AIRTUB | ICEHAB | HOW TO SET UP

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!

INTRODUCTION

Welcome to your AirTub, a portable and efficient cold therapy solution designed to enhance recovery and wellness. The AirTub combines an inflatable tub made from durable, double-wall drop-stitch material with a powerful external chiller, allowing you to enjoy cold therapy wherever you choose. With its ease of setup and versatile use, the AirTub is perfect for home use or on-the-go recovery. This manual will guide you through safe setup, operation, and maintenance to ensure you get the most out of your AirTub experience.

Attention

Once you have completed the installation according to the assembly instructions and connected all the components, the system is ready for operation — all that remains is to fill it with water.

Before filling the AirTub with water, make sure that its final placement is correct and that you have easy access to the bottom valve of the Tub (on the back side). Once filled with water, it cannot be easily moved, and to reposition it you would need to drain it manually.

Therefore, first assemble and connect all the components properly, ensure that its position is correct and convenient, and then fill it with water.

SAFETY INFORMATION

⚠️ IMPORTANT – AirTub Installation Guidelines

The location where the AirTub is installed and operated must meet specific requirements:

Ambient temperature must not exceed 35°C.
The unit must never be exposed to direct sunlight.
For indoor installations, the area must be properly ventilated.

Failure to follow these guidelines may result in damage to the unit due to improper use, and will void the warranty.

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

Always supervise children and pets around the tub.

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

🔹 Before You Start Installation

Before starting the installation of your system, it’s important to understand two key points that must be checked regularly on your ice bath. These are the only reasons that could potentially cause damage to the system if neglected:

Water Filter Check

Check the water filter every week. If it’s dirty, clean it thoroughly or replace it. If the filter becomes clogged with dirt and is not changed in time, there’s a serious risk of damaging the water pump or other critical components.

➤ As a reference: for systems used by 1–2 people daily, the filter should be replaced every 30–40 days at most.
Water Flow from the Top Outlet of the Tub

The top outlet (the top hole of the tub) should always have a constant water flow — meaning water must be blowing into the tub. You can easily check this by placing your finger on the outlet and feeling the flow.

📌 Detailed instructions on how to check and act on these issues are provided later in this manual.

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).

Screenshot 2025-02-26 at 17.18_edited.jp

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.

Screenshot 2025-02-26 at 17.20_edited.jp

Screenshot 2025-02-26 at 17.21_edited.jp

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 on, do not use any tools.

STEP 6: Pipe Connections

Connect C to the bottom slot of the AirTub (on the valve), use only your hand
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 valves on the AirTub.
The 1 black valve on the filter.

EXTRAS (UV, OZONE)

Skip this step If you haven't purchased UV or Ozone system.

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.

UV MANUAL

OZONE MANUAL

STEP 8: Pump's cable

Connect the pump cable to the port on the back of the chiller (the main switch should still be OFF).

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 connected to a water tap in your space to fill the AirTub. Fill it until the water level is 2–3 fingers above the marked maximum level line (inside the tub). The upper hole of the AirTub must be submerged in water by 2–3 fingers. Do not turn on the system until the AirTub is fully filled with water. The pump and chiller must never operate without water.

STEP 11: SYSTEM AIR RELEASE

Once the AirTub is filled with water, the filter needs to be purged of air.

To perform the air release, the entire system must be turned off (main switch on OFF).

A. Both valves on the AirTub must be open.
B. Open the small valve located on top of the filter. You will see the filter filling with water. After 2–3–4 seconds, water will begin to come out of the small valve — the moment it does, immediately close the valve. The air release is now complete. You can now turn the system back on; it’s ready for operation.

*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. First, the water pump starts — this means the water flow has just begun. Place your hand inside the AirTub, directly in front of the upper hole; you should feel water “blowing” out. Also, check for any leaks at all connection points now that the system is running. If you detect any leakage, immediately turn the system OFF, close the valves, and re-tighten the fittings securely.

2. The chiller will begin operating 3 minutes after startup. During its operation, you’ll see the snowflake icon appear in the top left corner of the screen and the fan icon in the top 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

After some time of operation, the filter will accumulate dirt, so you will need to replace the internal filter or wash it. To replace the filter without spilling the water inside, you can first drain the water from the filter by following the procedure below.

A. Draining water from the filter

When the system is running normally:

Step 1: Close the lower valve of the AirTub and immediately open the small valve on top of the filter. You will see air entering the filter and water draining completely from it.

Step 2: Once the water level in the filter has fully dropped, close the upper valve of the AirTub and turn off the main power switch on the back of the chiller.

The water inside the filter is now drained and it’s ready for replacement.

B. Opening the filter cap and replacing the filter

Step 1: Unscrew the cap of the filter.

Step 2: Remove and replace the internal filter cartridge.

Step 3: Put the filter back in place and screw the cap back on.

Step 4: Open the two water valves of the AirTub (top and bottom).

Step 5: Bleed the air from the filter (remove the air by opening the small black valve at the top of the filter).

Step 6: Finally, turn on the main power switch at the back of the chiller (do not turn the chiller on until you have bled the air).

📌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 from us.

Replacement Water Filter – Order

We recommend purchasing filters directly from us, as they are specifically designed to match the exact specifications of your AirTub. If you choose to buy additional replacement filters from local shops, please make sure they meet the specifications listed below.

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).

Step 3: Open ONLY the bottom valve of the Tub and let the water drain out.

When, at the end of draining, there is still some water left and you want to turn the AirTub upside down to let it drain completely, be very careful not to tilt it towards the side where the two valves are located. If the weight of the tub presses on the valves, there is a high risk they will break. For this reason, always turn it over from the opposite side.

*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.

💧🔁 WATER FILTER – INSTRUCTIONS / AIR & CORRECT OPERATION

The filter must always contain water. During normal operation, the water level should be at least halfway up the filter, ideally to the top. If you notice the water level is very low or empty, perform air bleeding (see Step 11 in the guide).

If after bleeding and a few hours pass the water level drops again well below the middle, it means something hasn’t been installed correctly. In that case, check the following step by step:

Switch the system to OFF and follow all steps below.

1: The lower valve on the AirTub (the one that sends water to the filter) may need to be tightened a bit more. Try turning it a little more by hand — do not use tools. Tighten it just until it no longer turns easily by hand, without applying excessive force.

2: The fitting you attached to this valve (the metal part) might also need slight tightening. Again, only by hand, and do not overtighten.

3: Make sure the filter cap (the clear plastic one) is securely tightened. If needed, tighten it a bit more.

At this stage, perform air bleeding (see Step 11) and restart the system. If after some time the water level in the filter drops again below the middle, continue with the next steps.

Turn the system OFF again and follow the rest.

4: Close both valves of the AirTub and open the filter (unscrew the transparent plastic lid). Replace the current water filter with the replacement one we have provided. Screw the lid back on tightly, only by hand, as far as it goes, without using any tools. Perform air bleeding (see Step 11 of the manual) and restart the system.

If after all that air continues to enter the filter and the water level drops again below halfway, please contact us for further support.

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.

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.
