Install supplied fan adapter ring appropriate for fan to be installed.
Use supplied 3/8” flange bolts to fasten to top of module. Four
filter units with top mount 10 & 15 hp fans do not require an
adapter ring.
Install fan to top of module as shown. Use supplied 3/8” flange
bolts to fasten to top of module.
For single module units (4 filters), orient fan so silencer installed in
next step faces desired direction.
For two and three module units (8 & 12 filters), fan orientation like
shown in Fig A.7 allows silencer to be supported on top of adjacent
module.

L17587-34, L17587-35, L17587-36 & L17587-37 units require
two fans and two silencers to be installed as shown. If desired,
fans can be rotated in 30° increments but silencers will need to
be supported with installer supplied brackets when the silencer
overhangs the unit. For wiring details, see special dual fan
thermal override information on the wire diagrams at the back
of this manual.
