Protect your chiller

Before You Begin

A few simple habits will help protect your chiller, keep your water clean, and prevent avoidable setup issues.

Important

Let the chiller handle sanitation

Your Icebound chiller uses continuous circulation, dual-stage filtration, and integrated ozone to help keep the water clean. Do not add Sirona Simply Sanitizer, Ouster Cold Plunge Weekly Treatment, or other unapproved sanitizers—we have seen corrosion in systems where these products were used. If you choose to add a sanitizer, use only food-grade hydrogen peroxide and monitor the level with compatible test strips.

01

Circulation

Keep the water moving

Run your chiller regularly so water continues cycling through the filter and ozone system. If you turn it off for an extended period, disconnect the hoses and allow the unit to drain rather than leaving warm, stagnant water in the lines.

02

Water chemistry

Test your water periodically

Check pH and total alkalinity to keep your water balanced and help protect the system. Proper alkalinity helps stabilize pH and reduces sudden swings. See our water maintenance guide for detailed water care information.

03

Cold weather

Protect the system from freezing

Do not operate the chiller when ambient temperatures are below freezing. If you are storing the system for the season, drain it completely and follow the winterization instructions.

04

Future service

Keep the original packaging

Hold onto the shipping crate, box, and protective packaging. You may need them if your chiller ever requires service or return transportation.

Get connected. Get cooling. Get ready to experience your first Icebound plunge.

Your Step-by-Step Setup Guide

Follow the same setup process with detailed written instructions and images. If you used the video guide above, you can keep this section handy as a quick reference.

Main Filter Assembly

1. Make sure the filter house o-ring is in place (see image).

2. Insert the filter cartridge into the clear filter housing.

3. Fill the housing halfway with water to help prime the pump.

4. Screw the housing onto the filter base by hand until snug. Use the filter wrench only if you ever need to remove it for maintenance; do not overtighten.

Strainer Installation

Chiller Inlet & Outlet

1. Wrap 2–3 layers of PTFE (Teflon) tape around the threads of both ports.

2. Install the thick o-ring provided with your chiller accessories around the inlet port. This ensures a proper seal.

Strainer Base

1. Separate the clear strainer housing from the black base.

2. Screw the black base onto the inlet port until it’s almost hand-tight.

Final Assembly

1. Attach the clear strainer container.

2. Hand-tighten the assembly.

3. Check that the clear lid is pointing to the ground (4 to 8 o'clock position is acceptable for proper water flow).

Prepare the Hoses and Fittings

Wrap PTFE (Teflon) tape around all male threads: 2–3 layers in a clockwise direction. This helps prevent leaks and protects the threads. Avoid over-wrapping; fittings should screw in smoothly by hand before final tightening.

Check the O-rings: Must be inside both ends of each hose or on the male threads of each fitting.

Thin O-rings. Go inside the tips of your water hoses. They seal the quick-connect fittings and replace pre-installed ones if needed.

Thick O-rings. Install this on the chiller inlet port before attaching the strainer housing body. When tightened, the strainer should face downward (4–8 o’clock position).

  • Install fittings and valves: Your chiller and tub boxes include fitting adapters inside each kit. We recommend using the adapters that come with your tub to connect the hoses. Hand-tighten each one into the tub’s inlet and outlet ports. Don’t overtighten.

  • If your tub has a third unused port, seal it with the included plug (also wrapped with PTFE tape).


For easier maintenance, install a ball valve on each tub port. This allows you to isolate the chiller during cleaning or service.

Connect the Tub and Chiller

  1. First hose
  • Connect from the chiller’s WATER INLET (at the strainer) to the tub’s lower port (Green to Red).
  • Tip: Fill this hose with water first so the strainer is completely full.
This avoids air pockets.

2. Second hose

  • Connect from the chiller’s WATER OUTLET to the tub’s upper port (Red to Green).

3. Fill the tub

  • Add water until it’s above both water ports before powering on.

Important Note on Hoses & Fittings

There are three correct ways to connect the tub and the chiller using the hoses. 

If your model is an Endurance Plunge, you can use either connection style because your kit includes both the small fitting and the 90° elbow with the 304 stainless steel nipple.

If your model is an Immersion Plunge or Endeavor Plunge, you must use the 90° elbow with the 304 stainless steel nipple, as these models do not include the small adapter.

Startup - Power On and Prime Your Chiller

Initial Startup and Priming

Power the Chiller

1. Plug into a 120 V/15 A outlet (standard U.S.).

2. Use a dedicated circuit. No power strips.

Test the Safety (GFCI) Plug

  1. Press Test: the light goes off.
  2. Press Reset: the light comes back on

Turn It On

1. Hold the unlock button on the LED panel.

2. Set your desired temperature.

3. Hold the power button to start.

4. The pump will start immediately (you’ll hear a click) and run for 30 seconds during the initial priming cycle.

Initial Prime Cycle

1. During priming, hold the red button on the main filter housing until it fills with water. The pump will run for 30 seconds, then pause for another 30.

2. One minute after startup, the pump will restart along with the fan and compressor.

Change Between °F and °C

  1. Unlock the screen.
  2. Hold the mode (three lines) and + keys for 6 seconds.
  3. Use + to reach P08.
  4. Press unlock to edit.
  5. Choose: 0 = Celsius, 1 = Fahrenheit.
  6. Press unlock to save.
  7. Exit by holding mode + + for 6 seconds or wait 30 seconds.

You can also easily change the temperature unit without entering the factory settings:

  1. Unlock the chiller (if it's locked).
  2. Press and hold the “+” button and the “Unlock” button at the same time.
  3. Hold for about 3 seconds until the display switches between °C and °F.

That’s it; your chiller will now show temperatures in the selected unit.

Temperature Set-Point Tolerance

Your chiller uses a temperature differential (menu code F01) to avoid constant fan operation and rapid cycling. The factory default is 2 °C (≈3.6 °F).

  • Example: If your target is 37 °F with the 3.6 °F default, the chiller cools to 37 °F, then the fan and compressor stop while the pump keeps running. Cooling resumes only when the water warms to 40.6 °F (target + differential).

  • Startup note: If the water is 39 °F and the target is 37 °F, cooling won’t start until it reaches 40.6 °F.

For tighter control, you can lower F01 to 0.2 °C (≈0.4 °F).

A 1 °F differential keeps water between 37 °F and 38 °F.

See sections 2.5 and 3 of the technical manual for adjustment instructions.

These alarms are safety features to protect your pump - there's no need for concern. The E11 alarm indicates low water flow, typically caused by air in the line or insufficient water flow to the pump. While E12 is temperature-related, it's often triggered by low flow conditions as well.

Check these items if you encounter either alarm:

Strainer Position and Fill

  • Must be 100% full of water
  • Install at approximately 90° angle with clear housing at bottom
  • Incorrect orientation can trigger low flow detection

Filter Housing

  • Should be completely full of water (some bubbles during operation are normal)
  • If not full, press and hold the red vent button on top until water flows from the vent

Hose Connections

  • Connect the chiller water inlet hose to your tub's lower water port
  • Verify all connections are secure

Water Level

  • Maintain water level above the port that connects to the chiller water inlet
