Installation (Model 24H989)
2. Connect a 5/32 in. (4 mm) OD air supply line to the
air outlet fitting of the flow control module (FC). Con-
nect the other end of this line to the air inlet fitting of
a remotely mounted fluid regulator (FR).
Installation (Model
24H989)
The intrinsically safe flow control module (FC) is
required to use flow control in your system. It is for use
with a remotely mounted, air-operated fluid regulator
3. Connect a fluid line from the proportioner to the fluid
inlet of the remote fluid regulator (FR).
4. Connect a fluid line from the outlet of the fluid regu-
lator (FR) to the 1/8 npt(f) inlet of the pressure sen-
sor (PS).
1. Connect a 1/4 in. (6 mm) OD air supply line to the
air inlet fitting of the flow control module (FC). Con-
nect the other end of this line as follows:
5. Connect a fluid line from the 1/8 npt(f) outlet of the
pressure sensor (PS) to the spray gun inlet.
a. Wall Mount Systems: Connect to the air mani-
fold at the rear of the wall mount fluid station.
6. Connect the pressure sensor cable to the cable con-
nector on the flow control module (FC).
b. RoboMix Systems: Install a 1/4 in. (6 mm) OD
tube tee at the air logic inlet of the RoboMix.
Connect the flow control air line to one branch
of the tee and the main air line to the other
branch.
7. See the Electrical Schematic in your ProMix
instruction manual. Connect the flow control cable to
the fluid station control board and to the cable con-
nector on the flow control module (FC).

Before Servicing
Servicing the Regulator and
Pressure Sensor (Model 249849
only)
Regulator Service Kit 15G843 is available. Kit parts are
marked with an asterisk, for example (602*). For best
results, use all parts in the kit.
NOTICE
To avoid damaging circuit board when servicing, wear
Part No. 112190 grounding strap on wrist and ground
appropriately.
1. Flush system and follow Pressure Relief Proce-
dure in your ProMix Repair-Parts manual.
Sensor Service Kit 15G867 is available to service the
pressure sensor only. Kit parts are marked with a sym-
bol, for example (602‡). For best results, use all parts in
the kit.
2. Close main air shutoff valve on air supply line and
on ProMix.
3. Shut off power (0 position). FIG. 3.
4. Shut off power at main circuit breaker.
2. Remove the four screws (605) and the nut (601)
from the underside of the air plate (607). Separate
the air plate and fluid plate. FIG. 4.
3. Unscrew the pressure sensor (620) from the fluid
plate (606).
0 = OFF
NOTE: If you are only replacing the pressure sensor
kit 15G867, skip to step 6.
4. Remove the plug (615) and o-ring (604) from the top
of the fluid plate (606). Remove the parts of the dia-
phragm assembly (613, 610, 609, 612, 617, 616).
Remove and discard the dowels (623).
TI12657a
5. Reassemble the diaphragm assembly using the new
parts from the kit. Be sure the AIR SIDE of the dia-
phragm (617) faces down. Torque the nut (601) to
8-10 in-lb (0.9-1.1 N•m).
FIG. 3: Power Off
5. Disconnect all air and fluid lines from the flow con-
trol module.
6. Install a new o-ring (602) on the pressure sensor
(620) and screw the sensor into the fluid plate (606).
6. Model 24H989 only: Disconnect all fluid lines from
the pressure sensor fitting (626).
7. Reinstall the fluid plate on the air plate. Be careful
not to pinch the pressure sensor cable. Torque the
screws (605) to 30-40 in-lb (3.4-4.5 N•m).
7. Disconnect the flow control cable from the flow con-
8. Reconnect the three cables to J1, J2, and J4 on the
circuit board (618). FIG. 6.
After Servicing
After servicing, be sure to follow the Start Up checklist
and procedure in the ProMix Operation manual.
9. Reattach the air plate (607) to the housing (611).
Torque the screws (605) to 30-40 in-lb (3.4-4.5
N•m).
10. Reattach the flow control cable and all air and fluid
lines.
