The Inergize Cold Plunge Tub is a recreational cold or hot tub designed for personal use, featuring a chiller unit that regulates water temperature, circulates water, and filters it. The system includes an inflatable tub, a chiller, hoses, and various accessories for setup, maintenance, and operation.
Function Description:
The Inergize Cold Plunge Tub allows users to experience cold water immersion or hot tub relaxation. The chiller unit is the main component responsible for chilling or heating the water, circulating it through the tub, and filtering out debris. The system is designed for ease of setup and takedown, making it suitable for both permanent and temporary installations. The tub is inflatable, providing portability and convenience. A control panel on the chiller allows users to set the desired temperature, monitor system status, and activate various functions like Wi-Fi connectivity and ozone generation. The system also integrates with a mobile app (Tuya Smart) for remote control and scheduling.
Important Technical Specifications:
- Power: The chiller operates on a standard 120V/60Hz electrical circuit with a 15 amp minimum circuit. It is equipped with a ground-fault circuit-interrupter (GFCI) for safety, which must be tested before each use.
- Temperature Range: The chiller can reach minimum or maximum temperatures in approximately 3 hours, depending on ambient temperature and set temperature.
- Water Flow: The control panel displays water flow in liters per minute. A flow error ("FL") indicates low water flow.
- Tub Inflation: The tub should be inflated to 10 PSI using the Double Action Air Pump.
- Wi-Fi Connectivity: The system supports 2.4 GHz wireless networks for app integration.
- Chemical Exposure Warning: The product may expose users to chemicals including lead, known to the State of California to cause cancer (P65Warnings.ca.gov).
Usage Features:
- Control Panel: The chiller features a control panel with a visual readout for tub temperature, set point, and various buttons:
- Power Button: Turns the chiller on/off (2-second press).
- Mode Button: Switches between Fahrenheit and Celsius (5-second press).
- Setting Button: Changes temperature settings (1-second press to activate, then use arrows).
- Wi-Fi Activation Button: Engages Wi-Fi setup mode (5-second press).
- Up/Down Arrows: Adjust set temperature.
- Child Lock: Engaged by pressing both arrow buttons for 5 seconds.
- Indicators: Display system status (Cool/Heat), defrost status, compressor status, Wi-Fi status (solid for connected, blinking for setup, blank for disconnected), and ozone status (flashes when active).
- Wi-Fi / App Setup:
- Download and install the Tuya Smart application by scanning a QR code (also on the back of the chiller).
- Connect the device to a 2.4 GHz Wi-Fi network.
- Add the device in the app by selecting "Small Home Appliance" then "Thermostat (Wi-Fi)".
- Confirm network and password, then press and hold the "W" button on the chiller for 5 seconds until the Wi-Fi indicator flashes.
- The app allows remote control and scheduling (e.g., turning on the chiller 4 hours before a plunge and off 2 hours after).
- Startup Water Sanitation: Before initial use, the water requires a startup dose of sanitizer and oxidizer:
- Add 60cc (2 measuring cups) of Oxidizer, wait 15 minutes.
- Add 15cc (1/2 measuring cup) of Sanitizer, wait 15 minutes before use.
- Tub Cover: An inflatable, lockable cover with locking buckles is provided for safety and to maintain water temperature. Buckle combination locks can be set for added security.
- Ball Valve: A stainless steel ball valve controls water flow to and from the tub. It must be in the open (parallel) position when the chiller is operating to prevent damage.
- External Water Strainer: Prevents debris from entering the chiller. It consists of a Water Strainer Cover, Strainer O-Ring, and Inner Water Strainer.
- Water Filter Housing: Houses the Water Filter, comprising Upper and Lower Water Filter Housings. The filter removes debris from the water.
- Inflation Valve: Used to inflate the tub with the Double Action Air Pump.
Maintenance Features:
- Weekly Maintenance (approx. 15 minutes):
- Check Chemistry: Add Oxidizer (30cc for low volume, 60cc for high volume), wait 15 minutes. Use a test strip to check sanitizer levels (add 10cc if below "OK" range). Check Alkalinity, pH, and Calcium.
- Check External Water Strainer: Turn off chiller, close ball valve. Remove bottom red "Inlet" Chiller Hose and Water Strainer Cover. Clean Inner Water Strainer for debris. Check Strainer O-ring.
- Check Water Filter: Compare filter condition to a diagram. Replace if in "Replace" range, if flow reads less than 13.0 L/min, or if chiller noise increases. Empty water from Lower Water Filter Housing when changing.
- Routine Maintenance (every three months):
- Tub Maintenance: Disconnect from chiller, drain, wash with mild soap and water, rinse, air dry. Remove marks with a Magic Eraser. Check air pressure (refill to 10 PSI). Check for mildew buildup. Refill and perform initial sanitizer protocol.
- Chiller Descaling: Disconnect hoses, ensure ball valve is closed. Place hose ends in a 5-gallon bucket. Fill with 1:4 distilled white vinegar/water solution. Run chiller in heating mode at 104°F for 30 minutes. Drain, refill with clean water, run for another 30 minutes.
- Housing Maintenance: Wipe exterior with mild soap and water, wipe off residue. Inspect fan and remove debris.
- Takedown Instructions:
- Turn off chiller.
- Close ball valve.
- Drain the tub (multiple methods available, including disconnecting hoses, using the chiller to pump water out, or using a submersible sump pump).
- Disconnect hoses.
- Dry the tub thoroughly inside and out to prevent mildew.
- Deflate the tub using the Double Action Hand Pump (on "Deflate" side).
- Fold the tub for storage, secure with storage strap.
- Drain the chiller by unscrewing and emptying the Lower Water Filter Housing and External Water Strainer, then tipping the unit. Replace protective caps.
- Troubleshooting: The manual provides detailed troubleshooting steps for common issues such as hose leaks, water dripping from chiller/hoses, cloudy/foamy water, water not cooling, Wi-Fi connection problems, tub deflation, and various error codes (E1/FL/FU for air in circulation, E2/HH for high water temperature, E3/FU for low water flow, E4/AA, E5/AA, CH2 for temperature sensor failures).
