Troubleshooting guide

multiple module solenoid valve enclosures with heaters
are installed, daisy chain the wiring so that each heater
will have 100/115/VAC, 50/60 Hz at all times. Make
certain enough current is available to supply all heaters.
Example: If three solenoid valve enclosures are
supplied with cartridge heaters, make certain the
voltage supply can deliver 3 amps (1 amp per heater).
4.5 COMPRESSED AIR CONNECTION
Clean, dry, 90-110 PSIG (6.2-7.6 BAR) compressed air
is required for the pulse cleaning system to function
properly. Compressed air consumption is noted on the
UAS sales drawing. A shut-off valve, pressure regulator
and pressure gauge should be installed close to the
Supra-Blast unit. UAS recommends dedicated oil and
water removal filters be used to ensure clean, dry air is
delivered to the pulse system. Contact your local DUST-
HOG representative for information about UAS’s
Pneumatic Valve Assembly. Refer to Figure 15 for
recommended compressed air piping and Table 1 below
for proper compressed air line sizing.
4.6 ASSEMBLY OF OPTIONAL EQUIPMENT
BLOWER PACKAGE INSTALLATION
If a top-mount blower package was ordered, read the
manufacturer’s Installation and Operation Manual
completely before installing the blower. The blower
Installation and Operation Manual is attached to the
fan package. Perform all pre-installation checks prior
to installing the blower.
Remove the clean air plenum cover plate on top of the
filter module and save the mounting hardware. Ensure
ribbon gasket remains on the unit. Lift blower package
using safe, suitable means and position blower base
holes over filter module holes with blower discharge
pointing in the desired direction. Secure with bolt/
washer assemblies previously removed. Top-mount
blower packages include a blower outlet damper. Install
blower damper to outlet of blower assembly with
hardware provided.
If the blower package is a ground-mount blower, read
the manufacturer’s Installation and Operation Manual
completely before installing the blower. The blower
Installation and Operation Manual is attached to the fan
package. Perform all pre-installation checks prior to
installing the blower.
Outlet duckwork from the Supra-Blast unit to the blower
package can be connected to either the top or bottom
clean air section access panel(s). It is recommended
industry practice to provide vibration isolation between
the blower inlet and the dust collector outlet ducting.
DUCT SILENCER INSTALLATION
A duct-type (in-line) silencer is designed to bolt directly
to the blower outlet damper flange. Make certain there
is adequate room for the silencer in the discharge
direction. Provide at least 24" (61 cm) of unobstructed
space at the end of the silencer discharge. The air
discharge should be directed into an open area, free of
obstructions and with consideration for personnel safety.
!
CAUTION
Do not allow water and/or oil from the compressed air
system into the compressed air manifold reservoir. To
ensure a clean, dry air supply, especially when the unit
is installed outdoors, a water filter with automatic drain
(or a condensate trap with automatic drain) and a
coalescing filter should be installed (refer to Figure 15).

!
CAUTION
Using Table 1, select the proper diameter compressed
air line pipe to supply your dust collector. The final
connection size is a female 1" NPT fitting on each
module.
!
CAUTION
Purge the compressed air line to remove any debris
prior to making the final connection to the Supra-Blast
compressed air manifold(s). Apply pipe fitting sealant
on all compressed air supply piping fittings and
connections.
!
CAUTION
Anchor dust collector to concrete pad prior to installing
blower assembly. Make certain all hardware is
properly tightened.
!
CAUTION
If blower package has a 20 HP (15 kW) motor or
larger, ensure the blower support legs are installed
beneath the clean air plenum of the module to which
the blower will be mounted.
