Pure Cure™ Water Sanitizer
The Pure Cure™ water sanitizer is an optional water purication system installed at the factory. It eradicates
germs in the water that are resistant to chlorine-based chemicals using high intensity UV light. Although the water
sanitizer works automatically with your spa, 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 water sanitizer will run during
ltration.
For spas with a circulation pump, the water sanitizer will run with the circulation pump.
The spa’s control system is factory-programmed with one lter cycle that will run in the evening when energy
rates are often lower. The time and duration of the lter cycle can be set according to your needs. In addition,
a second lter cycle can be enabled. Filtration time may need to be increased with heavy bather load.
See instructions for setting ltration cycles on page 22 or page 29.
The water sanitizer is virtually maintenance-free. Once a year the UV light needs to be replaced. See page
46 for instructions. However, the water sanitizer is not a user-serviceable item and maintenance
must be performed by a spa technician. Have your service technician consult the manufacturer’s
instruction and service manual.
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 ltration.
For spas with a circulation pump, the ozonator will run with the circulation pump.
