This article provides a detailed overview of the installation process, technical specifications, and critical safety considerations for the 2460/2461 whirlpool tub model. Based on the official installation and technical documentation provided by the manufacturer, this guide is intended for licensed professionals, DIY enthusiasts, and consumers seeking to understand the installation requirements and operational parameters of this product.
Overview of the American Standard Whirlpool Tub
The 2460/2461 whirlpool tub is a fully assembled unit that includes the pump, motor, and system piping. It is designed for recessed installation and requires careful planning and execution to ensure both structural integrity and functional performance. The unit must be installed in compliance with electrical, plumbing, and construction standards to meet warranty and safety requirements.
The tub measures 60 x 32 x 17-3/4 inches (1524 x 813 x 451 mm) and has a dry weight of 142 lbs (64 kg). When filled with water, the total weight increases to 559 lbs (254 kg). It holds up to 50 gallons (190 liters) of water before overflowing, with a minimum operating volume of 39 gallons (148 liters) required for whirlpool functionality. These specifications are essential for planning the structural support and load-bearing capacity of the installation site.
Required and Optional Components
Several components are required for the installation of the whirlpool tub, while others are optional and must be sourced separately.
Required Components (Not Included)
- Drain: 1583.470 (must be obtained through the American Standard distributor)
- Bath Filler: Must be ordered separately
Optional Components (Not Included)
- Safe-T-Heater 9075.120: Provides additional safety features and must be installed via a dedicated GFCI circuit
It is important to note that the whirlpool system is shipped fully assembled with its pump, motor, and piping, but all fixtures and fittings must be procured separately. Installers must ensure that the correct components are ordered and installed in accordance with the manufacturer's specifications.
Electrical Installation Requirements
Electrical installation is a critical component of the whirlpool tub setup. The unit requires a dedicated electrical circuit and must be installed by a licensed electrician to ensure compliance with safety standards.
Circuit Requirements
- The whirlpool must be connected to a 120 vac, 15 amp dedicated circuit.
- The circuit must be hard-wired from the electrical power supply panel and must include a three-wire system: grounded neutral wire and an earth ground wire.
- If the Safe-T-Heater is added, it must be connected to a separate 15 amp maximum GFCI circuit.
Electrical Safety
- The unit must be grounded.
- Do not modify the whirlpool system or remove the pump from its factory mounting. Such actions may affect performance and void the warranty.
- Do not lift the whirlpool by the pump, motor, or piping system at any time.
The manufacturer emphasizes that electrical connections must be handled by a qualified professional to ensure safety and code compliance. The installation should be designed to allow access for future servicing of the pump and control systems.
Plumbing and Drainage Considerations
The whirlpool tub requires specific plumbing arrangements to ensure proper drainage and prevent water damage. The drain connection is a 1-1/2" NPT thread, and the installation must include a floor cutout of 9" x 12" (229 x 305 mm) for the pump. Additionally, a rough floor to tailpiece dimension of 4-5/8" (117 mm) is required for proper alignment and sealing.
Drain and Water Flow
- The tub has a minimum operating volume of 39 gallons (148 liters) for whirlpool functionality.
- The bathing well at the sump measures 41 x 20 inches (1041 x 508 mm), while the bathing well at the rim is 54 x 26 inches (1372 x 660 mm).
- The water depth to overflow is 14 inches (336 mm).
These measurements are essential for planning the water capacity and ensuring that the installation allows for adequate water flow and drainage.
Framing and Structural Installation
The whirlpool tub must be installed in a recessed configuration, positioned above the floor line. This requires precise framing and support to ensure the tub is level and secure.
Framing Requirements
- The tub is supported from the apron and the rear tiling flange.
- No support is required under the sump.
- A leveling support stringer should be used to maintain stability.
- Ensure the tub is level front to back and side to side, and use shims as necessary.
- Check the drain clearance hole in the subfloor for proper alignment.
Securing the Tub
- For installations involving wood studs, use roofing nails immediately above the flange of the tub.
- For steel studs, use drywall screws with flat washers.
The installation must also include an access opening of at least 12" x 24" (305 x 610 mm) to allow for servicing of the pump and control systems. This is a requirement for warranty compliance.
Safety Precautions and Warranty Compliance
Several safety precautions must be followed to ensure the proper functioning and longevity of the whirlpool tub. These include:
General Safety Guidelines
- Do not make modifications to the whirlpool system or remove the pump from its factory mounting.
- Do not handle or move the whirlpool by the pump, motor, or piping system.
- Avoid damaging the tub during installation by using a drop cloth to protect finished surfaces.
- Do not lift the whirlpool by the piping harness at any time.
Warranty Considerations
- The warranty is void if the pump is removed from its factory mounting or if unauthorized modifications are made to the whirlpool system.
- The access opening for servicing is a warranty requirement and must be included in all installations.
The manufacturer recommends that all installations be carried out by a qualified professional to ensure compliance with warranty terms and safety standards.
Testing and Leak Detection
Before enclosing the tub with wallboard, tile, or other finishing materials, it is essential to water test the unit and check for leaks. This step helps identify any potential issues with the plumbing or installation.
Testing Procedure
- Fill the tub with water to the minimum operating level.
- Allow the water to sit for a period of time to check for leaks or water seepage.
- Ensure that all connections and joints are secure and free from damage.
If any leaks are detected, the installation must be reviewed and corrected before proceeding with final finishing work. This step is crucial for preventing water damage and ensuring the long-term functionality of the whirlpool system.
Electrical and Mechanical Specifications
The whirlpool system includes a 1.4 HPR pump operating at 7.5 amps and 120 volts. The safety heater, if included, operates at 12 amps and 120 volts. These specifications are essential for determining the electrical load and ensuring that the circuit can support the system without overloading.
Key Electrical and Mechanical Data
| Component | Specification |
|---|---|
| Pump System | 1.4 HPR, 7.5 AMPS, 120V |
| Safety Heater | 12 AMPS, 120V |
| Installed Size | 60 x 32 x 17-3/4 In. (1524 x 813 x 451mm) |
| Floor Loading | 41 Lbs./Sq. Ft. (200 Kgs./Sq.m) |
| Water Volume (Overflow) | 50 Gal. (190 L) |
| Minimum Operating Vol. | 39 Gal. (148 L) |
These specifications must be considered during the installation planning phase to ensure that the electrical and structural systems can support the whirlpool tub without risk of failure or damage.
Final Precautions and Maintenance
After installation, it is important to follow several precautions to ensure the continued performance and safety of the whirlpool system.
Post-Installation Precautions
- Avoid driving nails or screws near the tub to prevent damage.
- Ensure that tile or finished flooring is properly aligned with the tub apron to hold the tub in place.
- Regularly inspect the pump and motor for signs of wear or malfunction.
- Follow the manufacturer’s guidelines for cleaning and maintenance to extend the lifespan of the system.
