3.3.3 Pouring the Concrete Pad (B5 Cabinet Only)
Due to the extreme weight of the B5 cabinet, a concrete pad may be necessary to support the weight of the
unit. The pad should be poured in advance and be able to support the weight of the unit (1370 lbs/621 kg).
3.3.4 Make Openings in the Wall
Make openings for supply and return air and cable and bolt holes in the installation wall as shown in Figures
4-5. Refer to the tables below the drawings for dimensions. All dimensions are accurate to 1/16 in (2 mm).
Note: The 28V1B5 requires three openings (Figure 5).
Note: The template printed on the shipping carton can be used to create wall cuts.
