4.4 ASSEMBLY OF OPTIONAL EQUIPMENT
FAN PACKAGE INSTALLATION
If a top-mount fan was ordered, remove the clean air
plenum cover plate and save the mounting hardware.
Ensure Teflon
®
ribbon gasket remains on the unit. Lift
fan package using safe, suitable means and position fan
base holes over cabinet holes with fan discharge
pointing in the desired direction. Secure with bolt/
washer assemblies previously removed.
If the fan package is a ground-mount fan, follow
manufacturer’s recommendation for installation. The
installation manual is attached to the fan package.
Outlet ductwork from the Supra-Pulse unit to the fan can
be connected to either the top or bottom access panel.
Panels which are not used as clean air discharge
connection points will serve as inspection ports.
The bottom access panel and its gasket are shipped
loose with installation hardware. If the bottom access is
not to be used for discharge ductwork, attach the panel
to the bottom opening using the hardware provided.
DUCT SILENCER INSTALLATION
A duct-type silencer is designed to bolt directly to the
fan outlet damper flange. Make certain there is
adequate room for the silencer in the discharge direction
and provide at least 24" of unobstructed space at the
discharge end of the silencer. The air discharge should
be directed into an open area free of obstructions and
with consideration for personnel safety.
The silencer will require separate support. Apply silicone
around the bolt holes of the connecting flanges, lift the
silencer into position and secure with the hardware
provided. Install permanent supports (not supplied by
UAS) and tighten all hardware before removing the
lifting device.
ROTARY AIR LOCK INSTALLATION
If a rotary air lock was ordered with the unit, the hopper
discharge will have an adapter already bolted to it.
Ensure that the bolts connecting the adapter to the
hopper discharge are securely tightened.
Remove all packing from the rotary air lock and
determine its appropriate position. Keep in mind
required clearances, electrical connections and
maintenance requirements. Apply sealant to the flange
of the rotary air lock and fasten to the adapter using 3/8"
bolts, nuts, washer and lock washers.
All electrical connections should be made by a qualified
electrician according to all applicable codes. Refer to the
nameplate and/or documentation attached to the rotary
air lock for voltage, amperage, cycle and proper wiring.
ABRASIVE RESISTANT INLET INSTALLATION
The abrasive resistant inlet is designed to use the front
access(es) of the Supra-Pulse modules as the inlet area
to the unit. There are three styles available: the single,
dual or triple module abrasive resistant inlet. Each is
designed to fit over the appropriate number of front
accesses to serve as a single inlet point for one to three
modules (see Figure 7).
Remove the front access plate(s) located above the
filter access doors. Save the hardware; this will be used
to attach the abrasive resistant inlet. Remove any
remaining gasket material from around the perimeter of
the opening.
Apply a 1/4" bead of sealant around the perimeter of the
access opening. Clean out if required for maintenance. If
the bottom plate is removed, carefully remove the ribbon
of Teflon sealant and reuse after cleaning the gasket
surfaces. The bottom plate on the abrasive inlet will
serve as an inspection plate. Clean out if required for
maintenance. If the bottom plate is removed, carefully
remove the ribbon of Teflon sealant and reuse after
cleaning the gasket surfaces.
!
CAUTION
Disconnect all power to the rotary air lock before
servicing. There are moving parts on the rotary air
lock. Do not allow any object to be placed in or near
the rotary air lock during operation.
!
CAUTION
Do NOT use the fan damper flange to support the
silencer.
