GETTING STARTED
I n i t i a l s e t - up
1. Open all cartons and locate inlet, hose, hose clamps and wheels. Refer to Table 1 for the applicable part
numbers for your model.
2. Remove ALL filters and packing materials from cartons and the unit cabinet.
3. Place the unit on its side and install wheels in the bottom plate.
4. Attach the inlet to the top of the lid with the six screws provided.
5. Remove plastic wrap from gas/odor filter.
6. Carefully remove perforated cardboard from top and bottom of FA101D filter to expose “Green” media.
7. Place FA101D gas/odor filter into bottom of cabinet (NOTE: Pay attention to direction of airflow arrow).
8. Place FA100-2 HEPA filter on top of gas/odor filter (NOTE: Pay attention to direction of airflow arrow).
9. Place the FA102 panel filter on top of the HEPA filter (NOTE: Pay attention to direction of airflow arrow).
10. Place the FA103 pre-filter on top of the panel filter.
11. Close and latch the lid.
12. Attach power cord to the power receptacle located on the lower rear of the cabinet.
Loca t i n g t h e a i r c l eaner
Placing the FA1-Mini unit as close as possible to the pollution source reduces the amount of ducting needed,
reduces back-pressure, lowers power consumption, and improves overall performance. Placement should
minimize hose length and the number of bends. Use capture hoods with high efficiency entry whenever
possible. The unit exhausts through the bottom panel make sure to allow for adequate ventilation.
I n l e t h o s e a t t a c h m e n t
The FA1-Mini units ship standard with a 1 x 2”, 2 x 2” or 1 x 3” inlet. Attach flex hose over the metal air inlet tube
and tighten securely with the stainless-steel clamp. Connect the hose to a Fumex suction hood or place as close
as possible to the pollution source.
E l e c t r i c p o w e r
FA1-Mini is manufactured with a universal blower/motor assembly (90-250/1/50-60) and must only use a 10-Amp
fuse. Default power cord/plug is US (120V). Contact Fumex for additional information or options.
Confirm that correct power supply is available.

CONTROLS
On/Off Switch
Simple one touch controls –The green light above the POWER button will illuminate confirming power to the
unit.
Blower/Fan
The FA1-Mini utilizes a variable speed blower with three speed settings. Press the up and down arrow buttons to
increase/decrease blower speed. A green light next to the specific speed (Low, Med, or High) will indicate speed
setting. In the case of a blower failure, all 3 blower speed lights will flash. To reset the blower’s internal thermal
protection, disconnect the unit momentarily from its power source and reconnect. If the lights continue to flash
contact Fumex LLC. for replacement information.
Filter monitoring
The FA1-Mini utilizes a pressure differential switch to monitor the status of the particulate filters. The system
monitors across all filters simultaneously and the Red “FILTER” light will illuminate when one or more filters
need to be replaced. The recommended procedure is to first replace the Pre-Filter and then press the “FILTER
RESET”button. If the light remains illuminated or turns off and comes back on, then replace the HEPA filter and
press the “FILTER RESET”button.
The FA1-Mini contains a VOC sensor to detect odors/gases in the exhaust stream. When the gas/odor filter
becomes saturated, and breakthrough of the VOC occurs the “GAS” warning light will illuminate.
GENERAL FILTER CARE
Fumex’s FA1-Mini air purifier features a multi-stage filtration system designed to remove a wide range of
pollutants from the process plume in an extremely efficient, cost-effective manner. The sytem utilizes a pressure
differential switch to indicate blocked / clogged filters. Once the warning lights illuminate, filters should be
checked, and clogged filters replaced.
S T A N D A R D F I L T E R S :
Part # FA102 Pleated Panel Filter
Pleated panel filters are Merv 11 efficiency for use in removing particles as small as 10from the pollution
stream. Particles of this size are respirable and can cause respiratory problems in concentrations exceeding
OSHA mandated levels.
Replacement:
A pleated panels’ service life is determined by the volume of particles remaining in the air stream after passing
through the polyester pre-filter. When properly protected by the pre-filter, and depending on loading, pleated
panel filters service life is 4-6 weeks.

