How do you replace the filter on a Freeflow spa?

The spa uses a screw in filter cartridge that is easily removed.  

1. Turn off the power to the spa, (by turning OFF the subpanel breaker). 
2. Push down slightly and turn the weir and the basket until it reaches the release tabs then pull the basket and weir out. 
3. Unscrew the filter counterclockwise and bring it out of the spa (requires many turns). 

If you need to replace your filter, you can purchase a new one here. All models accept for the 2-person Mini take the 50 sq ft filter. The Mini takes the 25 sq ft filter.
