Beginner's Guide to Ice Baths
If this is your first time using an ice bath, here are a few tips to help you get started:
-
For a while, until you get used to it, set the temperature to 10 degrees.
-
Before getting into the ice bath, take a warm shower.
-
A key requirement is to have peace and quiet in your space, with no one talking to you, and avoid hearing conversations, as this can distract your mind.
-
Get in quickly without thinking, within 4-5 seconds.
-
Do not submerge your arms past your wrists first.
-
Play some music, it will help the time pass faster.
-
Once you’re inside, stay still and remain motionless.
-
The first 10-20 seconds your body adjusts to the temperature and accepts the cold, so after 20 seconds, you won’t feel cold anymore, and you'll be fine.
-
Once you’re in, breathe slowly and deeply, both in and out. Don’t let yourself pant or breathe quickly. Try (it’s easy) to breathe very slowly for the first 30-40 seconds.
-
Start by sitting in for 1-3 minutes. Over time, as you get used to it, gradually increase the duration up to 5 minutes. Once you're comfortable with that, you can start lowering the temperature during future sessions.
-
Basic step: Once you finish your cold therapy session, it's recommended to stay standing and frozen outside the ice bath for 5-10 minutes. After this time, take a warm shower to bring your body temperature back to 100%.
*TIP: If it's summer and it's very hot outside, try skipping the warm shower to restore your body temperature, and you can stay in the summer heat for 4-6 hours without getting hot.
Enjoy your recovery session!

SAFETY INFORMATION
Electrical Safety
-
Warning: Do not connect or operate the ice bath in a power outlet if the electrical panel of your home or the location where you are using the device is not equipped with a Residual Current Device (RCD) or Ground Fault Circuit Interrupter (GFCI) and proper grounding. According to the law, all homes and facilities must be equipped with an RCD/GFCI anti-electrocution system in their electrical panels. If your electrical panel does not include such a system, do not plug in the ice bath until you contact a licensed electrician to install the appropriate safety device.
-
Do not handle electrical plugs with wet hands to avoid electric shock.
General Safety Guidelines
-
Never operate the system without water. Ensure the Tub and circulation system are fully filled before powering on the chiller.
-
Never operate the chiller without connecting the water pump. Ensure the pump’s power cable is connected before starting the chiller. If the pump cable is disconnected, immediately turn off the main power switch of the chiller.
-
Do not operate the system with closed valves. Always ensure water circulation is active and valves are open before starting the chiller.
-
Do not place the chiller in direct sunlight or in a high-temperature environment (e.g., room temperature above 35°C or a sealed space), as this may cause slow refrigeration or failure.
Water Safety
-
Keep the chiller away from direct water contact and ensure proper ventilation to prevent overheating.
-
Place the inflatable Tub on a smooth surface free of sharp objects. Avoid overinflating and inspect regularly for damage.
Supervision
-

COMPONENTS OVERVIEW
Filter, Pump, Pipes
Parts

YOU WILL NEED: POWER STRIPS (NOT INCLUDED)
-
If you purchased the AirTub only, (without UV or Ozone), you will only need a single power outlet for the entire system at your place.
-
If you purchased a UV or an Ozone system along with your AirTub, you will need a power strip with two outlets. This is because both the AirTub and the UV or Ozone need to be connected to the same power strip, allowing you to turn them off together if needed.
-
If you purchased both a UV and an Ozone system along with your AirTub, you will need a power strip with three outlets. This is because the AirTub, UV, and Ozone all need to be connected to the same power strip, allowing you to turn them off together if needed.
YOU WILL NEED: WATER HOSE (NOT INCLUDED)
-
You will need any hose that is long enough to reach from a water tap to the airtub in order to fill it. Be sure to choose the location carefully beforehand, as once it is filled, it becomes very heavy and cannot be moved.
💡Smart Control APP
-
If you have also purchased the Smart Control system we provide for the airtubs, you must plug the Smart Control into the power outlet and then connect the airtub to the Smart Control.
-
If you are also using a UV or ozone system, meaning you're using a power strip, you should connect the power strip to the Smart Control.
-
Important: Do not connect only the airtub or only the UV or ozone system to the Smart Control. The entire system must be connected through the Smart Control.

