Proper installation ensures your chiller starts up smoothly and operates without errors. Taking a few minutes to follow these steps carefully helps prevent malfunctions and leaks, keeping your system running efficiently from day one.
- Approved water additive: The only product recommended for water maintenance is food-grade hydrogen peroxide.
👉Visit our Quick Water Maintenance Guide for safe dosing instructions. Avoid using off-the-shelf cold plunge sanitizers such as Sirona Simply Sanitizer or Ouster Cold Plunge Weekly Treatment. These products have caused corrosion and internal damage to cold plunge units and are not safe to use for your Icebound Pro Chiller, voiding the warranty.
- Built-in ozone system: Your unit already includes an integrated ozone system for water sanitation. Do not add any external ozone generator. Excess ozone can corrode internal components and void the warranty.
- Cold-weather caution: Do not operate the chiller in freezing conditions. For off-season storage and protection, follow the Winterization Guide.
- Hold on to your wooden crate and cardboard box; they’ll come in handy if your unit ever needs servicing or shipment.

Now let's get started!
(follow each section as indicated)
Main Filter Assembly
- Make sure the filter house O-ring is in place (see image).
- Insert the filter cartridge into the clear filter housing.
- Fill the housing halfway with water to help prime the pump.
- 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
- Wrap 2–3 layers of PTFE (Teflon) tape around the threads of both ports.
- Install the thick O-ring provided with your chiller accessories around the inlet port. This ensures a proper seal.
Strainer Base
- Separate the clear strainer housing from the black base.
- Screw the black base onto the inlet port until it’s almost hand-tight.
Final Assembly
- Attach the clear strainer container.
- Hand-tighten the assembly.
- Check that the clear lid is pointing to the ground (4 to 8 o'clock position is acceptable for proper water flow).
Prepare Water Hoses & 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 Hoses
- 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.
Power the Chiller
- Plug into a 120 V/15 A outlet (standard U.S.).
- Use a dedicated circuit. No power strips.
Test the Safety (GFCI) Plug
- Press Test: the light goes off.
- Press Reset: the light comes back on.
Turn It On
- Hold the unlock button on the LED panel.
- Set your desired temperature.
- Hold the power button to start.
- The pump will start immediately (you’ll hear a click) and run for 30 seconds during the initial priming cycle.
Initial Prime Cycle
- 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.
- One minute after startup, the pump will restart along with the fan and compressor.
Switch Between °C and °F
- Unlock the screen.
- Hold the mode (three lines) and + keys for 6 seconds.
- Use + to reach P08.
- Press unlock to edit.
- Choose: 0 = Celsius, 1 = Fahrenheit.
- Press unlock to save.
- Exit by holding mode + + for 6 seconds or wait 30 seconds.
You can also easily change the temperature unit without entering the factory settings:
- Unlock the chiller (if it's locked).
- Press and hold the “+” button and the “Unlock” button at the same time.
- 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
