Before You Begin
1. Ensure that the submersible turbine pump (STP) is properly grounded as per the manufacturer’s instructions.
2. A shutoff valve installed between the DPLLD transducer and the product pipeline is recommended. Although
not required for the DPLLD equipment to work, the valve will aid in troubleshooting the system and in reducing
any product spillage when performing service work in the sump.
3. The SwiftCheck valve requires a 3” hex socket (or wrench) for tightening it in the pump’s leak detector port.
The non-vented SwiftCheck valve requires a 1-1/2” hex socket (or wrench) for tightening it in the pump’s leak
detector port.
4. If you are installing DPLLD into a Red Jacket Standard STP you will need a new Functional Element.
Warning Tags
Turn off, tag (using the warning tags provided), and lockout power to the console and
submersible pumps while installing the DPLLD equipment. This will prevent either a
dispense attempt or the DPLLD equipment from automatically starting up the pump.
Warning tags [Figure
1] are provided with the DPLLD equipment. For your safety and the safety of others who may
service dispensers, submersible pumps, or DPLLD equipment, you must attach a tag to each of the following
devices where it can clearly be seen by a service person performing work on the system:
• Console
• Submersible pump
• Dispenser filter
