Priming Mode – M019
Each time the spa is powered up, it will enter Priming Mode. The purpose of Priming Mode is to allow the user to run each pump and manually
verify that the pumps are primed (air is purged) and water is fl owing. This typically requires observing the output of each pump separately, and is
generally not possible in normal operation. Priming Mode lasts 4 minutes, but you can exit it earlier by pressing any Temp button. The heater is not
allowed to run during Priming Mode.
NOTE: If your spa has a Circ Pump, it will turn on with Jets 1 in Priming Mode. The Circ Pump will run by itself when Priming Mode is exited.
