Run the filter pump without the heater if this is a newly installed heater to removed any installation residue that may be present on the heater.
Use the knobs on the control panel to set your desired temperature for your heater. There are two knobs, one for the spa and the other for the heater. Rotate the knobs clockwise to increase the heat and rotate them counterclockwise to decrease the heat.
Set the middle control button between the two knobs on the control panel to either “Spa” or “Pool” to start the heater, warming the water to the temperature you selected for either the spa or pool mode.
Turn the middle control button on the control panel to “Off” when you are ready to turn off your Jandy heater.
