ADJUSTING FILTRATION
PURGE CYCLES
In order to maintain sanitary conditions, as well as protect against freezing, all pumps will purge
water from their respective plumbing by running briefly at the beginning of each filter cycle. It is
best that all jets be left in their open position and water diverters in their centered positions when
done using the spa so all jets get water flow during purge cycles.
If the Filter Cycle 1 duration is set for 24 hours, enabling Filter Cycle 2 will initiate a purge when
Filter Cycle 2 is programmed to begin.
THE MEANING OF FILTER CYCLES
1. The heating pump always runs during the filter cycle*
2. In Rest Mode, heating only occurs during the filter cycle
3. Purges happen at the start of each filter cycle
* For example, if your spa is set up for 24/hour circulation except for shutting off when the
water temperature is 3˚F/1.3˚C above the set temperature, that shutoff does not occur during
filter cycles.
