refer to Trouble Shooting section.
11b. (See Figure 6 on page 15) - If this function is not needed, leave it in the off
position. To set the Auto Shut Down Counter:
a. Input the number of cycles desired to disable the PF machine onto the Auto Shut
Down Counter by pushing in on the gray buttons to set the Countdown Value. The
bottom row of green numbers identifies the set point. The top row of numbers
identifies the number of cycles left to count down and will initially be colored red
before the Countdown Value is set. Each button corresponds to a specific digit.
For example, in order to set the Auto Shut Down Counter to a value of 136 as seen
in the images below, press Button 1 (6) times, Button 2 (3) times and Button 3
(1) time. See table on page 29 for approximate cycles required per gallon or liter.
b. Press the gray “RST” button on the bottom left of the display to set the countdown
value. The top row of numbers will now become green. Turn the Pump Switch
(See Figure 6 on page 15) to Normal. The top row of numbers will count down
by 1 after each cycle of the Pump Line is completed.
c. After the Pump Line has completed the set number of cycles, the Countdown Value
will read “0” and change color to red, the Pump Line will stop in the Retract
position, and the Pump Switch/Indicator Light will no longer illuminate.
d. To make the machine operational again, reset the Countdown Value by pressing
the “RST” button with the next desired Countdown Value or by shutting off the
Auto Shut Down Counter.
