Installation

What’s in the Box 

The A-100NFP Pump is shipped with the following contents: 

• A-100NFP Peristaltic Metering Pump 
• Two tube assemblies (1 installed, 1 spare) 
• Discharge injection fitting with check valve 
• Suction tube – clear PVC – 5′ length (3/8″ OD, 1/4″ ID) 
• Suction strainer 
• Suction ceramic weight 
• Discharge tube – opaque polyethylene – 5′ length (3/8″ OD, 1/4″ ID) 
• Mounting hardware kit 
• Shroud (weatherproof cover) 
• Power Cord (if ordered) 

Preparation 

The A-100NFP Pump is designed to withstand outdoor conditions, although it is recommended to locate the pump in a protected enclosure for maximum pump life. A cool, dry location where the unit can be easily monitored is recommended.  

The pump can be mounted on a level, flat surface, or the pump can be wall-mounted.  Blue-White also offers a sturdy polyethylene (PE) Wall Shelf to mount the pump.  

Piping and Physical Installation 

The A-100NFP Pump must be level to ensure pumping accuracy. 

If mounting the pump to the wall using the provided wall bracket, follow these instructions: 

1. Use the diagram and drawing on the manual (or below) to mount the bracket to a secure wall location.  We recommend mounting the pump at a height where the display and indicator lights are easily visible, and where it can be easily serviced. 
2. Mount the pump close to the injection point. 
3. Mount the pump to the side or lower than the chemical tank.  
4. Mounting the pump lower than the chemical container will gravity-feed the chemical into the pump. This “flooded suction” installation will reduce output error due to increased suction lift. You must install a shut-off valve, pinch clamp, or other means to halt the gravity feed to the pump during servicing.

Connecting Suction and Discharge Tubing/Piping 

A-100NFP Pump tube elements have 1/4’” x 3/8” tubing connections (designated by “T” in the pump or tubing part number.)  

The pump will come with suction and discharge tubing, suction strainer, and discharge injection valve. 

Before connecting the tubing to the pump, be sure the pump is OFF. Wear protective clothing and eye protection when connecting tubing to chemicals or chemical lines. 

Connect the suction tubing to the pump, and place and secure the other end of suction tubing in the chemical tank/source. Using the provided foot valve/strainer and weight is recommended. 

Strainer. – Trim the inlet end of the suction tubing so that the strainer will rest approximately two inches from the bottom of the solution tank. This will prevent sediment from clogging the strainer. Slip the ceramic weight over the end of the suction tube. Press the strainer into the end of the tube. Secure the ceramic weight to the strainer. Drop the strainer into the solution tank.

Connect the discharge tubing to the pump and then connect the other end to the discharge point. If using the provided injection valve, be sure to mount it in an upward position to prevent air bubbles from collecting.  

Note: We highly recommend installing a check valve on the discharge side of the pump. The check valve can be in the form of an injection check valve, in-line check valve, quick disconnect check valve, or similar. When there is a tube leak, the check valve will prevent chemicals from the discharge line from continually feeding into the pump head.

Wiring 

Power Wiring 

The A-100NFP can be powered by the following power sources: 

• 115VAC/60Hz, 1ph (.51 amp max)  
• 230VAC/60Hz, 1ph (.56 amp max)  
• 220VAC/50Hz, 1ph (.66 amp max)  
• 240VAC/50Hz, 1ph (.58 amp max) 

Use the provided 6’ power cord, or an appropriately protected IEC C13 cord rated at 250 volts. 

• Be sure to connect the pump to the proper supply voltage. Using the incorrect voltage will damage the pump and may result in injury. The voltage requirement is printed on the pump serial label.   
• The pump is supplied with a ground wire conductor and a grounding-type attachment plug (power cord). To reduce the risk of electric shock, be sure that the power cord is connected only to a properly grounded, grounding-type receptacle. 
• Note: When in doubt regarding your electrical installation, contact a licensed electrician. 

Optional Signal Wiring 

The pump includes three optional external signal connections:  

 FVS – FLOW VERIFICATION SENSOR INPUT Accepts a pulse signal from an optional Blue-White sensor confirming that fluid is passing through the pump. Triggers the AL alarm output if fluid is not detected. 

AL – ALARM OPEN COLLECTOR OUTPUT The output (purple wire) sinks to DC ground when an alarm condition exists. 6-30Vdc collector voltage. 50mAdc maximum sinking current. 

MA – MOTOR ACTIVE OPEN COLLECTOR OUTPUT The output (brown wire) sinks to DC ground when the motor is de-energized. 6-30Vdc collector voltage. 50mAdc maximum sinking current.  

All signal wires must be connected to the circuit board, located inside the pump enclosure, using connector plug wiring assemblies. A liquid-tight connector must be installed in the pump enclosure wall and the signal wires passed through the liquid-tight connector and secured.   

1. Remove the rear enclosure panel.  
2. Remove knock-out using a screwdriver.  
3. Trim edge with a knife and remove sharp edges.  
4. Install the provided liquid-tight connector.  
5. Connect the connector plug to the circuit board.

See the below Wiring Chart for information and specifications in connecting to your electrical and control system.

SYSTEM DESCRIPTION	WIRE COLOR CODE
FVS – FLOW VERIFICATION SENSOR INPUT Accepts a pulse signal from an optional Blue-White sensor confirming that fluid is passing through the pump. Triggers and alarm output if fluid is not detected.	RED (+ 20VDC) BLACK (-) YELLOW (signal)
TFD – TUBE FAILURE DETECTION SYSTEM INPUT Monitors a pair of sensors in the pump head. Triggers an alarm output if fluid with a conductivity of greater than 500 micro-Seimens is detected. Typical chemicals include chlorine, acid, and caustic. The system will not detect water or silicone lubricating oil.	GRAY & GRAY