SETUP & INSTALLATION
STEP 1: Location and Preparation
-
If you choose to set up the ice bath indoors, such as in the living room, we recommend placing 1-2 thick towels or a small blanket underneath the tub, shaped into a circle (matching the size of the tub). This is because, when using the ice bath at very low temperatures (below 8-10°C, e.g., 3°C), the warmth of the indoor environment might cause moisture to form underneath the tub, which over time could damage your flooring (e.g., if it’s wooden). By placing the recommended items underneath, you create an insulating layer between the tub and the floor, preventing moisture buildup.
Important note: The towels are not meant to absorb the moisture but to prevent its formation altogether. -
Choose a flat, clean surface for the Tub, ensuring the area is free of sharp objects.
-
Place the chiller on a flat surface, away from water sources and protected from rain or excessive moisture
STEP 2: Unboxing and Setup
-
Open all the boxes and take out both the inflatable tub and the chiller
The chiller should never be laid on its side or turned upside down. When removing the chiller from its box, ensure that it is handled carefully and kept in an upright position to avoid potential damage.
If the chiller is accidentally turned upside down, it must be placed upright and remain in that position for 24 hours before being operated. This allows the internal components to stabilize and ensures proper functionality. -
Attach the filter unit to the left side of the chiller. There are small notches on the metal base of the filter that snap into place on the chiller
-
Use the air pump to fully inflate the tub until it is stable and firm. Fill the system to a pressure of 10 PSI (as indicated on the pump gauge)
STEP 3: Tub Placement Guide
-
After inflating the Tub, place it in the desired location. Plan carefully where to position it beforehand, as once filled with water, it becomes too heavy to move. Ensure that the orientation of the water inlet and outlet hoses from the Tub is not against the wall. The connection points of the Tub where the hoses attach should be slightly angled (as shown in the reference photo) and facing the direction where you will place the chiller. This positioning prevents the water hoses from bending or creating sharp angles.Therefore, make sure the Tub is correctly positioned before starting to fill it with water.
STEP 4: Upon the chiller
-
First, remove the two caps on top of the chiller (Image 1). By removing them, 2 rubber rings will remain from each cap you take off (Image 2).
-
After removing the two caps, place one rubber ring back onto each socket as shown in the image 3 & 4 and then tighten these two components firmly by hand (Image 5). Do not use any tools—tighten them only with your hand.
STEP 5: On the Airtub
Take these two valves and screw them tightly onto the Airtub, into the two holes (one on top and one on the bottom). Tighten them by hand only—do not use any tools. If your model has three holes, screw the valves into the top and bottom ones. The purpose of the middle hole will be explained later..
*If your TUB has 3 tube sockets, you should place one plug (found among the included accessories of the AirTub's plastic Bottle) into the middle socket. This slot is reserved for future use, in case you decide to upgrade to another model of our chillers that requires this connection.
For now, simply place the plug.
*If your TUB has tube 2 slots, just ignore this.
STEP 6: Pipe Connections
Connect C to the bottom slot of the AirTub (on the valve).
Connect D to the inlet of the chiller.
Connect A to the outlet of the chiller.
Connect B to the top slot of the AirTub (on the valve).
STEP 7: Turn Off all the valves
At this stage, make sure that all the valves in the system are turned off, because in the next steps, you will be filling the AirTub with water.
There are 3 valves to turn off:
-
The 2 red valves on the AirTub.
-
The 1 black valve on the filter.
EXTRAS (UV, OZONE)
If you have NOT purchased our UV or Ozone system, skip this step.
-
If you have any of them (UV or OZONE, please click on the buttons to proceed with their installation.
-
After you finish with these installations, come back to this page and continue with the next steps below
*Note: The UV and the Ozone installation should only be done after completing the previous setup steps.
STEP 8: Pump's cable
Connect the pump's cable to the power socket at the back of the chiller.
STEP 9: Main power cable
Connect the power cable and make sure the on off switch at this step is turned OFF. Don't turn on the chiller yet
STEP 10: Now it's time to fill the Tub with water
Use a hose from one of your faucets and fill the tub with water up to the line that marks the water level limit.
While filling the Airtub, be cautious and check for any leaks as the water level reaches each valve.
-
When the water reaches the first valve, inspect for any leaks.
-
When the water reaches the second valve, check again.
If you notice any leakage, stop filling immediately.
STEP 11: Air Removal from the system
Once the AirTub is filled with water, the filter must be bled (air removed from the filter).
To perform the bleeding process, the entire system must be turned off (switch in OFF position).
A. Open both red valves from the AirTub.
B. Open the small valve on the filter. Initially, you will see the filter filling with water. After 2-3-4 seconds, water will start coming out of the small valve, at that moment, close it immediately. The Air Removal process is complete.
*Sometimes, air may enter the filter, causing the water level inside to drop below the halfway point. Check it regularly. If this happens, simply follow this step every time you see air in the filter.
STEP 12: At the back of the chiller, turn the switch to the ON position.
Method of use:
1. The water flow has just started running. Check if there is any leakage now that the system is working.
2. The compressor starts running approximately 3 minutes after booting up. During operation, a snowflake symbol appears in the upper left corner, while a fan symbol appears in the upper right corner.
STEP 13: Set the Thermostat Settings
Set your desired water temperature:
Press S key once and then adjust the preferred target temperature with arrows ▲▼
*DO NOT SET THE DESIRED TEMPERATURE BELOW 3°C, (this model cannot work below 3°C, damage can be done)
---------------------
OTHER SETTINGS - We recommend not changing any settings from P0 to P6.
Press S for 5 seconds.
Use the ▲▼ buttons to navigate from P0 to P6.
Press the S button again to enter a "P" setting, and use the ▲▼ arrows to change the value.
P0 = C
(Select cooling or heating mode. This model is for cooling.)
P1 = 3.0
(Temperature difference. When the chiller reaches the desired temperature, this setting determines after how many degrees it will start cooling again.)
Example: If P1 is set to 3 and the desired temperature is 7°C, the cooling will stop when the water reaches 7°C and restart when the temperature rises to 10°C.
P2 = 110
(High-temperature warning for the chiller box. If the temperature exceeds this value, the chiller will not operate.)
P3 = -50
(Low water temperature warning.)
P4 = -2
P5 = 3
(Protection delay. This means that after starting the chiller, the machine will begin operating after 3 minutes, protecting it from damage due to rapid power fluctuations. If set to 5, it will start operating 5 minutes after activation.)
P6 = C
(You can select Celsius (C) or Fahrenheit (F) based on your preference.)
At the end of the installation, you may notice some spare components are left. These are included for future use or in case replacements are needed.

