4.4 Bleeding Product Lines
NOTE: To avoid severe damage to the dispenser, all air and air pockets must be bled from the
product trunk lines before attempting to dispense product.
Step 1 Make sure the power to the appropriate submersible pump is OFF.
Step 2 To bleed air from the trunk line, remove the pipe plug from the safety impact valve
on the dispenser that is farthest from the storage tank.
Step 3 Attach a flexible hose to the pipe plug opening in the safety impact valve and place
the other end into a test can. Energize the appropriate submersible pump and allow
the air to bleed out of the trunk line into the test can until product flows into the test
can. De-energize the submersible pump and replace the pipe plug.
Step 4 Repeat the procedure for each product and each trunk line.
4.5 Initial Delivery
After verifying the items in Section 4.1 through Section 4.4 have been completed, operation
of the dispenser can be checked.
Step 1 Turn on the circuit breaker(s) for the dispenser and, if applicable, the submersible
pump.
Step 2 If the dispenser is connected to a fuel control system, the dispenser must be
authorized.
Step 3 Remove the nozzle from the nozzle holder, and lift the on/off nozzle hook upward
to turn the dispenser on. Make sure the volume display resets to zero and the
message in the status display is “On.”
Step 4 Dispense fuel into a test can. Check all piping and hose connections to make sure
there are not any leaks.
Step 5 Turn the dispenser off by lowering the on/off nozzle hook to the down “off” position.
Return the nozzle to the holder.
Step 6 Repeat Steps 1 – 5 for each dispenser.
