4.4 AIR FILTER/REGULATOR
• The system is provided with an air lter/regulator and lock out valve assembly. The unit is provided detached for
you to mount directly to the unit or your preferred locaon.
• Connect a 40-100 psi max air supply line to the input ng of the lockout valve. Make sure that the lockout valve
is in the closed posion prior to connecng the unit to the air supply.
4.5 SETUP
SUPPLYING AIR TO THE SYSTEM
1. Turn the red valve on the air inlet valve/regulator/lter clockwise to the on posion. Turn regulator that is on top
of the air lter to an air pressure between 40-100 psi (2.8-6.9 bar). Air pressures higher than this will shorten the
life of the pump. Air pressure should be 20 psi higher than the pressure intended to spray at.
2. Adjust the regulated pressures (regulators on front panel).
 If applicable, depending on your spray system you may have anywhere from liquid pressure regulaon only to
liquid pressure; pump air (preset); atomizing air (drop size); fan air (spray angle/paern).
3. Adjust the liquid pressure regulator: The regulator can be adjusted by rst pulling up on the knob and then turn-
ing clockwise to increase and counter-clockwise to decrease the pressure. When the proper liquid pressure is
reached, press down on the knob to lock it in place.
Note: The pressure is non-relieving and therefore may not relieve the pressure unl the spray nozzle is spraying
again.
4. Adjusng the atomizing and fan air: Each air control line is equipped with a manual air pressure regulator. The
regulators can be adjusted by rst pulling up on the knob to unlock the regulator and then turning clockwise to
increase and counter-clockwise to decrease the pressure.
5. Once the proper air pressure is reached, press down on the knob on the regulator to lock it in place.
Note: Your system is equipped with cylinder air for air actuated spray nozzles. Cylinder air pressure is equal to the
inlet air pressure to the system. It is not regulated; therefore, you must provide a minimum of 45 psi (3.1 bar) to
the system. It must be above 45 psi (3.1 bar) to actuate air actuated nozzles like Spraying Systems Co.® 1/4JAU
series.
6. For systems that control pneumacally actuated nozzles connect 1/4” (6 mm) O.D. tubing from the cylinder air
out port of the bulkhead to the spray nozzle cylinder air ports.
 Tubing may be supplied with oponal spray nozzle hook up kit (metric nozzle hook up kits are not available)
7. Connect 1/2” (12 mm) O.D. poly tubing from the atomizaon air and fan air push-in ngs (if needed) on the side
of the enclosure to their corresponding ngs on the spray nozzles.

IF YOU HAVE PRESSURE SENSOR:
6) Hookup the 1/4” NPTF outlet to the 1/2” NPTF liquid outlet on the pump. Than aach the M12 pressure
port cable to the corresponding M12 solenoid cable for cylinder air port on the ACP.
See your specied Control Panel Manual for all sensor and cable specicaons.
5.4 PRIMING THE PUMP
When the pump is not lled with liquid (this would be the case for the rst use of the system) the pump and system
will need to be primed.
To prime the pump:
1. Turn on the main air to the system (red valve on side). Ensure you have adequate liquid I the supply reservoir.
2. Turn the liquid regulator, on the front panel, at least 1 or 2 turns clockwise.
3. Disconnect the liquid out tubing from the nozzle to allow max. ow for priming.
4. Allow the pump to cycle quickly unl the pump is fully primed. (1-4 Hz.), this can take up to 1 minute depending
on priming height and uid viscosity. Ensure all the air is pushed out through the tubing so that all the air bubbles
are minimized.
 It may be necessary to reduce the pump air pressure to the system slightly to prime pump.
 The pump is self-priming, so it can be above the level of the liquid (max. 5 ./1.5 m) during the priming
process but keep this to a minimum for priming if possible.
5.5 RECIRCULATION
Re-circulang the uid from the system to the supply tank keeps the uid in a state of moon, keeps uid pressure
constant, and eliminates pulsing from the pump. This is very useful when spraying uids that need agitaon to keep
the parculates in suspension.
Each of these recirculaon modes are described below:
• The rst method is to re-circulate the uid out to the spray nozzle and back into the system through the second
liquid port and back into a needle valve. (Ex. Nozzles of headers that have this feature include AA250AUH, VAU
and VMAU, 98250 product lines)
Standard Recirculaon Hook-Up Pump Recirculaon Inlet

