EN EN 05. PRODUCT OVERVIEW
05.1 GUN FLUSH BOX
Gun flush boxes operate with higher solvent and air
pressures. These pressures improve flush efficiency,
while gun flush boxes improve safety and minimize
solvent usage. They also save time compared to manual
spray gun flush procedures.
Up to two guns can be used on the IntelliFlow system.
The standard setup includes one flush box per gun
for optimal performance. In two-gun installations, the
system controller typically operates Gun #1 and Gun #2
with individual flush boxes for loading and flushing. A
single flush box can be used for both guns if configured
accordingly. This setup is not typical and should only be
used when specifically configured. Gun #2 can also be
disabled by the administrator if necessary.
The Gun Flush Box Kit operates with RM2, RF2 and
RF2+ systems. This manual has separate sections for the
pneumatic connections of the gun flush box to the RM2,
RF2 and RF2+.
All pneumatic connections to the gun flush box are
engineered for 5/32 (4mm) OD tubing.
The RM2 directly connects to the gun flush box, but it
is necessary to install Air Cut-Off Kit 310-3905-XX (sold
seperatly) before it can be connected to the gun flush box
kit. Installation instructions for the Air Cut-Off Kit-to-RF2
and RF2+ can be found in RF2 manual 77-3152-1 and
RF2+ manual 77-3165-1.

06.9 GUN SADDLE ADJUSTMENT
The gun saddle is the plastic part inside the box that
cradles the spray gun’s front end to ensure proper box
operation. Install the gun saddle for the specific model of
spray gun to be used.
1. Insert two 5/16-18 screws through the spacer and
into the gun saddle to secure it to the side wall of the
gun flush box.
2. Put the gun in the saddle as shown. Try to shut the
lid. If the lid does not fully close, use the two screws
to adjust the height of the gun holder until the lid
correctly closes.
3. Make sure the gun trigger actuator pin engages the
finger side of the spray gun trigger when the lid is
closed. If it does not engage, the holder must be
adjusted.
4. The bottom of the gun saddle has 2 (50.8 mm) NPT
female threads for connection to a 2 (50.8 mm)
metal waste drain pipe with mating threads.

06.10 SADDLE ADJUSTMENT STEPS
1. To correctly adjust the gun saddle in the gun box, the
applicable saddle must be installed for the gun to be
used.
2. Remove the 5/16-18 cap screws on the right side to
put the gun saddle into the gun box.
3. Turn in the new gun saddle, and leave the screws
loose for adjustment.
4. Put the gun into the holder and bring the gun up to
the actuator pin. The pin must be under the gun
trigger.
5. Tighten the screws on the right side of the gun box.
6. Set the gun handle adjustment until it is clear of the
gun controls on the back of the gun.
7. Close the gun box lid. The box is ready to use if the
lid triggers the air output Gun in Box (GIB) signal. If
the lid does not trigger the air output Gun in Box
(GIB) signal, continue to steps 8-10 below.
8. Adjust the actuator pin location, pull it up, and tighten
its screws.
9. To access the screws to the actuator pin, remove the
four screws on the left side of the gun box and
remove the air connection enclosure part of the box.
10. Loosen the two screws on the actuator slide block
and move them up or down, dependent on the gun’s
size and shape. Tighten the screws.
11. Repeat steps (4 to 10) until the gun box GIB output
operates. The gun box is now ready to use.

EN EN 07. OPERATION
DANGER
The voltage must be turned off to clean and flush an electrostatic applicator. Failure to adopt and follow this procedure
can cause a fire and/or explosion.
CAUTION
The gun flush box must be enabled in the system software configuration.
The IntelliFlow system will NOT operate the gun flush box until software configuration is correct.
With the flush box mounted, the pneumatic tubing connected, and the saddle correctly adjusted for operation:
1. Open the valve or regulator to supply the AIR inlet of the flush box with 75-100 psi (5-7 bar) air.
2. Start the IntelliFlow system and adjust each gun’s flush time and load volume to optimize the flush and load
procedures.
3. Place the spray gun in the box and close the lid. Atomizing air will exhaust through the ACO valve, and the
actuator pin will extend to the front of the gun trigger.
4. Select the Color Change screen on the IntelliFlow system, then prepare the desired paint color load. The system
will do the applicable flush/load sequence. To change color, refer to RF2+ Operation Manual 77-3165-2 or RM2
Operation Manual 77-3153-2 for more detail.
5. When the paint load is complete, the system will return to the home screen and make a sound. The AE valve will
then close.
6. Open the gun flush box and remove the spray gun. Close the gun flush box lid. The gun is now ready to spray.
7. When the spray operation is complete, open the gun flush box lid. Put the gun back into the box, then close the lid.
8. If necessary, select the color change screen on the IntelliFlow system to flush or load the next color. Pot life will
continue to count down until it expires or a flush is done.
