Notes To Contractor/Installer
Some considerations may be needed prior to specifying the Red Jacket Submersible DEF pump and it’s
accessories/options. The system may be purchased with either an in-tank, fixed pressure relief or the adjustable
pressure relief which is installed in the sump.
The installation of the adjustable pressure relief requires plumbing to return the excess product to the tank. The
system will also work with DEF recirculation systems which require a separate return port. Please ensure there are
proper openings to route the product back into the tank and provision for other options such as vents, thermal
relief (adjustable pressure relief system only), remote fill, probes and the electrical cord grip.
The cord grip shall not be installed in the same opening as a product flow.