13
• The second method is to ulize a “T” splier on the liquid outlet line with one leg ed into the uid return line
and back into the needle valve. The “T” splier can be located anywhere from the pump outlet to the back of the
nozzle itself.
• Both inlet/outlet are 3/8” ODT push-to-connect ngs
SETTING THE RECIRCULATION FLOW
Counter-clockwise will open the valve and increase recirculaon ow. Clockwise will decrease the recirculaon ow.
To adjust the amount of uid that is circulang turn the knob counterclockwise unl you have reached the desired
amount of recirculaon/back pressure.
ATTENTION: If valve is open too much the pump will not keep up with the ow and your pressure
can drop.

SECTION 6
PUMPLESS VERSION
6.1 OVERVIEW
The Pumpless Version is the liquid regulator only. It is designed for applicaons where uid delivery ulizes a
pressurized source typically supplied by the customer. This small assembly ships loose to be mounted directly to the
uid supply. The pumpless system controls the ow of liquid using an internal, air piloted liquid pressure regulator via
the Air Control Panel (ACP). The pumpless version is available in food contact and non-food contact conguraons.
Pumpless version requires the liquid source to be pressurized from 10 psi min above the maximum applicaon pres-
sure. The maximum required applicaon or discharge pressure must not exceed 100 psi. This version has the opon to
re-circulate liquid from the system back to the supply tank. Recirculaon does require the customer to use a pump
and reservoir.

SECTION 8
COATING SUPPLY UNIT—THREADED
8.1 OVERVIEW
The Coang Supply Unit is designed for applicaons that require a larger tank size (15 gal/56.8 L) and that may benet
from a higher ow rate system with more automated capabilies with the inclusion of auto-rell. The Coang Supply
Unit uid delivery consists of a diaphragm pump mated to a back-pressure regulator that allows for excess uid pres-
sure to be re-circulated back to the supply tank. The outlet and recirculaon ports of the system have manual 2-way
ball valves that allow the user to enable/disable output ow to the nozzles or manifold for recirculaon.
Note: The Coang Supply Unit requires the use of an Air Control Panel (ACP) and paired with control panels dedicated
to the nozzle on/o control.
8.2 SPECIFICATIONS
• Air Pressure—20/100 psi
• Air Input—1/2” NPT (F), 10 SCFM (min.) - 100 SCFM (max.)
• Construcon—Polyethylene (tank only)
• Dimensions: 42” x 34” x 25”
• Supple Tank Volume—15 gal.
ENVIRONMENTAL
• Operang Temperature Range—32° to 120°F (0° to 42.8°C)
• Humidity Range—5 to 95% (Non-condensing)
LEVEL SENSOR (OPTIONAL)
• Time Domain Reectometry (TDR) - 24 VDC
8.3 SETUP
Connect all process lines to the tanks, pumps and nozzles. See electrical control panel connecons for your specic
cables and wiring for your system. Main air is congured to supply the diaphragm pump with a single connecon.
Before starng the system for the rst me, be sure to follow all instrucons on the drawings and in the “System Hook
-Up and System Operaon” secon of this manual.
CAUTION: Always check all electrical, hydraulic, and pneumac connecons before powering on the
system or turning on air and water supply.
To operate system, follow all startup procedures above.
1. To ll the tank manually, open the tank lid and ll to desired level.
2. Turn on the air valve to the pump inlet to allow it to start pumping shown in
Figure 2.
3. Set the desired liquid pressure using the manual pressure regulator shown in
Figure 1. Excess pressure/ow will be released through the backpressure reg-
ulator and directly back to the tank.
4. Adjust the knob on the needle valve to adjust this rate of recirculaon allow-
ing for mild agitaon of the contents of the tank. Never throle the valve
more than what the nozzles require for operaon. This can be checked by
running the nozzles and turning down the ow of air to the pump. If you start
to see large drops in the air pressure control gauge, the pump speed is too
low to keep up. Adjust the needle valve while spraying and circulang to in-
crease pump speed.

