LA Spas manufactures many different series of spas including the Classic, Adventure, Premium North America and Premium Export among others.  LA Spas recommends filling the spa at the filter bucket area instead of in the foot-well to reduce the possibility of air pockets on newly filled hot tubs.  They also recommend cleaning the filters every other day for the first two weeks of operation.

To clean the filter, be sure the spa is turned off. The filter bags used on some LA spas (Aqua Klean) are supposed to be washed in a washing machine using 1/4 cup of bleach. Do not put your cartridge filters in there, that is only for these filter bags if equipped. (Also do not use in a dryer).

If you run into an FLO problem, be sure the filters are clean. This may also be a real flow problem related to an air lock or obstruction in the plumbing line, or it may be an issue with older-style pressure switches or sensors.
