Extenders (Small Base Units)
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.
The inside diameter of the 4" (101.6mm) piping is
approximately 0.25" (6.35mm) greater than the
pre−installed feet on the unit. Devise a shim that will take up
the space and hold the extenders onto the feet during this
procedure. Small strips of 0.125" (3.175mm) thick
adhesive foam may be used. One or two small 1"
(25.4mm) square strips should be adequate to hold the
extender in place.
ELEVATING THE UNIT (LARGER−BASE UNITS)
Unlike the small−base units which use round support feet,
the larger−base units are outfitted with elongated support
feet as illustrated in figure 11 which uses a similar method
for elevating the unit.
If additional elevation is necessary, raise the unit by
extending the length of the unit support feet. This may be
achieved by using a 2" SCH 40 female threaded adapter.
The specified coupling will fit snuggly into the recessed
portion of the feet. Use additional 2" SCH 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.

STABILIZING UNIT ON UNEVEN SURFACES
To help stabilize an outdoor unit, some installations may
require strapping the unit to the pad using brackets and
anchors commonly available in the marketplace.
With unit positioned at installation site, remove two side
louvered panels to expose the unit base pan. Install the
brackets as illustrated in figure 12 using conventional
practices; replace the panels after installation is complete.
