Back and Side PSP (Perforated Supply Plenum) Installation
1. Locate the assembly and unpack it from the crate, being very careful not to dent or scratch the
outer surface. NOTE: Report any damage to the delivering freight carrier and file a claim if
appropriate.
2. Upon completion of the hood install, install the back PSP first. Then if applicable, install the side
PSPs.
3. If the supply risers are to be field cut, cut the risers in as desired.
4. Locate the ceiling joists which will support the assembly. If using Unistrut®, then securely attach
to the ceiling joist.
5. Use 1/2” threaded rod to hang the PSP. Install the threaded rod and angle that will be used to
hang the assembly from the ceiling joists. Drill 9/16” holes in the angle if not using Unistrut®. Be
sure to line up with the angle mounting brackets on the PSP.
6. Peel the protective plastic coating on the hood down below where the bottom edge of the PSP
will rest against the hood, so it does not remain behind the PSP.
7. Move the PSP into position as indicated by the project submittal drawings; lining up the top edge
of the PSP with the top edge of the hood. Remove the protective coating from the back of the
PSP. See Figure 10.
8. Install the threaded rod into the PSP hanging angles and use heavy duty nuts to secure the
connection. Adjust tension on hanging rods to position PSP so it fits flush with the hood. NOTE:
Do not apply too much tension; otherwise, a gap between the PSP and Hood will be
created at the bottom.
9. Install additional PSPs, if applicable, in the same manner.
10. Where applicable, use sheet metal screws to secure the PSP attaching bracket on top of side
PSPs to front PSP. See Figure 11.
11. Caulk the seams between the hood(s) and each PSP assembly, as well as between adjacent
PSP assemblies (if applicable) after the hood(s) and hood accessories have been installed. An
isometric view of the hood assembly for a model PSPFBSS is shown in Figure 12.
