Important: A cooling and heating chiller is not included with the tub-only configuration. Water circulation, powered cooling and heating, Wi-Fi temperature control, filtration, and ozone sanitation require separately purchased compatible equipment.

Installation

The Dynamic Cold Therapy CUBOID is designed for installation on a smooth, level, stable surface capable of supporting the tub, water, and occupant. Before installation, verify that the selected area provides sufficient access to a water supply, suitable drainage, and space for safe entry and exit.

Foundation and Placement: The tub measures 50 inches long, 30 inches wide, and 31.5 inches high, excluding any additional space required for access or optional accessories. The manufacturer lists an empty weight of 178 pounds. Because water adds substantial weight, verify that the floor, deck, or foundation can support the complete filled installation and its intended users.

Indoor Installation: Position the plunge on a waterproof surface with suitable drainage and ventilation. Avoid carpeting, moisture-sensitive flooring, and locations where splashing or draining could damage nearby walls, furniture, or electrical equipment.

Outdoor Installation: Use a smooth, stable surface free of sharp objects and debris. The manufacturer recommends placing the tub in a shaded or covered location to reduce prolonged direct sunlight exposure. Provide drainage around the tub and follow the owner's manual regarding temperature limitations and weather protection.

Optional Chiller Installation: The CUBOID includes 3/4-inch inlet and outlet connections for compatible cooling and heating equipment. When adding a chiller, connect the tub outlet to the chiller inlet and the chiller outlet to the tub inlet, following the approved connection diagram. Confirm that the chiller and all hoses, valves, and fittings are compatible with the tub before installation.

Electrical Considerations: The tub-only configuration does not include an electric chiller or powered temperature-control system. Electrical requirements depend on the optional equipment selected. If installing a chiller, follow its separate installation manual and use a suitable grounded, protected electrical supply that meets applicable codes.

Initial Inspection and Filling: Inspect the tub, interior surface, valves, and plumbing connections for shipping damage before filling. Close the drain valve and fill gradually with clean water, checking for leaks. The manufacturer's manual recommends beginning with a lower water level and adjusting after accounting for displacement when the user enters.

Operation and Usage

The Dynamic Cold Therapy CUBOID provides a dedicated basin for cold-water immersion. Water temperature is determined by the water added to the tub or by a compatible optional cooling and heating system. The tub-only configuration does not independently chill, heat, circulate, or filter water.

• Preparing the Plunge: Fill the tub with clean water to a suitable level that allows comfortable immersion while keeping the head above water. Avoid overfilling, which can cause water to spill when entering.
• Optional Temperature Control: When connected to a compatible Dynamic Cold Therapy chiller, follow the chiller manufacturer's instructions to adjust water temperature and manage the cooling or heating cycle. Temperature settings and performance depend on the selected chiller.
• Safe Entry and Exit: Use the included Pacific Cedar step when entering or leaving the tub. Enter feet first, keep movements controlled, and maintain a steady breathing pattern. Never attempt breath-holding exercises while immersed.
• Session Duration: Start with conservative water temperatures and brief immersion sessions. Cold-water tolerance varies, and prolonged exposure can increase the risk of hypothermia even after leaving the water.
• Covering the Tub: Secure the included insulated cover and locking latches whenever the tub is not in use. Keep children and pets away from the plunge and never rely on the cover as a substitute for direct supervision or other safety measures.
• Water Chemistry: The manufacturer's owner's manual recommends maintaining water pH between 7.2 and 7.8. Test water regularly and use only manufacturer-approved water-treatment methods and products.
• Water Replacement: For systems without external filtration or water treatment, the manufacturer's manual recommends replacing water approximately every 3–5 days depending on use. Systems with optional chillers still require regular water testing, cleaning, and water changes according to the applicable equipment instructions.
• Cleaning: Drain the tub and wipe the interior using a soft cloth and a mild, neutral cleaning product approved by the manufacturer. Avoid abrasive brushes and harsh cleaners that could damage the interior surface.
• Draining: Use the dedicated drain valve to empty the tub into a suitable drainage area. Follow local requirements for disposing of water containing treatment chemicals.
• Storage and Weather Care: Empty and dry the tub before extended storage. The manufacturer advises against storing or operating it in freezing conditions and against prolonged direct sunlight exposure. Inspect the exterior, cover, valves, and connections regularly.

Important: Cold-water immersion can create substantial cardiovascular and respiratory stress. Avoid entering alone, and exit immediately if you experience dizziness, chest discomfort, breathing difficulty, weakness, or loss of coordination. Consult a healthcare professional before using cold-water immersion if you have cardiovascular concerns or other relevant medical conditions.
