Jet MAXI D125 Operation & Maintenance Manual page 22

If the pump has a plastic bleed screw like the one shown below, do not use excessive force or
attempt to use any tools to turn it as this may damage the pump casing.
Forcing Pumps to Run
Turn on the power supply to the digital controller and wait for the system pressure to appear on
the display. Then, enter the code 2601 and go to the first setting in the menu, cold fill. While at
this point in the menu, holding down the (MUTE) button will force pump 1 to run, and holding
down the (SET) button will force pump 2 to run.
If the controller is older than V6.1 then there is no way to force pump 2 to run via the controller.
To force the second pump to run, the unit must be isolated and the live wires in terminals 13 and
14 must be swapped over. The second pump then becomes "pump 1" and can be forced to run
via the controller.
To bleed the pumps, the pumps must be started. Then while the pump is running, the bleed screw
must be opened until all the air has been removed and only water is being discharged. The bleed
screw can then be closed.
Failure to bleed the pumps may result in damage to the equipment, system and property.
After bleeding the pumps, close the drain valve and remove the hose from the hose tail.
