1Switch the spa off at the isolating switch or main breaker (Bullfrog: turn off main power to the spa).
2A Series: remove the JetPak in front of the Simplicity filter housing, the first JetPak to the right of the main control. M Series and Swim Series: see your owner's manual for where the filter is.
3Reach into the jet pod, grasp the handle of the Simplicity filter holder, push it toward the inside of the spa and lift it out.
4Open the holder, lift the old filter out by its loop and fit a new one with the glue lines showing: slide one end under the retention slots and press the looped end down.
5Snap the holder back into the housing with a back-and-down motion, refit the JetPak and turn the power back on.

After fitting the new cartridge

The A Series status light gives a slow fading flash when a filter needs replacing; mark the reminder as done on the control screen after fitting the new filter and the light returns to solid white (Bullfrog A Series manual).
