Preparation
The CD3 (Legacy) 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. We recommend using the provided mounting brackets for secure installation. Blue-White also offers a sturdy polyethylene (PE) Wall Shelf to mount the pump.
Piping and Physical Installation
The CD3 (Legacy) Pump must be level to ensure pumping accuracy.
If mounting the pump using the mounting bracket, follow these instructions:
- Use the diagram and drawing on the manual (or below) to mount the pump and bracket to a secure 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 to the pump first using the provided hardware.
- Ensure location provides enough space for inlet and outlet connections to the pump, and ensure enough space for rear wiring.
- Place the pump and secure to the base surface using the appropriate hardware for the base surface.
If mounting the pump to a shelf, be certain the shelf will be able to support the weight of the pump.
Connecting Suction and Discharge Tubing/Piping
CD3 (Legacy) Pump has many options for connection to 1/2” pipe or hose/tube.
“M” 1/2” MNPT connection.
“B” 1/2” Hose Barb connection.
Any injection valve, suction strainer, or tubing must be purchased separately.
Connecting Suction and Discharge Tubing
Before connecting the tubing or piping to the pump, be sure the pump powered 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.
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.
