The Balboa VL404 Topside is usually installed on Spas with a Balboa VS Control System. This system allows the user to select their desired filtration cycles.
The filtration cycle is meant to circulate and maintain the cleanliness of the spa water. By circulating, not only is the heated water being dispersed throughout the tub, but it has a chance to pass through our elaborate filtration process.
Your spa has multiple filtration cycles: F2, F4, F6, and FC.
F2 – Filtration cycle will run for 2 hours, every 12 hours.
F4 - Filtration cycle will run for 4 hours, every 12 hours.
F6 - Filtration cycle will run for 6 hours, every 12 hours.
FC – Filtration cycle will run continuously.
To switch between the different filtration cycles available, follow instructions below:
1. Press the Temperature button
2. Then, press the Jets button.
3. Keep pressing the same sequence of buttons until the desired filtration cycle appears on the display (F2, F4, F6, FC)