FILTER REPLACEMENT & WATER DRAINAGE
Water filter replacement
After several months of operation, the filter will accumulate dirt, so you will need to replace its internal cartridge.
Step 1: Turn off the power switch at the back of the chiller.
Step 2: Close the two red valves on the Tub (top and bottom).
Step 3: Unscrew the filter cap (a small amount of water will spill; wipe it with a towel).
Step 4: Remove and replace the internal cartridge of the filter.
Step 5: Screw the filter cap back on.
Step 6: Open the two water valves on the TUB (top and bottom).
Step 7: Perform venting of the filter (remove the air with the black small valve up on the filter) .
Step 8: Turn the AirTub operation back ON.
📌Inside the chiller package, we have included a replacement water filter.
This is meant to cover your first filter change, so your system is never left without filtration while you purchase a new one.
You can buy a compatible filter from any water filter or plumbing store in your area.
The cost is very low — around 2 to 4 euros, depending on the store.
Attention: You must purchase exactly the filter shown in the photo, with the woven fibers around the edges and the following specifications.
Filter Specifications:
-
Length: 5 inches / 12.8 cm
-
Filtration: 20 micron
Draining the water out
Step 1: Set the system to OFF and turn off all the valves OFF
Step 2: At the bottom valve of the Tub, remove the hose from the valve. (Do NOT unscrew the valve from the Tub, only the hose). Some water may leak from the hose you just removed, but it's ok use a towel.
Step 3: Open ONLY the bottom red valve of the Tub and let the water drain out.
*If you want to drain the water further away from the tub, for example, to a balcony, we have already provided you with a quick connector (see image). You can attach a hose from your home to this connector (if you don't have one, purchase a 12mm garden hose) and connect it to the bottom valve of the AirTub as an extension.

OPERATION INSTRUCTIONS
1. Operating the Chiller
-
When you first power on the chiller you need to allow time for the water to reach the set temperature. This may take several hours depending on ambient conditions.
2. Entering the Tub
-
Ensure the tub temperature is at your desired level. Shower before entering to maintain water clarity and hygiene.
3. Post-Use Recommendations
-
Keep the tub filled and the chiller on to maintain efficiency for daily or weekly routines. Close the lid after use to retain the target temperature.
4. If you have the AirTub indoors and want to lower the temperature below 8-10°C, you may notice that the filter exposed to the indoor air will start to sweat due to the temperature difference. This is normal because the indoor space is warmer. The temperature difference across the materials causes condensation. The AirTub and its pipes are insulated to prevent dripping, but the pump and the filter may produce condensation. What can you do? Cover the entire filter with a towel to prevent it from coming into direct contact with the air, which will stop it from sweating. Do the same for the pump.

