GETTING STARTED
Initial set-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 HEPA filter on top of gas/odor filter (NOTE: Pay attention to direction of airflow arrow).
9. Place the FA102B pre-filter on top of the HEPA filter.
10. Close and latch the lid.
11. Attach power cord to the power receptacle located on the lower rear of the cabinet.
Locating the air cleaner
Placing the FA1 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.
Inlet hose attachment
The FA1 unit ships 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.
Electric power
FA1 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 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 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 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 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 system utilizes a pressure
differential switch to indicate blocked / clogged filters. Once the warning lights illuminate, filters should be
checked and clogged filters replaced.
STANDARD FILTERS:
Part # FA102B Pre-filter Assembly
The pre-filter assembly is the first stage in the filtration process. The assembly is composed of high capacity
merv 11 rated filter media protected by polyester pre-filter. Unique design minimizes operator/maintenance
personnel exposure to contaminants.
Replacement:
The unique design of the pre-filter allows the filter to be changed as a complete unit or in heavy dust applications
the polyester pre-filter can be removed independently. Contact Fumex LLC. regarding any questions/assistance.

4
Part # FA100 HEPA Filter
The HEPA filter is 99.97% efficient in removing particles as small as 0.3µfrom 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.
GENERAL MAINTENANCE
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”.
Remote Interface and Connectivity Function
The FA1 can be supplied with an optional interface package providing remote start/stop and filter monitoring
capabilities (Part # FA228). Please see instructions below for Relay Activation/De-Activation procedures and
refer to the drawing in Figure 1 for remote connections.
WARNING
“To Prevent the Risk of Electrical Shock, Connect Remote Interface
Cable to 24v, Class 2 Power Supply Only”
WARNING
“Disconnect From All Power Supplies Before Servicing”