17
5. If external circulaon to the nozzles and back is desired, an orice plate is provided at the return.
6. Make sure 2-way ball valve on liquid outlet is open and if desired, 2-way ball valve on liquid inlet is open for re-
circulaon.
FLUSH AND DRAIN TANK
1. If using auto-rell, complete the steps as needed in the Auto-Rell secon of this manual and turn the rell
control switch to “ON” (Auto-Rell secon in “Oponal Add-Ons” secon of this manual).
2. To empty the tank, either direct the outlet uid line to a drain or use the spray controller to ush the tank
contents through the spray nozzles or header. Fill with any desired cleaning uid which can be controlled with
the approapriate controller.
WARNING: The air supplied to the machine must be clean, free of moisture and lubricang uids;
failure to do this will void all warranes.
8.4 AUTO-REFILL/LEVEL SENSOR
The automac rell module allows the rell of the liquid pressure tank without having to shut down the spray pro-
cess. Auto-rell (oponal) comes with a level sensor, pneumac ball valve, and oponal drum pump. The auto rell
module accepts a signal from the level sensor that when the liquid is low it triggers the rell tank.
Auto-Rell module consists of:
• Air operated valve control panel
• Connuous liquid level sensor – low level indicator
HOOK-UP AUTO-REFILL AND LEVEL SENSOR TO THE PUMP:
1. Connect liquid lines from the pressurized supply to the rell port. Note, the rest posion of the rell valve will
have a circular indicator to the adjoined ports with no air actuang the valve.
2. The re-circulaon port, in the rest posion, is for recirculang the uid from the source. This is useful for uids
that fall out of suspension, or if your pump is posive displacement it is required to use this ng. If you do not
wish to re-circulate, please plug this port.

3. Next, connect uid line from the rell valve port to the ll port at the boom of the tank and connect the air
supply to the auto-rell panel.
AUTO-REFILL CONTROL PANEL SET-UP
1. Connect power to the controller.
2. Plug the level sensor cable into the sensor mounted to the main tank
unit.
3. An NPT thread push tube ng needs to be added to the air inlet port on
the boom of the controller provided by the customer. Air must be
supplied to the air inlet port.
4. The auto-rell controller unit will supply air to the pneumac valve
when the main tank level is low. In that case, the yellow light on the
controller will illuminate indicang the automac rell has been
triggered and is currently lling.
5. Supply air to the inlet on the control box (0-100 PSI max.)
PROGRAMMING THE LEVEL SENSOR
The auto rell system can be added to the Coang Supply Units and requires a level sensor connecon to aach to the
control panel. The level sensor displays the current tank level as a percent to full. The rell setpoint can be adjusted for
user preference.
The tank level sensor comes pre-programmed. However, the set points (Q1 – SP1 and Q1 – RP1) can be adjusted to
congure the system specically for the applicaon.
The level sensor displays the tank level as a percent (%) full. However, all parameters are measured in millimeters (mm)
from the boom of the probe. The usable range of the level sensor is between 10 mm and 410 mm from the boom of
the probe, a 400 mm range.
There are two switching outputs that can be adjusted: Q1 and Q2. Output Q1 is used for the Auto-Rell feature and
output Q2 is used for the Low Tank Level indicator.
To access the above parameters from the main display (% full), press and hold the “Set” buon. Use the up and down
arrows to navigate to “Q1MENU” or “Q2MENU” and press the “Set” buon. Use the up and down arrows to navigate
to “SP1” or “RP1” (or “SP2” and “RP2”) and press the “Set” buon.
Use the up and down arrows and the “Set” buon to change the numeric values assigned to the given parameter.
Instrucons for seng other parameters can be found on pages 32-35 of the provided component manual.

in the tank will decrease. Once the uid reaches 250 mm from the boom of the probe, 63% full (100% * (250-
10)/380=63%), Auto-Rell will turn on. As the uid level rises and reaches 390 mm from the boom of the probe,
100% full, Auto-Rell will be turned o.
If Auto-Rell is switched o or the supply is interrupted, and the uid level reaches 10 mm from the boom of the
probe, 0% full, the Low Tank Level indicator will turn on. This is intended as a warning that the system is not
automacally relling. The Low Tank Level indicator will turn o once the uid level rises above 50 mm from the
boom of the probe, 10% full.

