NOTE: It is a good idea to keep a spare filter to use in the spa while the dirty filter is being deep cleaned.
This way, you can rotate the filters and both will last longer.
3. Soak the filter for a minimum of 24 hours.
4. Spray the filter with a water hose. Spray each pleat carefully.
5. Reinstall the filter. Do not over-tighten.
4.6 Ozonator
The ozone generator releases ozone into the spa water. You will still need to test for chlorine or bromine and
occasionally replenish it to return the sanitizer level to the baseline.
For spas without a circulation pump, pump 1 will run at low speed and the ozonator will run during
filtration.
The spa’s control system is factory -programmed with one filter cycle that will run in the evening when
energy rates are often lower. The time and duration of the filter cycle can be set according to your needs. In
addition, a second filter cycle can be enabled. Filtration time may need to be increased with heavy bather
load.
See instructions for setting filtration cycles on page 17.
