STRUCTURAL PREPARATION:
1. Literature dimensions are for reference only. Installation dimensions should be taken directly from the tub. An
Access panel of 18” x 18” minimum must be provided at the pump end of the whirlpool. Allowing sufficient clearance
to make final connections and for servicing the pump and power panel. Access may be through the wall or platform
apron at the end of the unit. In the case of sunken installations, access should be made through the ceiling below.
2. The bath should remain in its shipping carton/packaging until time of installation.
3. Install the drain fitting to the bath. THE DRAIN FITTING SOMETIMES WILL PROTRUDE BELOW THE BASE OF THE
TUB APPROXIMATELY 1 1/2". Clearance must be provided for the drain by cutting away the subfloor (where possible)
or by blocking below the tub as may be required.
WARNING: factory skirts do not allow for blocking up of the tub base. All blocking must be solid and provide uni-
form support to the tub base.
4. Tub must rest entirely on the base.
DO NOT SUPPORT THE WEIGHT OF THE TUB BY THE RIM. Where leveling is required, and to reduce vibration
noise, prepare a bed of wet mortar in area where tub is to be installed.
Carefully level unit, ensuring that uniform support is given to all areas of the base and that no portion of the lip is bearing weight.
DO NOT USE MORTAR IF YOUR TUB HAS THE DELUXE AIR SYSTEMS WITH JETS ON THE BOTTOM OF THE
BATH. The EZ level base will support the unit with Deluxe Air Systems.
5. Frame out under the tub rim as shown in one of the illustrations below. NOTE: Due to the variety of installations
possible, framing procedures other than those described may be required. Plumb in selected location using a level.
Level front to back and across on both sides. A ledge under the rim, or an apron without a ledge may be constructed
as required (see diagram 1A & 1B). Where installations will be against a wall, stud wall framing should run full length
to the floor (see diagram 1C or 1D). Install tub firmly against sheathing as indicated with blocking below rim to pre-
vent deflection or movement of tub. To prevent a rocking movement of tub after installation, it is important to have
rim in contact, but NOT supported by blocking material.
When placing the tub on a platform or cut out (see diagram 1A), the opening should be 2" smaller than the specified
rim dimensions. Extreme care must be taken in this type of installation to ensure the tub will come to rest entirely on
the base.
IF YOU HAVE PURCHASED A WHRILPOOL WITH AN INSTALLED TILE FLANGE, PROCEED AS FOLLOWS
CAUTION: THE TILE FLANGE DOES NOT SUPPORT THE TUB! A ledger board
must be provided under the bath rim as indicated in the installation instructions.
Take care to ensure the tub is not hanging from the ledger boards, as this will void your warranty.
PRE DRILL THE FLANGE and use nails or screws to secure the flange into the studs around the bath. Oversize the
holes slightly to insure fastener does not damage tub flange.
Install water resistant drywall against the tile flange and 1/8"-1" above the top of the whirlpool deck. Install the tile or
other finishing materials. Apply a second bead of silicone sealant between the first course of tile and the bath deck.
• All dimensions should be taken from tub on site. Specifications subject to change without notice. Specifications and
installations vary based on model.
NOTE: Before tub is used, the whirlpool system should be cleaned and disinfected.
For proper procedure, please see the Maintenance section of this manual page 12.
