drying out inside of the Control Block and
Percentage Knob.
1. Reduce pump pressure to 100 psi or less.
2. Remove the nozzle and/or hose from the quick-connect on the front of the Control Block.
3. Remove the Circle Cotters and pull out the two Pull Pins that hold the Control Unit to the tank.
4. Pull straight up to remove the Control Unit and Pickup Tube from the tank.
5. Make sure the Percentage Knob is NOT in the RINSE position.
6. Install the Cap on the outlet of the Control Block.
7. Turn the Flow Control valve until a trickle of clean water is flowing from the end of the Pickup Tube.
8. Turn the Percentage Knob back and forth to make sure all agent passages are flushed.
9. Shut off water and reinstall the Control Unit on the tank and insert the Pull Pins and circle cotters.
10. Remove the Cap.
The exterior of the PRO/pak can be washed off with the hose or straight stream nozzle, with the percentage knob in the OFF position.
7.8 STORAGE
The PRO/pak can be stored with agent concentrate in it. Make sure the
control block and valve assembly is mounted on the tank and the fill
port is securely closed to prevent evaporation. Storage in the upright
position is recommended to avoid agent leaking when the PRO/pak is
not in use.
