Plenum Silencer

Plenum silencers are available for the blower/motor

assemblies. The plenum silencers are designed to

be mounted on the side of the TBV in line with

the selected blower/motor assembly. The plenum

silencers are equipped with an exhaust damper

for flow control, making it unnecessary to select a

separate damper assembly for the selected blower/

motor assembly. It is important to note that for

the TBV plenum models, only TWO (2) plenum

silencer mounting configurations will work without

interfering with roof opening procedures. For the

TBV insertable models, only ONE (1) possible

plenum silencer mounting configuration will work.

Although the plenum silencer primarily reduces

noise levels, it is also equipped with a built-in

exhaust damper. The plenum silencer mounting

configuration varies between the TBV plenum and

insertable models. For the TBV plenum model, there

are two possible mounting configurations. For the

TBV insertable model, there is only ONE possible

mounting configuration. The blower/motor plenum

silencers are shipped loose and must be assembled

and installed concurrently with the blower/motor

assembly. Mount the plenum silencer to the side of

the cabinet by drilling holes into the cabinet using

the existing holes in the silencer adapter mounting

plate as a guide. Fasten down using the 1/4-in

thread cutting screws provided. Refer to the below

illustration and the installation drawing shipped

with the plenum silencer instructions.
