Installation
Installation
Install Color Change Control Module
• To avoid electric shock, turn off equipment power
and shut off power at main circuit breaker before
installing.
• All electrical wiring must be done by a qualified
electrician and comply with all local codes and
regulations.
• Do not substitute system components as this
may impair intrinsic safety.
To reduce the risk of serious injury, including fluid
injection, relieve pressure before installing the kit.
Follow the Pressure Relief Procedure in the
ProMix 2KS Operation or Service manual.
Location
Install the color change control module (101) near the
fluid station. The module is approved for use in a hazardous location. Also see your system installation manual. See F
IG. 1.
Mounting
1. See Dimensions, page 24.
2. Ensure that the wall and mounting hardware are
strong enough to support the weight of the equipment, fluid, hoses, and stress caused during operation.
3. 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.
4. Drill mounting holes in the wall. Install anchors as
needed.
5. Bolt equipment securely.

Connect Module to Fluid Station Board
NOTICE
To avoid damaging circuit board when servicing, wear
grounding strap on wrist and ground appropriately.
1. Remove the Fluid Station cover.
Installation
2. See F
IG. 1. Connect a 5-pin electrical cable (EC)
from the labeled connection port
(J11) on the
fluid station control board to the color change board.
Also see F
IG. 2 and FIG. 5.
NOTE: See Table 1 for a list of available cables to connect the color change control module and fluid station.
Recommended length is 3 ft (1.0 m) or 6 ft (2.0 m).

Connect Air Supply to Control Module
Connect a 1/4 in. (6 mm) OD tube (13) between the system’s air manifold (at the bottom rear of the fluid station)
and the module air inlet fitting (29). See F
The air supply must be clean and dry. Use a 5 micron filter. Regulate the air pressure to 75-100 psi (0.52-0.70
MPa, 5.25-7.0 bar).
IG. 3.
If you are using two color change modules to add colors,
connect a 5-pin electrical cable from the first color
change board to the second color change board. See
F

Connect Valve Air Lines
See FIG. 1. Connect 5/32 in. (4 mm) OD air tubes (11)
from the valve solenoids to the air inlets of each valve.
Refer to the System Pneumatic Diagram, page 14,
and the label inside the color control module.
NOTE: The high pressure color change valves use a
spring-operated exhaust which does not require a second air line.
Connect Valve Fluid Lines
1. See FIG. 1. Connect fluid supply lines (FSL) to the
1/4 npt(f) inlet of each valve adapter. Supply solvent
to one valve (SV) at the top of the stack,
NOTICE
Verify that all unused fluid ports on the color change
valve stack are plugged before operation. An open
port will leak fluid.
2. Connect the hose (19) from the manifold stack fluid
outlet (F) to the flow meter inlet (M). F
NOTICE
A check valve is recommended on all dead head
valves to prevent color crossover if two valves are
open at the same time.
