Frequently Asked Questions
UNIT OPERATION
-
It depends on how many gallons of DEF is sold daily. The tank size is 525 gallons, so if your selling on average 30 gallons of DEF per day, you have about 17 days of supply in your tank. We would recommend refilling your tank bi-weekly. Based on our experience, we believe it’s best to work with your DEF supplier and plan to schedule either twice per week, once per week, or every other week.
-
This unit is rated to operate above 12 F which is where DEF freezes. There are additional Add-ons to support -40 operating temperatures
-
When the dispenser doesn’t respond to a card swipe or tab, does not dispenser fluid or if the flow rate seems very slow.
-
The HUDD dispenser itself is not rated for installation within pump islands—only the register is UL certified. Local authorities may allow exceptions, so we recommend checking with your fire marshal before installing.