2.78 GPM (10.52 lpm)
Air consumpon: 8 SCFM
Max. uid temp: 190°F (88°C)
SYSTEM START-UP
1. Check the regulator reads “0” psi.
2. Make sure all air and liquid supply ngs/lines are connected and
secured fully before starng.
3. Start transfer pump process by turning the knob on the lter/
regulator clockwise.
4. Slowly raise air pressure unl the transfer pump begins cycling.
5. Use the regulator to control the pump speed and liquid pressure.
6. Since this is a 2:1 rao piston pump, a pressure reading on the lter/regulator of 40 psi will output 80 psi.
PRESSURE RELIEF PROCEDURE
1. Using the lter/regulator, turn knob counterclockwise to relieve pressure.
2. Once gauge reads “0” psi, the liquid supply can be removed.
3. If nozzle/hose is clogged/pressure has not been fully relieved aer following the steps above, very slowly loosen
the hose end coupling to relieve pressure gradually, then loosen completely. Clear hose or nozzle blockage.
CAUTION: Trapped air can cause the pump to cycle unexpectedly, which could result in seri-
ous injury from splashing or moving parts.
WARNING: Never let the pump run dry of the uid being pumped. A dry pump can acceler-
ate and cause personal injury and/or damage to the pump.
FLUSHING
Flush at the lowest possible pressure and ush with a uid that is compable with the uid being dispensed
and the equipment weed parts.

TROUBLESHOOTING
Some faults set the system into standby mode. In this mode, no further triggers are accepted unl the reason for
the fault has been corrected. Once the fault has been corrected, complete a power cycle of the spray control panel.
For some faults the SCS Series spray control panels will recover without intervenon, but will sll indicate the fault
on the fault screen. You can access the fault screen by touching the nocaon box, see reason for the fault if it has
been xed and easily reset any fault message by touching the “Reset” buon. All faults have a tolerance me which
is the me the error needs to be acve for the fault to occur. See your specic control panel manual for more infor-
maon and contact your Spray Specialist by calling 1-800-95-SPRAY (1-800-957-7729).
 Spray control panel will not operate spray nozzle
— Ensure that there is proper uid pressure supplied to the nozzle.
— Ensure that system is recognizing your trigger input. This is a common problem. If remote trigger/sensor is being
used and buon on the setup screen is set to “local”, the system cannot be triggered, the system trigger needs
to be set to something other than “local”. The inverse is also true, if the system is being triggered from the HMI
screen, the trigger opon must be set to “local”. Make sure your sensor is NPN design if you are using your own
sensor.
) Ensure that the trigger mode is set to Local, DI2 or DI2+ DI4.
) Navigate to the diagnosc screen.
) Acvate the main trigger source (object sensor or equivalent): DI2 on diagnosc screen should go from O to
On when the trigger device is acvated
- If this does not occur, then ensure that the trigger device is properly wired
- If problem sll occurs, then consult your controller panel owner’s manual for the trigger device
) If trigger mode is DI2+ DI4, acvate the auxiliary trigger: The diagnosc screen on run mode should go from O
to On when trigger device is acvated.
- If this does not occur, then ensure that the trigger device is properly wired.
- If problem sll occurs, then consult the owner’s manual for the trigger device.
 For electrically actuated spray nozzles:
1) Check that the nozzle cable is properly installed on both ends with no damage to the cable.
) Set duty cycle to 100% from main screen and aempt to trigger again.
- If the nozzle acvates you may have selected a duty cycle too low or max frequency too high for the nozzle
you are using.
- If the problem persists have a qualied electrical technician, ensure that there is 24 VDC on the nozzle cable
when the system is triggered.
 For pneumacally actuated spray nozzles.
— Ensure that there is a minimum of 45 psi (3.1 bar) of air pressure on the main air input to the system and that
the main air valve is in the “on” posion.
— Check air supply.
) Ensure that the valve cable is connected to the main output on the spray control panel.
) Remove cylinder air tube from the outside port of the system.
) Trigger the system to see if air comes out of the port.
) If air comes out they there is an issue with the cylinder on your nozzle. Contact your spray specialist for infor-
maon on repairing or replacing your nozzle.
