I NSTALLATION
The BRAHM ™ Collector Plug and Play Series require some minor assembly.
A standard unit will come with an exhaust cover pre-installed.
A standard unit will come with electrical panel pre-installed.
In some instances, filters may be shipped separate from the unit, requiring installation on site.
See the 'BRAHM ™ Collector Accessories User Manual' for accessory assembly instructions.
General Installation Guidelines
Clean Air Industries BRAHM ™ Collectors are shipped via freight and generally arrive on a flat bed trailer or
box trailer. The units are typically palletized. Use a fork
lift truck driven by a qualified individual, to remove the unit
and other pallets from the truck. Occasionally, fork
extensions are helpful.
Once the unit is inside the facility, ready to be unpackaged,
please proceed cautiously. Banding straps, cardboard, and
plastic wrap must be removed.
BRAHM ™ Collectors are heavy and tend to be irregularly
weighted. The motor and the majority of the metal are
located on the motor / valve side of the unit. This can make
transporting the units hard to handle. Please see the "Unit
Weight" section for proper weights.
Unlike the regular BC Series, the BC Plug and Play Series
only come as a single module unit and comes standard with
36 ” stand.
There are (4) steel plate eyelets vertical on the top of unit or section. These are the lifting lugs, and
can be used for moving the unit around.
The unit needs to be placed on the stand. The 4 feet of the unit must be bolted to the stand to secure
the unit to the stand

W ARNINGS AND L ABELS
HIGH VOLTAGE: The voltage of the BRAHM ™ Collector is
dangerous once connected to a power supply. Incorrect
installation may cause damage to the equipment, serious
injury, or death. Consequently, it is essential to comply with
instructions in this manual, local and national safety rules, and
follow all safety procedures including proper lock out and tag
out procedures.
ELECTRICAL SHOCK HAZARD: The Variable Frequency
Drive (VFD) uses large capacitors which can hold a charge
long after the power has been disconnected from the unit. Do
not service the panel until the VFD has fully discharged.
GROUND CONNECTION: Proper grounding of the equipment
and electrical panel is essential. Do not attempt to operate the
equipment without electrically grounding the panel. The
connection to the earth ground must be proper and provide a
low impedance path to the earth to prevent hazardous
voltages from appearing on equipment.
COMPRESSED AIR: Compressed air is used in the operation of
this unit. Follow proper lock out / tag out procedures prior to
servicing the unit. This includes draining the compressed air
reservoir inside the unit. Failing to do so can lead to injury or hearing
loss. Look out – drain tank – do not service while pressurized.

S ETTING THE B RAHM ™ C OLLECTOR ON THE S TAND
NOTE: Ple ase see the "Moving the Brahm™ Collector" section prior to setting the unit
on the stand.
NOTE: The dust trays and hoppers may be attached to the unit before the unit has been
placed on the stand.
The Brahm™ Collector can easily be moved by
using a fork lift truck. Place the forks under the
unit. Be mindful not to damage the dust tray or
hopper mounting angles on the bottom of the unit.
Attach the lifting chains or cables to the forklift
“headache” bar. Attach the other end of the lifting
chains or cables to the lifting lugs. Keep in mind,
the motor side of the unit is heavier and forks may
need to be shifted toward this side.
Make sure not to scratch or damage the unit.
Place cardboard between the unit and the fork lift truck to prevent damage
When possible, lift and set the unit from the back side to reduce risk of damage to the filter and dual
compartment doors.
When setting the unit, be mindful of the bottom of the unit. Make sure the unit feet are placed inside
the stand corners to prevent damage to the stand. The feet of the unit should line up with the flanges
on the corners.
Lift both halves onto the stand. Once both halves are on the stand, they can be bolted together. Make
sure to bolt the halves together before bolting the unit to the stand. If bolted to the stand first, the unit
may leak where the two halves are joined together.
Once the unit is on the stand (and halves are bolted together where applicable), the unit can be
bolted to the stand. Attach the unit to the stand using 3/8"-16 x 1" bolts. These bolts should be placed
through the flanges on the top of the stand and into the weld nuts on unit's feet. Make sure the bolts
are secured with washers and lock washers to prevent loosening over time.

