Concrete Foundation Pad
Installation
A concrete foundation and pad may be constructed to
elevate the machines. Care must be exercised in the
design of the foundation pad due to the force exerted
by the machine during extract. This concrete base
(recommended not to exceed 8 inches [20.32 cm])
must be poured, reinforced with rebar and tied to the
existing 12 inch (30.48 cm) minimum floor. Refer to
Figure 5 and Table 2.
IMPORTANT: Do NOT install a pad on top of the
existing floor. The foundation and pad must be
constructed and tied together as one piece.
If the existing floor is not reinforced concrete at least
12 inches (305 mm) thick over a solid foundation, the
following steps must be performed (refer to Figure 5):
1. Cut a hole larger on all sides than the machine
base through the existing floor. The foundation
should extend a minimum of 9 inches (229 mm)
for UW35 models or 12 inches (305 mm) for
UW60 - 150 models out from the machine on all
sides.
2. Excavate to a depth of 18 inches (457 mm) from
the top of the existing floor.
3. Produce a PYRAMID-SHAPED hole by
excavating the bottom of the hole to a width 6
inches wider on each side than the width of the
top of the hole.
4. If installing a foundation and pad, prepare a form
for the above-ground portion of the foundation.
Verify that the top of the foundation is level. The
height of the foundation pad must not exceed 8
inches (203 mm) above the existing floor.
5. Refill with compacted fill dirt, making sure to
allow for correct concrete thickness.
6. Wet the hole around the cement foundation well
and brush the exposed foundation with cement
grout.
7. Completely fill with a minimum of 12 inches
(305 mm) up to the existing foundation level plus
any added level for the desired elevated pad. The
concrete must be poured so that the entire
foundation and pad cures as one piece.
8. For new foundations only a bolt-locator fixture
or a rebar frame is available and a preferred
option. Embed the mounting bolts or rebar frame
as the concrete is poured. Ensure that the bolt
threads extend 2 inches (51 mm) for UW35 - 125
models and 3 inches (76 mm) for UW150 models
above floor level.
9. Allow concrete to dry.
10. Proceed to Machine Mounting and Grouting
section.
NOTE: If the washer-extractor installation will
include the Premium Wet Clean Module, the
elevated base must be designed to accommodate the
additional depth of 24 inches (60.96 cm).
