Seismic Floor Stand Attachment Plates
Attachment plates are provided with seismic floor stands to secure the A/C unit to the stand. Refer to the floor
stand assembly drawing provided with your unit. Once the A/C unit is in place on top of the floor stand, mount
the attachment plates to the stand. The plates for low seismic floor stands are to be attached with 1/4” sheet
metal screws. Drill the sheet metal screws into the floor stand through the lower holes in the attachment plate
and into the base of the A/C unit through the upper holes in the plate. Ensure all the screws are tightened.
Take care not to strip the threads.
For high seismic stands, attach the plates to the stand with 1/2” bolts as shown in the floor stand assembly
drawing. Drill holes for the fasteners into the base of the A/C cabinet through the upper holes in the plate. Secure
the A/C unit to the floor stand (fasteners to be customer furnished). Ensure all the fasteners are tightened.

Plenum Box
If an optional plenum box (plenum extension box
or 2 - 3 way air distribution plenum box) is
selected it is typically shipped loose. To install a
plenum box, first
apply a strip of sealing foam gasketing around the top
flange of the A/C unit or run a bead of silicone
sealant. Place the plenum assembly on top of the unit
(see Figure 12). Attach the plenum with the self-
tapping screws provided. Holes are pre-drilled in the
plenum box. If mounting a 2 - 3 way air discharge
plenum box (shown in Figures 8 and 10), the front
grilles may be removed for access to the mounting
holes.