G ETTING S TARTED
After the unit has been installed at its final place and the electrical and compressed air line has been
connected, the unit needs to be tested to make sure that all the features run as intended. This step is usually done by Clean Air Industries installation team. Here is a quick guide to test the system and get familiar with the unit
• The first thing to do is to rotate the Power Disconnect to ON position to turn on the unit. Then,
press the green button to start the blower and red button to stop the blower. Refer to page 61
for more details.
• All Brahm Collectors are equipped with Smart Pulsing System. On auto mode, the unit will
automatically pulse to self-clean the filter. Refer to the Pulse Settings Section for more
details..
• All BC Plug and Play Units are equipped with Variable Frequency Drive. The unit will adjust
its motor speed automatically based on the condition of the filter. The speed can also be
adjusted manually from the VFD.
• (Optional) When Fire Suppression System is equipped, the unit will have louvers on the inlet
and exhaust side. During fire, the motors will stop and the louvers will automatically close to
contain and suppress the fire in the unit. There is a 20 s delay for the fire canisters between
each module to allow the louver to close and prevent voltage spike to trip the circuit breaker.
Remember, DO NOT rotate the Power Disconnect into OFF position as this will cut power off
and thus deactivate the Fire Suppression System. The BC Plug and Play is also equipped
with a backup fire tube detection system in case of loss of power, allowing the canister to still
actuate.
Important!!! On units with Fire Suppression System, the fire solenoid is in disconnected position when the unit leaves Clean Air Industries facility . This allows for the FSS to be tested onsite without actually actuating the fire canister. Check in the junction box to make sure that it is connected when the unit is
ready!

F IRE S UPPRESSION F UNCTIONS
The functions of the fire suppression system (FSS) are driven by the Smart Relay. Heat and smoke
sensors internal to the unit are used for fire detection, and the system can be activated manually
through the fire pull. The system behaves as follows:
If:
Then:
The Key Switch is turned OFF
The fire suppression system is deactivated
(Key will be retained)
The motor/VFD will shut down immediately, valve pulsing is shut down immediately, louver closes immediately, alarm/strobe will activate immediately, and the fire bottle is triggered after a 20 second delay. The motor/VFD will shut down immediately, valve pulsing is shut down immediately, louver closes immediately, alarm/strobe will activate immediately, and the fire bottle is triggered after a 20 second delay. The motor/VFD will shut down immediately, valve pulsing is shut down immediately, louver closes immediately, alarm/strobe will activate immediately, and the fire bottle will NOT be triggered.

FSS C OMPONENTS
Key Switch
NOTE: The system can only be deactivated while the power is off. The key switch will not function
once power to the panel has been turned on using the Disconnect.
The key switch is located on the front of the electrical door, and it is a retentive key switch. This
means while the system is turned off, the key cannot be removed. It is recommended that the key be
removed when the fire suppression system is active as a visual check. The fire suppression system
can only be deactivated when the power to the electrical disconnect is off. Once the power is on and
the key has activated the fire suppression system, the system will not turn off even if the key switch is
activated. The key switch is wired fail safe so that if the wires are removed or cut, the fire suppression
system is activated.
The fire suppression system can be deactivated using the key switch. When changing the filters in the
system per proper maintenance, dust can be dropper through cads and below the filter compartment.
This dust can then trigger the smoke sensors in the valve compartment. To prevent this, it is
recommended that the fire suppression be turned off using the key switch for several minutes upon
restarting the system after a filter change. After several minutes, the fire suppression can be
reactivated while the system is still running (it need not be restarted again). This process is only
necessary after filter changes, not on all startups.
If the key switch has been activated(FSS is deactivated) , the display will show “FSS OFF”

Fire Pull
The fire pull is used for the manual activation of the fire suppression
system. The fire pull will be mounted on the front of the electrical door. A
key is used to reset the fire pull once it has been activated, and a glass
tube can be inserted to detect an activation that has been reset.
To reset the fire pull, the power must be turned off before the fire pull has
been reset. The internal program of the Smart Relay latches shut
electronically, forcing the power to be cycled off and then on. If the fire pull
has been activated, the display will show “FPull” as shown in the picture
below.
NOTE: The fault must also be cleared on the HMI by pressing the “FSS
Reset ” button on the fire suppression screen.

