Preparation
The A1A 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. Special ventilation is not required.
The pump can be mounted on a level flat surface, or the pump can be wall-mounted using the provided bracket. Blue-White also offers a sturdy polyethylene (PE) Wall Shelf to mount the pump.
Piping and Physical Installation
The A1A Pump must be level to ensure pumping accuracy.
If mounting the pump to the wall using the provided bracket, follow these instructions:
- 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.
- Ensure the bracket is mounted level and screws are secure and will support the weight of the pump and any connected tubing. Use screw type appropriate for your mounting material.
Lower the pump so the tab on the wall bracket is inserted into the slot on the back of the pump. The pump will snap into place and is now secure. To release and remove the pump, reach to the back of the pump and pull the tab forward while lifting the pump.
If mounting the pump to the floor or shelf, follow these instructions:
- Place the bracket on a flat and level surface. Secure bracket to base using screws.
- Place the pump on mounted bracket.
Connecting Suction and Discharge Tubing/Piping
A1A Pump tube elements have 1/4’” x 3/8” tubing connections (designated by “T” in the tubing part number)
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 strainer and weight is recommended.
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.
Typical Installation Diagram
Note: We highly recommend installing a injector/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 continually feeding into the pump head.

Wiring
Power Wiring
The A1A is powered by 100 to 240VAC, 50/60Hz power. Use the provided 4’ power cord, and attach the cord at the bottom of the pump.
A removable power cord is only included if the pump is ordered with either a “4” 115V 50/60Hz-NEMA 5/15 plug(US), or a “6” 220V 50/60Hz-CEE 7/V11plug. See accessories for alternate power cord options (ordered separately.) If using a power cord not provided by Blue-White, the cord must be IEC C13 rated at 250 volts and fit into a standard IEC320-C14 receptacle.
Control Wiring
The A1A pump has an optional I/O connection via an M8 4-pin connector on the front of the pump.
Connection to the M8 must be accomplished with shielded and insulated cables with a 250VAC voltage rating. (M8 cable is not included with the pump. See accessories or purchase separately.)
Signal connection includes:
- Remote Start/Stop Input (Dry Contact Closure)
- Alarm Output (TFD-leak detection) – 48 VDC @ 80 mA relay
See the below Wiring Chart for information and specifications in connecting to your electrical and control system.
Refer to the instructions in the manual for detailed information.
