Horizontal Tub - Cold Weather & Winter Care

Winterization Responsibility

If the tub is exposed to freezing temperatures, proper winterization steps must be followed. Failure to properly winterize the unit may result in damage to internal components, which is not covered under warranty.

Built-In Freeze Protection

Your Horizontal chiller has an internal freeze-protection heater designed to:

  1. Help protect the system from freezing in colder temperatures.
  2. Help maintain your set water temperature when the outdoor temperature drops below it.

Important: The freeze-protection heater provides added protection, but it does not eliminate the risk of freezing during extreme or prolonged cold weather. Continuous water circulation is essential.

Monitor Outdoor & Water Temperatures

Keep an eye on your local weather forecast and the temperature reading on your chiller.

20°F and above

If temperatures are expected to remain below 20°F for 48+ hours, we recommend taking action to prevent freeze damage.

Option 1: Pause Plunging — Winterize the Tub

  1. Drain the tub completely using the pump and hose.
  2. Once fully drained, unplug the tub to prevent the pump from running dry.
  3. Disconnect the chiller + filter and move it indoors. Gently tilt it to help drain any remaining water.
  4. Remove the filter housing, empty any trapped water, and move it indoors.
  5. Leave the tub empty until outdoor temperatures return to a safe operating range.

Option 2: Continue Plunging — Move Indoors

  1. Drain the tub completely.
  2. Disconnect the chiller and filter housing and drain any remaining water from each.
  3. Move the tub indoors.
    The tub weighs approximately 170 lbs dry with the chiller removed.
  4. Reinstall the chiller and filter housing.
  5. Refill the tub and resume normal use indoors.

Freeze damage caused by improper winterization or loss of water circulation is not covered under warranty.

⚠️ Important Safety Notes

  •  Continuous water flow is essential to help prevent freezing and protect internal components.
  • If draining the tub, unplug the unit and move the chiller and filter housing indoors to prevent freeze damage.
  • Freezing temperatures, power loss, or reduced/stopped water flow can cause standing water to freeze and damage components.
  • Monitor your chiller temperature. If the water drops below 38°F, follow the extreme cold weather steps above.
