OPTIONAL ADD-ONS
These add-on systems are for any liquid delivery supply units.

HD15 IN-LINE HEATER
For applications that require heating the HD15 In-Line Heater is an optional add-on for the Food Coating Supply Unit. The In-Line construction allow heating to be achieved only on-demand for optimal response and energy efficiency. For more information refer the HD-15 In-Line Heater Owner’s Manual
AIR CONTROL PANEL (ACP)
Provides and regulates the air supply to any nozzles utilizing atomizing and/or fan air. This unit also features a precision liquid regulator that allows for smooth and quick pressure adjustments. Easy access push-to-connect tube fitting ports are located on the top and bottom of the ACP. For more information refer the SCS Series Fluid Delivery System Owner’s Manual.

AUTO-REFILL
Auto-Refill is an optional module that helps refill the supply tank during opera-tion and recirculation. The auto refill system can be added to the Food Coating
System and requires a level sensor connection to attach to the con-trol panel. The level sensor displays the current tank level as a per-cent to full. The refill setpoint can be adjusted for user preference. TRANSFER PUMP
Easily transfer low to medium viscosity liquids out of drums and totes. Air driven sanitary design, piston pump, with air filter/ regulator.

FLOW METER
Designed for the 2150+ Spray Control Panel measures the flow of the nozzle

PRESSURE SENSOR
Designed for the 2150+ Spray Control Panel to provide liquid pressure monitoring and application adjustment.

SYSTEM START-UP

Fluid delivery is accomplished via a diaphragm pump mated to a back-pressure regulator allowing for excess fluid pressure to be recirculated back to the supply tank. A manual 2-way valve allows for the option of recirculation of fluid from nozzles back to supply tank. The main air is configured to supply the diaphragm pump with a single connection.

SETUP
Connect all process lines to the tanks, pumps and nozzles. Main air is configured to supply the diaphragm pump with a single connection. Before starting the system for the first time, be sure to follow all instructions on the drawings and in the “System Hook-Up and System Operation” section of this manual.

CAUTION: Always check all electrical, hydraulic, and pneumatic connections before powering on the system or turning on air/water supply.

To operate system, follow all startup procedures.

1. To fill the tank manually, open the tank lid and fill to desired level.
2. Turn on the air valve to the pump inlet to allow it to start pumping.
3. Set the desired liquid pressure using the manual pressure regulator. Excess pressure/flow will be released through the backpressure regulator and directly back to the tank.
4. Adjust the knob on the needle valve to adjust this rate of recirculation allowing for mild agitation of the contents of the tank. Never throttle the valve more than what the nozzles require for operation. This can be checked by running the nozzles and turning down the flow 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 circulating to increase pump speed.
5. If external circulation to the nozzles and back is desired, an orifice 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 recirculation.

FLUSH AND DRAIN TANK

1. If using auto-refill, complete the steps as needed in the Auto-Refill section of this manual and turn the refill control switch to “ON” (Auto-Refill section in “Optional Add-Ons” section of this manual).
2. To empty the tank, either direct the outlet fluid line to a drain or use the spray controller to flush the tank contents through the spray nozzles or header. Fill with any desired cleaning fluid which can be controlled with the approapriate controller.

WARNING: The air supplied to the machine must be clean, free of moisture and lubricating fluids; failure to do this will void all warranties.

AUTO-REFILL/LEVEL SENSOR
The automatic refill module allows the refill of the liquid pressure tank without having to shut down the spray process. Auto-refill (optional) comes with a level sensor, pneumatic ball valve, and optional drum pump. The auto refill module accepts a signal from the level sensor that when the liquid is low it triggers the refill tank.

Auto-Refill module consists of:

• Air-operated valve control panel
• Continuous liquid level sensor – low level indicator

AUTO-REFILL AND LEVEL SENSOR TO THE PUMP SET-UP:

1. Connect liquid lines from the pump to the refill port. Note, the rest position of the refill valve will have a circular indicator to the adjoined ports with no air actuating the valve.
2. The re-circulation port, in the rest position, is for recirculating the fluid from the source. This is useful for fluids that fall out of suspension, or if your pump is positive displacement it is required to use this fitting. If you do not wish to re-circulate, please plug this port.
3. Next, connect fluid line from the refill valve port to the fill port at the bottom of the tank. Supply air to the inlet on the control box (80 -100 PSI required to actuate the valve).

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. The auto-refill controller unit will supply air to the nomadic valve when the main tank level is low. In that case, the yellow light on the controller will illuminate indicating the automatic refill has been triggered and is currently filling.
4. The indicator light will shut off once the fluid reaches the high-limit setpoint via level sensor.

