General Chiller FAQs
Can I control the chiller via an iOS / Android mobile app?
Where specified, our chiller units can be connected to your Wi-Fi and controlled remotely by the Tuya Smart & Smart Life mobile apps*.
Can I use the chiller outside if it rains?
Where specified, our chiller units are designed to be water resistant and rated for outdoor use, ensuring reliable outdoor performance.
However, for your safety and the safety of others, make sure the chiller is plugged into an AC socket that is appropriate for outdoor use, properly grounded, has a built-in surge protector, and ideally is IP65 rated.
Always turn off the chiller before starting your cold water therapy session. While where specified, our chillers have an IPX rating for water resistance, it's still recommended to keep them dry at all times.
Do not immerse, splash, or spray the chiller unit with water.
Can I add Bromine to the water?
Yes you can!
If you'd like the water to last longer, using Bromine tablets or powder should extend the usable time up to 1 month.
Bromine is more skin-friendly and lasts longer than Chlorine in cold water and you'll need very little to be effective.
Does the chiller need to be left on?
We recommend keeping your chiller on when the ice bath is not in use. This allows it to continuously filter the water, ensuring freshness.
The chiller automatically turns off once it reaches the set temperature, optimizing energy efficiency.
But remember, for safety, to always switch off the chiller unit during your ice bath session.
Is Ozone water treatment bad for the environment?
Ozone water treatment is far better for the environment than using Chlorine!
The built-in internal Ozone water treatment device on the Thermo CT2 chiller quickly breaks down into Oxygen when it makes contact with water, helping to quickly clean away microbes.
How long does the Ozone last?
The Ozone generator in the CT2 chiller activates roughly every hour for 5 minutes at a time. This can be adjusted higher and lower depending on requirements.
We recommend the chiller is left on at all times to keep the water moving and the Ozone active.
How do I maintain the chiller?
How do I maintain it, is it like my car AC, and needs to be re-gassed every year or so?
Maintenance purely lies with the filters, cleaning the metal mesh in the chiller, and replacing the particle filter.
The heat pump system is fully sealed and leak tested, and should never need to be maintained. The main flow and priming pumps have an exceptional lifespan, and are expected to last for more than 10 years of continuous use.
What happens if there is a fault with the chiller, and how do I tell?
In general, the only aspects that can go wrong are dirt and debris clogging up the filters and eventually passing into the internal systems.
This results in poor flow, and eventually no cooling. Should this happen, you can flush the system with a strong flow of water and later we'll have a cleaning product available for this.
We have a 1 year warranty that covers any manufacturing issues, and we will soon be offering a service plan for our engineers to visit and resolve any issues.
