Priming the System
The pump supplied with the system is NOT automatically self-priming and must not be run dry.
!WARNING! If the pump is allowed to run without fuel, pump damage will occur.
Priming Procedure
The pump head of the unit is shipped from the factory filled with oil to facilitate initial lubrication. This will not eliminate the
necessity to prime the complete system. The system is primed through the primary filter as well as the suction line(s) have
to be completely filled with fuel (no trapped air) prior to the initial system start-up.
The system is equipped with a vacuum switch on the input side of the pump. When the pump inlet vacuum reaches 12”
HG the system will shut down and activate the “HIGH VACUUM ALARM”. This indicates excessive debris, a flow
restriction, or too high suction height and therefore pressure drop in the suction line.