PROGRAMMING THE LEVEL SENSOR
The tank level sensor comes pre-programmed. However, the set points (Q1 – SP1 and Q1 – RP1) can be adjusted to configure the system specifically for the application.
The level sensor displays the tank level as a percent (%) full. However, all parameters are measured in millimeters (mm) from the bottom of the probe. The usable range of the level sensor is between 10 mm and 390 mm from the bottom of the probe.
There are two switching outputs that can be adjusted: Q1 and Q2. Output Q1 is used for the Auto-Refill feature and output Q2 is used for the Low Tank Level indicator.

| 50
Q2| RP2| Reset Point 2| Low Level – Indicator will turn on at or below

this value

| 10
Q2| OU2| Switching Function| Output Type – Normally Open/Closed| Qx-Hno

To access the above parameters from the main display (% full), press and hold the “Set” button. Use the up and down arrows to navigate to “Q1MENU” or “Q2MENU” and press the “Set” button. Use the up and down arrows to navigate to “SP1” or “RP1” (or “SP2” and “RP2”) and press the “Set” button. Use the up and down arrows and the “Set” button to change the numeric values assigned to the given parameter. Instructions for setting other parameters can be found on pages 32-35 of the provided component manual.

Assuming the tank has been initially filled and given the values in the above table, as the system is being used the level in the tank will decrease. Once the fluid reaches 250 mm from the bottom of the probe, 63% full (100% * (250-10)/390=64%), Auto-Refill will turn on. As the fluid level rises and reaches 390 mm from the bottom of the probe, 100% full, Auto-Refill will be turned off.

If Auto-Refill is switched off or the supply is interrupted, and the fluid level reaches 10 mm from the bottom of the probe, 0% full, the Low Tank Level indicator will turn on. This is intended as a warning that the system is not automatically refilling. The Low Tank Level indicator will turn off once the fluid level rises above 50 mm from the bottom of the probe, 10% full.

TRANSFER PUMP
Easily transfer low to medium viscosity liquids out of drums and totes. air driven, piston pump, with air regulator. SPECIFICATIONS (SUBJECT TO CHANGE BASED ON PROVIDED PUMP)

• Max. Air Inlet: 100 PSI (6.89 Bar)
• Max. Fluid Working Pressure: 250 PSI (17.24 Bar)
• Max. Output Flow: 10 GPM
• Air Consumption: 16 SCFM

SYSTEM START-UP

1. Check the regulator reads “0” psi.
2. Make sure all air and liquid supply fittings/lines are connected and secured fully before starting.
3. Start transfer pump process by turning the knob on the filter/regulator clockwise.
4. Slowly raise air pressure until the transfer pump begins cycling.
5. Use the regulator to control the pump speed and liquid pressure.
6. Since this is a 3:1 ratio piston pump, a pressure reading on the filter/regulator of 40 psi will output 120 psi.

PRESSURE RELIEF PROCEDURE

1. Using the filter/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 after 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 serious injury from splashing or moving parts.

WARNING: Never let the pump run dry of the fluid being pumped. A dry pump can accelerate and cause personal injury and/or damage to the pump.

FLUSHING
Flush at the lowest possible pressure and flush with a fluid that is compatible with the fluid being dispensed and the equipment wetted parts.

1. After Pressure Relief Procedures above, place suction tube in drum containing flushing fluid.
2. Set pump to lowest fluid pressure, and start pump.
3. Cycle pump until desired flushing is complete.
4. Completely relieve air pressure to pump before removing pump from drum.

CLEANING/MAINTENANCE

ATTENTION: Cleaning procedure is only a suggestion. Customer is ultimately responsible for a sanitation procedure that meets their requirements and standards.

CLEANING PROCEDURE

1. Turn the auto-refill switch on the main control panel to the “OFF” position (if applicable).
2. Close the 2-way ball valve on the pump’s incoming air inlet port. This stops the pump from operating.
3. Close the recirculation port 2-way ball valve.
4. Remove the hose/ tube connecting to the recirculation port inlet and use this line to remove majority of the fluid in the tank.
5. When ready, open ball valve for air inlet to the pump again to start draining the tank and fluid lines.
6. Once the tank is empty, then majority of the fluid is drained. Reconnect the open hose/tube to the recirculation port and open the recirculation ball valve.
7. At this point, the end user can fill the tank with their recommended cleaning solution. The cleaning solution can be recirculated.
8. Use the control panel to spray the nozzles until all process fluid remaining in the hoses, manifolds and nozzles is discharged.
9.  Clean the auto-refill system (as applicable).
   • Liquids for cleaning, rinsing, and sanitation can be added to the auto-refill supply tank and fluid delivery line.
   • Turn the auto-refill switch to the “ON” position to begin filling.
   • When complete, turn the auto-refill switch to the “OFF” position to stop pumping.
   • Repeat this process with appropriate fluids till the system is thoroughly flushed.
10. Clean the tank, delivery hose and nozzle assemblies.
    • Liquids for cleaning, rinsing, and sanitation can be added through the open top of the tank or fed through the auto-refill system.
    • Any inside surface on the pressure tank, sensors, or dip tubes can be manually cleaned, scrubbed, or wiped down.
    • Use the control panel to spray and move cleaning and sanitizing fluids through the hoses, manifolds and nozzles.
