Many cold plunges on the market suffer from performance issues, especially with their chillers, due to unclear maintenance guidelines and being pushed beyond their intended capacity. Without proper care, filters clog, water quality deteriorates, and chillers struggle to maintain target temperatures.

Found—Space has designed the Yirri Cold Plunge with the Found—Space Cooling Engine to outperform and outlast many competitors, thanks to its robust engineering and clearly defined maintenance and usage requirements. By following these simple protocols, you’ll ensure long-term reliability and peak performance from your Yirri.

Water Quality

Given that your cold plunge deals with a relatively small body of water, it’s important to monitor water quality carefully. Despite the built-in filtration and sanitisation system, the water can deteriorate faster depending on several factors:

• Entering Sweaty or Dirty: Always rinse off before entering the cold plunge to avoid contaminating the water.
• Dirty Feet: Ensure your feet are clean before stepping in.
• Chlorination: Chlorinating the water can extend its lifespan.

Best practice is to leave your Cooling Engine on at your desired temperature 24/7 to maintain optimal performance.

Filter, Strainer, and Water Maintenance

The following maintenance steps must be performed every 10-20 plunges. It’s critical not to exceed 20 plunges or 4 weeks (whichever comes first) without maintenance.

1. Replace the filter cartridge. Filter cartridges cannot be cleaned and must be replaced.
2. Clean the strainer. If your Yirri is equipped with valves on the tub, you can perform this maintenance without replacing the water. However, it is good practice to replace the water at the same time as other maintenance items.

Timber Maintenance

The exterior timber of the Yirri Cedar is raw, untreated Western Red Cedar. It is naturally very durable, but like any timber product, without care, it will fade, crack, and change colour over time. This is perfectly normal and won’t affect the performance of your Yirri.

If you wish to maintain a fresh timber finish, we recommend oiling your tub every 6-12 months with a natural decking oil. The timber will go much darker when oiled.

Dusty Environment

If your Yirri’s chiller is in a dusty environment or if it’s not cooling as efficiently, it may need an internal cleaning. Dust can accumulate on the radiator inside the chiller, significantly affecting its performance. Cleaning the unit will help it run smoothly. Check your User Guide for more details.
