Unit Placement

CAUTION

In order to avoid injury, take proper precaution when
lifting heavy objects.

See 

Unit Dimensions

 on page 3 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:

Some localities are adopting sound ordinances based
on the unit’s sound level registered from the adjacent
property, not from the installation property. Install the
unit as far as possible from the property line.

When possible, do not install the unit directly outside
a window. Glass has a very high level of sound
transmission. For proper placement of unit in relation
to a window see the provided illustration in 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,
detail B.

NOTE  If necessary for stability, anchor unit to slab as
described 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
extending the height of the unit support feet. This may be
achieved by using a 2 inch (50.8mm) Schedule 40 female
threaded adapter.

The specified coupling will fit snuggly into the recessed
portion 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
ensure a sturdy installation. If it is necessary to extend
further, consider a different type of field−fabricated
framework that is sturdy enough for greater heights.
