**Tub Is Overheating**
If you find that your spa seems to be overheating, especially during the summer months, change the FD setting on the filtration cycle from FD2 to FD1. This will halve the amount of hours that your pumps are running for and will reduce the heat inside the cabinet of the spa. When the weather cools, return the setting to FD2.
WATCH: Due to the amazing efficiency of our HeatLock® system, in warmer summer months, you may need to make some adjustments to reduce your Arctic Spa temperature.

These doors release some heat from inside the cabinet to moderate water temperatures.
