C. Priming the Pump
1. To prime the pump, press the MANUAL button – the bar at the bottom of the display will move from right
to left from OFF to AUTO to ON. When it reaches ON, the pump will run until the MANUAL button is
pressed again. Use this position to prime the pump as well as to calibrate the pump. To stop priming press
the MANUAL button – the bar at the bottom of the display will move from left to right from ON to AUTO
to OFF.
Note: The unit may continue to run in the AUTO position and the MANUAL button must be pressed
until the bar at the bottom of the display is over the OFF position to stop the unit fully.
D. Setting into Programmed Position
1. Press the MANUAL button until the bar in the bottom of the display moves from the OFF to the AUTO
position. If the unit is not in the AUTO position, the program will not be executed.
Specifications: When the unit is powered the first time, the rechargeable display back up battery begins charging.
When fully charged it provides approximately 200 hours of reserve time before the display and program may be lost.
If the unit loses power, it will not lose the program for 200 hours, but it will not run the pump from the rechargeable
display back up battery and will not dispense chemical. If the unit becomes unplugged from the wall for a short
amount of time, plugging the unit back in will not affect the programming done to the unit.
