Setup and Installation
Installation of the Americh Catalina 6642 Drop-In Whirlpool Tub requires professional expertise. It is strongly recommended that installation be performed by a licensed plumber and a qualified electrician to ensure compliance with all local building, plumbing, and electrical codes.
Pre-Installation Checks:
- Verify that the installation site can support the tub's weight (approximately 197.6 lbs empty, significantly more when filled with water and occupied).
- Ensure adequate access for plumbing and electrical connections.
- Confirm that the dimensions of the rough-in opening match the tub specifications (66 x 42 x 22 inches).

Installation Steps (Summary - Consult Professional for Details):
- Prepare the subfloor and framing for the drop-in installation.
- Position the tub into the prepared opening.
- Connect the drain and overflow assembly according to plumbing codes.
- Perform all necessary electrical connections for the whirlpool and AirBath II systems, ensuring proper grounding and GFCI protection.
- Fill the tub with water and test all functions (whirlpool jets, air jets, drain) for leaks and proper operation before sealing the perimeter.
- Seal the tub perimeter to the deck using a waterproof sealant.
Operating Instructions
Filling the Tub:
- Ensure the drain is closed.
- Fill the tub with water to a level at least 2 inches above the highest jet opening. Operating the whirlpool or air bath system without sufficient water can damage the pump or air blower.
Activating the Whirlpool System:
- Locate the whirlpool control button (typically a pneumatic button or electronic keypad).
- Press the button to activate the hydro-massage jets.
- Adjust the intensity or direction of the jets if your model includes these features.
- Press the button again to turn off the whirlpool system.
Activating the AirBath II System:
- Locate the AirBath II control button.
- Press the button to activate the perimeter-placed air jets, creating a gentle bubbling sensation.
- Some models may offer variable speed or pulse settings for the air blower.
- Press the button again to turn off the AirBath II system.
Draining the Tub:
- After use, open the drain to empty the tub.
- It is recommended to run the air system for a short period after draining to help dry the air channels and prevent stagnant water.
Maintenance
Cleaning the Tub Surface:
- Clean the acrylic surface regularly with a soft cloth or sponge and a non-abrasive, mild bathroom cleaner.
- Avoid using abrasive powders, scouring pads, or harsh chemical cleaners (e.g., acetone, paint thinner, strong acids/bases) as these can damage the glossy acrylic finish.
- Rinse thoroughly with clean water after cleaning.
System Cleaning (Whirlpool & AirBath II):
- Whirlpool System: Periodically fill the tub with warm water and add a small amount of low-foaming detergent or a specialized whirlpool cleaner. Run the whirlpool system for 10-15 minutes, then drain and rinse.
- AirBath II System: The AirBath II system is designed to self-purge. After draining the tub, run the air blower for a few minutes to clear any residual water from the air channels.
- Inspect jets and air ports regularly for blockages and clean as needed.