4
Part # FA103 Pre-Filter
The disposable polyester pre-filter is the first stage of the filtration process. Its main function is to remove dust
particles 100and larger in advance of the more expensive pleated panel filter.
Replacement:
The service life of the polyester pre-filter is determined by the type and volume of large particles collected.
Average service life is 4-6 weeks
Part # FA100-2 HEPA Filter
The HEPA filter is 99.97% efficient in removing particles as small as 0.3from an airstream.
Particles of this size are respirable and can cause significant respiratory problems.
Replacement:
A HEPA’s service life is determined by the volume of sub-micron particles remaining in the airstream after
passing through the pre-filters. When properly protected, and depending on loading, HEPA filters often provide
months of service. Average service life is 2-4 months.
Part # FA101D Gas/Odor Filter
Most process plumes contain several gases, some odorous –some not, some toxic at elevated concentrations
–some completely harmless regardless of concentration. To ensure employee safety the type and
concentration of pollutants must be determined. Please contact Fumex Engineering for filter selection
assistance. These filters utilize a blended activated carbon and activated alumina impregnated with KMnO4
filter to capture and treat gases/odors. This combination of materials provides protection across a broad range
of gases commonly found in industrial manufacturing processes.
G E N E R A L M A I N T E N A N C E
1) The blower motor is a sealed unit, 24,000 hr. MTBF rated. It is permanently lubricated and does not require
oiling –keep it free of dust accumulations to prevent overheating.
2) Remove any loose accumulations of dust/debris from the air filter chamber periodically.
“This product employs overload protection (fuse). A blown fuse indicates an overload or short-circuit situation. If
the fuse blows, unplug the product from the outlet. Replace the fuse as per the user servicing instructions (only
10-Amp fuse) and check the product. If the replacement fuse blows, a short circuit may be present, and the
product should be discarded or returned to an authorized service facility for examination and/or repair”.

RELAY ACTIVATION PROCEDURES FOR FA1-MINI UNITS
1. To activate the relays so the remote feature can be used the software will need to be reprogramed via a flash
drive with a configuration file (fumex.ini) and the USB port on the control board. (Contact Fumex to acquire
the correct configuration file for your unit).
2. Apply incoming power to the unit by connecting the power cord and turning the power switch located near
the power cord on. Make sure the blower is not running and the green power light is off. This is called the
“Soft On”state.
3. Reprogramming will lock out the Control Board power button. The ON/OFF function will only be able to be
controlled remotely.
4. Copy the fumex.ini file onto a flash drive and make sure it is the only file on the flash drive. If anything else is
on the flash drive the control board will not know which file to read.
5. Plug the flash drive with the desired fumex.ini file into the USB port on the front of the control board. (Make
sure the unit is in the “Soft On”state before plugging in the flash drive.)
6. Initially the light above the USB port will be red. After the reprogramming is complete the light above the
USB port will turn green and remain lit until the flash drive is removed from the USB port.
7. Remove the flash drive and apply 0-24 VDC to the start relay according to the wiring diagram in Figure 1 to
start the unit.
Once the relays have been activated the unit will only start by applying the
proper voltage to the start/stop relay.
RELAY DE-ACTIVATION PROCEDURES FOR FA1-MINI UNITS
1. To de-activate the relays so the remote feature cannot be used the software will need to be reprogramed via a
flash drive with a configuration file (fumex.ini) and the USB port on the control board. (Contact Fumex to
acquire the correct configuration file for your unit).
2. Apply incoming power to the unit by connecting the power cord and turning the power switch located near
the power cord on. Make sure the blower is not running and the green power light is off. This is called the
“Soft On”state.
3. Reprogramming will unlock the Control Board power button. The ON/OFF function will now be able to be
controlled at the unit.
4. Copy the fumex.ini file onto a flash drive and make sure it is the only file on the flash drive. If anything else is
on the flash drive the control board will not know which file to read.
5. Plug the flash drive with the desired fumex.ini file into the USB port on the front of the control board. (Make
sure the unit is in the “Soft On”state before plugging in the flash drive.)
6. Initially the light next to the USB port will be red. After the reprogramming is complete the light above the
USB port will turn green and remain lit until the flash drive is removed from the USB port.
7. Remove the flash drive and start the unit as described in the “Controls”section.
Once the relays have been de-activated the unit will only start by using the front
control panel. All relays will become non-functional.
