Yes, however, both must be winterized if you plan to keep it in weather below 34°F.
To winterize the chiller, turn the chiller on its back (with the inlet and outlet valves facing downward) and empty all the water from the machine. Remove the blue filter casing (v.1 chiller) or open the filter housing and remove the filter from the top of the chiller (v.2 chiller) and make sure the chiller is completely dry before allowing it to be exposed to freezing weather. We do recommend covering with a tarp for extra safety measures.
To winterize the plunge, drain it fully and allow it to dry.
