Overview
Air Control Module 26A231 provides electrical and air
connections to enable a ProMix PD2k Dual Panel pro-
portioner to operate two manual spray devices, as well
as, one or two gun flush boxes, or one or two air shutoff
valves. See FIG. 1 for the identification label.
Order Gun Flush Box Kit(s) 15V826 separately (see the
Gun Flush Box Kit manual). Each 15V826 Kit includes
one gun flush box and related parts. The pressure
switch included in Gun Flush Box Kit 15V826 will be
installed in this interface module.
Order Air Shutoff Kit(s) 15V823 separately (see the Gun
Air Shutoff Kit manual). Each 15V823 kit includes one
air cutoff valve and related parts.

Installation
Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
1. Relieve pressure from the air inlet supply before
connecting air to inlet (13) of the enclosure. See
Parts on page 8.
2. Follow the Pressure Relief Procedure in the applica-
ble manuals. See Related Manuals, page 2.
Location
Install the air control module enclosure (1) within 15 ft
(4.5 m) of the PD2K Dual Panel Control Enclosure, to
ensure that the cable (23) will reach between the two
enclosures.
Mount the Enclosure
1. See Dimensions, page 9.
2. Ensure that the wall and mounting hardware are
strong enough to support the weight of the equip-
ment, fluid, hoses, and stress caused during opera-
tion.
Using the equipment as a template, mark the mounting
holes on the wall at a convenient height for the operator
and so equipment is easily accessible for maintenance.
3. Drill mounting holes in the wall. Install anchors as
needed.
4. Bolt equipment securely.
The equipment mush be grounded to reduce the risk
of static sparking. Static sparking can cause fumes to
ignite or explode. Grounding provides an escape wire
for the electric current.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection or splashing
fluid, follow the Pressure Relief Procedure when
you stop spraying and before cleaning, checking, or
servicing the equipment. When turned off, all air
valves bleed to atmosphere.

Install the Cable
1. Loosen the captive screws and remove the front
cover from the enclosure.
2. The cable (23) has bare wires at both ends. Thread
the shortest end (4 in. [102 mm]) into the enclosure
through the strain relief bushing (7). See FIG. 2.
3. Connect the cable wires to the left side of the termi-
nal strip (12), as indicated by the label (37). See
FIG. 2 and Table 1.
4. Connect the other end of the cable (5 in. [127 mm])
to the appropriate terminal blocks of the EFCM in
the PD2K Dual Panel Control Enclosure. See FIG. 3
and Table 2.

Install the Pressure Switch
NOTE: The Air Control Module Kit does not include a
pressure switch (PS). The pressure switch is supplied
with the gun flush box kit. Install the pressure switch in
the interface module as follows.
1. Each gun flush box kit includes one pressure switch
(PS). The Air Control module can accommodate 1
or 2 pressure switches. Install the switch(es) in the
left side of the enclosure. See FIG. 4.
2. Connect the wires from PS#1 to the right side of the
terminal strip (12) pins 5 (+) & 6 (-), as indicated by
the label (38). See FIG. 5 and Table 1.
3. If using a second gun flush box, connect the wires
from PS#2 to the right side of the terminal strip (12)
pins 7 (+) & 8 (-), as indicated by the label (38). See
FIG. 5 and Table 1.

Connect the Gun Flush Box
NOTE: Use 5/32 in. (4 mm) OD tubing to connect the
gun flush box air ports to the interface module air ports,
as follows. See FIG. 7.
1. From the Pport to the air supply.
2. From the A port to the pressure switch air input.
3. From the C port to the gun flush box solenoid out-
put.
4. From the S port to the atomizing air safety shutoff
valve pilot port. See the gun flush box manual for
details on the safety shutoff valve.
5. From the AFS to the atomizing air safety shutoff
valve IN port. See the gun flush box manual for
details on the safety shutoff valve.
Connect Air Supply to Module
Connect a 1/4 in. (6 mm) OD tube between a clean, dry
air supply (filtered to 10 microns) and the module air
inlet fitting (13). See Parts on page 8.
Replace the Cover
Reinstall the cover on the enclosure and secure with the
four captive screws.
Ground the Enclosure
Connect a ground wire (Y) from the enclosure’s ground
screw (6) to a true earth ground. See FIG. 6.
