Maintaining / Cleaning of your Cold Plunge System

Cleaning and Care of Your Cold Plunge

A cold plunge tub is a valuable addition to any home, gym, spa, wellness center, or recovery space. With proper cleaning, water care, and routine maintenance, your cold plunge system can continue operating efficiently while helping protect the tub, chiller, hoses, filters, and internal components.

Water quality, frequency of use, outdoor exposure, and local water hardness can all affect how often maintenance should be performed. Systems used in areas with hard water, high mineral content, or commercial environments may require more frequent cleaning and inspection.

How to Properly Maintain and Care for Your Cold Plunge Tub

Regular Cleaning

Keeping your cold plunge tub clean is essential to help prevent the buildup of bacteria, mold, dirt, and debris.

Use a mild detergent and a soft-bristled brush to clean the interior and exterior surfaces of the tub. Be sure to rinse thoroughly after cleaning and dry the surfaces with a soft cloth.

For best results, clean the tub regularly and remove any visible dirt, dust, leaves, or debris after each use. This will help maintain a cleaner plunge environment and reduce strain on the filtration system.

Water Maintenance

Always use clean, fresh water in your cold plunge tub. Poor water quality or hard water can contribute to mineral buildup, scale, and potential damage to the chiller, hoses, plumbing, and internal components.

Test the water regularly and maintain the pH level between:

7.2 – 7.8

Drain and refill the tub at least once per month, or more frequently depending on usage, water quality, and sanitizer levels.

In areas with hard water, additional filtration, pre-filtering, or more frequent system cleaning may be necessary to help reduce mineral buildup.

Filters and Water Circulation

Regularly inspect, clean, or replace the filters on your cold plunge system to ensure water is circulating properly.

A clogged, dirty, or deteriorated filter can reduce water flow, affect cooling performance, and place unnecessary strain on the chiller.

If your system includes jets or circulation fittings, inspect them regularly to ensure they are clear of debris and functioning properly.

Cover Use

Use a cover whenever the cold plunge tub is not in use.

A cover helps prevent dust, leaves, debris, and other contaminants from entering the water. It can also help reduce evaporation and assist with maintaining water temperature.

Recommended Maintenance Items

Hair Filter Inspection

Inspect the hair filter regularly to make sure it is free from debris, hair, scale, or other buildup that may restrict water flow.

If debris is present, remove the filter and rinse it thoroughly under warm or hot water. A toothbrush or small soft brush may be used to gently clean the mesh screen.

After cleaning, you should be able to clearly see light through the mesh portion of the filter before reinstalling it.

Water Filter Inspection

Inspect the water filter regularly to confirm it is clean and allowing proper water flow.

If the filter appears dirty, clogged, deteriorated, or water flow seems reduced, clean or replace the filter as needed.

A restricted or deteriorating filter can reduce flow through the chiller and may affect cooling performance.

Flow Rate Monitoring

For LUXE and PREMIER models equipped with a flow-rate display, monitor the flow rate during normal operation.

If the display shows a flow rate below 10 LPM, this may indicate a clogged filter, debris in the system, mineral buildup, or restricted water flow through the hoses or chiller.

If normal filter cleaning does not improve the flow rate, a deeper cleaning of the chiller and hoses may be required.

Hose Inspection

Inspect hoses regularly for kinks, blockages, collapsed sections, or debris that may restrict water flow.

Make sure all hoses are securely connected and positioned to allow smooth, unrestricted circulation between the tub and chiller.

Condenser Cleaning for Outdoor Use

If the machine has been used outdoors for three months or longer, clean dust and debris from the condenser.

A dirty condenser can reduce cooling efficiency and negatively affect the chiller’s cooling capacity. Regular condenser cleaning will help maintain proper performance, especially in outdoor or dusty environments.

Attention:
Outdoor use, dusty environments, pollen, leaves, and debris may require condenser cleaning more frequently than every three months.

Recommended Maintenance Schedule

Weekly Maintenance

Inspect both the hair filter and water filter to confirm that water flow is not being restricted by debris, buildup, or filter deterioration.

If either filter appears dirty or clogged, clean or replace it as needed to maintain proper system flow.

Monthly Maintenance

Perform a more thorough inspection and cleaning of the hair filter at least once per month, or more often if the system is used frequently.

Remove the hair filter and inspect the mesh screen for any debris, particles, or buildup. If debris is present, rinse the filter under warm or hot water until clean.

For best results, use a toothbrush or small soft brush under warm water to help remove any particles trapped in the mesh.

After cleaning, you should be able to clearly see light through the mesh portion of the filter. Once clean, reinstall the filter securely and continue using the cold plunge system as normal.

Deep Cleaning / Scale Removal Maintenance

Over time, mineral buildup from hard water may collect inside the chiller and hoses. This can reduce flow rate and may affect the performance or longevity of the system.

For LUXE and PREMIER models, if the chiller display shows a flow rate below 10 LPM, we recommend performing a deep cleaning of the chiller and hoses.

Recommended Deep Cleaning Schedule

For residential or home use, this cleaning process is recommended every 3 months.

For commercial or business use, this cleaning process is recommended every month, or more frequently depending on water quality, system usage, and local water conditions.

Chiller and Hose Cleaning Instructions

To clean dirt, scale, or mineral buildup inside the chiller, use a CLR cleaning solution diluted with water.

Mix the solution using the following ratio:

3 parts water to 1 part CLR

Pour the mixture into a small plastic bucket.

Do not pour the CLR mixture directly into the cold plunge tub, as the solution can create significant foam that may be difficult to fully clean out of the tub.

Place both water hoses directly into the bucket so the cleaning solution can circulate through the chiller and hoses.

Keep the chiller’s filter installed during this process to help capture loosened debris and improve cleaning effectiveness.

Turn on the chiller and set the temperature to:

35°C / 95°F

Allow the chiller to run for approximately 4 hours.

You do not need to continuously monitor the chiller during this process. However, if the chiller shuts off due to low flow or another safety feature, simply power the unit back on and continue the cleaning process.

After the cleaning cycle is complete, flush the hoses and chiller thoroughly with clean water before reconnecting the system to the tub.

Purpose of This Cleaning Process

This cleaning process helps maintain proper water flow through the chiller and reduces the risk of damage to internal components. It is especially important in areas with hard water, where mineral and scale buildup can occur more quickly.

Maintaining proper flow helps the chiller operate efficiently and protects the system from unnecessary strain.

Regular inspection and cleaning can also help identify potential flow restrictions before they become larger service issues.
