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 inches 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 inches 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 the following figure).
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
and
), the front grilles may be removed for
access to the mounting holes.