Smoke Sensor
The smoke sensor is located on back wall of the valve
compartment next to the primary heat detector. It should
be visible on the wall opposite the compressed air
reservoir when being viewed from the access panel. It can
be tested by using a magnet to trip the relay inside. This is
done be rubbing the magnet over the area marked
“TEST”. Cans of smoke can be purchased as well for a
functional test.
The smoke sensor is set off by certain types of contaminants in the air found in smoke. If dust from the
filters is allowed to get into the valve compartment, this can also set off the smoke detector. Also if the
filters are misaligned, the smoke can bypass the filters and enter the valve compartment tripping the
sensor. When sensor is working properly, it will have two green flashing LEDs on the sensor head. When
the senor (smoke or heat) is tripped, both LEDs will turn red and stop flashing. If dirt or contaminant is
introduced to the sensor, it can build up and cause false trips. The sensor head must then be taken apart
and cleaned by blowing the contamination out with compressed air.
NOTE:
The heat sensor and smoke sensor use the same base. The bases are wired
identically with the exception that the normally open signal is routed to a
different location in the electrical box.
To reset the smoke sensor, the power must be turned off and the unit and sensor blown out with
compressed air to clean out any remaining smoke dust. The internal program of the controller latches
shut electronically, forcing the power to be cycled off and then on. If the smoke sensor has been
activated, the display will show “Smoke” as shown in the picture below.

Primary Heat Sensor
The primary heat sensor is located on back wall of the valve compartment next to the smoke sensor. It
should be visible on the wall opposite the compressed air reservoir when being viewed from the access panel. For indoor units, the sensor is activated if the temperature reaches 135 o F. For outdoor units, the sensor is activated if the temperature reaches 190 o F. It can be tested using a heat gun directed towards
the sensor
To reset the primary heat sensor, the power must be turned off and the sensor must be allowed to cool.
The internal program of the controller latches shut electronically, forcing the power to be cycled off and
then on. If the primary heat has been activate d, the display will show “Heat1” as shown in the picture
below.

Secondary Heat Sensor
The heat sensor is located on back wall of the filter
compartment. This is the divider panel between the filter
compartment and the motor/valve compartments. It should
be visible between the first and second rows of filters without
removing the filters. For indoor units, the sensor is activated
if the temperature reaches 135 o F. For outdoor units, the sensor is activated if the temperature reaches 190 o F. It can
be tested using a heat gun directed towards the sensor.
If airflow is present the heat sensors and smoke sensors in
the valve compartment will be activated sooner. A signal is
sent to the controller to activate the rest of the fire
suppression system.
To reset the secondary heat sensor, the power must be
turned off and the sensor must be allowed to cool. The
internal program of the controller latches shut electronically, forcing the power to be cycled off and then
on. If the primary heat has been activated, the display will show “Heat2” as shown in the picture below.
Heat Detection Tubing
Heat Detection Tubing is a new fire detection system implemented by Clean Air Industries since January 2020. The tubing runs along the wall in the filter compartment. When temperature reaches 375 o F, the
tube bursts and immediately releases the fire suppression agent. The heat detection tubing is
implemented to allow the system to release the fire suppression agent even during power loss. The heat
detection tubing comes with pressure switch to monitor whether the fire suppression agent has been
released.

FSS Pressure Switch
The pressure switch monitors the pressure in the heat
detection tube. When the tube bursts, the pressure in
the tube will drop. This triggers the pressure switch,
which will then send signal to the PLC to let the PLC
know that the fire suppression agent has been released.
The fire suppression agent can also be actuated
electrically, when the fire pull is triggered, or when either
the primary or secondary heat detector detects heat
before the heat detection tubing melts.
Louvers
The louvers are located on top of the unit on the
intake and exhaust. They are pneumatically
controlled using solenoid valves. Activation of the
valve opens the louvers, deactivation closes. There
are indicator lights on the DIN connectors for the
valves to show if power is present or not.
The louvers are opened and shut using a pneumatic
cylinder. The cylinder has a spring extension so that
the loss of power will force the louvers shut. Check
valves are in place so that if compressed air is lost or
low, the louvers will not shut blocking air flow to the
unit. Compressed air is not required to close the louvers, only to open them due to the spring extension.
The door is sealed using bubble gasket. The seal is only to block air flow, and is not necessarily a 100%
seal.
The louvers close to prevent airflow when the fire suppression system is activated. On multi-module units,
louvers are used for each intake and exhaust.
