Framing Requirements
Due to individual site variations, exact
guidelines for every situation cannot be
supplied. The recommended framing
and dimensional requirements shown
are for a typical application and may
vary, depending on site requirements.
The dimensions shown in Figures 1a and
1b are from the surfaces where the unit
will be attached. This surface can be
bare studding, dry wall or other suitable
underlayment material. It is important
that the floor and all framing be square
and level. Framing should be done
using accepted materials and con-
struction techniques, in accordance
with all applicable codes.
An optional unit cap is available for
selected tub/shower models, which will
require the construction of a header for
proper unit installation. The header is
only required for units using a cap.
Optional Unit Cap Installation
An individual set of installation guide-
lines are included in the optional unit
cap package. The unit cap CANNOT
be properly installed after the unit has
been secured in the framed area.
Refer to, and follow the instructions
packaged with the cap before
continuing.
NOTE: It is advisable to have the unit on
site during the early stages of framing.
NOTE: Any pre-constructed wall may
require modifications or additional
framing members to allow for pipes or
fittings which protrude from the unit on
whirlpool equipped models, for proper
unit installation.
NOTE: A pump access is MANDATORY
on all whirlpool equipped modules.
Additional access areas may be
necessary to comply with code require-
ments. (Figure 1a and 1b)
