Learn how to replace the filter in your Frozin 400 cold plunge system to maintain crystal clear water.
Turn off and unplug the chiller so the pump is not running while the filter housing is open.
Unscrew the filter housing cap. Keep a towel handy as a small amount of water will drain out.
Pull the used cartridge straight out and dispose of it. Rinse any debris from inside the housing.
Slide in a new Frozin replacement filter, making sure it seats fully and the housing gasket is clean and in place.
Screw the cap back on hand-tight, power the chiller on, purge any trapped air and check for leaks. Replace filters every 2–4 weeks with regular use.
