Palmingo Pools Winter Freeze Checklist
Before the Freeze
✔ Confirm freeze protection is enabled
In the iAquaLink app, look for “Freeze Protection Mode” near the pump icon.
Make sure your system is connected to WiFi and communicating.
✔ Check pump and equipment power
Ensure breakers are ON and equipment is running normally.
Verify no error messages or communication failures.
✔ Turn off skimmer valves
Close the skimmer line so the system pulls warmer water from the main drain.
This reduces icy water entering the plumbing.
✔ Set heater to bypass
Turn the bypass valve so water does not flow through the heater.
Optional: remove heater drain plugs to release any standing water.
✔ Remove debris from the pool
Clear leaves or obstructions that could affect skimming and circulation.
During the Freeze
✔ Monitor Freeze Protection Mode
Pumps should run automatically at ~2,230 RPM.
Active schedules will be overridden—this is normal.
✔ Do NOT run your heater
Manufacturers advise against running heaters during freezing weather.
Freeze Protection Mode will shut the heater off automatically.
✔ Keep the pool cover managed
If snow is present, gently remove it to prevent excess weight.
If it’s just a freeze (no storm), keeping the cover on helps retain heat.
Your cover should still open—covers do not prevent freezing.
✔ Check for strong water flow
Listen for normal pump operation.
Confirm returns are pushing water into the pool.
✔ Insulate exposed plumbing (optional extra protection)
Use pipe insulation, foam sleeves, or moving blankets + duct tape.
Prioritize pipes and unions directly on the equipment pad.
If Power Is Lost (Rolling Blackout or Outage)
✔ Immediately turn off breakers to the equipment
Prevent pumps from trying to restart frozen.
✔ Drain equipment
Remove drain plugs from:
Pumps
Filter
Heater
Any exposed PVC low points
✔ Open all valves
Allow water to move out freely and relieve pressure.
✔ Cover exposed equipment
Use blankets, padding, or insulation until power returns.
After the Freeze Breaks
✔ Inspect equipment for cracks or leaks
✔ Reinstall drain plugs (if removed)
✔ Return valves to normal operating positions
✔ Confirm freeze protection mode has ended and schedules have resumed
✔ Check pump priming and system pressure
If anything looks or sounds unusual, contact Palmingo service before restarting your system.
Quick Reference: What NOT to Do
✘ Don’t run the heater during a freeze
✘ Don’t let water sit motionless in pipes
✘ Don’t force the pool cover open if ice has formed on top
✘ Don’t wait until temperatures drop to start checking equipment
✘ Don’t assume freeze protection will run if power is out
