4. Installation (Setup)
Professional installation by a licensed plumber and electrician is highly recommended to ensure proper function and compliance with all local codes.
Pre-Installation Checklist
- Verify product dimensions and rough-in requirements against your installation space.
- Ensure adequate structural support for the bathtub's weight when filled with water and occupant(s).
- Confirm availability of hot and cold water supply lines at the installation site.
- Confirm electrical supply (120V AC, dedicated GFCI circuit) for the heated jet massage system.
- Acquire the necessary Universal Rotary/Cable Drain Kit (sold separately).
Steps for Drop-In Installation
- Prepare the Alcove: Construct a sturdy alcove or deck structure that precisely matches the bathtub's dimensions, allowing for the 3-tile flange. Ensure the opening is accurate for a snug fit.
- Leveling: Carefully place the bathtub into the prepared opening. Use shims if necessary to ensure the tub is perfectly level in all directions.
- Drain Connection: Install the Universal Rotary/Cable Drain Kit according to its manufacturer's instructions. Connect the drain to the household plumbing system, ensuring all connections are watertight.
- Water Supply Connection: Connect hot and cold water supply lines to the bathtub's faucet (faucet not included). Use appropriate plumbing fittings and sealants to prevent leaks.
- Electrical Connection: A qualified electrician must connect the bathtub's electrical system to a dedicated 120V AC, GFCI-protected circuit. Refer to the electrical diagram provided with the tub for specific wiring instructions.
- Water Test: Fill the bathtub with water to above the jets and operate the jets and heater to check for leaks and proper functionality. Inspect all plumbing and electrical connections thoroughly.
- Final Sealing: Once satisfied with the installation and leak-free operation, apply a waterproof sealant around the perimeter of the bathtub where it meets the surrounding surfaces (e.g., tile, deck).
5. Operation
Follow these steps to operate your Jacuzzi bathtub safely and effectively.
Filling the Bathtub
