Q&A
Q:How do I use the external filter with the chiller system? 
A:Connect the chiller, pump, and tub. Open the filter’s air valve to let water flow in. When the water level inside the filter stabilizes and stops rising, close the valve and turn on the system for normal filtration and circulation. 

 

Q:What direction should I install the filter? 
A: Follow the water flow direction:

Tub Outlet → Filter IN → Filter OUT → Chiller IN → Chiller OUT → Tub Inlet

The bottom of the filter is marked with arrows indicating flow direction. 

 

Q:Is this filter kit compatible with other chillers or tubs? 
A:Yes, the kit is designed for AS ColdPlunge systems but works with any setup that uses 1/2" fittings and pipes. 

 

Q:How often should I replace the filter cartridge? 
A:We recommend replacing the cartridge every 2-3 weeks, depending on water quality and frequency of use. 

 

Q:Does the filter require any tools for maintenance? 
A:No tools are needed. The filter housing features a twist-off design, so replacing the cartridge is quick and easy.
