A series of long deep pockets arranged side-by-side
form the configuration of each bag. The ultra fine fibers
used in the makeup of the filtering media offer to trap
the contaminant.
The fourth section is employed in the ATS unit for odor
control. Panels, filled with activated carbon granules,
are arranged in a vee bank configuration to provide
adequate surface area. The surface of each granule is
extremely porous and absorbs materials that are in a
gaseous or vaporized state that cannot be removed by
the particulate filters. Using the carbon filters without the
pre-filtration by the bag filters is not recommended.
When the panels have become saturated or fully loaded
they may be replaced with new or reactivated carbon.
The fifth section, the blower/motor section, has been
rated to handle the air movement requirements for the
systems and the adjoining ducting.
When the fire suppression system has been specified to
be factory furnished it consists of strategically located
chemical spray nozzles located in the impinger and
electronic air cleaner modules. The fire suppression
chemical is stored in a cylinder housed in a
weatherproof enclosure mounted on one side of the
blower module. An electrical detection device, mounted
downstream from the impinger module in the electronic
air cleaner module, activates the system by sending a
signal to a control head discharging the chemical
cylinder.
In addition to the electrical detection device, a remotely
located pull station is provided for mechanical activation
of the system manually.
Depending on the installation and any local, or other
governing requirements, the ATS unit fire suppression
system may be tied-in with other fire suppression
devices. When the fire suppression system is activated,
the unit electrical input power is disconnected to the
ATS unit blower and the high voltage required for the
electric air cleaner is disconnected. After the fire
suppression system has been activated, the
authorized fire suppression contractor must put it
back into service. For a system supplied, with the ATS
unit, refer to Figure 7.
2. Initial Start-up
Prior to equipment start-up, the fire extinguishing
system employed in the ATS unit (and possibly
adjoining equipment) must be inspected by properly
trained and qualified personnel. This includes all
actuation components including remote manual pull
stations, mechanical or electrical devices, detectors,
fire-actuated dampers, etc. These items shall be
checked for proper operation during the inspection in
accordance with the manufactures listed procedures. In
addition to these requirements, the specific inspection
requirements of the applicable NFPA standard shall
also be followed. If required, certificates of inspection
shall be forwarded to the authority having jurisdiction.
For a fire suppression system supplied with the ATS
unit refer to Figure 7.
A. Inspect the inside of the adjoining ductwork and
Trion cabinet to be sure it is clean and free of any
debris or construction materials. Especially note the
opening in the drain basin for any restrictions. The
ducting, where secured to the cabinet collars,
should be sealed watertight with either gasketing or
caulking.
B. Inspect the ionizing-collecting cells to see that all of
the ionizing blades are intact and that no large
pieces of foreign material are lodged between the
plates. Also verify that the cells are properly
installed in the cabinet with the spiked ionizing
blades located on the air entering side (Follow the
air flow directional arrows).
C. Check the high voltage leads to see that they are
connected to the proper terminals, both at the
ionizing-collecting cells and inside the power pack.
Refer to Figures 6.
D. Be sure that the drain lines from the drain basins
are completely connected and properly terminated.
A trap or seal of some type should be incorporated
in the line to prevent air bypass.
E. Check the water supply line to be sure water is
available and that the strainer, back flow preventer
(by others) and detergent system are properly
installed and connected. Refer to piping diagram
Figure 5.
F. Be sure that electrical power is available, that the
wiring is completed, and that the system blower is
ready to energize. Refer to field wiring diagram
Figure 6.
G. Be sure that all access doors are closed.
H. Close the system electrical supply switches, making
power available to the control and blower motor
starter. Check to verify blower rotation is as shown
on the rotation indicator arrow.
I. Turn the “ON-OFF” selector switch to the control
“ON”. The blower should run (if installed) and the
power supply(s) should be energized. Electrical arc-
over within the ionizing-collecting cells may occur. It
is a normal occurrence caused by accumulation
dust from constructions or other sources in the
cell(s) and should soon subside. If the arc-over in
continuous and does not subside, recheck the
routing of the high voltage leads between the power
supply(s) and the cell(s). Refer to field wiring
diagram Figure 6. The ionizer lead must be
connected to the ionizer and the connector lead to
the collector. If arc-over still occurs, or difficulty
