Embedded Functions

During a technical service call, you may be asked to perform tasks

which require you to press combinations of keys. These tasks are defined

below.

10.1 Software Confirmation

To check the version of software installed in the Econo Pump, simul-

taneously hold down the direction key (in the upper left corner) and the

“down” arrow key on the front panel of the Econo Pump. The four digit

display should display “v2.01” or higher.

10.2 Warm Reboot

You may be asked to perform a warm reboot if the Econo Pump soft-

ware is not functioning properly. To initiate a warm reboot, press the

Tubing Calibration and Down Arrow keys simultaneously and hold for 3

seconds.

10.3 Cold Reboot

A cold reboot may be necessary if the warm reboot was unsuccessful.

Turn off the pump and hold the Tubing Calibration and Down Arrow keys

while turning the pump back on. Hold the two keys until the display

stabilizes.
