II. INSTALLATION
Unit Placement
CAUTION
In order to avoid injury, take proper precaution when lift
ing heavy objects.
See
Unit Dimensions
on page 4 for sizing mounting slab,
platforms or supports. Refer to figure 4 for mandatory
installation clearance requirements.
POSITIONING CONSIDERATIONS
Consider the following when positioning the unit:
D
Some localities are adopting sound ordinances based
on the unit sound level registered from the adjacent
property, not from the installation property. Install the
unit as far as possible from the property line.
D
When possible, do not install the unit directly outside
a window. Glass has a very high level of sound trans
mission. For proper placement of unit in relation to a
window see figure 5, detail A.
PLACING UNIT ON SLAB
When installing unit at grade level, the top of the slab
should be high enough above grade so that water from
higher ground will not collect around the unit. The slab
should have a slope tolerance as described in figure 5, de
tail B.
NOTE - If necessary for stability, anchor unit to slab as de
scribed in
figure 5, detail D.
ELEVATING THE UNIT
Units are outfitted with elongated support feet as illustrated
in figure 5, detail C.
If additional elevation is necessary, raise the unit by ex
tending the height of the unit support feet. Use a 2-inch
(50.8mm) Schedule 40 female threaded adapter to raise
the height of the unit.
The specified coupling will fit snugly into the recessed por
tion of the feet. Use additional 2-inch (50.8mm) Schedule
40 male threaded adaptors which can be threaded into the
female threaded adaptors to make additional adjustments
to the level of the unit.
NOTE - Keep the height of extenders short enough to en
sure a sturdy installation. If it is necessary to extend the
height further than what is stable, consider a different type
of field-fabricated framework that is sturdy enough for
greater heights.
