Taking tap water from 65°F to 50°F at that rate works out at roughly 3 to 10 hours on the 0.8 HP and 2 to 5 hours on the 1.0 HP.

The chiller comes with three 20 micron cartridges and the manual asks for a new one about every 20 plunges, or sooner when it is dirty or the flow drops. Balanced water needs a test kit, pH and alkalinity adjusters, and a sanitizer, and the manufacturer recommends changing the water at least once a week with a chiller, more often with heavy use, or every 3 to 5 days without one. The tub manual also asks you to consult a pool supply store before using pool chemicals, to let them dissolve fully before anyone gets in, and never to add them to an empty tub, and it notes that damage from improper chemical use is not covered.\u003c\/p\u003e\n  \u003c\/div\u003e\n\u003c\/section\u003e\n\n\u003c!-- ============ 08 ============ --\u003e\n\u003csection class=\"dcbk-tinted\" id=\"crate\"\u003e\n  \u003cdiv class=\"dcbk-c\"\u003e\n    \u003cp class=\"dcbk-eyebrow\"\u003eScope\u003c\/p\u003e\n    \u003ch2\u003eWhat arrives with the black barrel, and what you still need\u003c\/h2\u003e\n    \u003cp class=\"dcbk-lead\"\u003eThe tub arrives in a crate on a pallet.

The manual warns that alcohol, drugs or medication before or during a plunge may lead to loss of consciousness with the possibility of drowning. Enter feet first and breathe steadily, without holding your breath or hyperventilating, and get out at once if you feel weak or lose control of your hands, arms or legs. The manual notes that prolonged immersion below 70°F risks hypothermia and that core temperature can keep falling after you get out, so do not drive or operate tools or heavy machinery straight afterwards.
