READ AND SAVE THESE INSTRUCTIONS
WARNING:
Disconnect from power supply before performing maintenance procedures
such as cabinet cleaning, changing filters or servicing of electric motor or
other electric components.
WARNING:
To reduce the risk of fire or electric shock, do not use this fan with any solid-
state speed control device.
WARNING:
For general ventilating use only. Do not use to exhaust hazardous or
explosive materials or vapors.
WARNING:
Use only a 15-Amp Fuse.
CAUTION:
Do not operate without having all filters in place.
Do not operate any fan with a damaged cord or plug. Discard fan or return to
an authorized service facility for examination and/or repair.
Do not run cord under carpeting. Do not cover cord with throw rugs, runners
or similar coverings. Arrange cord away from traffic area and where it will not
be tripped over.

GETTING STARTED
Initial set-up
1. Remove the GS3-200 unit from the packaging and locate and open the accessory box.
2. Open the GS3-200 cabinet and remove the protective packaging from the FA501D gas/odor filter(s).
Replace the filter into the cabinet noting the airflow direction arrow should point up.
3. The FA540B Pre-filter is preinstalled - simply verify the filter is in position.
4. Close and latch the front door.
Locating the air cleaner
Placing the GS3-200 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
Install the air inlet flange (labeled) to the air inlet port located at the back bottom of the GS3-200 cabinet. Secure
the port with the screws provided. Attach the hose to the inlet. Connect the hose to a Fumex suction hood or
place as close as possible to the pollution source.
Electric power
Locate the Fumex nameplate placed on the back of the cabinet to determine the power supply necessary. The
GS3-200 is factory configured for 90-120/1/50-60 or 220-250/1/50-60 and must only use a 15-Amp Fuse. Please
contact Fumex LLC. with any questions/concerns regarding power supply.
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 GS3-200 utilizes a variable speed blower with 8 speed settings. Press the up /down arrows to increase and
decrease the blower speed. Blower gradually increases in speed as “Up” arrow is pressed - some slight delay is
normal operation. Speed is indicated by the bar graph located above “BLOWER” label. A green light will indicate
that the blower is operating – no light indicates a blower failure or loss of power.
Filter monitoring
The GS3-200 utilizes pressure differential switches to monitor the status of the Pre-filter. Filter status is
indicated by the corresponding bar graph (“PRE” for part# FA540B). The bar graph will increase in 20%
increments until the filter is “loaded”. Red lights will indicate that a filter change is necessary.
The GS3-200 contains a VOC sensor to detect odors/gases in the exhaust stream.The system continually
monitors the exhaust stream which is indicated on the bar graph labeled “GAS”. When the gas/odor filter
becomes saturated and breakthrough of the VOC occurs the “GAS” warning light will illuminate.
GENERAL FILTER CARE
Fumex GS3-200 air purifiers feature a multi-stage filtration system designed to remove a wide range of pollutants
from the process plume in an extremely efficient, and cost-effective manner. Once the warning lights illuminate,
filters should be checked and clogged filters replaced.
STANDARD FILTERS:
Part # FA540B – Pre-filter Assembly
The pre-filter assembly is the first stage in the filtration process. Unique design minimizes
operator/maintenance personnel exposure to contaminants.
Replacement:
Filter life is highly dependent on the amount and size of the captured particulates. Average service life is 4-6
months.

Part # FA501D – 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(s) 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 receptacle. Replace the fuse as per the user servicing instructions
(use only 15-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 GS3-200 can be supplied with an optional interface package providing remote start/stop and filter monitoring
capabilities (Part # FA227).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”

RELAY ACTIVATION PROCEDURE FOR GS3-200 UNITS
CAUTION
DO NOT WORK ON PANEL WITH POWER APPLIED!
1. Disconnect all power sources from GS3-200 unit.
2. Locate 4 screws securing the top cover and remove cover.
3. Locate relay activation switch on the relay board as shown in Figure 2.
4. Flip the Relay Activation Switch to the “ON” position as indicated in Figure 3.
5. Reinstall top cover using the 4 screws removed in step 2.
6. Apply incoming power to the unit by connecting the power cord to an approved receptacle.Make sure the
blower is not running and the green power light is off. This is called the “Soft On” state.
7. Now that the physical switch is activated and the unit is in the “Soft On” state, the software will need to be
reprogramed via a flash drive with a configuration file and the USB port on the control board. (Contact Fumex to
acquire the correct configuration file for your unit).
8. Reprogram the software by changing the “remoteSwitchOnly” setting in the configuration file to “1”. This will
lock out the Control Board power button. The ON/OFF function will only be able to be controlled remotely.
9. After changing and saving the configuration file, plug the flash drive 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.)
10. 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.
11. 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 relay activation switch is turned on and the configuration file
has been reprogrammed the unit will only start by applying the proper
voltage to the start/stop relay.
