Before You Begin

CAUTION: Risk of product damage. Do not lift the bath with airjets by the piping or blower
motor, or use the piping or blower motor for structural support of the bath.
For All Installations
We recommend this bath with airjets for drop-in or island installation, depending on the purchased
model.
Inspect the bath for damage before you begin installation.
You must install this bath to an adequately supported, level subfloor.
Please read these instructions carefully to familiarize yourself with the required tools, material, and
installation sequences. Follow the sections that pertain to your particular installation. This will help
you avoid costly mistakes. In addition to installation instructions, read all operating and safety
instructions.
The variety of installations possible with this bath may require framing procedures other than those
described in this manual.
Both concrete and wood frame construction techniques are discussed in this manual.
Confirm adequate mounting and connection space for the faucet specified for your installation.
For Remote Blower Locations Only
IMPORTANT! It is not necessary that the blower motor be relocated. The option is provided for the case
that a particular installation makes this effort practical.
For your convenience or accessibility, the blower motor and check valve can be mounted in a
remote location. Choose a space as close to the bath as possible to maximize bath performance. Plan
and prepare for the relocation. Pay attention to the following requirements and recommendations:
• The blower motor must be located within 15' (4.6 m) of rigid piping from the bath air harness. This
limitation is for total pipe length and applies to any direction changes and elbows. There can be no
more than six changes of direction. There should be as few direction changes as possible.
• The blower motor must be mounted horizontally at least 2" (5 cm) above the floor. Do not mount
the blower motor with the blower motor discharge pointing up.
• The check valve should be relocated with the blower motor. At the new location, the check valve
must be no lower than 24" (61 cm) below the rim of the bath. The check valve must be within 12"
(30.5 cm) of the blower motor. The check valve must be oriented vertically with the flow arrow
pointing up.
• 1-1/2" PVC or equivalent rigid piping should be used.
• The piping installation must meet the requirements of local plumbing or building codes. Ensure that
the installation does not reduce the fire rating of any walls. Piping must be supported at intervals
along the length in accordance with local codes.
• Use PVC unions or other means of making the installation maintainable.
• The blower motor must have adequate ventilation. Do not install the blower motor closer than 1"
(2.5 cm) from the wall or other objects. Provide a ventilation space of at least 15 cubic feet (.4 cubic
meters) for cooling.
• Ensure that the blower motor location is clean and free of dust or debris.
• If appropriate, install an additional access panel for blower motor maintenance.
• The 18 AWG (American Wire Gauge) minimum power cable to the blower motor must meet the
requirements of the applicable electrical or building codes. Ensure that the installation does not
reduce the fire rating of any walls.
• The power cord must be supported at intervals along the length in accordance with local codes.
Power cords may not rest on surfaces or floors that are subject to flooding.
• All material needed for the relocation must be supplied by the installer.
