Pool Freeze Protection
Your Pentair system will automatically go into Freeze mode when the outside temperature reaches approximately 34° F. The pool functions will cycle on and off. While in freeze mode (if you have a spa) the control panel will run back and forth between pool and spa mode. We recommend turning your pump speeds down from your mobile app. While in spa mode, the RPMs are generally much higher, which is not necessary when in Freeze mode. Turn the speeds down to about 1200 RPMs while the weather passes in preparation of freeze mode. After the cold weather passes, you can put back to normal speeds.
You will not be able to turn anything off or make any changes while the system is in Freeze mode. The only way to turn anything off is by turning the breaker off on the control panel. THIS IS NOT ADVISED. The pool will sense the safe temperature in which to resume normal functions and will automatically come out of freeze mode. As a precaution, we also recommend you wrap your fill line at the spigot to the pool.
It is not necessary, nor will it help, to heat the pool prior to or during a freeze.
If power is lost and you do not think it will return before temperatures have risen to a safe level, you can take the following steps to winterize your pool equipment:
1. Turn off breaker to pumps.
2. Remove pump basket lids.
3. Remove plugs on bottom of pump.
4. Open the pressure gauge on top of the filter. (Twist counter-clockwise to open it.)
5. Remove black 1.5" plug on bottom of filter.
6. Remove plug on heater manifold.
7. Cover equipment with blankets. (Be sure to remove blankets when starting equipment back up.)
8. Do not forget to wrap / protect fill lines and sprinkler lines.
It will be difficult, if not impossible, to restart the equipment once the power returns until the freeze has thawed out, so you must use your own judgement on whether or not to take these steps.
