What owning chillers involves
OwnershipWhat it means
UpkeepThe filter is checked and cleaned on usage, and replaced on the chiller manufacturer's schedule rather than a general one. Ozone or UV built into a chiller reduces the chemical load but the sources are explicit that it does not replace sanitiser on a shared or heavily used tub. Water chemistry still applies to the tub it serves.
What you rebuyReplacement filter cartridge (interval per the chiller manufacturer)

These apply to the class, not to this record alone, and they are sourced from the manufacturer guidance for it. Anything a source does not state is left out rather than estimated.
