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]) (above existing floor) must be poured, reinforced with rebar and tied to the existing 6 inch (153 mm) (for 35 and 60 2-speed, L-speed and M-speed models) or 12 inch (305 mm) (for all other models) minimum floor. Refer to Figure 9 and Table 3.

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 6 inch (153 mm) (for 35 and 60 2-speed, L-speed and M-speed models) or 12 inch (305 mm) (for all other models) thick over a solid foundation, the following steps must be performed (refer to Figure 9):

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 35 models or 12 inches (305 mm) for 60 - 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-SHAPEDhole 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.

Specifications and Dimensions

6.Wet the hole around the cement foundation well and brush the exposed foundation with cement grout.

7.Completely fill with a minimum of 6 inch (153 mm) (for 35 and 60 2-speed, L-speed and

M-speed models) or 12 inch (305 mm) (for all other models) of 3500 psi concrete 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 35 - 125 models and 3 inches (76 mm) for 150 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).