Icebath Cleaning & Maintenance
Water Hygiene
The water in your icebath functions like a living organism, as it comes in direct contact with your body. That’s why it requires regular maintenance to stay clean and safe for use.
1. Water Check
You should check the condition of the water at least once a week. If the water changes color, clarity, or smells unpleasant, it most likely needs to be replaced.
2. Based on your cleaning system:
a. Icebath with basic water filter (no UV or Ozon):
-
The water should be replaced every 3 to 4 weeks.
-
The water filter should be checked weekly:
-
If it is filled with dirt, hair, or has become dark, it must be cleaned or replaced.
-
A clogged filter restricts water flow, reduces cleaning efficiency, and may lead to pump damage.
-
🛑 Important: If the filter is not cleaned or replaced for an extended period and becomes fully blocked, dirt may enter the pump or cause overheating.
In such cases, the warranty does not cover pump damage, as it results from improper maintenance.
b. Icebath with UV or Ozon system:
-
Water replacement can be extended to every 2 to 3 months, depending on how often and how cleanly the bath is used.
-
It is strongly recommended that you shower thoroughly with soap before entering the icebath.
-
The filter maintenance and replacement routine remains exactly the same as above.
3. When you're not using the icebath for a few days
If you don’t use the icebath for 2–3 days or more, the water becomes stagnant, creating ideal conditions for bacteria to form.
👉 In such cases (or generally whenever you’re not using the bath):
-
Open the lid, and
-
With your hand, stir the water vigorously in a circular motion for 20–30 seconds to create a swirling effect.
This helps with oxygenation and prevents stagnation.
4. If you have Smart Control
If you've purchased the Smart Control system and choose to keep the icebath turned off for several days, keep in mind:
-
No water cleaning occurs while the unit is off.
-
Water remains completely still and its lifespan is significantly reduced.
-
Manual stirring (as described above) becomes even more critical in this case.
5. Airtub Cleaning During Water Changes
Every time you drain the icebath and refill it with fresh water, it is essential to also clean the inside of the Airtub:
🧽 Use a sponge with a little bleach and water to thoroughly disinfect the interior surfaces.
💦 Then, rinse thoroughly with plenty of clean water to remove all bleach residue.
The bleach is necessary to properly sanitize the material of the Airtub and ensure it stays hygienic for the next use.
6. Final Note – Caution:
Do not keep the same water beyond the recommended timeframes. Long-term water use can lead to bacterial growth and increase the risk of contamination, which can negatively affect your health.
Chiller Maintenance (once a year)
Proper maintenance of your chiller is necessary for optimal performance. The main cause of reduced performance is dust accumulation, which blocks proper cooling and ventilation. For this reason, we recommend cleaning your chiller at least once a year using professional air blowing.
If your chiller is outdoors or in a dusty environment, we recommend repeating this procedure every 6 months.
Chiller Cleaning Procedure
-
Completely turn off the system.
-
Close all valves.
-
Detach the filter from the chiller.
-
Place the plugs back on the two chiller ports and take it with you.
-
Transport the chiller to the cleaning area without tilting or inverting it.
-
For cleaning, a strong air blow inside the chiller is required. If you do not have professional air blowing equipment, you can take it to a gas station with a strong air blower. Blow air from all sides, including the back where the fans are located. Make sure to remove all dust without tilting or inverting the unit.
-
After cleaning, reconnect the chiller to your system.
11
DURING HARSH WINTER
-
If you have an airtub or ice bath placed outdoors, keep in mind that during winter, when temperatures drop below freezing (e.g., below 0°C), you must never turn off the machine. If the system is turned off, the water in the pipes could freeze and cause damage. Some customers have mistakenly turned off the machine, thinking that the cold weather outside would cool the water naturally. However, the machine doesn't just cool the water—it also ensures constant water circulation, preventing it from freezing. So, always keep the machine running to maintain water flow and avoid freezing or potential damage to the system. Additionally, if the outdoor temperature drops below -1,-2°C, you’ll need to move the machine indoors until the extreme cold weather passes. The process is simple: close all the valves of the tub, disconnect the hoses, and move the machine to a warm indoor space (you can leave the tub outside with the water, as it won’t be damaged). By following these steps, you can ensure the system remains safe during cold weather conditions.

TROUBLESHOUTING
-
The Pump Is Making Extra Noise as If It's Not Working Properly
-
If you hear an unusual noise coming from the pump, it means that air has entered the filter. This can happen for various reasons, such as a sudden movement of water when you enter. It is completely normal and easy to fix. The filter needs to be bled. This may happen frequently and is not a problem. Simply perform Step 11.
-
-
Problem: Water is not circulating (Place your hand inside the tub, in the upper hole where the hose connects, but from the inside. Make sure the water is flowing properly.)
-
Solution2: Check that the filter is filled with water up to the halfway point. If it contains less, it needs venting (Step 14).
-
Solution3: Check if the hose is bent or kinked anywhere, as this could block proper water circulation.
-
Solution4: Check the pump and ensure it is securely connected and working (hearing the sound of working)
-
-
Solution1: Make sure that the filter is on the floor and not somewhere high up. The filter should be at the same level as your tub. If it's at a different height, there will be an issue with water circulation and venting.
-
Problem: Temperature is not reaching the desired level.
-
Solution1: Verify the thermostat settings and check for any obstructions in the filter or tubing.
-
Solution2: Check if the hose is bent or kinked anywhere, as this could block proper water circulation.
-
Solution3: Check that the cooling symbol
-
in the thermostat is shown, if not then repeat the (Step 17, P0 setting)
-
-
Problem: Leaking from connections.
-
Solution: Tighten all connections again.
